is it easy to swap a obd1 into my dohc zc motor i thought they came with that ecu but mine hase a b18a1 ecu and is seems like its running too rich im trying to figure this out because it bogs in the low rpms and my new plugs are black already i have a aem fuel presssure regulator and rail and a msd but its still to rich should i obtain a obd1 or what

 

Are you saying that the motor is OBD1 or you want to go OBD1? I would assume you have a DOHC ZC from a 88-91 crx si. If so then the ecu you currently have is wrong. You want a PM7 or PG7 ecu.

 

well i have a dohc zc motor but my ecu is a b18a1 non vtec one i dont know how it got there i bought it like that i thought the zc was obd1 maby im mistaken

 

It dependes on what year the motor is

 

get a 89 integra ecu at a local junk yard

 

Some ZCs came obd-1, but that doesn't really matter.

You will want to completely forget the obd-1 stuff. Just run a pm7 or a pg7. Or you could get a 90-91 pm6 ecu and chip it with pm7 fuel maps (with TURBOEDIT and no other program).
