Ford first timer.
I totally agree with you, I just wonder if Ford suddenly 'finds' a CPU flash that reprograms our trucks to put out more HP once the Dodge and Chevy crew think they have Ford beat.
Just a thought.
Just a thought.

The only time that would happen is if the competition introduced a higher hp/tq tune in the same year. Ford ain't gonna give away performance if it can sell you a new model year truck. Oh, and the 6.7 flash was in response to GM. Otherwise they would have left it alone.

I think the interesting thing about the graphs is that the bump in HP and torque is from 2000-3000 RPM which is where a lot of spirited driving is done. I personally don't see much above 2000 except when towing and I always use premium then.

First off, he says that anytime you put more than 20 liters of fuel into the vehicle, it will automatically know to learn.
When running reg At 87 the knock sensor retards as high as 3 degrees. On 91, there is no knock retarding to the timing and even advancement of timing and spark.
So in essence, this is a premium engine that has a very sophisticated knock sensor to allow to run at 87.

Gotta run 93. 87 is full retard. Never let your truck go full retard.

So, recently an experiment was done by a driveability tech friend of mine... he had his diagnostic programes running on his toughbook plugged into his truck and ran a tank of regular (or as always) and then premium... both of which I belive he had "flashed" his PCM to ensure it was operating from a learning state. First off, he says that anytime you put more than 20 liters of fuel into the vehicle, it will automatically know to learn. When running reg At 87 the knock sensor retards as high as 3 degrees.

Curious if the truck can adjust to exceed 91.

I was always told the only engines that actually need or would benefit from higher octane fuel where those which have higher compression ratio’s….which I was of the impression that EB engines do…? Maybe I’m mistaken or that has changed. Either way, with all the adaptive characteristics I guess it doesn’t matter anymore, if running low octane the ECU just adjusts to prevent detonation until the proper fuel is used but I still want to hear a MUCH MORE trustworthy explanation of how exactly higher octane fuel in a standard compression engine provides for increased mileage or actual increased horsepower other than “Ford said so”…

We discuss fuel and octane ALL THE TIME yet this one from 8 years ago is the one you found vs anything from last week. LOL
