MoTeC's Standalone Knock Module (SKM) provides individual cylinder closed loop knock control allowing tuners to safely optimise high performance ignition maps. The module is compatible with all 'hundred series' ECUs.

The SKM is housed in a robust aluminium casing and can be mounted anywhere in the vehicle. It is wired between the ECU and the OEM fitted knock sensor.

To set up a reliable electronic knock control system it is necessary to determine knock levels accurately and differentiate knock from normal engine noise. MoTeC's Knock Modules use the vehicle's original, factory-fitted knock sensors to detect detonation, improving this detection by reducing the influence of background engine noise using a combination of data gating and frequency filtering.

Configuration of the module requires a competent tuner to carry out a frequency analysis and tune the control system. This is highly specialised work and therefore the MoTeC Knock Modules will only be available through authorised dealers that have undertaken specific training.
