Assuming there is already an ADC for knock detection on board why can't you stream the filtered and/or prefiltered audio to the PC?

This will make checking and setting up the knock settings without needing to plug an external knock sensor and/or extra equipment. Knock audio function is already there.

Of course this requires some bandwidth (not really much see below) but USB 3.0 or disabling logging channels to the rescue.

For 32khz mono 16bit = 32000 * 16 * 1 = 512 kbps or 64 KB/s which is not much

If the electronics required don't exist on current ECU's (i don't know about G4X, i only have G4+) you may consider implementing it in the future.

Kind regards
