Re: Help, predator wont work Well they ( Diablo ) were correct in the manual. The ON STAR was the culprit. Unplugged all the associated fuses and it worked. OnStar interrigates the auto when it is on to keep it in the system. It does this often and the ECU gets interrupted for a few cpu cycles doing housework causing the tuning you are trying to do to fail. Oh Well I guess I am guilty of not reading the instructions. Will let everyone know how it works and what tranny settings work the best on the Hummer.
