i have a ZC DOHC and im using the ecu off a 90 integra 1.8 Non-Vtec (PR4) is that a good ecu to use or should i try to find a PM7 or PG7 ecu?

 

Stock ZC ecu would be best..Dont use the old 88-89 teg ecu though it runs the motor way to rich and the rev limit is set to high..The one you have now is ok but its probably running a tad bit rich and you're probably losing power and losing mpg..

 

the stock ecu is the PM7 right? any suggestions where i could find one?

 

Yeah stock ecu is pm7..You can find them on here in the classifieds section..sometimes on ebay also..Or theres another choice,You can chip the pr4 ecu and run stock dohc zc fuel and timing maps..Its up to you though..
