The PCM modifies timing to curb power output when the knock sensor fires. This indicates detonation is occurring, and the PCM will retard timing (and power output) to prevent it. But it only does this at high power demand. There's no advantage to changing timing at lower power demand when...

Agreed! That depends on how you define "significant." I saw no significant difference in my testing (all data posted at the link I provided), but others have claimed otherwise. I've seen some claim they get 28 mpg with E10 and 32 mpg with ethanol-free premium. I question data like this mainly...

I believe part of the decrease you see is related to formulation, but it's also related to the temperature. Ford's EcoBoost engines run very rich while the engine is warming up to get the catalytic converter up to temperature as rapidly as possible. The more short trips in the cold, especially...

Hand computation on a single tank is not sufficient--there are too many variables. The only way to get an accurate comparison is over several tankfuls. The Owner's Manuals for Ford's EcoBoost Mustang and Bronco Sport say to get accurate hand measurements you should track miles over at least...

If the Maverick works like other C2 platform vehicles (Bronco Sport, Escape), yes it does. Aside from changing throttle response, these modes affect transmission shift points, and steering feel.

I'll believe the performance gains when I see an independent test. Turbocharged cars don't typically benefit much from filter replacement, and the stock intake is already pulling from the grill area, so I don't see how it's going to get much colder. My biggest beef with K&N isn't the limited...

This Ford advertisement probably didn't endear it to cat fans.

Sort of. A manufacturer can deny a warranty claim at any time for any reason. It's then up to the owner to dispute the claim denial. Then there is a long, convoluted process to sort out the differing claims including mandatory arbitration. The law imposes penalties on manufacturers that falsely...

Which means COLD weather. Do you do many short trips with a cold engine? I don't believe any of those factors has as much influence as ambient temperature. EcoBoost engines are notorious for running rich when the engine is cold. If you make a lot of short trips around town before the engine...

Good writeup. One nit to pick: The manual says nothing about fuel economy in the section regarding fuel quality. Here's the exact quote: There is no significant difference in energy content--usually measured as BTUs--between regular and premium gasoline. Higher octane fuel requires greater...

Where in IL are you? PM if you don't want that public.
