No throttle unless 4 speed automatic was selected. Since the update no matter what selection I make there is no throttle. I've contacted multiple shops and they are having the same issue on any software later than 4.0.12. I can't flash trans and engine seperate on my year.
I flashed and reflashed several times with different options as well as going back to the original file that worked and I've gotten nowhere. Seeing that others have the same issue I feel like it has to be in the software and being I did nothing but update software it seems to narrow it down to that.
