E85 tune?

[Blue87GT]

Anyone have a canned tune for running E85? Interested in both the cheaper fuel, and increased power that can be had with it.

There are NO canned tunes for E85.

There is only one Tuner I know of writing Stock Pump/E85 tunes for the 4th Gen Expedition and that is ZFG.

Our 2020 runs it daily.

Here is proof of our last fillup for the doubters, and Dragy of it 0-60.

This is a 2020, Max, Limited(Fully Optioned) on factory 22’s. Your MPG WILL go down.

E85 fuel has less energy per gallon, when compared to conventional gasoline: https://afdc.energy.gov/fuels/ethanol_benefits.html

As such, when using E85 fuel - you will see a reduction in your miles-per-gallon (compared to conventional gasoline).

That's impressive @LokiWolf

Do you have aftermarket high and low pressure fuel pumps?

I sometimes run an effective e25 blend with my JB4 and 26psi boost (Raptor engine in a Navigator), and that's as high as I can go because my fuel rail pressure drops dangerously low (to the point where afrs might be affected if I keep my foot on it).

Yes, and mentioned that above. The cost saving at least where I am is more than the %MPG loss. Not to mention the power gain.

Nothing added. Just E85 in the tank, and ZFG’s E85(Stock Hardware) tune loaded.

That is a few revisions in. The baseline is VERY safe and it is dialed in from there.

Yeah, if the JB4 is designed for Pump Gasoline then it will not be able to adjust for Higher Ethanol levels.

I could actually get MORE power out of E50 than E85 with stock hardware, but then the wife would have to mix. It would probably be good for about 2 10ths.

Thanks for the company name, I'll search them up. Fully aware of the reduced MPG-running it in my 2003 Cobra and 2014 Merc.

DAMN good 0-60 numbers!

He is not accepting new customers right now, but will be soon. He has a waiting list on his website. Well worth the wait!

BTW
Ethanol is a carbon neutral fuel
When it is consumed a certain amount of carbon is released into the atmosphere
However when the plants are grown that are used to make it they remove an equal amount of carbon from the atmosphere
That is why it is carbon neutral
Ethanol has an octane rating of 113
E85 is about 108 octane
Usually the loss in mileage is offset by the lower cost of the fuel when compared to premium gasoline

Can I deduce, our stock fuel pumps are safe to use E85?
