Hi and thanks for the help,
I've converted an LH6 5.3 with an LS2 intake and throttle body. It's installed in a Volvo. Still figuring out the wiring. Have triple checked right to the ecm . Starts and idles fine but no throttle operation. Several throttle codes. New GTO accelerator pedal and new GTO ls2 intake, Throttle body. Wiring harness from the Envoy/truck. I'm wondering if I need the GTO E40 ecm or should the truck one work fine.
EFIlive won't let me flash the truck ecm with the GTO program because of different operating system.
Engine completely stock except headers and intake/throttle body change.


Thanks , John

You may have to use the throttle pedal setup and ecm from the same type of vehicle. Your best bet is to call someone like Speartech for an absolutly correct answer.

I've contacted EFIlive but no response yet. Hard to believe I'm the first guy who installed a car intake/TB on a truck motor.

Thanks, John

Well an eye opener to say the least. Talked to Speartech, very nice by the way, and he thought either would work with the other. It's just not the case. One must use the pedal, ECM, Throttle body all from the same setup.
Different operating systems for both setups. All also have different resistance values in the APP sensor(pedal).
