regular swapping from E85 to pump
any issues with continually swapping fuels?
just get your twin maps setup and hold off the boost while the fuel changes over?
how do you manage mixing pump with e85 just run down on each as much as poss before filling up ?

When going from E85 to gas...
I run it until the low-fuel light comes on plus 10miles, fill up with 91 and lower the boost. I would not do any tuning on the first tank.

I run it until the low-fuel light comes on plus 10 miles, fill up with E85 and leave the boost turned down for the first tank. Once again, I would not do any tuning on the first tank.
Going from E85 to gas is easy, as there are gas stations everywhere. The most challenging part for me is going from gas to E85, as there is only one E85 station in my general area - about 5-6 miles away. Trying to get there right when the fuel is almost empty is sometimes vexing.

I'd say having E85 only 5 miles away makes u luckier than most people

Not to jack the thread, but with duel map switching, does the boost controller have to be ecu controlled? Is there a way around map switching with a MBC? I guess you'll have to adjust where your boost was at for pump and e85 using your boost gauge with a MBC.

Two full turns will switch you between 28 psi and 22 psi, for example.

This is good info guys. I just picked up a car with an E85 tune and a 91 tune with the switch box. I plan to use E85 all the time in town but I intend to drive long distances where E85 will be hard to come by. I have a manule boost controller as well. Should a Wide band be used as well. I plan to get one any way.

Maybe a stupid question.
On My old Turbo TA I was able to pump out the 91 in the tank thru a shrader valve on the fuel rail and out a tube in to a gas can. I did this by jumping the fuel pump and running it till the tank was almost empty.
Is there a way to drain the tank like this on an Evo 9?

The Evo scan method is prefered I assume? Or is the drain portion on the take easy to get to. I just hate the thought of having to run out of gas to be able to swtich fuels. Also if I decide to take a quick road trip I don't want to be screwed or forced to drive around till empty before leaving....
Thanks guys...

You don't have to drive around til empty. E85 fluctuates from E70 to E85 throughouot the year anyway. So, if you're in a situation where you have a 1/4 tank or something like that, you'll be fine filling up with the other fuel.
Obviously, if you can, run it down as much as possible, but you will be fine and your fuel trims will take care of any close loop fueling. Just be careful with open loop/WOT AFRs until you run through the tank and fill up again.
