E85 Blenders please chime in.

[Colorado-SHOBro]

I've tested every possible blend, including straight E85...

FoMo. . . Are you pretty settled in on E45 tune in your sig being the happy place for the blends you've tested? At a certain level did you reach a point of diminishing returns on increasing the Ethanol content? Just curious for some feedback since your the pioneer of the E blend testing with Brad.

Love E45...easy to mix and now we have full pressure on the rail...Brad is a tuning wizard!

I think the point of diminishing returns is about E65 but don't get me wrong, E45 has plenty of effective octane.

nice. what sort of mpg you seeing w/ the E45?
i just stepped from E20 to E30 and the FRP didn't drop any measurable amount so i'm curious how much E the car would handle( i also have the wastegate mod which helps). IIRC 13+ cars can maintain a little more rail pressure than my 11 tho

Pretty good for E30

How much e-blend to use in the car safely ? Can I go 50-50 ?? I have now e-30 :-)

Not unless you're willing to change when and how much power enrichment is applied.

On the way to my destination I only got about 20.5mpg, but my avg speed was closer to 75-80 still using cruise control. Which I thought was a drastic change for 10-15 mph

Ya, fell off a cliff there.  Wonder why.

With my old MKS as well as my new Conti, I have found that speed makes a huge difference.  Driven in the 60 MPH range, my MKS would get close to 30 MPG but at 75-80 it would be closer to 24-25. 

Regarding E85, my wife's naturally aspirated Taurus is a flex fuel vehicle but E85 drops the mileage pretty dramatically - at least 4 MPG.  On the flip side, I have been running one of Brad's E-tunes in my Continental and using approximately an E40 blend and my fuel mileage is just as good or better as when I run E10.  Apparently, the advanced timing is making up for typical characteristics of poorer mileage with Ethanol.

Only to save a few cents on fuel, you understand.  Only an unruly hooligan would have an E40 tune in their Continental for performance gains.

Lol,  I thought it was just me...

If I had a beefy pump like Bruce's conti I would upblend to E65 and turn off enrichment completely.

Let's get real, I'm gonna do it anyway.

For science.

Lol.
