It monitors knock/det in your engine and gives you a numeric representation of it. Handy for mapping and keeping an eye on things when you increase boost, but the numeric value is really just relative and there's no "right" or "wrong" value, it just gives you a good gauge of how likely you are to smash your pistons to bits.
