Any one montioring the factory Knock sensor signal? I know the S-AFC II allows you to monitor the knock sensor.

I'm watching it via the external signal harness on my Profec e-01. All i'm getting is .12 volt no matter what the car is doing. While I'd like to believe that I'm not seeing any knock there should be some low level activity.

If any one wants to check it out it's Pin 15 in the ECU harness. It's a white wire. The service manual says it should have 2.5v on it at idle but mine does not.

Thanks for any feed back
