I have found a ecu in my closet and really don't remember when I gotten it. Anyways,.. this is the weird part.

Its a " 37820-P28-A04 " 92-95 OBD1 Civic Si/Ex BUT it has a OBD2 connectors on it.

you guys have to help me out here,... I dont think it was reprogramed or anything. But I know that you can use a OBD1 P28 on a OBD2 swap...

you guys help me out on this,.... I might need it or just sell it.


Let me know

somebody could have swapped the case so it says P28. easiest way to tell if its obd2 is open it up, from the plugs i'm gonna bet it is a obd2 ecu maybe for a Y8 with a swapped case.

well it look a hell of alot like the P2P in this picture doesn't it. first of all the case for OBD1 and OBD2 are differant, notice there is no screw for the ground on the right side of the plugs liek you would see on a OBD1 ecu and there is the round hole in the side next to the sticker. looks like you have a OBD2 ecu with a p28 sticker on it.
