I have made some inquiries amongst friends locally, but no one could give a definitive answer (most didn't even know what a knock sensor was).
so does anyone know?

The car's DME would respond by reducing the ignition timing a bit and altering the fuel curves to try and prevent pre-ignition and/or detonation from occurring. Most noticeable impact would be the car would feel down on power.
