the ECU is also quite agressive in removing timing and will often remove double what is needed to supress knock.
You can get a better result, smoother running and more power by tailoring the ignition advance to your fuel rarther than letting the ecu do it.

I seem to have plenty of knock and I'm on stage 1 tune, so if you're able to correct it then you should. Unfortunately I don't really know what I'm doing...
