Really hope the channel gets huge, learned so much from this channel that I struggled to learn reading books and hopping on the forums. Still learning every time I watch a video. Hoping to tune my 2017 Camaro soon and I have a 81 Camaro I’m planning on doing a turbo LS swap.
Thanks and thanks for watching!
Gen V tuning, let's GO!
That's what I'm talking about 👊
Another successful video 😎
Whew. I haven't touched a Gen V yet BUT I have tuned a newer cammed Mopar with the torque based setup like a Gen V. This is easy to follow since I have this experience...
One thing to pay attention to is when doing percentages on the torque tables is to be careful with negative numbers. Multiplying by decimals will take them the wrong way if you aren't careful.
Excellent video as usual 👍
Yep, makes you have to spend a lot more time dialing things in when you're working on the higher end as it is very easy to accidentally hit negative values in the lower spark ranges.
any chance for some gen4 (e38 ecu) big cam idle tuning basics videos in the future?
Old video but you got a sub for life here. Thank you for the info.
What about fueling? A bigger cam with more overlap is going to be pushing more O2 into the exhaust, so the PCM will be adding more fuel than necessary. How do you compensate for that issue? Very instructive video, BTW.
Thanks so much for your videos man. Thanks to you i will start tunning my own engine.
always great information, thanks @GRG
Thank you
I have a stage 3 Texas speed cam on a 2015 gmc and my long term b1 is running really rich im running a 0 degree block
Soooooo, I’ve watched all your videos 500 times and I swear my 2014 e38 ecm has hidden idle torque tables like the gen 5 ecu’s have. 5 years so far 6 known tuners have not been able to get idle even close and I’ve gotten close, but not close enough. To me, it seems like a torque issue cause it is a manual and when I have idle as close as I’ll get it and throw it in reverse and add some load to engine without hitting throttle, dam thing idles perfect and happy and scanner looks perfect everywhere. I just can’t access the right tables or I can’t adjust torque tables correct under edit tab correctly. Hp tuners list my ecm as a. E38 gen 4. Car is a 2014 Camaro ss2. It’s not supposed to have next generation limited slip tech either, yet I get warning signals on dash like gen 5 ecus. I can tell u it’s physically not on the vehicle though. Has electric power steering too. I’m throwing a centrifugal on it as soon as it gets delivered and hope that puts enough load to simulate say reverse gear load without throttle. Unless you’ve dealt with this and have some advice. Thanks
old video but can you explain exactly what speed control reserve is. you explained external load well but didnt say much about speed control reserve
🤯 according to this my tune is jacked, thus explaining my misfire issue.
Did u get ur figured out im having a misfire issue on mine also
So the external load table relates directly to my zero pedal engine torque.
And delivered engine torque relates to virtual torque tables .
And the goal is to make them as close to each other as possible .what about speed control reserve table what pid does it relate to ?
You know of we can uderstand these torque pids and which tables exactly do they reflect on the scanner that would make it so much simple and easy to tune these gen 5 any chance of a video explaining these kyle maybe soon enough? Great video by the way.
Thanks for sharing.
When tuning Driver demand and it’s referencing axle torque; is there a way to calculate what the engine torque maybe?
Love your videos..new to tuning .kinda stuck with a 2011 5.3 6l80 btr 481/481 cam arm and did delete.ls3 sprocket.fighting hard gear engagement at stop...lost...is this a torque modeling problem?i haven’t changed anything on trans.tune is stock on Tom.stock converter.lost...??
'14 ATS 2.0T. - I've dialed everything in with a larger TB and larger Dia. MAF housing... except for idle. Originally I got TONS of negative timing (from tq mgmt advance) at idle. Adjusted my Virtual TQ tables accordingly and got things really solid at idle, back to +15-20* timing... ONLY when AC is on. As soon as I turn the AC off, idle goes completely erratic, with huge timing and throttle swings.
Cannot figure this one out and it's driving me nuts.
Haha, that's crazy! Check to see what your AC table is doing, I can't remember if they are torque or load on those, and try and make the adjustments to your base torque to make it run like ac on, you might then have to adjust the AC on parameters. The torque based idle setups are so finicky. Just a lot of trial and error
Ok easier question, if Zero peddle engine torque is 50'ish and engine torque is 75'ish. Do I go up in that area on the torque maps or down? timing is around 0 to 6
Would any changes need made if you just bump the idle set points up on a stock cam? I raised mine to 600 to get a smoother idle. Is there anything that can be tuned to smooth the stock idle rpm other than just raise the set point?
Not really, the adaptives should keep it as close to the set rpms as possible on the stock cam
Would this work for some of the Gen 4 motors? I have some of these tables on my gen 4 tables.
I have paid for a recent expert tune on my TT 11 Camro with a cam. The car responds excellent but from around 20MPH-65MPH when the pedal is steady or cruise control is set the RPM/IDLE pulses up and down. Above 65 MPH or in acceleration the car runs perfect. Is this something being new to this all I can look for and perfect myself? Thank you and WOW most if this is WAY over my head but I am certainly learning from you. I should have said - prior to the tune this was not an issue. Thank you!
Sure, fist verify that your fueling in that area is steady, then look at your timing and make sure it is steady.
👍🏻👍🏻👍🏻
thanks for learn that , I have do that even in high RPM ? og just for Idle ? thanks
Useful video as usual. So why did you choose 50 as a torque limit in the external load table?
Think of that table as all the devices the engine is powering while you are at idle, vacuum pump, ac compressor, alternator, etc. We are basically saying it shouldn't take more torque than this to achieve idle with our loads. With a belt driven supercharger it is going to be higher. Also keep in mind that torque is calculated off of your airmass readings so if you don't have those dialed in nothing you do will probably help. On this platform we have to just get it running so we can do the airflow tuning so that the torque will start to read correctly to allow us to tune things like this.
what Happens if you have a E78 2014 2500hd. Which is a gen4 with a gen 5 ECU? I would use this video as reference?
If I have L86 cammed TSP 218/226. And it's been tuned on 93 runs great idles great. Before the cam I previously enabled the E85 and added a sensor with HP tuners I own. I know the tuner didn't work on any E85 stuff and he did a great job and I needed it up a runing fast since it's my DD. I been spending sometime getting the shifting dialed in and smoothing the MAF and VVE tables with a wideband I have now on the truck. When it has E85 in the tank my only complaint is. It's slightly jerky when coming to a stop at a red light. It's doesn't do it on straight 93. Could I copy what he changed on the Virtual Torque>Airmass and MAP tables and add that to the E85 virtual torque tables? Then work it from there?
Two questions,
Would this apply to a gen V lf4 motor such as the ATS-v? Looking to upgrade next year to one.
Do you have a gen 4 idle tuning video in the works? That's where I'm struggling.
Any DI Gen V is going to be torque based as far as I've seen. Gen IV still use airflow, and I'll be doing a video on them soon.
@@GoatRopeGarage Awesome. Your videos, by far, are the easiest to follow and understand. Thank you!
@@TheHerokid672 I appreciate it and thanks for watching! Plenty more to come!
I have a 17 Silverado 6.2 just did heads and cam and it’s not wanting to idle unless I’m touching the gas the slightest bit , I barely have to touch it and it’ll run, I let off and it dies any help from anyone would be appreciated
Base idle airflow is probably too low
How do you get rid of the o2 sensor code after header install?
Read the codes in the scanner to get the DTC numbers then go to the DTC list and change those to no error reported.
Goat Rope Garage thanks man 🙏🏼
and Omega moo!
may i ask about the fuel status, in the first log it shows fault , and the second log its normal.
can u plz explain how u fix this issue? am facing same problem with 14 turbo silverado after first startup.
Not sure on that one, getting any DTC's?
How can I get a tune from you?
How come my throttle body and pedal podition is only showing 84% SAE at WOT?
SAE is a standardized range, you'll never see 100%, log the non-SAE version and it will be a better representation.
Do you have to dial in VVE tables when just running MAF all the time to make the torque tables accurate?
You should. At the end of the day torque is based on mass airflow, but don't confuse that with MAF as you're still calculating mass airflow when running off the VE table
@@GoatRopeGarage So dialing in both the VVE tables and the MAF sensor is not necessary If only going off of one or the other, but dialing in both is the recommended thing to do? Or will the torque tables not work correctly if only one is dialed in. Thanks for the help.
can you write me a idle tune file i cant get it figured out
Is it okay to get the motor idling pretty good and then go in and tune maf and ve tables after cam swap. Also what is considered a big cam?
That's what I like to do. Depends on the application, what kind of cam you talking about?
Texas speed stage 2, 218/226 .113 lsa. I'll try to make it to your live stream tonight , I work nights so I'll try to dodge the boss.
Anyway I can get a little help on my hp tuner 2002 Camaro 35th just did ls6 port polished and milled heads with .660 dual spring with a v4 cam 611 over 636 lift and I am just lost lol thing idles like shit and spits fuel out the exhaust so running super super rich I did also long tubes slp loud mouth cat delete and had it tuned for that just not head cams
Check out the Gen 3 section, should get you started. You need to retune your VE table for starters.

Thanks in advance I’ll get on that if I have any troubles I’ll let you know and I’ll send a link to a video and you can maybe view it and lmk if anything is off just give me some time
Yo can you help me
