Yes! Finally! I’ll be looking forward to watching this and taking notes when I finish work this arvo!
I swear you are reading my mind!.. It seems like when ever I get to a point where I have a question about something, you make a video around it! Great content.. keep it up! You've been a huge help for me.
I’ve always subscribed to the idea of “just because you CAN change something, doesn’t mean you should.”
Thank you for all the help. Keep the videos coming!
That high spark advance when letting off the gas is exactly what you were saying. It burns off unused fuel more efficiently, so unburned gas isn't being dumped into your exhaust.
I wish the guys here in Maryland driving around Infinitys with the exhaust chopped off would add this. I can't get on the highway without hearing POP POP POP POP POP
Right on time brother Thank you!! ABT!!
Right on point as usual 30% more to the airflow final min is exactly what I added to my tune to fix the coast down surge I had BTR stg4 Truck cam ! No one goes into the detail like Kyle Thanks again Tony V
Another good vid , thanks Kyle
another great video kyle,this helped me a bunch thank you!!
Awesome video man
This is EXACTLY what I needed. I am just changing the cam in my 2009 Corvette. Also I am adding long tube headers. I have been looking for an instructional video with details and not generalities. I plan on taking the better to a professional tuner but I sure want it to start and idle.
Man every time I search something for tuning, your video comes up. So I appreciate all the vids is what I'm trying to say bud!
Thanks for watching man, just trying to help people out who want to learn!
@@GoatRopeGarage You bet! I've been helping MotionAutoTV build a LS ranger and your videos have really helped to get it running right
Giving me great insight into runing my gen3 auto Wide duration/ narrow lc crow camshaft (1528 custom grind) :)
Cool man thank you iv done most of what you stated to start off I’m trying to fine tune mine in which my cam has a 110 lsa I should have went higher it would have made this part of tuning a lot Easier but I will be following this definitely and can’t wait for the more in depth idle video
Yeah, that is a pretty big overlap, bet it sounds real nasty!
thank you so much i learn something new today
Thanks for watching!
Great info
Nintendo games and Indiana Joes in back ground means this guy is awesome
it would be really cool if you could make a video showing how to tune the base idle airflow, using the desired airflow and short term idle trims (or whatever they are called). your videos have helped me immensely..... thanks for all the help
Thanks for the video. BTW finally got the LS swap running a couple of week ago
Sweet! Glad to hear it!
I would love to see a tune demo on how to dial in startup and idle on a 4th gen. This really helped me get me running but I'd like to go to the next step and see what to log, what to look for, and where to do corrections for the prefect idle no matter what mods are done.
Thanks
Love your in depth videos brotha would you have some guidance towards running E85 in a fbody cammed camaro as far as what brand injectors and fuel pump
great job Sir!! you the man!! thanks for the help brother
You da best!
Started doing this about 20 years ago on OBD1 cars, and one huge suggestion (especially for noobies) is to have a lined notepad sitting there. Jot down the version of tune you’re working on and WRITE DOWN what you changed! Everything. It’s great to think you’ll remember… trust me, you won’t.
When you go out for a drive and notice “something” feels gimpy, you can just flip back version after version and see what made things better or worse.
I do the same thing in notepad 😆
Keep the knowledge flow this way bud! Love it! Any way to get a base idea on large cams mathematically, for spark to be changed on gen 3
Start at 15 degrees down low, just work your way up seeing what it likes
Hey man, what would I look for if my car does when I rev it up then it does, also sometimes when I come to a stop it will surge or hunt as it downshifts to 1st
Finally. Thanks buddy looking forward to the cam tuning videos. It would be nice if you could actually get a vehicle with a cam install and actually tune it from start to finish for us. Im sure there is some people that would be willing to take a free or reduced idle tune just so you can have some hands on content.
UniX I agree, I learn better watching it being done rather than just being explained
It's a "top secret" thing, if he explain everything, how he will be able to make his business? So frustrating.
Nothing is top secret here, I tell you everything I can
@@GoatRopeGarage ...can I use HP Tuners on a 2004 Hemi Ram, if I change the cam to adjust the idle speed??? I was told the factory computer won't allow for that adjustment
Do I need any type of tune when I upgrade from a stock cam to an RV cam?
question on the gen 4. what pid do you monitor to see if your base airflow is accurate? will the tps sensor go up if its not accurate? I'm use to the old school iac motor, and cranking open the throttle body to keep that in check.
Is there anything more to adjusting idle speed for air conditioning command on an ls1 Camaro?
I have learned something from every single video. Thanx man. Any alpha n videos coming
I honestly don't know any platforms using Alpha N.
@@GoatRopeGarage my 2005 chevy classic uses it. 2.2 ecotec. I'm just gonna see if I can do anything with it lol
@@brandonpylant9349 And it had alpha n? Interesting... Might have to look into it. It's very straight forward in terms of fuel control.
If I knew how I would send you the tune its just a stock vehicle
When you X 1.3 the idle airflow table, will it lean it out a little? Its running a little rich. Thank you as always, Mike in DFW
Super new to tuning, paid a shop to base tune my truck and I'd like to attempt to dial it in myself. Any tips on getting rid of deceleration surge with a cammed 5.3? Nothing crazy, stage 2, .524/.523, I have yet to install a stall converter. Some say a converter will fix my problem others say it's in the tune. Any advice would be appreciated!
I have a 05 5.3 GXP with dod issues I'm going to pull the engine and delete the dod including blocking off the oil towers I think I'm going to install the ss1 camshaft in it so I don't have to change converter or valve springs it's just going to be a daily driver my question is can the idle / injector timing be altered to give a chop sound at idle thank you
Also could i use maxicom for other mods like air fuel and idle?
I have a gen3 5.3 with a manual nv3500 truck Norris cam and springs what sections should I change because I’m having an issue when I stop or turn the engine dies
I have a 2004 Corvette auto, just wanted to know if you know any basic settings that I can do that will make it sound a little more aggressive using my HP tuners before I get a cam install
What does Cammy Idle through tuning does? I didn't change any cams but my tuner managed to make my car sounds like I had a racing cams.
My car has a stage 3 cam and if I run it up to redline and push the clutch in and don’t shift the idle hangs at about 5800 what needs to be adjusted to fix that. I swapped throttle bodies to see it my throttle body was the issue and that one did the same thing. If I shift normal idle never hangs. Car is a 2018 camaro ss 1le gen 5 motor with a whipple
I had a custom ground RV cam from a shop for my 6.0... never hit maximum vacuum. Built engine to optimize part throttle power. It kept climbing as I increased advance. Took it all the way to 36 degrees and gave up.
Really would love to get a video that talks about idle tuning on the GEN IV. This guide gets you running, but leaves you stranded for polishing up the idle once everything else in dialed in a little bit. My car runs great now when out driving. However, there are no decent idle tuning/polishing guides for the Gen IV. So how do we get our idle perfect?
I’m by no means a tuner, but I do know the computer comes set at 14.68 afr commanded which really limits you. So the question is, how do you bypass that? I wish I knew
Not sure you will get back with me on this but why did you only adjust the in gear with ac on or off and not the table with park/neutral? I’m extremely new to tuning.
So i am looking at logging desired idle airflow but when searching for it in my scanner it doesn’t show up. Any idea as to what I’m overlooking? Im planning on doing some mods to my 12 sierra 6.2 l9h (cam headers) and wanted to get the base stuff down first. Thanks
Sorry this is off topic. I purchased the same air fuel gauge as you. Does it fit with my two 02 sensors giving me 3 of them? Thanks man!!
The advanced timing on decel to prevent exhaust popping that could destroy a catalytic converter.
Easy way to avoid this is removal of catalytic converters, I live in an emissions compliant location so once a year I have to bolt my cats back in and throw in my “CAT” tune that is rich enough to run safely at 55mph but still passes the smog test. For everyday driving the cats are removed and replaced with fakes from eBay (California will perform visual spot inspections). I’m moving back home to PA to A. Be able to enjoy my vehicle without the hassle. &

@@limabravo6065 ,,
@@limabravo6065 I don't think Darkhalf is saying how to circumvent this, I think he is giving you the reason the factory has a high advance strategy for the table at higher rpm's decel.
Ya I was helping someone with some other issues misfires I think there must be I don't know some leaking valves or something it seems to have spark fine and I replaced all the injectors for them and they said it runs good while driving they said it has more power than this other suburban that is the same years and stuff but they payed me to raise the idle and I told them there is some underlying issue but it would die in drive and almost die when the AC kicked on I got it idling alright now but it seems to come to limits on air flow that it would not let it open the throttle body enough till I got enough of the right stuff changed
Got a 2010 Camaro 6.2 ls3 mild cam when it cranks the rpm surges bad and if I add timing to the idle it surges worse it’s driving me crazy!!! What can I do to help the surging
I dont see those advanced features even after I changed it from base. I have a mpvi3! Would anyone know why?
04 Pontiac GTO T56 manual trans LS1 5.7 gen 3 now I'm going to order HP tuners Pro 2 I know they've got an n gauge handheld Bluetooth via tuning but what do I want for a wide-band oxygen sensor and gauge

I did a stage 1 cam 4v engine stays at 1600 RPM you think i need get a tune 4 idle
Got a question i just recently did a 5.3 swap on my 2012 silverado and i got it to idle in park and neutral but when in drive it dies out after trying to fix its self any ideas?
I’m stuck on setting up the graph for idle airflow on 4th gen
For cam and heads exhaust stuff no power adders do I need pro? Do I need a wideband thing I'm a newb and getting started
I have a 2004 C5 Corvette automatic with a 228 235 cam and a 113+4lsa. It chops hard in park or neutral with the AC off but as soon as I turn the AC on the idle smooths out a lot is there a way to fix this
Nice video man! Love learning from you.
Cc. The audio isn’t synced with the video. :)))
Do you still plan on doing the gen specific idle tuning videos ?
If my big cam is 272 what best idle rpm?
Freaking Kyle at Goat Rope Garage, BEST tuning TEACHER I have ever seen. If you don't learn anything watching his videos, there is no hope for you!
How about a Gen IV idle tuning vid? Or is there one you put out already?
Thanks, Jay! Probably need to do one soon!
Goat Rope Garage That would be great, looking forward to it.👍🏻
I'm having an issue that I could use an opinion on. 2000 Silverado, 5.3, 224/224 cam, tbss intake. Revs and idles fine but tries to die after the rev.
Drop a line when you get a e78 torque table based scenario. I can send you mine. Haha
Honestly so confused 😂 I’m building a twin turbo 2004 4.8 ls. Trying to run a speed density tune to delete the mass. I have relocated the IT sensor to the intake. I have a stage 2 turbo cam from comp cams. I having a hard time getting it to run and idle with the cam without the mass. I can get the truck to start if I hold the throttle but runs rough. Any help would be very helpful. Maybe I could send you a log file.
So to be able to tune idle without chasing your tail you need your fueling correct (ve) and whenever you add a cam the fueling module (ve)will probably be off how can I dial it in if I can't even start the vehicle which means I need to tune idle first right?gen 4 specific
C7 corvette Lt1 cammed and tuned. Runs great and idles around 880 but 1 thing is coming off throttle from a roll the idle will drop to around 300 and shoot back up to 880 benchmark I have it set at? Any idea why it falls so low. Great tuning tips on the channel👍
Same issue on 6.0 truck swap with cam
So rv cam is in gen 3 5.3 t engine, had dyno tuned w hp tuner. but still at times setting p0300 on hot or cold starts. Also does in gear at idle intermediatly. I've sync crank/cam.
I haven't had mine dyno tuned yet but I understand where you're coming from on the code p0300 mine does the same thing after I installed a new cam
Is timing what give the idle a crisp LS7 like sound at idle? I have a 6.0 L with flat tops heads and MS3 on a C5, I want the crisp idle sound.
Hiw to make the came chop - chop in ls1 pcm
Please what the meaning of:
Enable VSS
Disable VSS
Max VSS
?
Thanks a lot
Great info, and well presented as always. When you do the Gen 3 specific stuff you should point out that too big of a number in the colder part of the base airflow table can cause problems and that doing the IAC count adjustment procedure to open up the throttle plate a bit will help reduce the desired airflow number and let you get away with running a smaller number in your idle airflow table. And geez that Gen 5 torque based stuff looks like a whole different world to me, looks quite a bit more complicated than the Gen 3 stuff. I haven't even worked on a Gen 4 yet never mind a Gen 5.
actually the gen 3 is the more complicated idle setup just because of the way it works... gen iv is easy and so is gen V. a lot of OS optimization is needed to make the gen III stuff actually work rather well.. .although not entirely needed.
highlanderc good to know, I haven’t tried tuning on anything other than a Gen 3
Gen III isn't all that bad, if rather tune airflow based idle then torque.
@@GoatRopeGarage I need help!!! Lol
I have tried maf tuning and VVE tuning... if I get the timing to 16 degrees idling my ls3 starts surging terrible!!! I mean bad have you ever seen that before?
Hey so i have a 6th gen 2018 Camaro ss... Spark adaptive idle table is not showing at all... Is this something common... under Engine > Spark > Advance > (No adaptive idle table found) No overspeed or underspeed ....... im trying to do a Ghost cam tune for my car [Headers-CAI-E85]
Would you want to get the IAC counts dialed in before you start working on the Idle desired/actual airflow table? My Iac counts are maxed on my new build and I am trying to make sense of everything and work on things in the proper order.
Yeah, try and get them within reason, as you add or remove fuel you will probably have to go back and adjust them
If someone who has knowledge on the genV engines please message me. I’ve got a tsp stage 2 cam in my 14 Silverado. Idle is around 675-700. I ordered the hp 2 kit with 2 credits and I’m wanting to know if I can tune the truck even though it’s been tuned already. Thanks
Going to get that hat , I collect hats
Great info kyle! Thought about doing that EOIT vid for cammed Gen4 yet? 😉
Lol.. good luck
Hey bud, no reason to delete your comments, if your disagree with something just say it, were here to talk about tuning, no one here taking down to anyone else, I'm sure you're used to that else where but we're a family here that wants to learn about tuning. EOIT isn't rocket science, you just need to understand what your valve train is doing at what angle.
@@GoatRopeGarage anyway you could email me I have some questions about tuning I'd like to run by ya
if im going from an auto setup to the manual setup, would just setting all of rolling idle to around 800-850 be sufficient?
Yep, just flat line out anything that's auto trans based to your ideal setpoint.
After everything is dialed in properly with a larger cam 216-220 LSA114 what about disabling LTFT ? Think the overlap is causing issues with my MAF readings at lower RPMs and it seems much happier when I turn them off.
Be nice to see a video directed strictly at gen 3 large cam tuning tricks and tips.
Thanks
Keep up the good work
See if you can bump LTFT to come on higher than idle so you can still use it
@@GoatRopeGarage Your the man !
Raised the map LTFT idle map boundary up from 37 to 42 kpa.
Idle is much more stable now.
Building an ly6 with a truck norris cam..... not tooooo agressive. Lots of people doing the TN cam.... it be a cool first start tune vid
I have 2013 gmc 2500hd 6.0 the ecu is e78. There are many things I can't adjust it.
There will be a Gen 4 specific series soon
Maybe you can touch on deleting rear 02 sensors for headers/cat delete in a video ? Or did you already and I missed it ? Seems like such a common thing header install bam CEL!
Good idea
Good evening , my name is Chris and I I own a 1988 c4 corvette . I done an LS swap 4.8 gen 3 with. Btr stage 4 cam , sheet metal intake and 6.0 injectors . I’ve got the car starting but it does upon any gas being put at it. I have a hp tuner an a tuning guide . I’ve been reading it but I’m so confused . Anyone that can help me out in any way I would greatly appreciate it. I don’t have the money to have it tuned professionally at the moment
I need help how do i fix my 05 envoy 02 sensors after i cut my exhaust off right before the cat and straight piped to a flow master 110 muffler that just has a resonating tip that dumps right before rear axle. Can i have this tune fixed so my engine light will go away and possibly get rid of the rough idle or can i do this myself by using the maxicom tool ?
Im completely green to tuning btw but mechanically familiar
Can idle tuning be done first to get it to run with a big cam then go from there?
Yep, probably going to need to do it that way on a big cam anyhow.
Hey man i know this is an old video. Ive learned what i know from your videos. I had someone show me that you can change the idle adaptive spark control under spark, advanced. Basically you take the overspeed and underspeed settings and making them +/- 20 degrees to get the cam to idle choppier. This goes backwards from tuning. But who doesnt want it to chop a little at the red lights🤷. Is this bad. How would it affect the tune or engines performance/durability. Could you shed some advise on this please. Thank you!
Perfectly fine for a choppy tune, shouldn't hurt anything but if you take it too far it may cause stalls coming off throttle and stumbles getting on throttle, just have to find a happy median.
Thank you. The source that told me was kinda sketchy so i wanted to verify it.
I have a question on a gen 3 04 Tahoe you said on the rolling idle there should be somthing but there is only 0 on stock tune. Just curious if I should raise those to 800? Or leave them 0??
Only adjust if it’s hanging out dipping
Hey man does my wide band need to be linked to my scanner? I did everything on here except my wb isn’t linked with my scanner,but my maf error low and high tables aren’t recording anything there’s a thin red outline around the boxes by the small graph boxes by the words, just a little goofed up on this haha
Yeah, those are based on the wideband versus the commanded fuel trim
I spent to much on tuning the last few cars. I need to figure it out for my LT4. Tuners are getting too much money for their cookie cutter tunes.
Agree and Hptuners is the one product that doesn't lock the vehicle owner out of tuning functionality trying to monoploize tuning shops.
Totally agree. I dove into this about 12 years ago and I’m still learning, of course. Spent a lot of money on literature and dvds to learn everything. Specifically from a GM calibrator that was good, I won’t mention. But the first time you plug up tuners into the car and make a couple changes, all of those expenses just paid for themselves. -my take on it. We would spend 1200 for a tune now typically. I spent 350 back in the day but that was a stock with long tubes 2000 camaro.
You can still lock a ECU with HPT so nobody else can mess with it or copy it. Just depends if the tuner locks it. Usually good tuners won't. But some that have something to hide usually do or if they're just a dick.
@@tylerrobertst-rob1731 you can ground a pin on the pcm to bypass their lock.
I nearly bought the preset tuners type. Came down to wire. N because I added a cam I bought an hptuner. If it had been any other type of upgrades like bolt ons. My choice would of been Alot different.
I'm trying to tune my cammed Silverado using your method, but when I pull up the "Idle" category, the only thing that shows up for me to select is "Base", under "Base Point". Do you have any advice, or any thoughts on why nothing else is showing up?
In basic mode, need to switch to advanced mode.
Will adjusting idle underspeed/overspeed Error help the idle not fall then stall, when coasting to a stop? Could you use some advice on fine tuning this maybe video to show Gen 4 ecm, I put 102 on my ls3 and my idle goes up and down when coasting to a stop
Check the throttle follower as that is what is trying to adjust your TB when coming down to idle from a cruise
@@GoatRopeGarage I actually enabled my adaptive to active right away so anything below 300kmh..lol it worked
@@GoatRopeGarage I'll check that too

Hey ...my question is I have a gen 3 5.3 with a agressive cam. At idle my kpas are at 85 to 90. Does adding more timing lower it
How much timing are you running at idle, might try dialing your idle airflow back a bit

I am having cold start issues on a 99 camaro. Car fires right up but won't idle for the first 20 seconds then idles perfect
Josh, there is probably a separate crank table that is just for the first minute, it most likely needs adjusted.
I've seen this problem before, in my case car had aftermarket injectors, and injector voltage vs MAP offset table needed to be adjusted for the injectors
Hello,
I'm watching your channel a few weeks and I think You are the one that can help me with my 2000 firebird with corvette c5 engine swap + cam swap to highlift hotcam with 218/227 .600 .600 LSA 114+5 ICL 109 specs. I'm struggeling with the coldstartup and can't find the problem, anything I try seems to be wrong. She starts fine, but immediately dies in fuel. Only manually regulate idle with the accelarator pedal can maintain idle. idle is on 1200 to 900 across the range, base running airflow is about 30 - 40% raised. After about 30 seconds she can maintain idle by herself. Hi-, Low-Octane tables are matched, also the throttle closed in P and Drive are matched. My tuner can't find or is not motivated to help properly. Hope You or someone who reads this can give me several tips to get my Firebird started. Funny part: If the outside temperatures are rising, about room temperature 16-22°C, 60-70°F, it is possible that she fires up and runs like a dream.
Regards
Hey man did you ever get this worked out? Your symptoms sound identical to mine.
How did you tune the Idle Timing advance in park? The VE in idle area? In open loop > Cold Warmup/After Start?
@@Guiohms.m50
I do this trial and error, and I'm nit really sure what to do. The idle advance in Park and In Gear I set 24 degrees up to 1200 rpm and from 0-0.28.
I don't understand the VE and only working on a tune that based on nutty tuner who thinks he's the LS god of europe...
I'm really scared to get to deep in this and screw up. After start enrichment and that stuff is stock.
Base running airflow on 0-40 degrees C is round about 45 g/s to 30 g/s and interpolates to down to 10.5 g/s from 80 degrees till the end of that table in Gear and in Park/Neutral as well.
I'm experimenting with startup initial, startup initial decay, STIT and some tables I understand what they're going to do. FA Multi Stage is also trial and error.
A while ago I was thinking to get this HLHC out of the block and stick back to 02-04 c5 z06 cam...
Now it's going to be colder in the mornig and that fucking car struggles again in coldstart.
Hope that helps, but I don't think so...
@@navybluethunder In France we have a LS god of Europe too ahahah
How is your EQ Ratio (Lambda ratio vs ECT)? Stock?
Because you start in Open Loop and stay in OL until it's enter in CL. Probably why you can't stay in idle until ~30 secondes. If you have too much airflow at startup and it flares a lot, the engine can bounce in RPM and die too.
@@Guiohms.m50
The EQ ratio is set up to, but to what I don't know. on the high performance column the numbers are up to 1.00. rising on up to colder ECTs. That's all I can say in this chat. You know CCRP? He has tuned my engine on this high lift hotcam. it runs like a dream when warmed up, but like crap when cold.
Now the car starts fine but struggles a few seconds after startup for three seconds or so, then start up initial protocolls come in...
It's merd X-D
Does this apply only to gm? Reason i ask is i have a 05 300c 5.7 and installed a high horse performance stage 2r cam along with other supporting mods...
The car will start and run as long as i have my foot on the pedal then immediately die once i take my foot off.
Need to adjust your idle airflow table most likely
@@GoatRopeGarage 10-4....is that something that i can do or do i need to let a tuner do it...i watched a video earlier where a guy used hp tuners to adjust his idle after the cam install because his wouldn't idle either.
@@ron7922 it's fairly easy, just a trial and error kind of thing where you dial it back a bit, see if it helps, then keep adjusting. When you put your foot in the gas you're no longer running the idle control and so that's always a good indication that your idle airflow and possibly spark is off.
Talking about cam related stuff for 3 minutes before actually talking about tuning awesome
