Porsche sets the knock threshold different on some of the cyclinders - I assume because of the location of the sensor. Hence why your seeing different voltages.

 

quick update: still sorting out some technical difficulties with flashing ability of user mxracer, who was so kind to offer help to make that logger public and maintainable.

update: it turns out that our supporting user has only very limited access to his DME, so the fast logging is not possible.
any other power user here?
to make things clear, my aim is and was to get a "resident" forum user here to make that work on his car and further being able to support other users.

 

wich acess do you need?
