5.0 + E85 Fuel

[robry]

Actually there are a few tuners offering N/A flex fuel tunes on e85, but it’s unnecessary if a good tuner know show to adjust the logic. OZ offers 1 tune for all fuel with max timing being about 34 degrees under WOT. Stock, max timing is around 28. I can achieve these numbers around e35, depending on the quality of the ethanol. Too much octane you actually start loosing power. OX has shown you can run e30 safely on boosted applications with the stock fueling system. Anything more needs a upgraded HPFP.

what I stated is still true, there isn't an inline ethanol sensor like a GM. It's just logic in the PCM. I have no desire to ever run 87 so I didn't ask for a tune with 87 octane support. I know OZ has a single tune covering everything and e40 is about the break point. I'm not mixing fuels so whatever comes out of the ethanol pump is what I'm running, which has been perfectly fine. And I would not run the stock fuel system on a boosted 5.0 regardless of how much you "can" or whats been proven. Upgrading the fuel pump hat, lines, rails and PI side injectors is the most effective way to do it. Which is why majority of people do that and then just run e85, which IS beneficial in boosted applications.

What in the coon dawg hell are we doing? My truck knocked like a Triton under load. Now it clunks to a stop. All of a sudden I give it the throttle and it sounds like an F1 car and bangs thru the gears. Oz tune. Where are we?

Figured it out. It was the air filter.
I had a paper filter installed because when I went to get a new k&n they were out (i rinse the oil out of mine and just replace with a new filter after a few weeks). Bought a new k&n filter, did a kam reset, and the tune is dead on.

Strong, but not the same “pull” as a tuned ecoboost. Guess I need a whipple.

boost is always a good answer in my opinion.

Oz tune is great. Will definitely keep it during the winter for 93 octane.

This is not a jab to Oz. At all.

But the 5 star e85 performance tune is holy shit fast. It’s fast enough I probably need to lower the truck.

All around I am happy. Cant imagine the procharge setup if the 5 star tune is this fast. Just fyi fellas.
