    Default desensitize knock sensors

    to desensitize the knock sensors am i doing this right and is this too much of a change

    i doubled each of the following tables: b6245, b6250 & b6255

    i'm not sure if the car is seeing real knock, it doesn't look saw tooth like. would i be better off to increase the recovery rate? if so, how do i go about doing that?

    What are the burst knock settings at? When is it happening? RPM and DynCylAir reference in spark table? I would try taking a few degrees out where it's happening to see if it goes away. You can also put a few gallons of higher octane gas in to see it goes away. If it does with either of those, it's probably real. I would diagnose this first before playing with recovery rates or sensitivity.
