is there no way around the knock sensor or will i have to try wire one in? do u think i could take the chip out of the S2 ecu and put it in the S1 ecu? or would that never work?
thanks for your help mate

Nope you cant swap the chip over it wont work. Problem is your loom doesnt have the wiring for a knock sensor so you cant just plug one in, might be easier to get a S1 ECU or an early S2 ECU (no knock sensor) thats chipped.
ECU Colour Codes:
Blue-Red-Blue S1
Blue-Red-White Early S2 (No knock sensor)
Blue-Red-Black Late S2 (Knock sensor)
Hearts & Diamonds 90Spec (knock Sensor)
