Thanks for the info! I do have all the wiring and I'll be keeping the mopar PCM to control the Transmission. For the engine I've pretty much figured out how I'm going to piggyback a Megasquirt MS2 ECM using a 36-1 trigger wheel on the front. The megasquirt will batch fire the factory injectors and trigger LS truck coils for Coil-near-plug spark.

This is very similar to the Megasquirt Setup that I have on the 5.3 in my C10 and I'll be able to tune the ECM myself.

It sounds like you hit the limit of the OBD1 setup with yours and are in the process of moving to OBD2. If you are interested in the Megasquirt piggyback option instead of OBD2 I can share what I know.
