Was reading that the frequency is so different than any other sound, that having false triggers were really not a problem.

Was thinking about this a little, and I agree since the valvetrain on our engines make "clacking" sounds while detonation makes more of a "tinking" sound, which is a higher pitched frequency.

I'm going breather cover and see what happens with fingers crossed.
