The Gizzmo Kmon is a complete audio monitoring kit for accurate listening for engine knock. The Gizzmo Kmon will help take your tuning to the next level. The Kmon was designed with leading tuners for tuners with endless hours of dyno development as a major component in the research and development process. Each headphone can independently be configured via the software to listen to different knock sensors e.g. on a RB26DETT you could configure the left headphone to the front of the motor and the right headphone to the sensor on the rear of the motor or on the V8 one sensor could be used for the right bank and another for the left bank (please note that there Kmon comes with one sensor and sensor loom). There are two headphone jacks for the convenience of training a tuner or a second set of ears when tuning.

The knock sensors used for the Gizzmo Kmon are the Bosch donut type that allow a 10mm threaded bolt through the centre for easy mounting. The software allows you to tailor the knock channels individually to the motor in addition to setting up the headphones as you desire. It is also possible to set the headphones up so that they are silent until a warning threshold is reached e.g. you can set a warning level of 60% and if this threshold it exceeding the headphones will emit a loud, sharp buzz. After the software has been configured you can shut down the software and just plug in the Gizzmo Kmon (to a USB2 port) whenever you need it; the Gizzmo Kmon will always just return to your settings very time it is plugged in. The Kmon also has two analogue outputs so that you can log the knock levels into a dyno for comparisons against air fuel ratioï¾’s, boost etc. On the side of the Kmon are 4 LEDï¾’s; one indicates power, one flashes showing communications and 2 ultra bright LEDï¾’s illuminate if the knock threshold (previously explained) has been exceeded. Internally thing the Kmon is armed with 5 processors. 2 are 20mhz DSP processors (1 per knock channel), 2 are 48mhz RISC processors for number crunching, control and communications and the last processor is just for timing alignment.


Knock detection is critical when tuning for performance. Attempting to modify the fuel & timing parameters without monitoring for cylinder detonation & pre-ignition is asking for trouble, serious trouble. The Kmon Knock Monitoring system by GiZZMO Electronics is professional grade knock monitoring equipment. With the optional second channel kit, you can add knock sensors to additional parts of the engine to monitor front and rear or left and right banks, etc.
