I have a 1996 Civic with a P-28 ECU chipped with a Hondata S-100. As of today it has decided to run like absolute ****, and the check engine light stays on. I know with a stock ECU I can use a jumper in a little connector under the dash and it will flash the check engine light to tell me what's wrong. I am wondering if the same process applies for the Hondata, and what codes do I use, the ones for a P-28?


Please help, I am about to drive the damn car off a dock if it doesn't start running right.

 

BTW: the nearest Hondata dealer is three hours away, car won't make it.
