Did you check to see what code the ecu was throwing?

i am checking the codes by the way the book says to do it, but my srs light just flashes.

Somethings probly plugged up to the ecu that doenst need to be. U should check to see if the knock sensor is plugged up, the p28 doesnt call for it. Did u check ur 02 sensor to make shure the connection is good. My friend didnt solder his up and now its throwing that code. Those are the only two things i can think of that could make the light come on after the ecu swap.

i unplugged the wire for the knock sensor and it still was on. And once i put the p30 back on the check engine light goes off. With the key in the on postion the check engine goes out for the p30 but not for the p28.

Damn, I have heard this exact same thing before, but I am spacing on where. Are you sure you are jumping the right one? In my civic there are two right next to each other.

the picture in the manual looks like the wire i using. so i don't know.

there could be a couple of things, one the p28 could be an auto ecu, and two do you have a single wire o2 in the car or a 4 wire o2
