I just dropped an LS1 in my 02 GMC Sierra and reflashed the CPU using HPTuners and a stock 6.0 tune from the Repository. Problem is, the Electronic Throttle isn't working properly. I've double checked the wiring and all is good. I'm thinking there is probably code in the software for an ETC that's missing. I see Serial Data connections from the CPU to TAC module.
Can someone upload an HPTuners stock bin that has an Electronic Throttle? Or email it to me?
lcts04@comcast.net. Preferably from an '02 pickup. My license is just for that year truck.
I've put the stock LS1 throttle body back on to get it running.
Thanks for any help.
