    Default EFI Compatibility

    Simple question here.

    https://paceperformance.com/i-238494...-pressure.html

    This is for a GM part number 19355174, LT4 6.2L 650HP Engine Controller Kit with an 8L90E.

    The question is, will EFI Live talk to this standalone controller? If so, this opens the door to converting damn near everything on this board into an 8 speed automatic. I have a half dozen projects alone in mind if this will work.

    Based on previous GMPP/Chevrolet Performance stuff, it likely uses the same production E92 hardware with a different/custom GM OS. So the question is, how different from a production E92 OS is it to map out for tuning purposes. Unfortunately, the best way to truly know if it's supported would be to get one and hook it up either in a vehicle or on the bench and try to read it.

    Fingers crossed they are not E92A and T87A controllers. If E92 & T87, should be AOK!

    Hopefully NOT a T87A as they have digital signatures, but looking at the picture that isn't a T87 anyway, I have no idea what the TCM is.
    I no longer monitor the forum, please either post your question or create a support ticket.

    That looks like the FPCM unit in the engine harness pic, this is a T87 shown with the trans yes? :-
