Correct, octane adjust is there in case you get a tank of crap fuel. It has nothing to do with the learning process of the tune. The OEM calibration goes through a learning process as well. It is just how the ecoboost cars work.
The "OAR" function most certainly can be turned on or off in the procal tune. By default it is off. Which as far as I can tell just sets the OAR to -1 (best gas).
With OAR off I was unable to get any data from the 3 or so knock sensors during logging. I have since turned it on, and that data can be observed.
