I have a 92 jdm h22a in my 98 hb and just got a obd1 (maybe) p13 ecu but the car sounds like ****, its running idle at 200 rpm steady and hesitates when gased. And there black **** (fuel I guess) spraying out of the exhaust. Any Ideas?

 

ur fuel injectors wired up right?

check ur distributor wiring too.

 

did it work before you plugged in the p13? its most likely something else.

I actually had the same exact symptoms you described once, and it was caused by a loose ground.

EDIT: I didn't have 'black **** shooting out the exhaust.' check your firing order, valve timing (sounds like you could possibly be off by one tooth), distributor wiring, grounds.

 

yeah, I had a chipped p28 in it and it ran fine exept for vtec engaging at 6700 rpm??? I talked to a guy who said a p72 is the better ecu to go with on a h22a swap so Im gonna try that and see what happens. He also said that having the bigger fuel injectors might be the case. I have the black ones.

Idle problems, hesitation, and black **** all sound like timing issues. Put a timing light on it with the p13. I had the same prob before when I switched ecus. I had a chipped p28, and my ignition timing changed when i put the p13 in. It hesistated so badly that the belt jumped a tooth. Redo your timing, it worked for me.
