    Default Honda City 2002 ECU pinouts

    Hello guys. Faced a severe issue in my car couple of days ago. It got stalled on the way back home and doesn't start. On inspection from workshop, it gets identified that the ECU got busted, as installing the new ECU removed all the issues. Anyways, I am still bit skeptical on this finding. I have the faulty ecu with me. Just wondering if you guys can share the ECU's pinouts/ schematic. I got technical background, I will try to fix the issue. Thanks

    if you are using 1.3 ecu then your system is going to be lean means less fuel more air and timing difference will also occur.

    u should also chek for injectors whether they are usable for 1.5 or not . if injector size is smaller then less fuel will b injected.

    best solution try to find pakistani city 1.5 ecu that came in my city 99 1.5 . its model is P3S-K01 if you find different ecu with the same pinout and harness it can also be an easy ecu swap. wiring is same everything is same just it is designed for 1.5 .

    i also swapped engine from 1.5 to 1.4 and problem was occuring just fuel mileage decrease fron 18km/l to 12km/l on highway

    there is another solution . find some efi specialist who can modify ecu software/map... he will add map of 1.5 in your ecu . but u have to verify by asking the specialist whether your ecu can remap to 1.5 ecu map
