I don't know if I understand yr question correctly. But the dashawk reads some ECU parameters through the OBDII port. One of the parameters is knock retard.
I've owned the car for four years now and I've heard it knock about three times (=> highway driving and boosting in sixth gear = high load / low rpm => MZR DISI doesn't like). On every occasion the KR alert on the DH lit up so I figure when there is knock it is detected. However the DH also shows KR on occasions when there is no audible knock (e.g. part thorttle cruising or WOT). I'm not too worried about the part throttle knock, but I'm looking to fight the WOT knock with a WI-system.
