throw this in the tuning section as they will read it better than in 'evo general'

have you tried putting in high octane gas to see if its mechanical or true knock?

Knock sensors can read other things as knock, too. Have you made sure your exhaust is away from everything, and that it's true knock? Like, if you log without going into boost, is it still knocking past 3K? It also looks like you went way lean(18+) at log id 27.

* Note, I'm not that familiar with reading logs; the tuning forums, as suggested, will probably be a better place.

Are you logging knock voltage? This will help you differentiate between real and phantom knock. And you didn't specify as to when the car knocks. WOT? Part throttle?
