AED is now tuning all 2011+ Mustangs with Flex Fuel strategy that allows customers to swap between gasoline and E85 seamlessly.

Flex fuel tunes work via Logic based on the front O2 sensors to determine the Ethanol content of fuel after a fill-up of 3 gallons or more.

After an increase of 3 gallons or more is detected the ECU monitors Fuel trims at part throttle between roughly 1000 and 2500RPM.
Based on the Front O2 trim data the ECU will adjust the tune for the new Ethanol blend in the tank.
If you monitor Air Fuel (via factory track pack gauge or aftermarket) you can watch the Stoich change as the ECU learns the Ethanol content.
Once entry conditions for learning are met it will take 10 minutes or less for the ECU to learn the new fuel.

I would love to do it to my 2015😱. What's the price for this?

Custom Flex fuel tunes run $600 flat rate for all motor coyotes. Unlimited time on the dyno when tuning.

Injectors are required as the stock coyote injectors are ~35lb/hr. 15's use the same injectors as the older cars.

Ford Racing LU47's or any of Injector Dynamics units can be used.

What's involved with my 2013 GT500 going this route?

What parts will I need for the conversion?

Injectors, Fuel filter, and BAP.
I recommend the ID1000's or ID1300's
Stainless steel mesh fuel filter in hard anodized housing if aluminum. (we use custom units that fit in the stock location with stock lines)
JMS series 2 BAP with throttle pedal trigger

Wow! Awesome!
How about with a Control Pack? Starting my Coyote swap and I'd love the capability to use a FlexFuel setup!

I've got a Crate Motor Turbo car at the shop I plan on trying it with once it's ready for tuning. Should be a few weeks and I'll know for sure.
