    I assume your Integra ECU is a PG7. I have an 89 Integra PG7 in my CRX with my ZC engine. I wouldn't put back the SI PM6, because the Integra ECU has more aggressive timing and fuel maps. It will simply work better with the ZC engine. If anyhing, I would love to get my hands on PM7 ECU, which is actually made for the ZC engine, but they are expensive and rare. I was also told that if you chip the SI PM6 ECU, that PG7 will still work better. I'm not 100% sure about that.

    i have heard nothing but horrible things about the zc ecu, kinda like that it tends to make up its own mind about where the rev limit should be, and does it very often. that alone would make me not want that thing!
