    The Escalade L92 is run by an E38 from GM, so that should work (it does have the 58x reluctor).

    I think you need to use a DBW tb, but then again they come from GM with a DBW. You might be able to use a cable tb, but Im pretty sure most trucks from GM are DBW now.

    Edit: L92s us E38, not E67... Thanks Ross.

    Yeah, you will need the E67 and DBW, because there is no cable throttles on 2007 motors with the 58x crank. None of the GenIV ECM's have idle stepper outputs (to use with a cable throttle).
    E38 would be an even better option as that is what the L92 used.

    Cheers,

    The E67 is really just an E38 'with the lot', it has more inputs and outputs which is why they use it on the boosted applications. However, as Jason (from Lingenfelter) pointed out to me a while back, the main difference is the E67 still has a ClassII data bus signal, on some platforms (like the CTS-V) they had not changed all modules over to CAN, so they still needed an ECM with the older communications capability.
