The ecu uses some calculation to look at fbkc and flkc to determine when it will drop iam or increase iam. It apoears to look at the magnitude of the knock and the frequency and duration of the events. You can get the odd spike of say -2 flkc and not drop iam but if you get repeated events of even -0.6 in quick sucession it may drop iam.
It then looks for knock free or minimal knock passes through the rpm load areas where its seen knock events previpously to determine if it will increase iam.
you can often get your iam back to 1 by doing a number of light steady throttle say 15% throttle runs in second or third from 2000 to 5500 or so. At light loadsecu wont see knock and will increment iam back towards one
