How much of this phantom knock is related to the rattly clutch spring phenonomen JohnBradley posted about recently?
Steve Knight (South Australian EVO racer/tuner) mentioned he has been patching the values of timing pulled on knock for some time now, to good effect.

going from stock clutch to exedy twin didn't add any knock for me, then I did the tubular header and it began, I changed to the tilton twin carbon and it didn't worsen. I went to the BR 2.0 and I THINK it may be slightly worse, the tone of the car definitely changed.

i still have my balance shafts also
just now i replaced my gutted br cat with a second bullet muffler and it seems that the phantom knock quieted down a little bit, its still most definitely there though
I cant wait for this patch to be done

I often get shift knock or knock when using the two step and launching.
I think these issues could be addressed if a load & RPM limit were implemented for knock control. However, you might have to make the load and RPM cutoff pretty high to avoid 2-step knock.
What about making it so that when the clutch is depressed knock control is turned off. That seems like the simplest way to ensure no knock during shifts or two step without having to make an artificially high load cutoff for knock control.
