Is my knock sensor on it's way out? High count of knock!

When I first bought my JDM EP3 with JRSC I did some datalogs and found the map to knock for 5 counts around 7.5k revs.
Tuner wouldn't help and had locked map so as I had a spare kpro I did my own map. However while tuning I was finding I could never get my knock count down no more what I tried on ignition so tried original one again and knock count varied from 16-24 counts where as I was only getting 5 before on same map.
I changed the plugs to one step colder incase it was that but no change. Tried retarding ignition from 21 to 18 degrees but if anything it was giving me more counts of knock. Now with this amount of knock I'd certainly feel it but car still pulls like a train.
I've checked my knock level and it never exceeds the threshold on any of the runs.
On a side note, I was that worried bout it I took it to a recent dyno day and asked the tuner to wear det cans while running it. He said he couldn't hear any knock. :?
Any ideas on what it could be?
