Come to think of it, my brother's MAP wires were reversed too but we caught that before we got it on the road.

P08, a JDM ECU, uses 1-wire O2 and is OBD1. It is the correct ECU for his motor.

Read the previous posts please guys. My D15b is running awesome. I'm using a p08 ECU with a ONE wire o2 sensor which is what its supposed to be paired with. If I had a p28 ECU I'd need a FOUR wire o2 sensor.

All I did was pull the four wires out of the connectors for my 4 wire o2 sensor that my D15b7 utilized and take the one wire I needed and put it in the one wire o2 connector assembly that the D15b uses. Pretty simple guys.
