High load cruise knock

im modifying the spark table and under high load cruise rpms, 1200 to 1800 im getting knock. example would be on the high way going up a slight hill, i did not see any knock when it was cooler out say 60-65 degrees, but when it gets warm upper 70s for IAT temps i started seeing knock as much as 6 degrees at times, i pulled timming out twice on my logs but now i have a nasty hole in my spark table. i was thinking of bringing the spark back up for the 60-70 degree temps and then modifying the IAT table to compensate for the increased IAT temps.

side note i think im gonna look in to my MAF table its not as smooth as other tunes i have seen


not using a wideband using the o2 sensors......
