So on ECU's that have the ability to proactively work in conjunction with knock sensors to "test" ping and advance timing accordingly, how far will they advance?
From what I've been reading the engine will advance itself if you go from 87 to 93 octane and thus take advantage, like has been stated, but will it go beyond the advanced timing map that's optimal for 93 if you put in 100? It it my understanding that's not part of the program. So while and engine with an adaptive ECU like that of the Camry will see a benefit with 93 over 87, it doesn't appear that it's programed to provide benefit for any octane above that without telling it do so. Is this accurate?
