i am loking for a pm7 for my zc, but as u prolly know there hard to find. i could get a pg7 from an integra if i wanted. i just want my zc to run the best that it can. so my question is, is there any major perfomance diffrence betweet the 2 ecu's??
my car is a 89 crx si w/ zc and 91 si tranny, and i have basic mods. (i am still using my pm6 ecu right now)

 

I have a pm7 for sale..

The 89 integ is supposedly a tiny bit faster...but this has never been proven to my knowledge. Neither ECU feels any faster then the other.

I have had both on a dual cam ZC...

I do know that the pm7 runs a bit smoother.

 

well they all feel beter than the si ecu... but really the teg is a little beter than em all imo the jdm si ecu has a mph limiter and the teg does not..... so go with it

 

I ran a Mugen chipped pm7 and I would suggest going with that
