Im putting a d16z6 into a 1990 civic lx with dpfi. I know how to do the dpfi to mpfi using a si ecu but i'm using a p28 ecu. I cant find any info on if the pin out is the same or if its different. Can anyone help me? I'm trying not to break down and take it to a shop but im getting close to doin it. Please help!!

 

no its different. a p28 is an OBD-1 ecu

 

if your going to be using a p28, then your obd-1
the pins for that are

vtec solenoid - A4

vtec pressure - D6
- the black wire is ground

 

Thanks for the v-tec pin out. So the injector pin out on a p28 is the same as a pm6 si ecu? I know a p28 is a obd1 ecu and i got a obd0 to obd1 jumper harness. That wiring is no problem. I just don't know what pin is for injector 1, injector2, etc, etc on a p28. So if they are the same like i was just told then I could just follow a right up on dpfi to mpfi right?

 

1. CONNECT THE YELLOW WIRE FROM THE DX INJECTOR TO THE #1 INJECTOR(BROWN WIRE)
2. CONNECT THE RED WIRE FROM THE DX INJECTOR AND RUN IT TO THE #3 INJECTOR(BLUE WIRE)
3. CONNECT THE A3 WIRE FROM THE ECU(PLUG A 18 PIN) THAT YOU WILL INSTALL TO INJECTOR #2 (RED WIRE)
4. CONNECT THE A7 WIRE FROM THE ECU TO INJECTOR #4(YELLOW WIRE)
5. CONNECT THE 4 RED/BLACK WIRES FROM THE INJECTOR RESISTER BOX TO EACH INJECTOR.
6. FOR THE P28 ECU JUST GET A JUMP HARNESS FROM OBDO TO OBD1 AND THATS IT. WIRE ALL THE ABOVE TO THE CAR HARNESS AND THEN USE THE JUNPER HARNESS. DID ONE OF THESE SWAP ALREADY. EMAIL ME WITH ANY QUESTIONS AT CASTUDILLO01@AOL.COM
