I recently purchased an OKM to retrofit to a WRX9-10 board. Default jumper settings are as follows:

Differential Mode Switch = off; normal knock sensor connection (default)
Gain = 2 (default)
Knock Centre Frequency = 10 kHz (default)

Could you please provide the correct default jumper settings for the following application:

06-07 Subaru WRX STI w/EJ257 (2.5L, single AVCS) motor

Motor is completely stock internally, with only minor external modifications (open exhaust, panel air filter).

Use 14Khz for the knock frequency. Then read the SKM/OKM user manual, it has detailed instruction on how to use the SKM/OKM

14kHz - thank you.

Do you know the default gain jumper setting?

I have read the OKM/SKM manual cover-to-cover three times, and I'm just trying to start with the same baseline that this board would ship with for my application.

Most OEM sensors work with the standard gain settings so no need to change them.
