If you are trying to run the STOCK ECU there really isnt a STOCK ECU for the DOHC ZC. You are better off running the CRX SI PM6 IF YOUR CAR IS OBD0

If for some reason you have this motor in a OBD1 car (92-95) then Tom is correct, the closest thing to it is a LS ECU which would be PR4 or P75

but why keep stock ecu if you are planning on mods?
