MoTeC Knock OKM - Manual (Page 17)

MoTeC Configuration 17
Example 3
The car from the previous example has been converted to rally
specifications. This involved fitting a roll cage, larger exhaust etc. Other
than a restrictor the engine remains unchanged.
The knock sensor signal is now concentrated on 12 kHz rather than
13 kHz and the characteristics are different.
In this case a centre frequency of 6 kHz may be more appropriate.

Centre Frequency Setting
After the knock frequency has been assessed and a centre frequency chosen
the Knock Module must be setup accordingly.
For instructions on changing the SKM switch settings, see appendix 1.
Note:
The OKM settings are preconfigured to suit the standard vehicle.
However, should adjustment be required because the vehicle is modified
significantly, contact an authorised MoTeC dealer for further advice.
