Interesting stuff for sure
Good info just something to keep in mind, KR does not always mean there is/was knock. There are scenarios where knock is likely to occur and the engineers add KR as a preventative measure. You can prevent knock with much less timing retard than it takes to remove it once episode already begun.
Do you have anything to support that? These engines don't require as advanced timing due to more efficient burn.
Direct injection. High compression isn't as much of a worry

My neighbors newer navigator just blew its engine at 120000 miles. Never towed or anything. Pretty sad if you ask me. My daily is a '14 mustang 5.0 and it's pretty alarming. I will say fords engines don't compare to GMs ecotec/lt1 comparing power, reliability, and fuel economy.

There is laziness programmed into the pedal of all these '14s for sure. Definitely wait until 1500 miles to judge the v4 activation. I would not mess with the V4 mode strategy as GM has done their homework with that. Who knows if it is durability reasons like the first gen cylinder deactivation. The 25mi pic i posted is NOT real world, just good to see. Although, the 50mi pic i posted on page three is real world. I can easily get 22mpg will driving mixed but have gotten as low as 18.5 on a tank when some aggressive driving was needed, and when all highway its 23.5. I will say when im on the highway it's cruise control all the time on the highway from 40mph roads to 65-70 mph on major highways..
