Why Choose The KnockLink Over Other Products On The Market?

The KnockLink G4 is the only detonation warning device on the market that requires no setup. Other systems require time consuming gain, frequency and noise settings to be adjusted. Without proper knock listening tools, this can prove difficult if not impossible. The KnockLink requires none of this, just wire in and start the engine.

Even light detonation will damage an engine over time. The G4 KnockLink's microprocessor continuously scans the knock signal and warns for any knock occurring. The engine's RPM and load is automatically 3D profiled by the KnockLink, continuously storing and dynamically adjusting this noise profile map while looking for the particular knock frequency.
We recommend connecting the KnockLink to the Link Engine Management knock sensor

Operation is simple. The colour of the LED represents four different modes:
Dim Blue - KnockLink is powered, waiting for the engine to be started
Flashing Blue - KnockLink has detected the engine has started and is now calibrating
Dim Green - KnockLink is adapting to the engine's noise profile and listening for knock
Flashing Red - KnockLink has detected knock. Avoid large throttle openings, seek professional advice

"Great unit guys. Ran mine up today on the dyno and it picked some detonation up that I didn't hear with my ear phones first time power run" Mason Lockyer - Speedworks Dyno Tuning. 

Operation is simple. The colour of the LED represents four different modes:

 

  • Dim Blue - KnockLink is powered, waiting for the engine to be started
  • Flashing Blue - KnockLink has detected the engine has started and is now calibrating
  • Dim Green - KnockLink is adapting to the engine's noise profile and listening for knock
  • Flashing Red - KnockLink has detected knock. Avoid large throttle openings, seek professional advice

    Great watch for the money
    Color: Stainless Mesh/ Blue Dial
    Looks great. I swapped out the band for a leather strap. Nice watch, well designed. My other eco drive has been going strong for 15 years or so without a hitch. So I have high expectations for this one.

    Flimsy, small face
    Color: Stainless Mesh/ Blue Dial
    This watch doesn’t feel like the typical eco drive. The face is small, it’s very light and the mesh band was a pain to clasp. I returned it the day I got it.
