Hi Jens
Due not spend time to get the Knock control to work its hard work and I am not sure if its working in firmware 1.1.70.
Use your trimming gun to get the ignition offset correct and use the ignition the safe way i.e. max 25 degrees at high load as a starting point. Get a good starting, cranking, warmup set-up first and play with all the fancy stuff later.
Have you got the engine started?
