I have a 97 civic coupe dx (was auto) I recently converted to manual and swapped in a b16a2 swap from a 2000 si. I used the original harness did the 3 wire to 2 wire iacv conversion and also the 3 wire to 2 wire cfk plug. Everything is plugged in im currently borrowing a obd2a p72 ecu (gsr) which it runs fine with but runs a bit rich. I recently bought a obd2a pct (ctr) ecu but idles very low almost ready to die. Acceleration is fine but when I let off throttle the engine almost wants to shut off..


My question is: is this jdm pct ecu compatible with a my us b16a2?*


Thanks in advance!*

 

you need a USDM P30 OBD2A.

 

both ecu's are very very wrong. dual iab's on gsr, fuel mapping and a dozen other issues.

 

Well I know the p72 is wrong I borrowed it just to see if there was something wrong with the ctr ecu or the motor.. I havent had any luck finding a obd2a p30

 

the ctr ecu is nowhere near right, either. convert to obd2b and use the em1 ecu.

 

Obd2a to obd2b jumper harness?

 

Em1 p2t ecu will through codes for ftp sensor since the hatches do not have one.
