93 Mark VIII
I meant revert the car back to obd1 and get rid of all the troublesome 96 only electricals. Hence why I said find a wiring harness as well. I mean I'm sure its not as simple as that, but id do it if I had a bastard child 96.
leave the 96 computer. its fine.
just run a tune that kills the IMRC code and ignores the second set of O2s, run 93-95 IMRCs, do whatever you want with the cats.
after that, the only big things are the computer and VRCM.
