I think it doesnt really work....unfortunately because it would be not very complicated to make it work like the Phormula one i.e. Let it hear the engine with no knock (set this as baseline) and all the above is knock.

In older 1.1.5x firmwares it was possible to add two additional channels for logging: knock noise and knock value. At least it was very usable to make sure about what you hear in earphones. On some kind of engines it was enough for me to be sure how combustion happen even with no knock listener. Now it seems even knock difference stays 1.0 all the time :(
