I don't think the 1g does knock retard at all like the 2g. First off, the 1g knock sensor is way less sensitive than the 2g. Secondly, the 2g doesn't keep a sum of raw knock count like the 1g does. There's a "backround" that the ECU uses to determine knock above that level. You're right, 3 occurences of what the ECU regards as knock results in a degree of knock retard. But I think you're looking at 2 different things when comparing instances of knock between a 1g and 2g.

I'm not saying you're wrong, I'm just saying I think it's a bit different. I've never datalogged with a 1g so I can't really comment on that.
