I quit updating when the snow shut me down, but I had made several attempts for a fix that didnt work. It was making me nervous to spin the rear wheels in the garage up on blocks at cruise speeds.I will list what was tried.
reflashed new pcm.
reflashed again with original pcm when vss was still at half speed.
swapped out throttle body and dbw pedal.
I think this was everything.
The tuner revealed to me that the tune architecture is for an auto trans vortec truck 5.3 with fuel maps for an LS6 Vette. I believe the 12v wire going to pin 33 blue sounded like the fix that should have worked.
