i did try disconnecting the knock sensor but it had no effect. does the ecu assume the sensor is faulty and run in LOS mode if it's disconnected? if it does then it could well be the knock sensor. does anybody have a spare knock sensor or series 1 ecu(no knock sensor facility) i could try in the north west? thanks ray

does anyone know if a series 2 chip will work in a series 1 ecu????
