Also if the ecu is learning the fuel grade, does it also adjust the timing for knock across the rev range? For example it knocks below 3k rpm so keeps the IAM at .7 and then detects no knock above 3500 rpm so advances it to 1 IAM above 3500. Probably a stupid question but, insight would be appreciated. Thanks in advance!

There is more than one method of knock control on a Subaru. There is also FLKC which adjusts it more finely.
