I haven't had a ZC in awhile I thought I heard that the 89 Integ ECU was the best but not sure???? cause I'm starting a new ZC project and I have a 89 Integ ecu.
Any pro's con's??? TIA Rob

 

89 integra is a good choice but it may run the zc a tad rich. The PM7 ecu is the best choice since it was designed for the zc. The pm6 will run the zc but on the lean side of the afr. The PR4 ecu will also work as well.

But since you have the 89 integra ecu I would go ahead and use it.

 

I've been running the 89 teg ecu for a while now on my zc and it runs great. still get good gas mileage too.

 

Do you know about how many miles per gallon you get... People say the 88-89 teg one makes it run rich ive never seen that problem either i plan on going with that one because the actual ZC ecu has a low low speed limit cut off

 

112 MPH IS LOW LOW????

In a CRX????

Thanks, without people like you there wouldn't be jobs for EMTs.

 

im running a DOHC ZC on a PG7 and im checking my gas milage now. ill let you know exact when i go empty.

 

I've personally have had both, and I would recommend the PM7 anyday other the PG7. Just my 2 cents.

 

yeah i think it just differs on certain applications..

 

I ahad an 89 teg ecu running my zc years ago, worked great, no problems runing rich.

Freinds have tried zc ecu's before, but got check engine lights due the different ELD (electric load detaector) from jdm to usdm cars.

 

ELD codes shouldn't trigger CEL's... odd.

 

i felt no difference with the pm7 over the pg7.

Well I guess it's better to run alittle rich caus ewhen you start adding header exhaust in will lean out abit. Thanks guys! Rob
