Default What ECU do I have?
I got a 91 civic hatch CX.... yes a CX with a 1.5 engine. So I'm wondering what ECU I got and If I can re-program for a ZC swap? Anyone know?

Can you tell us what that equals in the US? Is it the DX or the STD?

Either way, it's probably the PM5. You cannot re-program that or any ECU to run a ZC. Just find the ZC ECU, or use a Teg or Si OBD-0 ECU.

ZC is basically a twin cam D series engine.
