Just realize I said to set the dynamic airflow re-enable setpoint to 8k rpm. It should be set below the disable setpoint which we set to 100 rpm, set the re-nab le to something like 80 or 90 RPM. I don't know for a fact it matters but you are better off with the re-enable less than the disable.
I noticed that you always renable your oxy sensors and stft and ltft after you finish tuning is that necessary since I want to tune my car in close loop maf tune all the time do I still need to re-enable the oxy sensors which will enable the open loop again ??
Hey guys!! Y’all need to check his videos out three months ago I didn’t even know what HP tuners was I’ve always been mechanical today I’m doing my own tuning still have a lot to learn he always answers my questions and gives great feedback so if y’all want to learn your in the right place subscribe give him a thumbs up that way at least I can keep tuning!! ABT!! Later!!
A Sawatzky brought up a great point, it is a normal issue that the first cell in the High MAF table will have bad data in it unless you actually get high enough to register values in the high table. A way to fix that is to go into your high table filtering settings and use the following function to only allow data to show up that registers over the 5800 hz, to do so paste this in "[50080.50] >5800" and the bad data will go away but still allow you to log properly. It doesn't seem to be an issue on the Low MAF table but could do the same thing only switch the direction of the comparison function to "[50080.50]
It's about time someone posted a video on how to do this! Beginners struggle with this. I've done a course with the tuning school to learn this. Your information is a little different from what they teach, but theres more then one way to skin a cat. So I can't say you're wrong. But this was a good video, and seeing someone take the time to post video knowledge is much appreciated. Good job!
@@GoatRopeGarage it's good to know about adding 1% (X 1.01) across the entire curve. As we all know the LTFT tend to carry onto WOT range. That's if you nail down the zero range.

Hey brother, just want to say thank you for your videos. They helped guide the way through this process. The hardest part of this was finding a good place to tune on the street. A lot of times I pulled over to adjust the tune, I would get stared down like I was a suspicious character. It made the task a lot more daunting, but the AEM worked great. Going to keep it on until after winter to see how it handles the cold.

I have watch and then listen to all the gen4 e38 videos twice and I like to thank you I got screwed and taken for a ride by a local shop in the Miami area (West Kendall) and I had to buy a mpvi3 just to try to undo what they did I have saved my 6l80 from further damage at this point thank you so much I am not at all a computer guy what's so ever and had to have my wife set all this up just to turn on the torque management back on
Just discovered you a short time ago and been watching several videos. Good stuff, very helpful! I've got a 78 Bronco with a 2013 L92 engine and 6L80 trans. DOD delete, sloppy stage 2 cam and a little headwork, 3.5" intake tube, card MAF, K&N filter 3" custom stainless exhaust. Just started attempting tuning last week. I look forward to learning enough to get this thing running well.
Hey brother fixing to do cam upgrade my self I’m torn between 228r TSP and sloppy stage 2 I haven’t found a lot of data on the sloppy I was wondering were about your power band kicks in does it do good in the low end??
Nice man really excited to dig into your info tomorrow. I've got a 06 5.3 that's getting a DOD deleted this week with a summit 8719 cam. Going to do some idle tuning and maf tuning. Really appreciate this info. Subscribed !
Just started watching your vids and just got my hp tuners looking forward to learning this art. Great content brother thank you been wanting to get into tuning for a long time
Thankyou brother I was going to run off the first Video mines a Gen 4 2011 GMC Sierra and yes this one matches up to my platform. I was stating today so thanks for this video!! ABT
Wow just wow!! I stumbled up on this channel and loving it. I can’t seem to get my is swap running right. At start up it falls on its face and turns off. I have to hold pedal light for a min or two meanwhile ECU balances out. I can’t keep paying tunners for my issues so I’m giving it a shot thanks to the GOAT. Hp runner arrives 26th and could use any help offered by you
@@ScrubGaming97could you help walk me through adjusting a few things? I just can’t figure this out and have Katie the car due to needing a break. It’s taking atoll.
Used this today to sort out my CTSV with an LSA after my new fuel pumps changed things a bit. Theres a couple things in slightly different tabs, but I kept having big swings the other direction whenever I made changes. Turned out there’s hot fuel pressure, default, normal, low flow and high flow modes and these kept changing fuel pressure. I had to set the normal, default and hot fuel setting to match the low flow mode at 50.8psi and after that my results in the maf error chart were much more predictable.
very clear two questions I have a E38 on Impala 3,5 lt 2009 engine turbocharged....... I run only on MAF after adjusting MAF as you said how to manage boost enrichment? or generally how to enrich the map
Hey man thank you for your help but I followed everything on the video and whenever I try to get data to show up in my maf error graph it only shows cells with -100.00
We need more e78 specific content. Trying to learn how to tune is so much harder when basically having to learn gen iv and v at the same time adding on top all the turbocharger tables I feel like I’m doing 3 cars at once.
Well I guess I’m doing catch up on all this tuning stuff, I’ve built up my 08 Z06, and with no tuners even close to me , theses videos are just what I needed. If you could slow down your curser movements that be great.
Nice vid explaining the process. One thing I have seen when logging on ecm's with 2 maf tables, you need to look out for, is that for example the high freq table will populate the lowest cell even if the freq is lower than the high freq table. Same thing happens if your in high freq table and it will populate the low freq table on the last cell. Not sure if I explain myself. And I think that's why you only got data in the first cell of the high freq table in this vid.
That makes sense as to why there would be data in that lowest cell, good to know! Thanks for commenting! Make sure you're getting data in that top table beyond the first cell to verify its using live data!
Exactly. I usually like to take the 2nd cell and up and then just interpolate the cell under because usually the lowest cell takes the whole average of the low freq table
I tested adding a filtering function to not allow data when below 5800hz and it cleared up the false data in that first cell. Good catch! I pinned a post to the top of the comments explaining how to do it.
Yea I thought it could be done with filtering but I knew about the issue and I lived with it. I have learned a lot of things from your videos so I'm glad I can be of help to someone
Hey there, love the content, and its helped me out alot. With my understanding of tuning. Many 'Tuners' at shops try to make you think that tuning your car is some complicate process that requires a doctorate to understand. It does require attention to detail and understanding, but its not as scary as people make it out to be. OK, now the question, you touched on this in the video. How does making a change to the exhaust cause a car to run leaner? I only ask this because I want to get an understanding of how this effects the tune. I don't get how improving the exhaust flow would cause the metered air coming into the engine to be changed. I get that it improves performance, and helps the car run better, but I am not putting together how that change would impact how the MAF sensor calculates incoming air. I just like knowing this information because it will help me out. If you know of a good video or page that describes it, I'll take that also. thanks!
A bit puzzled on the wideband use... Is it just assumed that everyone needs an extremely expensive accurate wideband to tune? or if you just use a cheap wideband that still costs more than most cams... They are significantly less accurate than the factory narrow bands unless you are way off (out of range of the narrow band) right? Can you just use the STFT for the error percent, or did I miss something and you need to just drive around with a wire hanging out your window to the wideband until you get this sorted out?
goat rope garage I decided to try to tune my supercharged 2010 Camaro. After installing the supercharger I had it dyno tuned. Ran and drove great. Since then I added headers and cat delete and figured this would be a good point for me to try to tune it. I watched your videos but im running into issues. every time I start a log my eq err is rich along with reading from my wideband. I drove to get a log and by the time im done with a 10 minute drive to get data the same spots that were rich are now very lean same with my wideband. The engine is up to temp at each start up and commanded eq is constantly at .999. looking at the original stock tune from before I had it dyno tuned to what I started with I see a couple engine diagnostic parameters changed p0101 p0106 p0121 temps are bumped up to 256 degrees. Map high voltage test is set to disable. air flow correlation p0068 rpm is set to 8000rpm. could these be my problem when trying to do MAF tuning? Not sure what direction to go in at this point.
Love the vids and info in them. I, for the life of me, can not get my new histograms to populate. I have followed step by step but I know I'm missing something.
So, trying to do this now on an 08 TBSS. The table isn’t populating any info! 😅 am I missing something? Also, it’s lean AF without the VE table in use! 😅
Thanks for the info man I'm still new to the HPTuners. I have a 06 Saab 9-7x with a I would say a mild cam and cant get this MAF close. I''m not using a wideband at the moment waiting for my long tubes and y-pipe to get in to install it. But it just seems like I make a small adjustment to add more fuel and then the whole table goes lean.
Hey Isabelle, did you ever figure this one out? I have the same thing going on. What I done was instead of splitting up the graph to a high and a low I just cut n pasted the entire string of variables. I don't know if this is the proper work around so that is why I ask.
That is what I did too. My 09 G8 only has one MAF Cal table. I just made one graph and it seems to be working fine. I have done 2 good logs on it so far and it seems better.
So I’ve got a V2 and followed these steps to the T creating the table to generate the MAF hz graph…nothing populates when I attempt to log…PID for MAF shows accurate values for MAF but it never populates into the table…don’t have a wideband in the car but can steal it out of my TBSS if that’s the missing piece…any other reason to look into as to why it worse populate the single MAF frequency graph?
Awesome information, my car runs lean under 4K rpm, hoping to clean it up this weekend! Can I add some percentages in the MAF table to richen it up as a start point
Thanks again!! Had some beginner issues getting the wide band figured out to read lambda.. after a couple data logs, and a little interpolation my AFR is looking a lot better, (aka not pegged on 22)! Pretty awesome to use the help off a free UA-cam page and get the car safer and making more power than a *tuner* did! You sir have my full attention and appreciation!
Hey I'm very curious on why you only use half percentage instead of full percentage? I can understand that with it coming down till like really small fractional changes like to 3% trying to refine it a little bit more using half percentage but what about the ones that are pretty significant that are 810 15% Etc those are the ones that I've always understood to do full percentages on and then come back and do half the closer you get to being as perfect as you can. Thank you for your time and keep putting out great videos
It's a combination of overshooting your corrections and making smaller, easier to blend changes for when you have to fix certain areas of your map to get good calculations
Can you Make a video where you potentially upgrade an early Gen IV DELPHI Maf sensor (round style) to the later HITACHI (card style) sensor. I know there are some tuning involved with the frequency and the Idle map. Just dont know whats the best way of going about it.
Much much appreciated info from another continent!!, I pretty much got my AFR dialed in after this video, but here in the middle east weather can reach 113F, My IAT is hitting 145F, Should I relocated my MAF/IAT sensor?
Woking on tuning my 07 trailblazer ss when i stab the throttle from a dead stop it goes into reduced power mode where should i be looking to correct this issue wanting to take it to the track but not get embressed by it shutting itself down
Im sum what new to tuning (HP Tuner Pro) however my tune file does not have o2 sensor tab? so im not sure where to shut them down? (E38 2007 Yukon 5.3)also Ive set up the graph with the hi and low Maf graph like u discribed the blue block moves around the cells but no data is being logged? any help will be much appreciated thx Frank
When I did this evening read 0. I have a big Texas speed cam would you re enable ltft? My 02 readiness it’s still at the max value but the car runs very well with it like that would you leave like that?
1st off great video lots of information I'm just starting out on this I've been screwed over by shops so I'm trying to do it myself now question is do I have to Have a wide band sensor to do this modification I'm at the end of my project but low on money lol I finally got the car running and moving but just fosent run quit right did a swap from a 2014 camaro with 6l80 and the ecu to a 64 impala any help is greatly appreciated
Thank you for the great videos. My situation is a little different. I fall into the engine swap category. I have a Lexus LX450 ( Land Cruiser) with a Gen IV 5.3 and 6l80. I have been learning and tuning it for a couple years now. Your videos make the process so much easier. I decided to take a fresh look at my tune and really try to get it dialed in. Can you do something on setting base airflow and idle tuning? My engine is essentially stock ( aluminum 5.3 ,no DOD but VVT) I love the combo and would like a fresh angle on dialing in the idle using just the oxygen sensors.
Tried to do this with my LFX powered MX5, having problems trying to dial it in, I start to get good data, then half way through it seems to lean out, intake temp, coolant temp all the same, not sure what i'm doing wrong..
Question. What if a wideband is not available for installation in an optimized location? All of the cars I have tuned DONT have widebands installed at all. I use STFT or STFT+LTFT in closed loop to get the low-speed fueling right. I switch to the wideband for WOT fueling (I keep a WB with me for tuning. Tailpipe mount, unfortunately). What are your feelings on this?
Since you're doing PE it's probably a safe approach, so long as you're watching knock. WoT is when it's critical to use a WB since you're narrowband sensors can't read correctly when that rich and you should have enough exhaust flow at WOT to keep issues from studying from fresh air hitting the sensor.
In the process of doing this but notice on the wide band in upper rpm’s 4.5-5k plus it reads in the .7 but nothing on the log shows it running that rich. Any ideas?
I mean.. is that it? What do you do after you make these changes? Just trust the MAF to run the car and go out and do full throttle runs and log it to make sure you're not too lean or too rich and have 0 knock? What if for the sake of example, the car runs lean after this? what would you adjust from there? I want to learn tuning so bad I can taste it. I'm a mechanic, I've built so many cars over the years but I hate relying on a tuner to finish everything up. I also went to school for auto engineering for a little bit, so I have some knowledge, just trying to figure out how to use HP tuners. I installed an A&A kit on my ls3. V3 TI. Already pulled some timing out (trying to run 28 degrees total) so I'm safe to try and tune the fueling. Tried logging my knock sensor and shit man I don't even know if the sensor is working. had the car tuned when it was N/A so i don't know what he changed or if he turned the knock sensor off or if he was maf tuning or speed density tuning. HELP
I am a part time tuner. I only tune my own vehicles and have been listening to all of your tuning videos using HP Tuners. You are very well versed in manipulating the software which is what i was really interested in learning . It took me at least 5 years as a beginner user of EFI Live. I bought HP a few years ago but have never used it. I like the way HP addresses both MAF and VVE tuning on the Gen 4 engines but after having some success with MAFb tuning VVE is out the window. Dealing with graphic peaks and lows is not intuitive the way the tut presented it. I want to use HP. It appears that when you tune the MAF you do not reset the PE at a fixed value should I do that or not?
@@GoatRopeGarage basic tune thinking of getting a cam for it and id like the extra timing on e85 its a 350k mile 5.3 stock 4l60 4x4 did the map have ran the truck about 20 times but heat messes with my tune some days 80° others 110° but my rpm falls when i do the map tuning
I have an 07 c6 base ls2. And in my scanner it’s not giving me an options to selects hertz for the maf. Any help would be greatly appreciated. Thank you
GOAT ROPE GARAGE You are awesome!!! I have a 07 tbss and wanted to start tuning! I’m going to get the Mpvi2. Should I spend the money and get the pro version??
If I were tuning a completely stock gen 4 vehicle is MAF tuning necessary and could I just multiply the stock table by the 1.01 or .02 and see what I get on my wideband or would I still do this process to get the extra fueling? BTW I've been watching your videos like crazy and if I get tuning figured out it is 99% because of your dedication to spreading the knowledge man and I really appreciate it!
Hey so got the same car on the Dyno this week and our cylinder Airmas keeps coming down a little while the rpms are rising. For example .94 at 5000 rpm then 5300 rpm .88
great video, im just getting into tuning, when adding fuel to the air flow vs freq low do you do the same to the high side? and what does the low side effect vs the high side?
Maybe I’m not collecting properly. I ride on longer roads where I don’t have to stop use the tip up to hold gears slowly open the throttle up to wot should stop the log and not coast I dunno I make a change it just keeps getting richer. Also I don’t understand the pe part if I push to wot won’t the pe table target a richer than lambda ratio.what’s a good video for how to collect data .
I have fallowed several of your videos many outlining how to set up you channels in the scanner. They populate and move but they do not provide any data to input.
Hey Kyle, trying to force maf, got a couple questions. First I had no hi rpm enable or disable. Second under dfco all I have is spark-enable, fuel cut-disable, engine throttle con.-enable. Is all i do on this part is disable fuel cut and thats it?
Working on a 06 E40 TBSS. Injectors are out of limits so I had to use the double stoich method. So using AFR commanded / WB, WB showing 15.1 at idle and AFR Commanded is shooting for 26.64. At this point do I just need to switch to Lambda and use EQ Ratio? Using a LS7 card MAF but went from a 3.5" to a 4" intake tube in prep for the turbo air moving through it. Thanks for any feedback.
Hi I was looking to set my Editor as you have and explained, when I look at mine under Airflow then General tab, then across to Maf Calibration, I only have one field (Airflow vs Frequency) not like yours with two fields High and Low Frequency, can you explain to me why mine doesn't have these fields, maybe I have a setting in correct, my Pcm is an E67 and I don't have a wide band connected at the moment not sure if this makes a difference Cheers Glynn,
Just different ECU's, some have a single table, some have a high low and you have to build two graphs for each one, just keep the last cell in the low and first cell in the high the same value.
Greetings, You have a great channel for DIY guys and you do a great job of presenting the information, thanks for that! I have an 06 C6 ls2 Z51, 3.5k ft. alt. in West Texas. It has VR CAI and cat-less exhaust and ported intake manifold. P0171 & P0174 lean fuel codes are set. Are there tuning remedies to prevent these from being set? Regards,
So since you are using lambda for your mixture and I’ll more than likely be using air fuel will the 10 and -10 values for the graph layout still work with afr or will I have to use lambda with those numbers?
Question on tuning the LTFTs with a Wideband. How would I get the Commanded EQ and Actual EQ from the WB to make the LTFTs to 0% or as close to 0% as possible? Thanks man
So I notice when I’m idling at 725 on my mild cammed 6.0 my MAF hz reading is higher than some other peoples, about 3500+. My CAI has an insert just before the MAF that necks down the inside of the CAI tube. Should I remove this and retune? It reduces the inside of the 3” tube down closer to 2”. I noticed this when trying to troubleshoot why my truck would slowly run leaner and leaner on the WB at idle. It’s making it hard to get consistent readings to adjust my calibration with.
I’ve been all over the place but I’m starting over from scratch doing it right I wanted to him the torque tables turn them up and then go straight into MAF today would that be a good direction to move in right out of the gate?? Well after DOD of course as well.
Don't go to crazy on the torque tables. You can adjust them first but it won't hurt anything to do airflow first then come back to them. They might limit you in some of the higher cells. I'd do a conservative estimate of the added power and adjust the torque table appropriately.
I went of the torque video you did and did the over all I think I only bumped all of it up 100 and did that on each spark table equally. I’m getting my afr gauge today!!
Hey bud still getting my ducks in a row to start maff tuning cleaning my tune up first but I haven’t changed my stoich should be set to 14.7 across the board right from the factory it drops out at a 100% to 8.9? And I shouldn’t mess with the fuel pressure it should be set from factory I show 36lb-h @58psi for gen4 10-14 they have high pressure set at 53.7? Hit me back if you can thanks for everything!! ABT
Stoich will change of your have flex fuel, if not you can change it to 14.7 across the board. I'd leave the fuel stuff done unless you've changed injectors.
I’m running 93 still I know you wanted me to switch I’m always in the road and it’s not as easy to find. I know it’s out there but I’m not always in the city. Thanks a lot and when I do my timing should I go off the gen 3 videos??
I know lol I figured you would I guess all you needed was a kick!! Your welcome lol! Anyway thanks a lot always I appreciate everything you do! I missed y’all Thursday on Vacation my girl is not all about ABT she’s all about AB Her lol but I’m back at ABT later!!
First I want to say thanks for all the videos. I've watched several of them multiple times. I have a 2011 Yukon Denali that is pretty stock minus drop in filter and replaced muffler. I've just been trying to wrap my head around the whole tuning program before I start changing stuff. Where is my best area to make some gains? Thanks in advance.
i have an e78 ecu on a 2011 2500hd 6.0, my MAF tables are labeled Airflow vs. Frequency and Airflow 2 vs. Frequency. the first has values from 0.0 at 0, 19.6 at 2,100, 141.9 at 4,200 and so on... the 2nd MAF table has zeros across the table. im not sure where to proceed honestly. any suggestions?
Just realize I said to set the dynamic airflow re-enable setpoint to 8k rpm. It should be set below the disable setpoint which we set to 100 rpm, set the re-nab le to something like 80 or 90 RPM. I don't know for a fact it matters but you are better off with the re-enable less than the disable.
Glad you mentioned that because I was questioning it as you showed it but i'm in no knowledgeable realm to question the goat! lol

I've followed this maf graph setup but for some reason I cant any numbers to display in the graph?
Data for the math formula is missing. Make sure both your wideband and commanded afr or eq are being logged
@@GoatRopeGarage Do you have a video on setting up math parameters for maf tuning

Thanks for your help bro
Dude! You are Bad ass! Thank you for making these!
Thank you appreciate the info
Used this today to sort out my CTSV with an LSA after my new fuel pumps changed things a bit.
Theres a couple things in slightly different tabs, but I kept having big swings the other direction whenever I made changes. Turned out there’s hot fuel pressure, default, normal, low flow and high flow modes and these kept changing fuel pressure. I had to set the normal, default and hot fuel setting to match the low flow mode at 50.8psi and after that my results in the maf error chart were much more predictable.
very clear two questions I have a E38 on Impala 3,5 lt 2009 engine turbocharged....... I run only on MAF after adjusting MAF as you said how to manage boost enrichment? or generally how to enrich the map
Hey man thank you for your help but I followed everything on the video and whenever I try to get data to show up in my maf error graph it only shows cells with -100.00
Found out I had the sensor channel in hp tuners reading afr rather lambda did the transform and it now works like a charm!!!!
We need more e78 specific content. Trying to learn how to tune is so much harder when basically having to learn gen iv and v at the same time adding on top all the turbocharger tables I feel like I’m doing 3 cars at once.
Well I guess I’m doing catch up on all this tuning stuff, I’ve built up my 08 Z06, and with no tuners even close to me , theses videos are just what I needed.
If you could slow down your curser movements that be great.
Nice vid explaining the process. One thing I have seen when logging on ecm's with 2 maf tables, you need to look out for, is that for example the high freq table will populate the lowest cell even if the freq is lower than the high freq table. Same thing happens if your in high freq table and it will populate the low freq table on the last cell. Not sure if I explain myself. And I think that's why you only got data in the first cell of the high freq table in this vid.
That makes sense as to why there would be data in that lowest cell, good to know! Thanks for commenting! Make sure you're getting data in that top table beyond the first cell to verify its using live data!
Exactly. I usually like to take the 2nd cell and up and then just interpolate the cell under because usually the lowest cell takes the whole average of the low freq table
I tested adding a filtering function to not allow data when below 5800hz and it cleared up the false data in that first cell. Good catch! I pinned a post to the top of the comments explaining how to do it.
Yea I thought it could be done with filtering but I knew about the issue and I lived with it. I have learned a lot of things from your videos so I'm glad I can be of help to someone
Hey there, love the content, and its helped me out alot. With my understanding of tuning. Many 'Tuners' at shops try to make you think that tuning your car is some complicate process that requires a doctorate to understand. It does require attention to detail and understanding, but its not as scary as people make it out to be. OK, now the question, you touched on this in the video. How does making a change to the exhaust cause a car to run leaner? I only ask this because I want to get an understanding of how this effects the tune. I don't get how improving the exhaust flow would cause the metered air coming into the engine to be changed. I get that it improves performance, and helps the car run better, but I am not putting together how that change would impact how the MAF sensor calculates incoming air. I just like knowing this information because it will help me out. If you know of a good video or page that describes it, I'll take that also. thanks!
A bit puzzled on the wideband use... Is it just assumed that everyone needs an extremely expensive accurate wideband to tune? or if you just use a cheap wideband that still costs more than most cams... They are significantly less accurate than the factory narrow bands unless you are way off (out of range of the narrow band) right? Can you just use the STFT for the error percent, or did I miss something and you need to just drive around with a wire hanging out your window to the wideband until you get this sorted out?
Hello there i only have airflow vs frequency on my editor under Maf calibration thus i am a bit confused 😕
hey did you get help? i’m stuck too
If installing long tube headers, and deleting the cats/ o2 sensor 2 in both banks. Would there be extra steps to this process?
goat rope garage
I decided to try to tune my supercharged 2010 Camaro. After installing the supercharger I had it dyno tuned. Ran and drove great. Since then I added headers and cat delete and figured this would be a good point for me to try to tune it. I watched your videos but im running into issues. every time I start a log my eq err is rich along with reading from my wideband. I drove to get a log and by the time im done with a 10 minute drive to get data the same spots that were rich are now very lean same with my wideband. The engine is up to temp at each start up and commanded eq is constantly at .999. looking at the original stock tune from before I had it dyno tuned to what I started with I see a couple engine diagnostic parameters changed p0101 p0106 p0121 temps are bumped up to 256 degrees. Map high voltage test is set to disable. air flow correlation p0068 rpm is set to 8000rpm. could these be my problem when trying to do MAF tuning? Not sure what direction to go in at this point.
You should probably disable the e85 sensor as well? Mines whack at 24% with max 10% ethanol gas
thank you
Love the vids and info in them. I, for the life of me, can not get my new histograms to populate. I have followed step by step but I know I'm missing something.
So, trying to do this now on an 08 TBSS. The table isn’t populating any info! 😅 am I missing something? Also, it’s lean AF without the VE table in use! 😅
working on 02 z71 5.3 bone stock besides muffler,keep showing knock it alot of cells mainly same cells do i need a wideband to tune maf better?
Thanks for the info man I'm still new to the HPTuners. I have a 06 Saab 9-7x with a I would say a mild cam and cant get this MAF close. I''m not using a wideband at the moment waiting for my long tubes and y-pipe to get in to install it. But it just seems like I make a small adjustment to add more fuel and then the whole table goes lean.
I have a Gen 4 E38 PCM with a single MAF Calibration (Airflow vs. Frequency). Can you show how to tune a MAF with this set up?
Hey Isabelle, did you ever figure this one out? I have the same thing going on. What I done was instead of splitting up the graph to a high and a low I just cut n pasted the entire string of variables. I don't know if this is the proper work around so that is why I ask.
That is what I did too. My 09 G8 only has one MAF Cal table. I just made one graph and it seems to be working fine. I have done 2 good logs on it so far and it seems better.
Dude thank you so much. My car is way off and I don't have the money to have someone f it up more lol. If you know what I mean.
VCM Editor not matching on 2012 GMC sierra 6.0LS 2 mis-alignments. Fuel -> Oxygen Sensor -> Monitoring -> O2 Readiness ETC (Not Found) also, Fuel ->CutOff, DFCO -> Enable ECT is a graph with multiple temp ranges. Running VCM Editor 5.0.4 Good video

GoatRope! could you make a video hooking up a aem30--0300 and using hp tuners to tune maf. i cant get mt eq or afr to read on scanner
So I’ve got a V2 and followed these steps to the T creating the table to generate the MAF hz graph…nothing populates when I attempt to log…PID for MAF shows accurate values for MAF but it never populates into the table…don’t have a wideband in the car but can steal it out of my TBSS if that’s the missing piece…any other reason to look into as to why it worse populate the single MAF frequency graph?
Yep, need the wideband
@@GoatRopeGarage 10-4 I’ll steal the AEM outta the tbss…Ty for taking the time to reply sir 🤙🏽
I could not get my new graph to populate on I did everything you said to do.
Awesome information, my car runs lean under 4K rpm, hoping to clean it up this weekend! Can I add some percentages in the MAF table to richen it up as a start point
Yep!
Thanks again!! Had some beginner issues getting the wide band figured out to read lambda.. after a couple data logs, and a little interpolation my AFR is looking a lot better, (aka not pegged on 22)!
Pretty awesome to use the help off a free UA-cam page and get the car safer and making more power than a *tuner* did!
You sir have my full attention and appreciation!
Hey I'm very curious on why you only use half percentage instead of full percentage? I can understand that with it coming down till like really small fractional changes like to 3% trying to refine it a little bit more using half percentage but what about the ones that are pretty significant that are 810 15% Etc those are the ones that I've always understood to do full percentages on and then come back and do half the closer you get to being as perfect as you can. Thank you for your time and keep putting out great videos
It's a combination of overshooting your corrections and making smaller, easier to blend changes for when you have to fix certain areas of your map to get good calculations
@@GoatRopeGarage thanks brother I appreciate the clarification and response. God bless you brother
do you do any tune review for a charge, my local tunner has got it pretty close but I think that you can find more
Can you Make a video where you potentially upgrade an early Gen IV DELPHI Maf sensor (round style) to the later HITACHI (card style) sensor. I know there are some tuning involved with the frequency and the Idle map. Just dont know whats the best way of going about it.
Much much appreciated info from another continent!!, I pretty much got my AFR dialed in after this video, but here in the middle east weather can reach 113F, My IAT is hitting 145F, Should I relocated my MAF/IAT sensor?
Probably more dependent on where your intake is pulling air from
Woking on tuning my 07 trailblazer ss when i stab the throttle from a dead stop it goes into reduced power mode where should i be looking to correct this issue wanting to take it to the track but not get embressed by it shutting itself down
Im sum what new to tuning (HP Tuner Pro) however my tune file does not have o2 sensor tab? so im not sure where to shut them down?

thx Frank
Frank, look under the closed loop tab then. If it's not filling in on either then your error parameter isn't working right. Do you have a wideband?
@@GoatRopeGarage yes
When I did this evening read 0. I have a big Texas speed cam would you re enable ltft?
My 02 readiness it’s still at the max value but the car runs very well with it like that would you leave like that?
1st off great video lots of information I'm just starting out on this I've been screwed over by shops so I'm trying to do it myself now question is do I have to Have a wide band sensor to do this modification I'm at the end of my project but low on money lol I finally got the car running and moving but just fosent run quit right did a swap from a 2014 camaro with 6l80 and the ecu to a 64 impala any help is greatly appreciated
Thank you for the great videos. My situation is a little different. I fall into the engine swap category. I have a Lexus LX450 ( Land Cruiser) with a Gen IV 5.3 and 6l80. I have been learning and tuning it for a couple years now. Your videos make the process so much easier. I decided to take a fresh look at my tune and really try to get it dialed in. Can you do something on setting base airflow and idle tuning? My engine is essentially stock ( aluminum 5.3 ,no DOD but VVT) I love the combo and would like a fresh angle on dialing in the idle using just the oxygen sensors.
Yeah, going to be touching on the very soon
@@GoatRopeGarage sweet. I'll be looking forward to it
Have you ever tuned a e78? Kinda struggling on tuning it.
Hey how come my graph will not record any data with the maf lo and maf hi. I set it up the way you said but when I log it i don't get any data?
my maf hi an lo are on the grafh with a red box around them but they don't read, how do I fix that I appereciate all the help boss.
Your missing an input parameter, check that you have mass airflow sensor, commanded eq or afr and a wideband that reads the same units
When I set up for maf tuning I get the maf numbers really close at operating temps then at the next cold start it’s is 30% lean at start up????
Tried to do this with my LFX powered MX5, having problems trying to dial it in, I start to get good data, then half way through it seems to lean out, intake temp, coolant temp all the same, not sure what i'm doing wrong..
Question. What if a wideband is not available for installation in an optimized location? All of the cars I have tuned DONT have widebands installed at all. I use STFT or STFT+LTFT in closed loop to get the low-speed fueling right. I switch to the wideband for WOT fueling (I keep a WB with me for tuning. Tailpipe mount, unfortunately). What are your feelings on this?
Since you're doing PE it's probably a safe approach, so long as you're watching knock. WoT is when it's critical to use a WB since you're narrowband sensors can't read correctly when that rich and you should have enough exhaust flow at WOT to keep issues from studying from fresh air hitting the sensor.
In the process of doing this but notice on the wide band in upper rpm’s 4.5-5k plus it reads in the .7 but nothing on the log shows it running that rich. Any ideas?
Bob Ross is crying in heaven 😂😂😂 "Money Green and Angry Red" 😂😂😂
I mean.. is that it? What do you do after you make these changes? Just trust the MAF to run the car and go out and do full throttle runs and log it to make sure you're not too lean or too rich and have 0 knock? What if for the sake of example, the car runs lean after this? what would you adjust from there?
I want to learn tuning so bad I can taste it. I'm a mechanic, I've built so many cars over the years but I hate relying on a tuner to finish everything up. I also went to school for auto engineering for a little bit, so I have some knowledge, just trying to figure out how to use HP tuners. I installed an A&A kit on my ls3. V3 TI. Already pulled some timing out (trying to run 28 degrees total) so I'm safe to try and tune the fueling. Tried logging my knock sensor and shit man I don't even know if the sensor is working. had the car tuned when it was N/A so i don't know what he changed or if he turned the knock sensor off or if he was maf tuning or speed density tuning. HELP

I am a part time tuner. I only tune my own vehicles and have been listening to all of your tuning videos using HP Tuners. You are very well versed in manipulating the software which is what i was really interested in learning . It took me at least 5 years as a beginner user of EFI Live. I bought HP a few years ago but have never used it. I like the way HP addresses both MAF and VVE tuning on the Gen 4 engines but after having some success with MAFb tuning VVE is out the window. Dealing with graphic peaks and lows is not intuitive the way the tut presented it. I want to use HP. It appears that when you tune the MAF you do not reset the PE at a fixed value should I do that or not?

GOAT ROPE GARAGE You are awesome!!! I have a 07 tbss and wanted to start tuning! I’m going to get the Mpvi2. Should I spend the money and get the pro version??
Not yet
Noticed you forgot to populate the horizontal axis for airflow in g/sec.
I found out by running a read and had no data.
If I were tuning a completely stock gen 4 vehicle is MAF tuning necessary and could I just multiply the stock table by the 1.01 or .02 and see what I get on my wideband or would I still do this process to get the extra fueling? BTW I've been watching your videos like crazy and if I get tuning figured out it is 99% because of your dedication to spreading the knowledge man and I really appreciate it!
Hey so got the same car on the Dyno this week and our cylinder Airmas keeps coming down a little while the rpms are rising. For example .94 at 5000 rpm then 5300 rpm .88
3:23 SD Disable
4:09 CL Disable
5:17 DFCO
great video, im just getting into tuning, when adding fuel to the air flow vs freq low do you do the same to the high side? and what does the low side effect vs the high side?
If my 06 z06 doesn't have a wide band what is the best way to tune it? It is just all stock so not sure getting a wideband is worth it.
If you're all stock you'll get the most benefit from some some timing and dialing back some torque management. Your airflow should be good.
I have a 2010 Camaro with the E38 and the tables are nothing like the ones you have there!!!
Maybe I’m not collecting properly. I ride on longer roads where I don’t have to stop use the tip up to hold gears slowly open the throttle up to wot should stop the log and not coast I dunno I make a change it just keeps getting richer. Also I don’t understand the pe part if I push to wot won’t the pe table target a richer than lambda ratio.what’s a good video for how to collect data .
I have fallowed several of your videos many outlining how to set up you channels in the scanner. They populate and move but they do not provide any data to input.
Hey Kyle, trying to force maf, got a couple questions. First I had no hi rpm enable or disable. Second under dfco all I have is spark-enable, fuel cut-disable, engine throttle con.-enable. Is all i do on this part is disable fuel cut and thats it?
I have the same thing with mine. Did you find any resolution?
Got to edit (beside file), go down to view, under view select advanced, it will prompt you to restart the hp tuners

@@kennethreed5676 that's exactly where I was at haha. "I guess it's reasonable that a 2010 camaro ss would be a little different from a 2009 zO6."
I've got everything setup and did the wash, rinse and repeat. But it's showing afr on WB 15.0 to 17.0+. How do I richen this?
Do you have to have the wide band just to tune the MAF? Is it use for the histogram?
Working on a 06 E40 TBSS. Injectors are out of limits so I had to use the double stoich method. So using AFR commanded / WB, WB showing 15.1 at idle and AFR Commanded is shooting for 26.64. At this point do I just need to switch to Lambda and use EQ Ratio? Using a LS7 card MAF but went from a 3.5" to a 4" intake tube in prep for the turbo air moving through it.
Thanks for any feedback.
Hi I was looking to set my Editor as you have and explained, when I look at mine under Airflow then General tab, then across to Maf Calibration, I only have one field (Airflow vs Frequency) not like yours with two fields High and Low Frequency, can you explain to me why mine doesn't have these fields, maybe I have a setting in correct, my Pcm is an E67 and I don't have a wide band connected at the moment not sure if this makes a difference Cheers Glynn,
Just different ECU's, some have a single table, some have a high low and you have to build two graphs for each one, just keep the last cell in the low and first cell in the high the same value.
Greetings, You have a great channel for DIY guys and you do a great job of presenting the information, thanks for that! I have an 06 C6 ls2 Z51, 3.5k ft. alt. in West Texas. It has VR CAI and cat-less exhaust and ported intake manifold. P0171 & P0174 lean fuel codes are set. Are there tuning remedies to prevent these from being set? Regards,
IF I DONT HAVE WIDEBAND, CAN I DO THE SAME WITH LTFT+STFT ERR?
So since you are using lambda for your mixture and I’ll more than likely be using air fuel will the 10 and -10 values for the graph layout still work with afr or will I have to use lambda with those numbers?
Question on tuning the LTFTs with a Wideband. How would I get the Commanded EQ and Actual EQ from the WB to make the LTFTs to 0% or as close to 0% as possible? Thanks man
So I notice when I’m idling at 725 on my mild cammed 6.0 my MAF hz reading is higher than some other peoples, about 3500+. My CAI has an insert just before the MAF that necks down the inside of the CAI tube. Should I remove this and retune? It reduces the inside of the 3” tube down closer to 2”.
I noticed this when trying to troubleshoot why my truck would slowly run leaner and leaner on the WB at idle. It’s making it hard to get consistent readings to adjust my calibration with.
My guess is they do that to try and keep it from needing a tune so I would ditch it and see if it tunes easier without it
I’ve been all over the place but I’m starting over from scratch doing it right I wanted to him the torque tables turn them up and then go straight into MAF today would that be a good direction to move in right out of the gate?? Well after DOD of course as well.
Don't go to crazy on the torque tables. You can adjust them first but it won't hurt anything to do airflow first then come back to them. They might limit you in some of the higher cells. I'd do a conservative estimate of the added power and adjust the torque table appropriately.
I went of the torque video you did and did the over all I think I only bumped all of it up 100 and did that on each spark table equally. I’m getting my afr gauge today!!
I have an innovate lc2 wideban but the math doesnt seem to recognize it for the math eq err, how do i get that to work?
Transform the input, that is what causes the scanner to see it. Right click, transform, you’ll figure out the rest!
Hey bud still getting my ducks in a row to start maff tuning cleaning my tune up first but I haven’t changed my stoich should be set to 14.7 across the board right from the factory it drops out at a 100% to 8.9? And I shouldn’t mess with the fuel pressure it should be set from factory I show 36lb-h @58psi for gen4 10-14 they have high pressure set at 53.7? Hit me back if you can thanks for everything!! ABT
Stoich will change of your have flex fuel, if not you can change it to 14.7 across the board. I'd leave the fuel stuff done unless you've changed injectors.

I've just been trying to wrap my head around the whole tuning program before I start changing stuff. Where is my best area to make some gains? Thanks in advance.
Dialing back some TM, bumping spark and leaning out your PE. A good air flow tune never hurts either.
