I can get a PR4 ecu from a 91 teg. I want to chip it and run a ZC engine with it. I know how to chip and all that and I can get stock ZC ROMs so its not a problem. All I want to know is if the PR4 is a good canditate for the "PM7 emulation" . Also will it fit inside a PM6 casing? My PM6 ecu is busted so I need anotherone. The pr4 is just something I can get my hands on.

Sure, you can chip a PR4 to ZC spec. I don't know why you would want to swap the cases though.

I'm getting a PM6 now so it won't be an issue. I thought the case would have to be swapped because the integra PG7 is different then the PM's so I assumed that the PR4 would not fit the bolts.

The PG7 uses the same bolt pattern as the early pre-OBD Civic ECU's, that's probably why. I would think the PR4 uses the 88-91 Civic bolt pattern.

the pr4 kinda fits...you can get 2 bolts in but i don't know about the metal floor cover, i've never put mine back.
