Tuner Knock Monitor Basic

Looking for the Pro version? visit http://Tunernerd.com

Affordable solution that beats most knock detection gear on the market.

We know how important knock detection is to you. We also know how expensive the tools can be. This is why we created our own tool and decided to share it with the community.

How it works

  • The software takes sound from your knock sensor as a microphone input to your laptop
  • Isolates knock sounds so you hear it over regular engine sounds
  • Displays a waveform with the processed signal showing spikes whenever knock occurs!
