We have a 5.7 from a VZ Commodore being transplanted into another car and I cannot seem to get the electronic throttle to work, the wiring is correct from the pedal to the TAC control as is the wiring from the throttle body to the TAC. the only other wiring is the two UART serial data wires that go to the computer (OK) The TAC has power to it.
he only wires not yet hooked up are the cruse control. I have tried to data log the pedal and am getting nothing. The pedal is sending a variable signal to the TAC but nothing coming out and I have tried another pedal and TAC control, any suggestions
