I thought this new dyno with the eddy current was supposed to fix the false knock issue.. something smells awfully fishy.

Resonance is resonance...Eddy load controlled or inertia style would not matter. Having been involved with tuning on the LFX cars, I have seen false knock on a near factory vehicle and on supercharged one. However, after working with the knock sensor charts, by logging and analyzing data (Not just removing them!!) we can scale back the knock sensors to allow for resonance due to modifications that may set off factory sensors (Such as headers, superchargers, etc.).
However, that false knock really would not be due to a dyno, these knock sensors are a lot further sophisticated than the older KR sensors. Heck the turbo buick sensors were garbage, the LS1 044 ECU sensors were damn good, and everything in the newer "Exx" ECU's seems to be quite good. I do not have any experience tuning the LLT's, but I would have thought that the tune would compensate for any false knock, and it's not just going to show up due to a load control dyno.
Oh and the only reason for my two cents here is because I was contracted as the outside dyno shop, and if there is questions to our dyno I will happily answer anything related to it.
