E85 question

[JungleG1337]

I saw one of the local gas station sell E85. Is this same as the mix race fuel everyone is using?

Negative this is used to mix regular gas for e30 which I heard is "magical juice" lol

1/4 e85
3/4 93 octane is what I use.

Generally I'm letting the tank get down to 10 or a little less miles and I fill up with about 4 gallons of e85 and the rest 93 octane.

The ecoboost tank size is 15.5 and their are octane calculators out on the web too.
e30 is what we typically run but only with a proper e30 tune

How's your gas mileage?

From what I've noticed....with 93 oct I averaged 23. With E30 ...21.5. Both same type of driving habits ect.

I see. Im thinking taking my car to the strip on the 23rd. Would it be better to have my tuner make my race tune to e30? or keep it at 93?

More power can be made with E30

If you have a AP3, you can have both in different slots

He has an sct x4. Can you switch maps on that platform?

As in on the fly u mean he can't just switch it on his programmer or something else? Sorry for sounding stupid but old school burn chip/flip switch guy here for different tunes.

With different seasonal blends do u change up the amount of e85 u put in? I'm from SoCal but I've "heard" out here it doesn't change much.

I don't believe so. Someone with an SCTx4 can chime in but the new tune would have to be uploaded which is a 20-30 min process. The accessport does it in 3 seconds.

He'd have to flash to stock, then flash his E30. 5-10 minutes process to do both flashes.
