    E38.
    The E40 is no longer used on any new vehicles.

    Cheers,

    Im pretty sure its because GM is using the E38s and E67s exclusively on 90% of their vehicles now, saves costs on having 5-8+ different ECMs. But thats just my guess, Ross might have a better explanation as he knows the internal code of the ECMs.
