    I notice a different KR reading at WOT before the engine hits operating temp vs being already at operating temp.

    Unless they've been changed, knock sensors aren't active until 160F

    When I tune a car, I often bring them down
    I drink..so consider that when reading my posts.

    No $hit, trying to figure out KR so every process is up for review/learning including WOT below 160F - thanks again
