    FG Knock Correction Values


    I need some help understanding what the values mean when logging knock correction. At the moment, I have negative values in parts of the rev range. I have read posts saying that this is the ecu adding timing because it is not detecting knock. I have also read other posts saying that newer versions of Hptuners have had this changed and negative values are timing being pulled.

    There is no "KR" being logged in the "Chart vs Time" dialogue. Does this mean there is no knock retard or I don't have it set up properly?

    The car is a 2012 FG six cylinder which has the Spanish Oak ecu. I am using the latest version of Hptuner.
