Knock calibration

Hi,
Could someone give me a basic explanation on how to set up knock calibration with EMU PRO ?

I fell in the mist …

For the frequency, I have used 1800/(pi x d )

But for the gain ???

What kind of signal level should I aim ???

I have searched for a raw signal input, but seems that it doesn’t exist ?

In fact I am using an original harness with 2 sensors in one connector, and I am unsure wich is N°1 and which is N°2, and I don’t see a way to be sure of that…

Please give me some light on that topic

Kind regards

P.S. excuse me for my poor english :wink:
