hello guys about 2 years ago i posted starting problems with my b20b swap. the car was not starting or it would shut off while i was driving. when the car would shut off it would kick on the check engine light. it would not start untill the fuel relay would click over then the check engine light would turn off so at first i thught it was the relay switch but then a buddy of mine brought over a stock ecu for the car and since then it has has no issues except my car does not run like it did witht the mapped and tuned ECU. any suggestions on what could be wrong with my tuned ecu i am not to sure at all when it comes to ecu's anything will help thanks guys. also i did change out the relay twice both fuction properly.

 

infinite possibilities. best bet to start is take very close up detailed pics of both sides of the ecu board so we can try and spot anything wrong. next step would be to send it to someone for testing and repair.
I can do this, or any of the known honda ecu guys can as well like xenocron and phearable.

 

Check and double check (CLOSELY) your 28 pin solder points and J1 jumper.

 

also check IC17
