Has anybody figured out how to use the "learned octane" reading yet. I'm still confused. I was using it and it was mostly around 100 as I remember. I kind of demoted it to a second string screen. Turns out my high KR was partially caused by my Sunoco 93 under performing in the octane department. The KR helped me to diagnose and cure the two separate causes but I wonder if I understood how to use the "learned octane" properly if I could monitor the octane kind of tank by tank. Be great to make sure that the 93 you just bought was really 93!
