D15 ecu trouble, Please help...

[Mal]

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.

should be a 5 speed. a51 or a52 usually are auto ecu. a00 and a01 are usually 5 speed ecu.

did you jump the svc connector to see what code it's throwing?

Its throwing 41 Primary oxygen sensor heater
Though Im pretty sure that wouldnt be what's causing the hesitation

Ah, seems the Cx only uses a 1 wire 02 sensor while everone else uses the 4wire. Lack of proper 02 voltage would definately cause the engine the engine to bog at take off. Guess I'm doing some rewiring....Thanks all
