KnockLink is a self-calibrating, visual knock warning tool. The KnockLink is designed for tuning, street and race use. Will require a knock sensor to function (sold separately) or you can purchase the KnockLink Kit that includes the Knock Sensor and Loom.

The G4 KnockLink 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.

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

    I worked with Mike Drexel on a remote tune for my ‘97 Miata with MS3 and a mildly build NA motor. I drove my <500 mile built motor 6hrs to tail of the dragon on MS3 basemap, he got me booked for a remote tune in the morning the next day and even with not the best internet connection he got me sorted within 7 logs and it drove phenomenally well the entire rest of the week I was down there. Good power, Always started hot or cold, idled well, fans or accessories didn’t kill it at idle and it was over all very smooth even when getting stuck behind Harleys going 5mph on dragon. Cannot thank him enough.

    My project was to Megasquirt swap a 1998 Suzuki Carry Kei Truck. I installed a GT15 turbo, LS2 coils, Subaru STI injectors, and many other modifications.I learned about Mike from a Megasquirt Facebook group I was in. I originally didn’t listen to his advice, and decided to try and diagnose and tune everything myself. After spending days trying to figure out the issue, I decided to throw in the towel and reach back out to Mike.Mike worked remotely with me tirelessly through the night to rectify the issues I was having with this one-off install. Mike is an absolute wizard with diagnosing and tuning. From the first tune file I could tell Mike was on a level that my previous tuners were not. His response time is incredibly fast for the work he does, and he’s very patient, even with my thousand questions. When we finished with the 93 octane tune I was so impressed that I made the call to go ahead and tune on e85. After a few more revisions we had a completed 93 octane and e85 tune. This further gained power, and truly made the truck how I wanted it to feel from the time I started the build. Mike is a master of his craft, and he will be my tuner from here on out.
