UPgrade a 93 to 94-95 ODB1 Computer?

Can it be done? I hate the chipped PCM's. Can i slap in a 94-95 computer and be done with the madness. I know i would most likely have to change the knock sensor. Any gotchas here? or do i juat live with a chipped PCM? Logging and tuning is SO easy ODB1.

Having done a 93, I prefer it to the flash pcm.
And you can't just swap the pcm either...the whole wiring harness I believe.

I agree you need a complete donor harness from a 9/95 car. Even a 96/97 would work because the PCM connections are the same. Just use a 16188051 PCM.
