Can anyone help?

I do not appear to be getting any knock correction from the AFO41 ECU fitted to my car STI 5.with SECS monitoring unit.

I have renewed the sensor to no avail.

This is causing the knocklink to flutter more than I would like.

Could it be cable fault?

What do I check?

 

Checked continuity from sensor conection Blue/white stripe. To
same coloured wire on ECU plug . No joy

Have I checked right?
Is this the correct pin?

Is it knacked wiring?
