hello how is everyone i have 2020 sierra 5.3 with global a ecu i am trying to tune the cutoff on P/N to reach 6,000 rpm but what is happeing is after i edit my cutoff and test the car on manual shifting it reaches 6,000rpm and start bouncing off the revlimiter fast but when in P or N it will only reach 4,000 and stay there not like 2017 gmc what is does on manual shifting is the same on p/n what tables need to be edited please
I have tried all I can. But the throttle seems to close when going WOT in Park Neutral. I wish I had a test vehicle to try. I don't want to try on a client's vehicle. LOL
One more thing. If you find it please share, willing to pay USD 100. I love bouncing rev limiter.

Aboturky, I just emailed your file back
still no luck the same problem
Check out driver demand at 0 mph and see if it looks weird.
let me check that
it looks weird but i already test the car lets say at 30mph put it in neutral and rev the engine still it will reach 4,000rpm then starts to climb up slowly as of torque is being reduced
In Park/Neutral when you rev the throttle is stuck at 35%. There is a slight jump like to about 60% and then it comes back to 30-35% even if the pedal is 100%
I still didn't find where is that throttle limit which is only for park/neutral only.
In case a vehicle comes by, what parameters do you want logged ?Quote:
