I recently did a ZC swap. I want to know what ECU is better to have. I did some research and discovered that the ZC has a 7200 rpm redline. One of the major reasons that ZC's blow up is because many people confuse the Integra computers 7800rpm fuel cut off as a red line. Also I have heard of the problems of ZC's with integra computers running to rich. I'd appreciate any input on this topic.

 

The ECU you want is the P28 92-95 EX/Si ECU.

 

i don't think so: p28 is a obdI ecu for sohc vtecs...

for 88-91 civics with d16a6 or zc or even LS, you can run a PM7 ZC, PG7 (88-9 integra), Pm6 Si (90-1 higher rev limit), and Pr5 from JDM teg zxi or pr4 from 90-1 teg rs/gs/ls

by far the PG7 is best on ZC, and cheaper then ZC ecu ....

 

Oops, my bad.

 

I had the 89 ls ecu for my zc and never had any problems with it and i also shot a 65 shot on everyday and still never had any problems with the motor. You can get a ls ecu from the junkyard for about $75 or less.
