if you have tried removing advance from all maps and still have a knock i would suspect carbon build-up on the pistons igniting the mixture esp. if this happens when the car has been running for a while. hope this helps

when the car is idling in closed loop is the fuel being injected and the timing settings based on the calibration loaded or is it a different map?
i'm getting misfire codes (all cylinders) and the engine shakes slightly, it also has an intermittant "thump" through the exhaust.
