@Brock Man I may be speaking for a lot of people on how we can't simply thank you enough for the all knowledge you share. I myself can really appreciate all of your informative videos you share around your busy as hell schedule..Lol. Keep up the good work & God Bless you Brotherman..🤘🍻
Just bought my 2017 GSXR1000R here in Alberta Canada. @Brock, i am very pleased with all of your efforts for this project. I love how technical you go for us techy guys. I will be purchasing myself as well as promoting your services. Cheers
This S2B series is some of the BEST content on UA-cam. I love your scientific approach and keeping things honest. Your approach is definitely unique and appreciated. I'm looking forward to more content like this.
Just what I've been waiting on & great job. I was all but about to have you'll flash my 2017 GSXR 1000 last yr. But decided to wait to see what you done next. Glad I did. I'll be in contact here soon
Thanks Brock. You proved my tuner knows his shit. When I took my K7 Gixxer 750 in he told me to keep my PC3 to tune with the flash he did. He gave me the graph showing the bike when it arrived, after the flash and after the flash and PC3 map. Hell, he even emailed the PC3 map in case my PC3 ever fails.
See long description for video time tags and additional information. Please e-mail dynoroom@brocksperformance.com to inquire about flashes for YOUR bike. Our new website does not yet list all of our options.
hey Brock love your videos first off. but I was wondering if you might be able to help me with. I recently bought a 07 ZX10R it has what I believe to be a Gen 1 ZX10R exhaust from you on it. is there anyway to truly tell.
Brock Davidson Hey Brock. When you receive the new recalled ECM did you just download your same Flash with the power commander of the previous ECM that you already made or did you create a new Flash and map for the new Ecm. Also can you explain more about the studded in gears 2 and 3 because I never felt it on my bike when riding. Did it show up everytime you did a all gears run?
apexhunter2k - the power commander import did not and still will not work. We had to alter the new (post recall) ECM image to match our previous modifications/tune. The bike would not studder every time - it made a very strange sound. The dyno chart is available here: brocksperformance.com/content/brocknm/PDFS/GSXR1000_2017_Post_Recall_Test.jpg we suggest everyone obtain the recalled ECU.
I love the passion that you have for this and that you don’t give up when things may look the best but you make them even better. You squeeze as much power out of these bikes as much as you can!
Excellent series of videos, Brock ! A straightforward and detailed explanation of what you are doing and why. A benchmark for other UA-camrs to try and emulate.
Thank you from the UK brock I love your attention to detail I appreciate your info considering how much time all this takes you.. I can tell you put effort and care into your products.. look forward to more videos
Great video, thanks for the time and effort in producing and uploading it. I've been wondering whether to go ecu flash or PC5 on my 750. seeing this, I think I've decided PC5 for my requirements will be just fine. Yes, maybe a touch more outright power from a dedicated ecu flash but its going to be negligible gains over a Pc5, that will also be custom mapped for my bike anyway. Great video.
@peter - The imports aren't usually THIS bad (as mentioned, this bike is a special case). That said, I haven't found one that will drop in and meet our standards. (not even close, in fact)
Yeah this is an old video but I've just bought a woolich programmer/logger and am in the process of tuning my own bike. I'm technically minded and the systems are pretty straightforward if you're patient and dont' change things without understanding the impact. I like that you're honest about the power commander vs flash situation. I also like that you're honest about the time it takes to develop a good flash map but that it's also worth it in the long run. Luckily for me with woolich specifically I can just ride around with the logger plugged into the bike and then load it into the software and adjust based on the logged AFR readings. Once people start to realise that these systems are as easy as a DIY oil/filter change and less complicated than throttle body syncing we might find more people prepared to go down the DIY route. Especially those that do their own servicing.
Do you do anything else to modify your results from the auto tune? I have the same setup on my gsxr but I didn’t really find good instructions how to use it. I’ve just been playing around with mine and my bike works fine but I’m not sure if I’m using it right.
Very interesting Video .. I installed a Boon docker fuel controller and an Oxygen gauge on my Yamaha snowmobile because it ran way to rich stock .. My Boon docker does not control timing but a 4 degree offset keyway really improved my MPG and HP by just a little .. It's an R-1 engine that turns 10.500 RPM .. It's great to know how close stock timing is to perfect . I have never worked with electronic fuel injection so of course I wondered how accurate and close the controls are how precise the injectors are ect.. there must be a lot of variables in flow .. I deal would be 4 oxygen seniors 4 spark knock sensors and active tune controls for each cylinder.. Seems an onboard Oxygen gauge would be handy .. Looks like your videos make a great sales pitch for the active tune system... For a street bike it seems like you can have the best of both worlds great wide open full power yet could cruising mpg .. Your first gain of you explained is to get away from being too lean as stock bikes are..
Hello Brock, thanks for sharing this valuable information. Finally found for what I was looking for. Very well and clear presented. Keep up doing the good work! I am a fan now. Whish you all the best from The Netherlands.
My gsxr1000r 2017 sometimes the auto blip doesn't want to blip from 6th gear back to 5th. Sometimes it will double blip. What should i do? No error codes were found at all. Only happens from 6th gear back to 5th and from 5th gear back to 4th gear. Best auto blipping only happens when The RPM is higher than 3500. Very rare. Is it a Voltage drop situation? Thank you from Thailand.
Sounds like your chain is too loose - when this happens, the resulting backlash will not allow the shifter to function properly: ua-cam.com/video/-cgGG2Vh7qg/v-deo.html
Get a base line run in the quarter mile before the LONG, LOW, and LIGHT method takes effect love the videos please let’s teach 650ib roll on races down the interstate is nothing compared to a dead stop launch we need to further our sport Maybe you’ll make the man cup in April ??? SGMP is my home track
I was in my local shop in Elizabethtown Ky and was talking to Lori behind the desk at Etown Powersports and she said she knew you very well, we are getting a Brock’s penta carbon full system for my 2023 GsxR 1000 and her husband Cory is gonna tune it with a power commander. Small world….I never knew they could be tuned for hp just by a power commander.
We can tune it to be much better than stock using the PCV, but It needs to be flashed also to try to keep the throttle blades open 100%. I say try because BMW's Bosch ECU's don't work like the Suzuki's Denso unit - you can't just jump in and tell them what to do.
I really enjoy these videos Brock!!! Very, Very informative and you make them really interesting, and enjoyable to watch. Very good. (I said in an earlier comment, that I'd gotten an 2006 ZX-10R, Deal fell through---Worked better for me, cause now getting although a 2015 it is Brand New a ZX-10R Anniversary Edition---I Love the Kawi Green, it is the mostly Green Model{I have seen ones with Black tanks and more black, maybe they aren't anniversary Models don't know} Looking forward to a Titanium Mid Pipe and a Stupid Fast Exhaust from your company. Will need to save some first though. Got a Very Good Price on it, or would have gotten another Gixxer--had an original GSX-R750 back in the mid 1980's was my first truly fast bike, Don't mean to take away from you, not at all, Keep the great Videos coming!!! :)
Thanks for a such useful series. Respect! I know that you use FT and this service have much useful features. I think you know or even maybe use Whoolich racing ECU software it can accept online datalogin and autotune mode. Very interesting to hear your feedback about it.
How about changed the Secondary injector balance map ? Would be interesting , the woolich software looks to be slightly ahead of the flash time with auto tune etc
what euro4/emissions things (particule filter, sensors, software etc) did you end up deleting and changing? The s1000rr for example gains top end when blocking the nox sensor and relocating the air temperature sensor to further out the airbox. what kind of things do you think thr gsxr would benefit from?
Hey Brock, just came across this video and first have to say awesome job very much enjoy your videos and all the knowledge you put out there thank you sir. I do I have a question though you said there isn’t a problem with ecu fuel tuning but just with this bike specific. Have you seen or know if there is an advantage to running a power commander in combination with guhls flash on a 14r? I will be purchasing the AH2 full system in the next few days and was just going to send my ecu back to don to have the fuel corrected for the new exhaust, now I am wondering if I should have the fueling flashed back to stock and get a PCV lol thanks in advance.
@Playrich - there is a problem with this particular bike...but there are also many others. There is a long list of variables (too many to list, and highly technical) that determines the best know configuration for a particular model. We are experts on your 14R and have record-setting combinations from drag racing to land speed as a result of our combinations. If you would like to achieve our results, you will need to purchase our products. Here is more info. including a young lady who set a record of 212 MPH using only our bolt-on products and tuning. blog.brocksperformance.com/kawasaki-zx-14r-12-16-information-page/
Thanks Brock! Epic series. Loved all of them. Question about humidity, if your dyno room was air conditioned could you get consistent results within a small percentage? I had my bike dynoed on a humid wet day and I cant say its perfect, would the humidity have been a factor?
The amount of energy needed to truly heat or cool a dyno with a smoking hot bike running inside is tremendous. We built our room inside a 12K square foot warehouse and use the temperature of the floor and concrete floor and surrounding components to help cool the inlet temps a bit. That said, in the heat of summer, that room might as well be located in the parking lot. We have seen 108 degree ambient room temps in the summer. The sensors on your bike allow a wet/humid summer map to work well year round. We do have hot weather maps for some bikes.
Hi Brock, great videos BTW, if I missed seeing it I apologize but does disabling the "deceleration fuel cut" smooth out any off/on snatch in the throttle response ? Thanks
That map is in speed density which has super weird numbers vs a VE based map. On top of that if you need to find your difference in percentage you do HAVE/WANT. For example is your target is 13.2 at a certain spot, but your running rich at say 12.7. You do 12.7 divided by 13.2 which equals 0.96 which means 4% needs to be taken out. If it were the other way around. Being lean 13.2 and needing 12.7, 13.2/12.7=1.039 or 3.9% fuel needs to be added. Call it 4%.
Not to the common guy without any engineering background ;) - The Gen 1 ZX-14 is the ONLY bike we have ever confirmed as drag raced during development. It has one of the best clutches for drag racing - period. It doesn't need a mod, but our stronger springs and spacers do help - especially with larger riders, displacement or power adders: brocksperformance.com/clutch-spring-kit-w-280-thick-spacer-zx-14-06-11/
@@BrockDavidson also with lambda its the same figuring out what percentage to pull/add. Have over want. IE have 0.85 lambda want 0.80 lambda = 0.85x0.80=1.062 so adding 6% will get me to my lambda I want. Also I know when I do the division if I see a 1.xxxx that means it needs fuel added. If I see 0.xx that means I need to take away. And best part is if your tuning software allows multiplication, you can type that value straight in, *1.06 for adding 6% or *0.94 for removing 6% for that cell(s) value. Or vice versa. Have 0.80 lambda, too rich, I want 0.85. 0.80/0.85=0.94 or I’m taking away 6% fuel. Greatest thing about lambda as you already know, doesn’t matter what stoich is of the fuel you’re using 1 is always stoich etc. makes it so much easier. I love using lambda instead of the typical gas scale. If for whatever reason you want to convert the lambda to AFR that’s rather simple as well. You times the lambda value you have by the stoich of your fuel. So if I’m using regular ole gasoline, I’m at 0.85 and I want to for whatever reason, know what that is afr wise, I’ll do 0.85x14.7=12.495AFR, or if I’m using Q16 with a stoich of 13.33 0.85lambda would be 11.33.
Hi Great to see and learn from your video, I just have a question I have MIVV full system exhaust, PCV and Stock airfilter on my CBR 650F I dynoed my bike to see the power output which is 81bhp saw another video where in the guy has flashed his ECU and his bike is showing 96 bhp , just want to know can I still flash my ECU from the same tuner keeping my PCV also working with same. Is it really possible to keep both
Glad you like our vids. Yes. As long as the fuel tables in the ecu are not altered, your pcv and maps will work like they do now. Please note, you will probably need additional pcv mapping after ecu derestriction.
Brock,thank you for very informative videos! Tell me please, how to tune bikes with ram air intake? Do I have to tune them richer at high rpm and how much? Thank you!
Glad you like. Please contact sales@brocksperformance.com for questions on products or dynoroom@brocksperformance.com about ECU Flash specifics. We are always willing to point you in the right direction.
Hi Brock, I’ve been following your stock to brock series very closely. I’m currently working on a 2017 GSXR1000R with Bazzaz ZFi & FTecu flash. I’ve taken a look at the throttle plate mods which is already in place for the ECU number I’m using so I’d be expecting not much power gain from a base run I did on the dyno. As mentioned earlier, the bike is running on Bazzaz ZFi, FTecu flash (EU flash), sprint air filter, decat with SC project end can. Do you know as to why I am not able to achieve a power gain despite the above? Stock: 168-170hp
Hi Brock... i've been watching from the begining and starting on the 190hp, passing by the 204 and now 190 again it sounds kinda strange... however, it's not all about HP... i noticed you never mentioned anything about torque, it is because you don't find it relevant for your tune or because you simply decided to ignore it...?
@MrGuerra - we have mentioned torque as the force that accelerates the vehicle from the beginning of the series. That said, we find that it's not easy for the average person to relate to this increase. In episode 2, we made 165.73 RWHP SAE- in E7P2, we are now at 194.14 RWHP SAE (an increase of 17.5%). It's fairly easy for most to understand that we now have a MUCH faster motorcycle. If I told you that we gained 6.19 ft-lbs of torque (a 7.5% increase) over that same period - would you understand this to mean the EXACT SAME performance gain? We will get into torque multiplication, and it's benefits (or downfalls) in more detail once we get to the drag strip.
Always have, and probably always will use a PC5 on top of my flash for quick adjustments at the track. Far too many tracks out there that lack a decent enough internet signal to flash the ECU successfully
Brock, have you happened to see what the top speed on the dyno with the stock sprockets on these 17+ gixxer 1000 is by chance? I can't seem to find what the gearing limited top speed is anywhere!? I want to drop a tooth in the front and I'm trying to calculate how much top speed I could potentially lose. If any.
Hi Brock, my local tuner in the UK keeps telling me to go the ecu flash route to sort out the fuelling etc, In your opinion is a Power commander the better route or should I go with the ECU remap? Thanks Mike.
Can you explain why @5:50 we see the map numbers jump from 16 to -5 within 250RPM? I would expect to see much less variance between numbers and see a smoother transition. Fantastic series btw love your work. I have a 2010 gsxr 750 with straight pipes (no cat), M4 and a power commander 5. I bought it with a dyno tune on it with a custom map but I am not sure if it had a custom ECM tune as well (have the printout though). - just looks odd when I see the trim numbers change so drastically.
Also, can you explain how the gsxr's have a power mode switch (A/B/C setting) affects the maps/AF ratios? - I am unclear what the power mode switch actually does. (retard timing?, change AF maps?) My spider sense tells me that if you muck with the modes it is going to affect the air fuel burn which is going to throw the map out because the map is tuned for a specific config.
Large jumps in small rpm's are required to keep the AFR correct throughout the range. This is common when a precise AFR measurement, under load, is observed. This doesn't happen in the stock ecu mapping... Which is why stock ecu mapping works so poorly. If you add a wideband sensor to your pipe and go for a ride, you will see the same results, once corrected.
@@BrockDavidson Thanks Brock! I have rebuilt many car engines from full tear downs but the whole Air fuel thing was a complete mystery to me. After seeing the first video I binged the whole series like I was watching breaking bad for the first time. I am hooked. absolutely fantastic. You are a master in your craft!
Hi Brock, I own a 2015 ktm superduke. I left the stock headers but I replaced the catalyser with a link pipe and I have the Akrapovic slip on , I saved around 10 pounds ( 7 pounds from the catalyser and 3 from the slip on ) I didn’t replace the headers because It was way cheaper to take off the cat then to buy the 2 grand full line. I also removed the stock air box and installed the Rottweiler air box ( way more air comes in ) I installed a power commander 5 and an ignition module and had it tuned on the Dyno. I do feel that the bike is more powerful but I find that when the weather is hot and humid the bike doesn’t perform as well ( not even close ) to when the weather is cooler. Do you think that installing an Auto Tune would fix that problem? Another Question: do you think that the setup of my exhaust without the full Akrapovic header was a good idea? I mean do you think that the Akrapovic headers would have increased the performance? Cause in my point of view it basically ends up being equally the same. Thanks
petelpete - headpipes are the part of the exhaust that improve horsepower - a slip-on improves the look and sound. As far as hot/humid weather - some bikes compensate for it better than others. You can create your own -5% across the board 'hot weather' map and select between it and the map you are using by installing a map selector switch: brocksperformance.com/dynojet-map-selection-switch-power-commander-v/ if you had your bike tuned by a competent tuner, you should not need an autotune unit.
Good stuff brock. The gsxr is coming along good. Quick question: I have an 06 gsxr 1000. Would you recommend tuning with a pcV or flashing the ecu? Thanks
Both if you would like flexibility in your tuning. Flash alone if you want set and forget. Contact dynoroom@brocksperformance.com - we have a flash for your bike,
Brock Davidson Thanks. Originally with a full titanium m4 GP exhaust with a teka box tune, produced 153rwhp and 80ft/lb torque. With your full alien head exhaust and pcv tune, produced 163rwhp and 78ft/lb torque. Just curious if flashing the ecu would produce more power than the pcv for my bike.
I just buy bike K5 1000 with almost 50000 miles on it, dont know history, bike was already dyno mapped i have dyno print. Custom mapping here cost 450$. I am just street rider, enthusiast which want just that bike run smooth. For 450$ I can buy pcv and auto tune. Can you advice pcv to go or again custom dyno tune? Do you block PAIR system?
I’m trying to wrap my head around ECU flashing vs a power commander. I have a tiger 660 and just installed a Zard full exhaust. I want to tune the bike now and debating whether to flash, install an power commander or both. What do you recommend. Also can I stick to the sock air filter or do I need to upgrade with the tune. Thanks
So brock I'm confused when you talk about the exhaust on the bmw and the gsxr you said you went with the alien head cuase your going drag racing but if you wanted more midrange torque you would go for the predator. I thought midrange is exactly what you want to be better for drag racing doesn't the midrange help with acceleration?
@Jock - Great question. In drag racing and land speed, the bike spends almost all of its time in the high revs and WOT. We can make simple gearing adjustments if we want more torque or more speed. Dropping 1 tooth on the countershaft has more of an effect on acceleration than we could ever build into an exhaust. In road racing, the bike spends most of it's time with the throttle partially open, especially on short courses - this is where a broader power/torque range is most benefitial.

HI Brock The FI on all Honda CBR from 2008 when started commence moving the timing forward in large increments automatically and will continue to advance untill the knock sensor detects knocking, when knocking is detected the ecu retards the timing by the last increment and then rechecks, if a knock is not detected then the timing will advance in smaller increments unit again a knock is detected. This continues untill the max timing advance is achieved and no knock is detected. This process occures each time the bike is started. It is designed to get the best advance setting regardless of fuel used, considering this, is possible to flash a different timing map on a CBR 1000rr or flashing a Honda only involves the fueling?
@Sebastain - In the past we 'tricked' the ECU into not allowing this to exist by using a Bazzaz Z Bomb: www.bazzaz.net/index.php/z-bomb/z-bomb-cbr1000rr-08-14 - today, this can be incorporated into the ECU flash.
I'm told repeatedly to gut the air injection system in order to dyno tune. If it doesnt fool the stock ecu and o2 sensor why would it bother a dyno tuner? To me the air injection helps keep everything from exhaust valves, o2 sensors and exhaust piping cleaner and lasting longer and not carboned up. The best tool is a motivated tuner, if he doesn't like you or just wants to get your bike done, that's it.
The O2 sensor (s) is there ONLY to measure cruising speeds to allow the bike to meet strict emissions regulations. As soon as the bike moves out of this cruising area (@7.5K+ and 20%+ Throttle)...it moves to static (no adjustment from O2 sensor) maps stored in the ECU. As soon as you make changes to your bike that require fuel remapping (aftermarket exhaust, high flow air cleaner, race fuel etc...) you will need to measure the AFR in these areas and make adjustments to the static fuel mapping (via PCV/Bazzaz/Rapidbike/ECU fuel tuner etc...). If the Pair is functional, the actual AFR is corrupted by the PAIR adding air into the exhaust port. This air is only required to increase the heat in the stock converter - in race applications using full systems, it's an unwanted/unused/undesirable nuisance to tuning. Example: actual AFR is 12-1...but PAIR valve inserted air mixing with the exhaust gasses FOOLS the tuners measuring device into reading 14-1. Common sense says the tuner will adjust the fuel down to the desired reading - let's say the tuner is shooting for a 13.2-1 AFR. If the PAIR is functioning, the actual AFR was just accidently tuned to an undesirable 11.2-1. Power is lost, emission readings are up and the bike runs like pooh and huffs black clouds of smoke, even though the tuners measuring device shows it's a perfect 13.2-1. This is why the PAIR MUST BE BLOCKED when tuning for performance. As far a "cleaner"...sure, but it comes at the expense of poor drivability, poor acceleration and decreased top speed as well as the "deceleration pops" (mini internal exhaust explosions) and excessive heat destroying your expensive aftermarket exhaust. FYI: OEM exhausts are heavy and sound like they do because they use metal internal baffles that won't fail from the additional heat required for clean air regulations. Aftermarket exhaust use thinner/lighter material as well as fiber baffles to produce more power as well as the sound performance enthusiasts desire. I hope this helps you better understand why the PAIR must be blocked in performance applications, especially when tuning.
@Brock - I don't know too much about drag racing, time to peak power clearly in the GIxxer's favor, but does that mean the BMW would be catching back up at the end of track, all other things being equal?
@Getis - Our GSX-R 1000 currently tops out on the dyno at around 183 MPH (OEM tire/gearing/peak rev limit, etc) The BMW will run @195 MPH with the same set-up. It would also depend on how long your 'track" - the BMW's speed would show up in a standing mile - not in a 1/4 mile.
@Brock - There are some guys from a Ducati V4R video who refuse to believe the Suzuki makes this power. They keep giving me the business about how my dyno guy is lying to me. Oh man, I can't stop laughin at these people. As if Brock Davidson, the man himself, is going to compromise his business by lying and selling products that don't work? Dang, it's hard to understand people sometimes. I try to tell them that Suzuki is making their power by VVT, among other things, while Ducati is making it old school, by installing a high lift cam, which of course will likely shorten the engine's lifespan when comparing apples to apples. The claim is the V4R makes 199 and I said I can't justify $40K for for 4-5 more HP, just get the Gixxer with aftermarket goodies added on for under $20k. They didn't like that very much - hahahaha
@Getis we have not had the V4 on our dyno yet, but I understand they run strong. They would need to be VERY strong to pull 198 on our dyno... but who knows? We usually adjust negative attitudes with a trip to the race track... they understand better afterwards ;)
Great videos !!!! One question, I have the s1000rr. I have a Rapidbike installed. Have you ever dynoed a bike with a Rapidbike installed ??? I'm curious to know if the AFR is on point ( smooth flat line).
I have a power commander and a plug and play quick shifter both Dyno jet brand. Auto-tune and unplug or auto tune keep it plugged or Dyno customized map? Thanks if you reply.
Either. It can stay plugged in, it only makes changes to the map when you tell it to. If you have a good base map, you shouldn't need it...if you dont, it can help. Hope this helps you.
With the inability to get a flash for a 2021ZX10R would you suggest a rapid tune or bazazz or a pcv or is there any way to tune through the stock locked ecu
Sorry, in this video you apply table(pcv5) to Fuel maps..but table pcv5 got only 10 columns(throtle positions) ECu flesh got so much more throtle positions(columns) so how they transform
Maps average between columns when viewed as a percent. If the secondary injector percentages are the same, the map import works ok. As soon as the secondary percentage changes, the import does not work well. This is why we adjust by hand in these areas.
@Brock Davidson does this bike have a knock sensor? I went back and looked at FTECU unrestricted map and it has many small changes in the ignition timing. Im 240lb rider and I absolutely have a hard time redlining it in 6th with every mod in this series (almost) and theres many, many videos of people grabbing this bike stock and easily rev limiting this bike in 6th... easily achieving even a top speed of 301km/h 100% stock. My friend has been working on stuff for a long time and I went over a long conversation about this and he suggested because of the advanced ignition timing it could be knocking and the knock sensor limiting the engine making it hard to reach rev limit. I'm really not sure why they have advanced ignition timing in their basic unrestricted map for download... The only thing I wanted was open throttle blades and no top speed limit. That's my other question. Will it have a top speed limit of 186 if I change the stock maps manually and ecu settings myself? I don't see an option for top speed limit in the files anywhere so im not aware how they do that. I'm pretty sure the cluster is locked to 186mph also?
@william. The bike does not have a knock sensor - Per our videos, our mapping also does not include any ignition timing adjustments. FTECU should be able to help with your questions regarding changes to their maps. If you have questions about using Brock's Products, please feel free to contact me personally at bmail@brocksperformance.com

Watching this episode again and I am STILL learning things I missed on my first watch
Welcome back!
Thanks Brock. You proved my tuner knows his shit. When I took my K7 Gixxer 750 in he told me to keep my PC3 to tune with the flash he did. He gave me the graph showing the bike when it arrived, after the flash and after the flash and PC3 map. Hell, he even emailed the PC3 map in case my PC3 ever fails.
I can't believe this was 3 years ago seams like yesterday theses videos came out.
DUDE seriously. I remember anxiously waiting for the next episode like it was a t.v. show
@@kayhoww Brock Davidson is the man if i was a motorcycle I'd only want him to work on me.
I wish you did series like this with an oldschool gixxer with carbs. This is amazing material though, keep rocking Brock!
Mind boggling stuff, just amazing how you can understand it all
Wait until you see the next vid ;)

hey Brock love your videos first off. but I was wondering if you might be able to help me with. I recently bought a 07 ZX10R it has what I believe to be a Gen 1 ZX10R exhaust from you on it. is there anyway to truly tell.
@Jeremy - our customer support staff can help you with that question: sales@brocksperformance.com
Brock Davidson Hey Brock. When you receive the new recalled ECM did you just download your same Flash with the power commander of the previous ECM that you already made or did you create a new Flash and map for the new Ecm. Also can you explain more about the studded in gears 2 and 3 because I never felt it on my bike when riding. Did it show up everytime you did a all gears run?
apexhunter2k - the power commander import did not and still will not work. We had to alter the new (post recall) ECM image to match our previous modifications/tune. The bike would not studder every time - it made a very strange sound. The dyno chart is available here: brocksperformance.com/content/brocknm/PDFS/GSXR1000_2017_Post_Recall_Test.jpg we suggest everyone obtain the recalled ECU.
Brock Davidson ok cool, thanks
194 hp on pump gas still makes me just chuckle with stupid uncontrollable joy!
I love the passion that you have for this and that you don’t give up when things may look the best but you make them even better. You squeeze as much power out of these bikes as much as you can!
That's how old racers work ;)
Brock Davidson do you recommend a power commander or a ecu flash tune (still on the dyno) for a 2017 Honda cbr 1000rr?

Another great video. To get a glimpse of all the effort you go to, to get the best out of this bike is great.
Thank you
Excellent video, Brock. Well explained, and shows the intricacy (and complexity) of getting a really great tune. Thanks!
Excellent series of videos, Brock ! A straightforward and detailed explanation of what you are doing and why. A benchmark for other UA-camrs to try and emulate.
Thank you from the UK brock I love your attention to detail I appreciate your info considering how much time all this takes you.. I can tell you put effort and care into your products.. look forward to more videos
Thanks so much for sharing...so much hard work went into this...you truly are amazing. You cleared up so many questions I had...👍
Cheers mate. Cannot wait for the track work. Wow man wow.
Great video, thanks for the time and effort in producing and uploading it. I've been wondering whether to go ecu flash or PC5 on my 750. seeing this, I think I've decided PC5 for my requirements will be just fine. Yes, maybe a touch more outright power from a dedicated ecu flash but its going to be negligible gains over a Pc5, that will also be custom mapped for my bike anyway. Great video.
Hi Brock had no idea that an imported fuel tune from PCV would be so different inside the ECM, thanks for the knowledge and video again
@peter - The imports aren't usually THIS bad (as mentioned, this bike is a special case). That said, I haven't found one that will drop in and meet our standards. (not even close, in fact)
Favourite current series on UA-cam thank you for sharing Brock
Yeah this is an old video but I've just bought a woolich programmer/logger and am in the process of tuning my own bike. I'm technically minded and the systems are pretty straightforward if you're patient and dont' change things without understanding the impact.
I like that you're honest about the power commander vs flash situation. I also like that you're honest about the time it takes to develop a good flash map but that it's also worth it in the long run. Luckily for me with woolich specifically I can just ride around with the logger plugged into the bike and then load it into the software and adjust based on the logged AFR readings.
Once people start to realise that these systems are as easy as a DIY oil/filter change and less complicated than throttle body syncing we might find more people prepared to go down the DIY route. Especially those that do their own servicing.
Do you do anything else to modify your results from the auto tune? I have the same setup on my gsxr but I didn’t really find good instructions how to use it. I’ve just been playing around with mine and my bike works fine but I’m not sure if I’m using it right.
I am glad you're only 4 hours away from where I live I will be having you work on my new bike!!

Excellent explanation of this, and I truly appreciate that!
It really is a masterclass. It almost feels like you are telling too much from the kitchen.
But really Brock- props to you! What a stud
Very interesting Video .. I installed a Boon docker fuel controller and an Oxygen gauge on my Yamaha snowmobile because it ran way to rich stock .. My Boon docker does not control timing but a 4 degree offset keyway really improved my MPG and HP by just a little .. It's an R-1 engine that turns 10.500 RPM .. It's great to know how close stock timing is to perfect .
I have never worked with electronic fuel injection so of course I wondered how accurate and close the controls are how precise the injectors are ect.. there must be a lot of variables in flow ..
I deal would be 4 oxygen seniors 4 spark knock sensors and active tune controls for each cylinder.. Seems an onboard Oxygen gauge would be handy ..
Looks like your videos make a great sales pitch for the active tune system... For a street bike it seems like you can have the best of both worlds great wide open full power yet could cruising mpg ..
Your first gain of you explained is to get away from being too lean as stock bikes are..
Did somebody say "Carbon Fiber Wheels!" Oh boy, when this thing hits the drag strip, it is going to be insane!
Thank you for the time it takes to make these vids. Great info!!!
Hello Brock, thanks for sharing this valuable information. Finally found for what I was looking for. Very well and clear presented. Keep up doing the good work! I am a fan now. Whish you all the best from The Netherlands.

Hello from Panama thanks for teach all these thinks i want be your student i am learning a lot in your videos. Thanks mister brock
You are very welcome
yes sir let's take it to the track
Very informative Brock thanks!
This stuff is fascinating as hell. I'd like to get my FZ-07 Tuned sometime :-)
great info..thanks a lot.
My gsxr1000r 2017 sometimes the auto blip doesn't want to blip from 6th gear back to 5th. Sometimes it will double blip. What should i do? No error codes were found at all.
Only happens from 6th gear back to 5th and from 5th gear back to 4th gear. Best auto blipping only happens when The RPM is higher than 3500. Very rare. Is it a Voltage drop situation? Thank you from Thailand.
Sounds like your chain is too loose - when this happens, the resulting backlash will not allow the shifter to function properly: ua-cam.com/video/-cgGG2Vh7qg/v-deo.html
@@BrockDavidson Thank you so much. Greetings from Thailand. 🙏🤘
Another very informative video
I am definitely going "stock to Brock!!"
Get a base line run in the quarter mile before the LONG, LOW, and LIGHT method takes effect love the videos please let’s teach 650ib roll on races down the interstate is nothing compared to a dead stop launch we need to further our sport
Maybe you’ll make the man cup in April ??? SGMP is my home track
Great episode keep em coming
New video soon?? Will the next videos show the difference between stock rim weight and BST's they would look sick on her!
Uncle Brock 😎😋😂🕺💃🕺💃🕺💃
Awesome video as always- My Bike is "stupid fast" already otherwise i would definatley be a customer.
One of the limitation WRT TP - old school...
When is the next video coming???
damn, that's a lot to learn about dyno tuning Brock. :O
If it were easy... everyone would be good at it :0)
I was in my local shop in Elizabethtown Ky and was talking to Lori behind the desk at Etown Powersports and she said she knew you very well, we are getting a Brock’s penta carbon full system for my 2023 GsxR 1000 and her husband Cory is gonna tune it with a power commander. Small world….I never knew they could be tuned for hp just by a power commander.
I've known Cory and Lori for years - fantastic people for sure! You are in great hands with them👍👍
The 12krpm flat spot on bmw can be totally fixed with PVC? Or it does it need a flashing ecu also? Thanks In advance
We can tune it to be much better than stock using the PCV, but It needs to be flashed also to try to keep the throttle blades open 100%. I say try because BMW's Bosch ECU's don't work like the Suzuki's Denso unit - you can't just jump in and tell them what to do.
This man knows his shit
Great Vids Brock, really interesting!
I really enjoy these videos Brock!!! Very, Very informative and you make them really interesting, and enjoyable to watch. Very good. (I said in an earlier comment, that I'd gotten an 2006 ZX-10R, Deal fell through---Worked better for me, cause now getting although a 2015 it is Brand New a ZX-10R Anniversary Edition---I Love the Kawi Green, it is the mostly Green Model{I have seen ones with Black tanks and more black, maybe they aren't anniversary Models don't know} Looking forward to a Titanium Mid Pipe and a Stupid Fast Exhaust from your company. Will need to save some first though. Got a Very Good Price on it, or would have gotten another Gixxer--had an original GSX-R750 back in the mid 1980's was my first truly fast bike, Don't mean to take away from you, not at all, Keep the great Videos coming!!! :)
Thanks for a such useful series. Respect! I know that you use FT and this service have much useful features. I think you know or even maybe use Whoolich racing ECU software it can accept online datalogin and autotune mode. Very interesting to hear your feedback about it.
Talking about old school, damn those carbs!!!
Fu**ing Master Bro !!! really great job
How about changed the Secondary injector balance map ? Would be interesting , the woolich software looks to be slightly ahead of the flash time with auto tune etc
We changed it - we would have to get out of my 'comfort zone' (40-50%) to get anywhere close.
Thank you
I would like to know how the 2018 zx10rr would stack up against both the s1000rr and the gsxr1000.
Great video new subscribe here going to check out more of your stuff super cool
Dude your awesome with this shit brock. I so wish you had something available for my 04/06 R1
what euro4/emissions things (particule filter, sensors, software etc) did you end up deleting and changing? The s1000rr for example gains top end when blocking the nox sensor and relocating the air temperature sensor to further out the airbox. what kind of things do you think thr gsxr would benefit from?
Great video
hello master Brock, does fuel accelerator setting will change the afr ? thanks brock.
Hey Brock, just came across this video and first have to say awesome job very much enjoy your videos and all the knowledge you put out there thank you sir. I do I have a question though you said there isn’t a problem with ecu fuel tuning but just with this bike specific. Have you seen or know if there is an advantage to running a power commander in combination with guhls flash on a 14r? I will be purchasing the AH2 full system in the next few days and was just going to send my ecu back to don to have the fuel corrected for the new exhaust, now I am wondering if I should have the fueling flashed back to stock and get a PCV lol thanks in advance.
@Playrich - there is a problem with this particular bike...but there are also many others. There is a long list of variables (too many to list, and highly technical) that determines the best know configuration for a particular model. We are experts on your 14R and have record-setting combinations from drag racing to land speed as a result of our combinations. If you would like to achieve our results, you will need to purchase our products. Here is more info. including a young lady who set a record of 212 MPH using only our bolt-on products and tuning. blog.brocksperformance.com/kawasaki-zx-14r-12-16-information-page/
Brock, is there a reason why you wouldn't use Dynojet's Autotune module for AFR correction and datalogging?
Thanks Brock! Epic series. Loved all of them. Question about humidity, if your dyno room was air conditioned could you get consistent results within a small percentage? I had my bike dynoed on a humid wet day and I cant say its perfect, would the humidity have been a factor?
The amount of energy needed to truly heat or cool a dyno with a smoking hot bike running inside is tremendous. We built our room inside a 12K square foot warehouse and use the temperature of the floor and concrete floor and surrounding components to help cool the inlet temps a bit. That said, in the heat of summer, that room might as well be located in the parking lot. We have seen 108 degree ambient room temps in the summer. The sensors on your bike allow a wet/humid summer map to work well year round. We do have hot weather maps for some bikes.
Hi Brock, great videos BTW, if I missed seeing it I apologize but does disabling the "deceleration fuel cut" smooth out any off/on snatch in the throttle response ? Thanks
You gotta try E30-E85 fuel next! If the injectors can flow enough fuel that is. Cheap race gas?
That map is in speed density which has super weird numbers vs a VE based map. On top of that if you need to find your difference in percentage you do HAVE/WANT. For example is your target is 13.2 at a certain spot, but your running rich at say 12.7. You do 12.7 divided by 13.2 which equals 0.96 which means 4% needs to be taken out. If it were the other way around. Being lean 13.2 and needing 12.7, 13.2/12.7=1.039 or 3.9% fuel needs to be added. Call it 4%.
We use lambda here. It's just not easy to explain.
@@BrockDavidson shit lambdas even easier lol! And yea definitely I understand. Btw do you guys not have a clutch mod kit for the gen 1 zx14?
Not to the common guy without any engineering background ;) - The Gen 1 ZX-14 is the ONLY bike we have ever confirmed as drag raced during development. It has one of the best clutches for drag racing - period. It doesn't need a mod, but our stronger springs and spacers do help - especially with larger riders, displacement or power adders: brocksperformance.com/clutch-spring-kit-w-280-thick-spacer-zx-14-06-11/
@@BrockDavidson awesome thanks for the reply’s and your time sir greatly appreciated
@@BrockDavidson also with lambda its the same figuring out what percentage to pull/add. Have over want. IE have 0.85 lambda want 0.80 lambda = 0.85x0.80=1.062 so adding 6% will get me to my lambda I want. Also I know when I do the division if I see a 1.xxxx that means it needs fuel added. If I see 0.xx that means I need to take away. And best part is if your tuning software allows multiplication, you can type that value straight in, *1.06 for adding 6% or *0.94 for removing 6% for that cell(s) value. Or vice versa. Have 0.80 lambda, too rich, I want 0.85. 0.80/0.85=0.94 or I’m taking away 6% fuel. Greatest thing about lambda as you already know, doesn’t matter what stoich is of the fuel you’re using 1 is always stoich etc. makes it so much easier. I love using lambda instead of the typical gas scale. If for whatever reason you want to convert the lambda to AFR that’s rather simple as well. You times the lambda value you have by the stoich of your fuel. So if I’m using regular ole gasoline, I’m at 0.85 and I want to for whatever reason, know what that is afr wise, I’ll do 0.85x14.7=12.495AFR, or if I’m using Q16 with a stoich of 13.33 0.85lambda would be 11.33.
Hi Great to see and learn from your video, I just have a question I have MIVV full system exhaust, PCV and Stock airfilter on my CBR 650F I dynoed my bike to see the power output which is 81bhp saw another video where in the guy has flashed his ECU and his bike is showing 96 bhp , just want to know can I still flash my ECU from the same tuner keeping my PCV also working with same. Is it really possible to keep both
Glad you like our vids. Yes. As long as the fuel tables in the ecu are not altered, your pcv and maps will work like they do now. Please note, you will probably need additional pcv mapping after ecu derestriction.
Brock,thank you for very informative videos! Tell me please, how to tune bikes with ram air intake? Do I have to tune them richer at high rpm and how much? Thank you!

Hell yeah that suzuki is a beast and needs to have the bmw s1000rr for breakfast
Found your videos randomly. Keep up the great work. Whats the best way to go with a 2018 gsxr 1000r with a full alpha t exhaust.
Glad you like. Please contact sales@brocksperformance.com for questions on products or dynoroom@brocksperformance.com about ECU Flash specifics. We are always willing to point you in the right direction.
What did you end up going?
Hi Brock, I’ve been following your stock to brock series very closely. I’m currently working on a 2017 GSXR1000R with Bazzaz ZFi & FTecu flash.
I’ve taken a look at the throttle plate mods which is already in place for the ECU number I’m using so I’d be expecting not much power gain from a base run I did on the dyno.
As mentioned earlier, the bike is running on Bazzaz ZFi, FTecu flash (EU flash), sprint air filter, decat with SC project end can. Do you know as to why I am not able to achieve a power gain despite the above?
Stock: 168-170hp
Brock man you are amazing 😁
Hi Brock... i've been watching from the begining and starting on the 190hp, passing by the 204 and now 190 again it sounds kinda strange... however, it's not all about HP... i noticed you never mentioned anything about torque, it is because you don't find it relevant for your tune or because you simply decided to ignore it...?
@MrGuerra - we have mentioned torque as the force that accelerates the vehicle from the beginning of the series. That said, we find that it's not easy for the average person to relate to this increase. In episode 2, we made 165.73 RWHP SAE- in E7P2, we are now at 194.14 RWHP SAE (an increase of 17.5%). It's fairly easy for most to understand that we now have a MUCH faster motorcycle. If I told you that we gained 6.19 ft-lbs of torque (a 7.5% increase) over that same period - would you understand this to mean the EXACT SAME performance gain? We will get into torque multiplication, and it's benefits (or downfalls) in more detail once we get to the drag strip.
Brock Davidson Thanks ! Apreciate your atention.
Also 204 was on MR12!!!!! Not not 89 pump fuel.
Always have, and probably always will use a PC5 on top of my flash for quick adjustments at the track. Far too many tracks out there that lack a decent enough internet signal to flash the ECU successfully
Brock, have you happened to see what the top speed on the dyno with the stock sprockets on these 17+ gixxer 1000 is by chance? I can't seem to find what the gearing limited top speed is anywhere!? I want to drop a tooth in the front and I'm trying to calculate how much top speed I could potentially lose. If any.
Hi Brock, my local tuner in the UK keeps telling me to go the ecu flash route to sort out the fuelling etc, In your opinion is a Power commander the better route or should I go with the ECU remap?
Thanks Mike.
blog.brocksperformance.com/ufaqs/how-can-brocks-get-mapping-so-close/
Can you explain why @5:50 we see the map numbers jump from 16 to -5 within 250RPM? I would expect to see much less variance between numbers and see a smoother transition. Fantastic series btw love your work. I have a 2010 gsxr 750 with straight pipes (no cat), M4 and a power commander 5. I bought it with a dyno tune on it with a custom map but I am not sure if it had a custom ECM tune as well (have the printout though). - just looks odd when I see the trim numbers change so drastically.
Also, can you explain how the gsxr's have a power mode switch (A/B/C setting) affects the maps/AF ratios? - I am unclear what the power mode switch actually does. (retard timing?, change AF maps?) My spider sense tells me that if you muck with the modes it is going to affect the air fuel burn which is going to throw the map out because the map is tuned for a specific config.
Large jumps in small rpm's are required to keep the AFR correct throughout the range. This is common when a precise AFR measurement, under load, is observed. This doesn't happen in the stock ecu mapping... Which is why stock ecu mapping works so poorly. If you add a wideband sensor to your pipe and go for a ride, you will see the same results, once corrected.
@@BrockDavidson Thanks Brock! I have rebuilt many car engines from full tear downs but the whole Air fuel thing was a complete mystery to me. After seeing the first video I binged the whole series like I was watching breaking bad for the first time. I am hooked. absolutely fantastic. You are a master in your craft!

Hi Brock, I own a 2015 ktm superduke. I left the stock headers but I replaced the catalyser with a link pipe and I have the Akrapovic slip on , I saved around 10 pounds ( 7 pounds from the catalyser and 3 from the slip on ) I didn’t replace the headers because It was way cheaper to take off the cat then to buy the 2 grand full line. I also removed the stock air box and installed the Rottweiler air box ( way more air comes in ) I installed a power commander 5 and an ignition module and had it tuned on the Dyno. I do feel that the bike is more powerful but I find that when the weather is hot and humid the bike doesn’t perform as well ( not even close ) to when the weather is cooler. Do you think that installing an Auto Tune would fix that problem? Another Question: do you think that the setup of my exhaust without the full Akrapovic header was a good idea? I mean do you think that the Akrapovic headers would have increased the performance? Cause in my point of view it basically ends up being equally the same. Thanks
petelpete - headpipes are the part of the exhaust that improve horsepower - a slip-on improves the look and sound. As far as hot/humid weather - some bikes compensate for it better than others. You can create your own -5% across the board 'hot weather' map and select between it and the map you are using by installing a map selector switch: brocksperformance.com/dynojet-map-selection-switch-power-commander-v/ if you had your bike tuned by a competent tuner, you should not need an autotune unit.
New viewer and new sub! 😃
Good stuff brock. The gsxr is coming along good. Quick question: I have an 06 gsxr 1000. Would you recommend tuning with a pcV or flashing the ecu? Thanks
Both if you would like flexibility in your tuning. Flash alone if you want set and forget. Contact dynoroom@brocksperformance.com - we have a flash for your bike,
Brock Davidson
Thanks. Originally with a full titanium m4 GP exhaust with a teka box tune, produced 153rwhp and 80ft/lb torque. With your full alien head exhaust and pcv tune, produced 163rwhp and 78ft/lb torque. Just curious if flashing the ecu would produce more power than the pcv for my bike.
I just buy bike K5 1000 with almost 50000 miles on it, dont know history, bike was already dyno mapped i have dyno print. Custom mapping here cost 450$. I am just street rider, enthusiast which want just that bike run smooth. For 450$ I can buy pcv and auto tune. Can you advice pcv to go or again custom dyno tune? Do you block PAIR system?
I’m trying to wrap my head around ECU flashing vs a power commander. I have a tiger 660 and just installed a Zard full exhaust. I want to tune the bike now and debating whether to flash, install an power commander or both. What do you recommend. Also can I stick to the sock air filter or do I need to upgrade with the tune.
Thanks
This should help: blog.brocksperformance.com/faq/do-i-need-a-pcv-when-installing-a-brocks-performance-exhaust-system/
So brock I'm confused when you talk about the exhaust on the bmw and the gsxr you said you went with the alien head cuase your going drag racing but if you wanted more midrange torque you would go for the predator. I thought midrange is exactly what you want to be better for drag racing doesn't the midrange help with acceleration?
@Jock - Great question. In drag racing and land speed, the bike spends almost all of its time in the high revs and WOT. We can make simple gearing adjustments if we want more torque or more speed. Dropping 1 tooth on the countershaft has more of an effect on acceleration than we could ever build into an exhaust. In road racing, the bike spends most of it's time with the throttle partially open, especially on short courses - this is where a broader power/torque range is most benefitial.
HI Brock The FI on all Honda CBR from 2008 when started commence moving the timing forward in large increments automatically and will continue to advance untill the knock sensor detects knocking, when knocking is detected the ecu retards the timing by the last increment and then rechecks, if a knock is not detected then the timing will advance in smaller increments unit again a knock is detected. This continues untill the max timing advance is achieved and no knock is detected. This process occures each time the bike is started.
It is designed to get the best advance setting regardless of fuel used, considering this, is possible to flash a different timing map on a CBR 1000rr or flashing a Honda only involves the fueling?
@Sebastain - In the past we 'tricked' the ECU into not allowing this to exist by using a Bazzaz Z Bomb: www.bazzaz.net/index.php/z-bomb/z-bomb-cbr1000rr-08-14 - today, this can be incorporated into the ECU flash.
I'm told repeatedly to gut the air injection system in order to dyno tune. If it doesnt fool the stock ecu and o2 sensor why would it bother a dyno tuner? To me the air injection helps keep everything from exhaust valves, o2 sensors and exhaust piping cleaner and lasting longer and not carboned up.
The best tool is a motivated tuner, if he doesn't like you or just wants to get your bike done, that's it.
The O2 sensor (s) is there ONLY to measure cruising speeds to allow the bike to meet strict emissions regulations. As soon as the bike moves out of this cruising area (@7.5K+ and 20%+ Throttle)...it moves to static (no adjustment from O2 sensor) maps stored in the ECU. As soon as you make changes to your bike that require fuel remapping (aftermarket exhaust, high flow air cleaner, race fuel etc...) you will need to measure the AFR in these areas and make adjustments to the static fuel mapping (via PCV/Bazzaz/Rapidbike/ECU fuel tuner etc...). If the Pair is functional, the actual AFR is corrupted by the PAIR adding air into the exhaust port. This air is only required to increase the heat in the stock converter - in race applications using full systems, it's an unwanted/unused/undesirable nuisance to tuning. Example: actual AFR is 12-1...but PAIR valve inserted air mixing with the exhaust gasses FOOLS the tuners measuring device into reading 14-1. Common sense says the tuner will adjust the fuel down to the desired reading - let's say the tuner is shooting for a 13.2-1 AFR. If the PAIR is functioning, the actual AFR was just accidently tuned to an undesirable 11.2-1. Power is lost, emission readings are up and the bike runs like pooh and huffs black clouds of smoke, even though the tuners measuring device shows it's a perfect 13.2-1. This is why the PAIR MUST BE BLOCKED when tuning for performance. As far a "cleaner"...sure, but it comes at the expense of poor drivability, poor acceleration and decreased top speed as well as the "deceleration pops" (mini internal exhaust explosions) and excessive heat destroying your expensive aftermarket exhaust. FYI: OEM exhausts are heavy and sound like they do because they use metal internal baffles that won't fail from the additional heat required for clean air regulations. Aftermarket exhaust use thinner/lighter material as well as fiber baffles to produce more power as well as the sound performance enthusiasts desire. I hope this helps you better understand why the PAIR must be blocked in performance applications, especially when tuning.
@@BrockDavidson if someone disables the O2 sensor would that send the ecu into failsafe/limp and retard ignition all across ?
@Brock - I don't know too much about drag racing, time to peak power clearly in the GIxxer's favor, but does that mean the BMW would be catching back up at the end of track, all other things being equal?
@Getis - Our GSX-R 1000 currently tops out on the dyno at around 183 MPH (OEM tire/gearing/peak rev limit, etc) The BMW will run @195 MPH with the same set-up. It would also depend on how long your 'track" - the BMW's speed would show up in a standing mile - not in a 1/4 mile.
@Brock - There are some guys from a Ducati V4R video who refuse to believe the Suzuki makes this power. They keep giving me the business about how my dyno guy is lying to me. Oh man, I can't stop laughin at these people. As if Brock Davidson, the man himself, is going to compromise his business by lying and selling products that don't work? Dang, it's hard to understand people sometimes. I try to tell them that Suzuki is making their power by VVT, among other things, while Ducati is making it old school, by installing a high lift cam, which of course will likely shorten the engine's lifespan when comparing apples to apples. The claim is the V4R makes 199 and I said I can't justify $40K for for 4-5 more HP, just get the Gixxer with aftermarket goodies added on for under $20k. They didn't like that very much - hahahaha
@Getis we have not had the V4 on our dyno yet, but I understand they run strong. They would need to be VERY strong to pull 198 on our dyno... but who knows? We usually adjust negative attitudes with a trip to the race track... they understand better afterwards ;)
Great videos !!!! One question, I have the s1000rr. I have a Rapidbike installed. Have you ever dynoed a bike with a Rapidbike installed ??? I'm curious to know if the AFR is on point ( smooth flat line).
Not recently.
If you had to take 1 bike Brock , Gsx-R or S1000 what would it be?
For me it's the Gsx-R.
Thanks for the awesome video's by the way .👍👍

I have a power commander and a plug and play quick shifter both Dyno jet brand. Auto-tune and unplug or auto tune keep it plugged or Dyno customized map? Thanks if you reply.
Either. It can stay plugged in, it only makes changes to the map when you tell it to. If you have a good base map, you shouldn't need it...if you dont, it can help. Hope this helps you.
more videos coming ?
With the inability to get a flash for a 2021ZX10R would you suggest a rapid tune or bazazz or a pcv or is there any way to tune through the stock locked ecu
Any piggyback can help - if available and tuned properly. No tuning whatsoever to a locked ECU.
Sorry, in this video you apply table(pcv5) to Fuel maps..but table pcv5 got only 10 columns(throtle positions) ECu flesh got so much more throtle positions(columns) so how they transform
Maps average between columns when viewed as a percent. If the secondary injector percentages are the same, the map import works ok. As soon as the secondary percentage changes, the import does not work well. This is why we adjust by hand in these areas.
@Brock Davidson does this bike have a knock sensor? I went back and looked at FTECU unrestricted map and it has many small changes in the ignition timing. Im 240lb rider and I absolutely have a hard time redlining it in 6th with every mod in this series (almost) and theres many, many videos of people grabbing this bike stock and easily rev limiting this bike in 6th... easily achieving even a top speed of 301km/h 100% stock. My friend has been working on stuff for a long time and I went over a long conversation about this and he suggested because of the advanced ignition timing it could be knocking and the knock sensor limiting the engine making it hard to reach rev limit. I'm really not sure why they have advanced ignition timing in their basic unrestricted map for download... The only thing I wanted was open throttle blades and no top speed limit. That's my other question. Will it have a top speed limit of 186 if I change the stock maps manually and ecu settings myself? I don't see an option for top speed limit in the files anywhere so im not aware how they do that. I'm pretty sure the cluster is locked to 186mph also?
@william. The bike does not have a knock sensor - Per our videos, our mapping also does not include any ignition timing adjustments. FTECU should be able to help with your questions regarding changes to their maps.
