PLEX Tuning tips - 5 TIPS FOR INSTALLING A KNOCK SENSOR THAT EVERYONE SHOULD APPLY 1. Always prefer the original mounting position as used by the OEM If not available then find the next best position following the order of preference as indicated by this diagram. 2. The mounting surface must be machined flat and square to the threaded hole or stud. It must also be at least 22mm in diameter. Why is that? Because a proper contact surface will ensure that the engine vibration will be transfered to the sensor reliably. 3. When installed, ONLY the center metal part of the sensor should make contact with the engine 4. Make sure that the sensor mounting bolt or nut is torqued to the correct specification The common M8 thread requires 20Nm torque. 5. Secure the knock sensor cable a few cm away from the sensor to prevent unwanted vibrations being transfered to the sensor If any of the above is not adhered to, the acoustical coupling of the sensor to the engine will be compromised and the output signal of the sensor will not be reliable for knock detection!
