Ok I've got some intermittent check engine codes for some stupid reason. If I switch over to a P28 ECU would it run ok. I've heard before that it won't run right but I don't see any reason. The engines are close enough, hell if you can run a Y8 on a Y7 ecu why not. It's in a manual 96 CX with a Y8 harness, engine and ecu from a 98

 

It'll run, but it'll run like ****. The timing on the Z6 and Y8s is very different.

 

Humm

 

mine runs pretty damn good...d16y8 in a 95 del sol obd1 on a p28. 27mpg beating on it 35 highway.

 

does the Z6 have more or less timing than the Y8. I'm guessing less, which might be ok since my Y8 has 10.5:1 CR that might be enough to make up for the cam difference.
