IAM is driven by the knock sensor and resets after a engine shutdown/startup cycle. I normally use that as a determining factor as to whether there is significant amounts of knock currently.
KC learned I believe is persistent across engine shutdown/startup, so those values indicate regions where it has detected knock from sometime between the last time you flashed and now. This indicates that your engine is already reducing timing in that region.
So with IAM at 1, and KC Learned at some value, it shows that your engine is not currently knocking, but has knocked at some point in the past.
