    Heres my tune file if anybody cares to find something I've missed. Engine and trans are stock as far as I know.

    Tre-cool, I didn't get a chance to load your tune but I'm assuming it works. On that same day a friend emailed me a bone stock vette file that fit in the compatibility column. I figured I'd start with the cleanest slate I could. I made the basic VATS changed and loaded it and the speedo worked (not accurate yet, but it moves)! I still have the resistor in place from before. I am considering removing the resistor and see if it still works then maybe load yours as well. Maybe I'll do a little experimenting to see if I can make some sense of all this. Why do some E38 systems work and some not, etc. I guess its part of the software in the background that EFILive doesn't give us access to??? Maybe this info will help others. Do NONE of the truck and Camaro e38s work, only the ones from a vette, due to the background settings?

    Thanks for the help guys.

    well when i played with mine. i tried the camaro e38 os for both the ecu/trans & couldnt get the tapshift to work as a hardwire.

    but the holden ecu tune with the camaro tcm base would work. so go figure.
