Yes, but the PFC doesnt do anything about it, so unless you hear knock and keep into it whilst looking at the hand controller, or watch the hand controller whilst the car is driving, its not really much good unless you have datalogit. If you are running stock cams, there is no reason to go single throttle, the d-jetro will run it fine, just hook the map sensors up exactly as the instructions say.
You don't have to be looking at the power FC controler to see if there is any knock, if the reading goes over 60 it flashes the "Engine check" light.
