False Knock Events with KnocksenseMS
I am having a hard time getting my Knocksense to not give false knock indications above 5700 rpm. I already have the pot on the KS board turned down all the way. I found a thread a few days ago that showed how a pot installed in line with the knock sensor could help filter the false knocks out. For the life of me I can’t find the thread again, not even with a Google search. Does anyone have a link to the info or know what pot would be needed and where it goes?
I have MS ignoring knock events above 5700 and it works fine and does not pull any timing, but the continuous flashing light at high rpm makes it useless for identifying when knock is occuring. I am calibrating the knocksense with a detcan and have played around with the timing settings to confirm that I do not have any knock. I keep getting the flashing light above 5700rpm under all different kind of loads as well even <<20kpa coasting so I’m sure it is a false indication.

Knocksense is worth for detecting knock on the short-side of abject failure. It might save you if you accidentally fill-up with 87-octane, but that's about it.
