The ECU will pull and add timing per cylinder if in this mode so all 6 cylinders can be running different timing.
the ecu also adds timing until it hits a timing limiter (combustion pressure limit, LSPI limit, or MBT) or a limit of how much advance it can add (under the knock tables based on load and RPM). You can look at an individual cylinder's timing and timing correction and see how they relate to each other in a log. A sharp drop in ign corr is usually knock were as a more squigly drop is usually bumping up against a timing limiter.
yea popcorn is LSPI as others have stated. The low medium and high load limits for LSPI are going to be based on your OAR (or KOM for the new cars). Depending where the KOM/OAR is its going to blend tables between low/mid/high. Borderline timing also has a modifier based on OAR/KOM.
