the 88-89 integra ecu will plug right into my hf wiring?

 

Yes, but the ECU will not bolt to the floor in the integra case. Get another ECU from the junkyard (or use the case from your HF) and put the Integra circuitry inside of it.

 

It will hook up but run a little rich and your redline will be 6800. If you go with a PM7, the A/F ratio will be exact and redline will be 7200. Check eBay for the ECU.

actually, the integra PG7 has fuel cut-off at 7500rpm and having tried PM6, PM7 & PG7 on the ZC, we get better performance with the PG7 - as for running rich, if your O2 sensor is doing it's job, it will adjust the A/F ratio - hasn't been a problem for us.

 

I have used the Integ ECU and the ZC ecu, I stayed with the ZC just because its a little bit smoother...

Correct, but if you read my post I said redline was 6800...for the TEG..

the 6800 is the redline on 90-93 PR4 tegs ECU when warm. PG7 (88-89 teg) redline is 7200 when warm and 6800 when cold...PM7 is the ZC ECU which is 7500 when warm
