You can detect it when it happens because the rods come shooting out of the side of the block 
IIRC, there's nothing in the datalogging program that tells you there is detonation. The knock sensor is not connected on the supercharged engines as the harmonics are too sililar to the noise from the blower.
Watch the a/f ratio, start with conservative timing and if it sounds like it's detonating, shut it down and start again.
