Its the PLX R500, Looks pretty nice, but i was wondering if it sees knock on 2gs.

It would see knock the same way the newer S-AFC2s see knock. Also somewhat similar to the way you see knock in the AEM EMS. It isn't anything like the simple, cut and dried kind of knock reports you get from something like a 1G datalogger or DSMLink.
