I'm having an issue where the truck is limiting the throttle angle in first gear (like traction control but advance track is off). This seems to be limited to first gear only and I've maxed out everything that I can find that looks like it could cause it. Does anybody have any pointers on where to look?
Need a catalog to be able to see what it's doing, posting the tune will help as well
Log using this channel config and this file, IDK if it will fix the issue since you weren't logging fuel source, but give it a shot and report back
- Set your fueling to .76
- Refined your VCT OP table a bit better
- Refined your PE table a bit better
- Turned off anti-Jerk
- Raised modulation to max of 738(max allowed by table)
- random other little shit mixed in there
That seemed to have fixed it. Thanks so much for your help.
Why .76 lambda vs .80 or a little leaner?Quote:

Better safe than sorry. You can make it lean later after you have everything dialed in.Quote:

.76 is cat protection territory.
Bc he said he has issues with the tune and I wasn't sure if it would fix the problem with out him logging all the correct channels and trying the file I posted. I also didn't check to make sure all the other changes were good or not, didn't even look at his spark tables. So .76 is a decent middle ground considering the original file he posted was commanding .72 lambda. Now it's up to him to finish tuning his truck for more powerQuote:
