MoTeC's Onboard Knock Module (OKM) enables individual cylinder closed loop knock control on our M800 Plug-In ECUs. The knock module allows tuners to safely optimise high performance ignition maps.

The OKM is fitted onto the board of a Plug-In ECU prior to delivery and linked to the knock sensor. M800 Plug-In ECUs are available for selected Subaru, Mitsubishi and Proton vehicles.

The OKM is preconfigured to suit the standard vehicle. If the vehicle is modified significantly, contact an authorised MoTeC dealer for further advice.

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.

Knock control tuning is highly specialised work and therefore the Knock Modules will only be available through authorised dealers that have undertaken specific training.
