It may be picking up some other mechanical noise. Check for anything loos in the engine bay that may be rattling.

ok, I will check it even though I don't think ... and can a slipping drive belt that beeps at higher revs can be the reason? does the map look good?

Hi,
Its not tuned very good... I recommend a new tune.
The fuel mixture is to lean on the boost section so it seems to me the main cause of the knocks...
