Switch it to peak hold and look at the number it gives you. If you see anything above 70 it is probably bad and knocking. But every FD is different and depending on how good or well mounted your knock sensor is will affect the number.

Search in the PFC section and you will find some knock values that othes see and have seen. This will better give you an idea as to if your numbers are good or bad.

This could be moved or should have been started in the PFC section.
