    Engine knock

    I have an engine knock question.
    When data logging feedback knock is always 0, the fine knock learn mostly 0 but at its peak in one log it was -175.
    And in another log o to -1.40. Trying to see if in tolerance.
    This was done in 3rd gear from 2,000 RPMs to 6,000 rpm. I haven't figured out how to post them but I can email them.
    Any opinions or advice would be appreciated, I am new to logging.

    Where is the knocking occurring? In what rpm range and at what throttle percentage.
