Ecoboost and E85, Why Not?
Was wondering why the EB doesn't have flex fuel capability. I know of one guy who was running it in his Flex, pumping out 600WHP in the process.

Because the fuel system cannot keep up with the demand which will cause lean conditions. that's about it

Also, from the little I know about ethanol (I've always stayed away from the stuff), I understand that unless your fuel system is designed for ethanol, it can (will?) eat the fuel system seals.
Ethanol is a corn based oxygenator. Corn = sugar. Heated up enough (turbos) can it glaze combustion chamber components?
What I do know is all this ethanol push is because the corn lobby has had their way in Washington. Again, as in many parts of the world (primarily 3rd world countries) fuel competes against food.... and wins (is winning here). Of course, corn, being a grain (sugar) isn't that good for us anyway.

Both answers are pretty on point. We dont have the fuel system to support the E85. E85 needs about 30% more fuel system capacity to run correctly at WOT. EcoBoost F150's also do not have an ethanol sensor either. Because E85 is not always E85 (sometimes blended differently especially in the winter), the PCM cannot adjust for having more or less ethanol on the fly, like a Flex Fuel vehicle can.
Flex Fuel vehicles can read the ethanol content, and bias spark and fueling calculations based on the percent of ethanol.
Will it eat your system seals and stuff, probably not. Even normal pump gas has around 10% ethanol, often referred to as E10. Modern fuel systems like the ones on our trucks are designed to handle ethanol.
Could you tune your truck specifically for E85? Yes. But as mentioned we dont really have the system to support it in WOT conditions. And for doing so you would experience poor fuel economy (normal with E85), and you would have minimal power gains if any with how the truck sits now.
The other fellow making 600+ is probably using a secondary fueling method (port fuel injection, meth injection) to supply additional fuel.

Howdy.
Just to add - you can get an E30 calibration ( home-brew mix of E85 and 93 ) in the 'panty-dropper' tune.

Mixing your own blend of E-LARGER THAN 10 and LESS THAN 85 should be easy if you have an E85 pump local.

Ah never considered fuel delivery. That makes sense then. With proper tuning you can get some damned good power, but not economy, never will get economy.

I don't post much, but when I see stuff like this I have to say something. Most of your statements are false. E85 won't "eat" seals in a fuel system. The fuel paper filter is the main problem, it would need to be switched to a stainless wire mesh filter. E85 won't "glaze" a turbo impeller or combustion chamber. E85 corn is not the same as the corn we eat, and believe it or not our bodies need sugar. However, when you say "from the little I know about ethanol", this is a very correct statement.

Believe all modern cars sensor the amount of ethanol in a gasoline. If u want to crank out more torque tune and add some e85 to the tank say 1/4 of a tank to a full tank of 91 octane. It has higher octane an tune will dump higher mixture of fuel then. The fuels are identical at stoic.
