its not generally a good idea to lower knock sensor settings, unless you know its false knock - which needs det-cans to determine accurately.
have you checked that there is nothing loose or rattling or knocking on the car (like the down pipe? I was had the down pipe hitting the bottom of the oil pan, and it would set the knock light off @ the same area, especially in 5th or 4th gear..
try also checking the knock sensor is screwed in and not loose.
do you have cams at all? (as some cams are noisy) Your timing and fueling look ok in that area (basically stock). Try also taking 1-2 degrees out of the timing in the area and see if its still knocking.
worse case, replace the sensor
- about $100-120 incl from the stealership.
can you post a log of the knock occuring??
