I have a question...I have a 90 Honda Accord and I'm putting in a F22b1 out of a 94-97 Accord and I still need to get an ECU for it and i don't know if I need to get a 94-95 EX 5 Speed ECU or a 96-97 EX 5 Speed ECU. We're pretty sure the engine is from a 97 accord, and we have a deal right now for an ECU from a 94 Accord for about 15 bux, so any information would be greatly appreciated.

should work just fine

 

If your are sure the engine is from a '97 Accord - this is an OBDII engine. The '94 Accord ECU is OBDI - you will need to get a conversion harness if you want the '94 ECU to work correctly.

DOH! i knew i was hesitant to post my answer for some reason...sorry bro

 

i was told by a guy from hondasociety that the 94 ecu would work perfectly with the car (both obdI) and i wouldnt need any harness or anything

 

94-95 OBDI
96-97 OBDII

engine/ECU cannot be interchanged w/o a conversion harness, end of story

 

wnat some good info?

take the 97 engine drop it into your car, use your stock 1990 harness to hook it all up, get an obd1 distributor, and use the 94-95 vtec ecu.

 

obd1 distributor....so i could just use my own from the f22a1?

Yes.

And v4lu3s is right. As long as you use your STOCK wiring harness and obd1 distributor, it will all work.

Dumb question. But how are you able to tell?

 

I have another question.

I have done some research on this forum and some other forums. I have found out that the 94-95 accord ex P0A ECU is non VTEC. If I was to get the conversion harness and install it on my 96 accord ex vtec, would that have any effect? meaning would that do anything to my vtec or just plain 'ol disable it since the ecu has no function to control the vtec?

My questions might be a bit dumb but I really don't know anything about ECU so please help me understand. Thanks guys.

Look at the ECU is the foolproof way

I was caught out by this as well, mine is a '96 yet is OBD1

Obd1 has 3 plugs leading into the ecu while Obd2 ecus have 4 plugs.
