    What year is the vehicle? Does it have the correct loom to suit the ecu or is that what is wrong.

    If you have a rev1 ecu on a rev2 loom then either buy a conversion harness or repin the plugs to suit the ecu.

    So if its a rev 1, does it have a rev 1 ecu and loom? All rev1/2 sw20 came with a gen2 3s engine.

    Here's a picture of my ECU. 
     

     
    Note that the part number 89661-17280 is the same but the OEM reference number is different 175700-2302.
     
    My ECU is out of a TYPE I (JDM) SW20 G-Limited with a Generation II 3S-GE.
     
    I'll see if I can find any info on your ECU.

    Would your ECU by any chance happen to be one fitted to UK based 3S-GE powered SW20's? I did a quick google search and they all seem to be UK based sites.
