What changed about the ecm starting in 96? Did it go to OBD 2? How much harder is it to re program the newer ones? I ask because the newer the engine, the better for emissions-legal swapping.

yes it went to OBD2, prom is not removable so entire ECM has to be sent in for a reflash. OBD1 you can set yourself up to tune pretty reasonably not so with OBD2

Thanks! Once it is working, can you put on a manual pump and have the ecm continue to run the trans? (for off road use only of course)

As far as I know if you go manual IP then you will have to run a stand alone computer for the trans. I believe you can mod the existing harness to work. There are some guys here that have gone through this process and I am sure they will chime in shortly.

Nope.
The obdii PCM is looking for the APP signal which is essentially 3 TPS's.
Find a 92/93 TCM or use aftermarket controller. You will still need a TPS, but just a "traditional" single one on the throttle linkage.

Burning Oil sells an aftermarket trans controler, IIRC. Check out his site.
