    hi guys, gone to remove my ecu to send of to be checked, iv got the box open but where the wires connect to the ecu itself its like in a little cradle and from what i can see i have to remove this to unplug it, but the only way to do this is to remove the ecu case and undo 2 screws, is the way to do this reallly???????

    ok so i have it removed. i would strongly advise against removing the ecu cover, its sealed on and you cant do sh1te once its off anyway.

    hacksaw blade in the top of the torque bolt thingy and screwdriver the son of a gun. simples

    spoke to the ecu people today and they have said that the ecu fitted does not match the engine and that its for the blb engine which was originally fitted. but my car does run so surely if this was the case the car wouldnt?

    im confused, as the ecu tells the engine what to do? so even if the ecu is different it should adjust for this?

    after all the blb and bkd engines are pretty much the same.

    how would i go about finding out which is the right ecu for that engine?
