Ok I'm kinda new to these e 40 pcms and they seem like a pain in the ass. Its pretty different from a ls1 pcm. I can't find where to delete the torque managment, also I added 2 degrees of timing on a 05 gto and the knock reading goes crazy. Can someone please enlighten me on whats going on and how do I go on tuning these pcms?
Thanks

Ah, thats because TM is in the TCM not the ECM...have to read both the E40 ECM and the T42 TCM. There is a bunch of info in a sticky by Gelf VXR (I think) that is full of great E40 tuning.

If you want to burn rubber from a stop you could max {B0704} in the ECM.

Worked for me!:shock:

Just need new tires now.
