93 honda hb CX
I recently put a DX engine, I was wondering if I need to change ECU or would the CX ECU be fine. I can't remember what ECU i got but I think I have the rare one like P09 plus I also tried to put a P05 CX the newer version but it's throwing codes.

 

what kind of engine is it.. do you have obd1 or obd2

 

93 DX

 

You need a P06. Why would you have another ECU in there other than a P05 (the P09 or whatever you have)?

 

YOU CAN ALSO RUN A P2T

 

Except for the fact that his car and engine are OBD1, and the P2T is OBD2. And the fact that the P2T ECU is for the B16A2, when he's trying to run a SOHC non-VTEC 1.5 liter D15B7 engine. So in reality, using a P2T ECU would put him in a worse off position than he is now, even with the mystery OBD1 ECU.

 

i have a dx ecu for a eg let me know if u need it. it came off my dx eg hb. 20 bucks and u pay the shipping

P09 is the stock ECU for the 1st version of CX, then later it came out with P05's

 

WELL IF HES RUNNING A D16Y7 OR Y8 HES MIGHT HAVE TO CONVERT TO A OBD2 I HAVE A 97 CIVIC I HAD A D16Y7 NON VTEC AND THE I GOT A D15B VTEC I HAD TO CONVERT FROM OBD2 TO OBD1 NOW IM RUNNING A P28 ECU
