    Re: OD Transmission Discussion (Hijack removal)

    Sounds like I'll need a TPS breakout, a connection to the DIS corrected tach signal out of the ICM, and jump off of the 3 bar MAP when I install the turbo. I am a mad scientist and I'm putting the L67 EFI system on the car which has 4T65E controls in it but from all I've been told I can't try to trick the PCM into thinking its running a 4T65E with polarity reversing relays and the like when its actually connected to a 4L80E.

      Nope. If you're running the standalone TCU, you'll trick the PCM into thinking that you have a manual trans so that it ignores the factory trans harness--If I'm following you correctly.
