j&s safeguard problems..

[Eggroll]

So I installed my J&S safeguard v2 but I can't register any knocking even when I set it to max sensitive. Having it set to max sensitive, should it retard knocking when revving it in neutral? Also what kind of volt does the knock sensor give out? Does it give out a signal even though the stock honda ecu doesn't do anything about it (as in the volt is so low that ecu does do it's own knock retarding...). FYI I drive a 99 base lude. Any help would be greatful!!!
