low commanded throttle opening when rock crawling
I have had an issue where if I roll up to a rock wall and try to climb it the ECM limits power. This is a 2018 Colorado ZR2 with the 3.6L v6 and 8sp. This is happening when I am in low range. I have 4.56 gears installed. I want this to climb the rock wall or spin tires trying and not just sit there. It has done this since the 4.56 gears and Trifecta tune was installed. I have removed the trifecta tune. I now have an unlocked TCM installed also. Can someone point me in the right direction to fix this. At first I assumed it would be something in the torque management but I have not figured it out yet.
I have attached my tune and a log. In the log file the vehicle was tied to a tree. You can see the TPS goes over 80% but the commanded throttle position stays below 30%. Anyone have an idea for me to try to fix this?
