A pro racer told me that he installs a plug three heat ranges colder in #5. This tends to confim that it's not engine noise that causes the activity seen.

If for some reason the link doesn't work, google "knock controller demo".
How does it detect each cylinder? Does it use one sensor or one per cylinder?
