Hi All
I need some help to identify 2 different knock readings.
The first one look like this:

And it apears at around 2600rpm nearly every time.
The second one look like this:

I am seeing both types no matter how I set the ignition 25* or 2* in advance !!! So I am i little stuck here at the moment !
Kind regard. Henrik-ds
