Hey, Ive got a 93 cx that I put a D15b (non v-tec) into. I just got the proper ecu today (P06) but, when I put it in, it throws the service light and has a huge hesitation whenever you step on the gas. Im sure timing is correct and it runs well with the old P05, so the engine is fine. The person I bought it from assured me that it was from a 5 speed and it works but I dont know my honda codes



Can anyone identify from the code there if it is indeed a 5 speed ecu?
Any help anyone can provide would be greatly appreciated.

 

Not that anyone responded or anything but I figured it out and for future reference to anyone who might run into the same problem; the CX D15B8 uses a 1-wire O2 sensor while everyone else uses a 4-wire, hence the hesitation and the code 41 it was throwing.

 

Glad to see you got it resolved

 

good job
