The reason I am asking is mine just arrived in the mail and I need to program it.
My car is an 03 GTP and the programing options are "all ISO and VPW vehicles" or "all PWM vehicles" there are different tables for VPW, PWM and ISO vehicles.
I think that I need to go with "ISO and VPW" as one table states "GM VPW".
The other tables are CANxx, Ford PWM, Ford Can, GM CANSF, VW ISO.
What does ISO, VPW and PWM mean?
I'm pretty sure but not possitive about the GM VPW.
Thanks guys
