E85 flex tune for 350

[KGTG350]

Since there is only one station offering e85 locally I was hesitant to order the tune given the low price of gas and possibly uncertain future of ethanol. I wrote to Propel Fuels and this is what they told me:
"First off, thanks so much for reaching out to Propel. We always love hearing from customers interested in learning more about our fuels. Also no need to worry of Propel going away anytime soon in fact you'll begin to see more locations carrying E85 than before. In 2015 we had our best year ever and will be expanding Propel fuel points across greater California

We know our customers expect a true E85 product, so we do our best to hit that mark. That said, we strive to offer E85 that is as close to 85% percent ethanol content as possible (with a typical delivery containing between 82% and 84% ethanol). And, because the weather in CA doesn't vary as drastically as it does in other parts of the U.S., we offer that blend year-round."

Encouraging.

That is good news thank you for sharing.

I've got at least 2-3 gas stations within 20 miles of me carrying E85. If I ever switch it should be pretty convenient.

Wonder if running E85 will have negative effects on the engine over time. I'm sure I can do some research online and find out.

Anyone running e85 currently that can give us their personal experience with it on a daily driver stand point?

Below is also an interesting link. You can enter any combination of e85 and pump gas and see what the resulting e% and octane would be. Also of note is the fact that to create e85 they actually add ethanol to 87 octane petrol. Straight e85 is 105 octane which is likely a lot more than most guys would need for daily driving. A 50:50 mixture of e85 and 87 yields 96 octane which is still plenty stout if one is concerned about saving a few bucks.

Updates ?

My Ngauge arrives tomorrow so I will report my findings soon.

What link

I'm installing my flex fuel tune from Lund today. I'm going to burn as much as my gas as I can before filling with e85. I'll report back later tonight.

Say, how long did it take you to load the tune file onto your Ngauge? I received mine today. It has been loading for over an hour and is at 58%. It says it is loading 657 files.

The first time I think it downloads stock, but even then its like 8-10 minutes. I would definitely contact lund however. Hopefully it completes. Dont forget to keep a copy of your stock tune.

Do you have a notebook or anything else connected that might be slowing the processing?

With a factory tune that will capitalize on race gas, keep a drum in the garage, keep your warranty and likely get the same gain.......27 rwhp and 27 rwtq running 98 over 91 ;)

Has this been confirmed, I have heard it said, but never seen anything that proves the stock tune has timing and fuel maps that will take advantage of fuel over 93 Octane. Seems too risky for ford to make the tune more aggressive than that which was tested and used in R&D.

I discovered that I was downloading the entire email, not just the tune file.

I have yet to run E85 in mine, what I have run is torco octane booster. It's a real octane booster and not like the crap at the auto parts stores. I have noticed it pulls harder wot then with 93 in the take and it's cheaper then true race gas. I've run 5 gallons of 93 and one 32oz can of torco and it will raise your octane up to 4-14 points depending on ratio. I bought 6 32oz cans from Amazon

I bought one can to try, but it is also available in a 5 gallon container, brings the price down quite a bit.

Correct on the 5 gallon pail but I figured I'd try it before purchasing a 5 gallon pail. I just bought a 2016 f150 regular cab short bed with the dwarf 2.7 Eco boost. I'll use it in this also lol.

Would be interesting to do before and after dyno pulls and pump and then with Torco added.

Sure thing

I wouldn't post something like that without data to support it. A friend of mine dynoed it with 91, 93 and 98.
