well, to actually answer your question since no one else has said anything, the pm7 is the ecu thats actually for the zc. pretty hard to come accross though. what im using is a pg7, its from a 88-89 integra. runs the zc good but is a little on the rich side. you could also use a pm6 which is from an 88-91 civic/crx si. that runs things a little bit lean cuz its meant for the sohc.

I second the PM7. It runs the car the best IMO. I've swapped between the PM6 and 7 and found the PM7 to run the engine alittle more smoothly and it feels like it has more pick up. I tried an LS ECU but kept smelling raw fuel. Switched to the PM7 and no more fuel smell.

sweet i will have to see if i can get a pm7 maybe off ebay, and if i can see if i can get one thats chipped already, or maybe just keep it stock what do you think.

pm6 sucks on the zc..dont ever do it..its like night and day with the pg7 and pm7..

I have a chipped pm6 for my ZC and i love it. But i would like to see what a pg7 or a pm7 would do.

hmm, u guys think the PM6 doesnt work well with the ZC??? i havent really had a problem, i even used a pr4 and didnt notice any change at all either
