have you tried a different ecu? sounds to me like it should just work.

I haven't tried getting a new ecu. Is there any way i can check the ecu without buying a new one?

If any of your friends run h23, see if they will let you plug their ecu in and see if it works. If it does, you know your ecu is bad, if not then... sorry

All my buddies run b or d series, how about a p13 ecu for the h22 would that work for the h23?
