Interesting. I never knew procede did knock control on itself. The only way I would imagine you prove it is using a high octane map and running low octane. Then run a Bavarian tech for CAN interference or even knock on certain cylinders. If there is no knock present it means the procede did its job. Same thing can be done with the timing.
