The knock sensor is a piezo-electric sensor that is tuned to the exact sound of detonation in your engine. It shuts off as it climbs over 6k rpm not because it loses performance, but because normal engine sounds begin mimicking knock at that rpm. It's a resonance thing. If you ran your car to 10k rpm, your knock sensor would work fine from around 7500-redline.
