I do believe you that the MSS60 can individually control spark timing in each of the 8 cylinders, however if 1 cylinder consistantly had knock I am sure the DME would eventually pull timing straight across the board. No?
DME doesn't have free reign to pull any amount of timing that it wants. It's restricted in the amount of retard by the code, although this can be modified in the calibration. If one cylinder had consistent knock, the car would certainly throw a fault. If there was bad knock detected it would throw the car into limp mode after a certain amount of occurences. To my knowledge, The supercharged cars have misfire detection turned off or they would be throwing multiple fault codes.

OP: Glad you got it sorted out!
