Can anyone tell me if the wiring is different on the p28ecu from the accord wiring ??

 

what year accord, 1994 I take it probably by looking at your sig? I know to put the p28 in my 1995 p0a car all I had to do was swap 2 wires, a6 (EGR solenoid) and A11 (H02S heater) I think. someone correct me if I am wrong, its been a few years since I did it.

 

Its a 94 accord with a f22B1 i dont even think the dis is right for this motor now.

Its a 94 accord im trying to put a p28 with s300 into the car what has to be done

 

Should be the same as mine then which is also a f22b1 (p0a ecu), swap a6 and a11 for the p28.

 

Ok this is puzzling me. Either my wiring diagrhams are wrong or im too tired lol.

Im beging to think possibly got a bad s300. cause it will not log in . I can up load maps to it but red light still on.

 

Even without swaping the a6 and a11 pins you should still have been able to plug in the p28 with a decent based map for the f22b1 it would have ran but kicked a check engine for egr and o2 heater circuit.

Tell us more about the conditions surrounding your problems with the p28/ s300? Did you rewire anything else when doing this? you running the most current version of smanager? etc? You said you can upload a map, so I would asume your smanager shows online and your not having a usb problem?

Maybe you should go over to the hondata forum or your hondata dealer/ tuner if you dont have any luck here. I certainly dont know a whole lot so I am sorry I cant be more helpful troubleshooting your situation. Maybe some other hondata dealers here can add something.
