I know you guys don't support the old 96 Chevy tahoe ecm to edit but the scanner does work, it's just missing the most common needed PID. the one for Camshaft Sensor Retard (CMP Retard) used for GM Vortec 4.3 and 5.7 liter engines. it's needed any time you have to pull the dizzy out or move it. to resync the cam timing.
I read that there's one of those blue tooth China obd 2 scanner with a phone app, car gauge pro that has it. but while a friend of mine had one that would work with these trucks, I tired ordering 2 different ones and neither worked. they looked the same but would just cause the stock CD player to try and eject when I plugged them in. very odd, I've since moved a state away and can't borrow his. I'd love to just use the scanner in hptuners that I already have.
any chance?
