Yup! There is a knock sensor with sensitivity adjustments to match your engine. Then as ping starts it warns you with green LED, then yellow LED then red LED and autible alarms! I have got to get one for tuning!

There's another version that a lot of MS users seem to use, that I believe is much cheaper.
