Pfc Knock- Sensor Voltage Correlation?

[maximajim]

We know the PFC knock number is just a number. But we know what's considered harmful. However I have an AEM EMS which reads knock voltage, they do not give a number which can be cosidered harmful. Does anyone know what the voltage to knock number is? Any help is appreciated

Unfortunately the knock sensor is just a microphone, and a voltage isn't really what means it is knock...instead it would be a combination of voltage and frequency which would be knock....which is why a lot of aftermarket ECUs don't bother showing it. In fact AFAIK only the powerFC and standard ECU try to interpret the output into a knock level
