I have a flex fuel tune, and switch from E85 and 92 octane from time to time. E85 allows more spark advance, which will wake the car up across the entire RPM band. I notice a difference in power, but I feel that drivability and start up is better on pump gas where I live. I use E85 when I want to beat on the car a little bit, and having the detonation protection is a great piece of mind. It is one of the cheaper mods to do, since all you need is injectors and a tune revision.
Sure, there are more gains to be had with E85 and boost; however, you're going to want to squeeze every bit of power out of your setup if you stay NA too.

E85 flex tune you should take it in a heart beat then find out at what % gives you the best of both worlds on NA I think around 40% concentration of ethanol is good but that was on a non variable cam motor. I Think it depends on the tuner and gains at what percentage of ethanol concentration but I don't know if there is enough R&D with the coyote motor. My example was on c6 z06 on the dyno with multiple concentrations of ethanol and dyno pulls plus real world datalogs ie driving.
Get a flex fuel tune if you don't think it's worth it run 93.
I contacted AED about the flex fuel tune. How do you like yours? And which injectors did you get?

lose the cats and run the e-85 = about 20rwhp combining the 2 mods and no stink from not having the cats on= win win.
I don't think that flex fuel tunes have as much timing advance, hence less power gains.
I absolutely love it. I love that my wife can throw 92 in the tank if she ever runs herself out of E85 on the road. It is kind of cool to watch the stoich value change between tanks (14.1 down to the 9s). Shaun will mandate the use of 47# injectors, I recommend the Ford Racing LU47s (about $250). Get the AED tune, tell Shaun I sent ya lol.
That should be with the boosted applications. The "flexfuel" tune runs less timing for safety concerns, and the "race" tune is for E85 only. NA flexfuel should be constant timing.
Alright, already contacted Shaun! And will my car run fine everyday with the E85? That's the only thing I am worried about because it is my daily driver and don't want anything crapping out on me bc of the E85.
Cold starts on e85 sucks, you can make them better by adjusting your start up lambda and spark, but sometimes it can be annoying. I keep my mix to e47 and have zero issues. If you have long tubes you may burn out the 02 heaters faster than if you had stock headers.
I have had driveability issues in general with e85 but it wasnt always like that. I think we have a shitty tank of e85. Switching to pump gas fixed everything.
Was it only one time? Or was it consistent driveability issues?
Not constant. The e85 pump is on an army post, and fuel quality can be iffy. Thinkin its a bad tank
Oh
ok. Thanks for the info!
If anyone needs a set of LU47s I have a set that I swapped out in July for my ID1000s Id be willing to sell and ship. PM me.
