ECUtec has an option to install 2 maps at once and use the cruise control to switch between them?
I think im going to put the stock rom back on the car to unmarry the oft, get an ecutek license and goto a tuner to get both a proper e85 and 91 tune at the same time. Just switch between using the cruise control map selector.

What we are trying to tell you is a Flex Fuel tune makes it so you don't have to map switch at all. It's dynamic in the sense that when the sensor sees different fuel quality it makes adjustments accordingly. Say you have a half tank of 91 in the car. You go fill up on e85. The sensor will see the ethanol content rise, and according to the tuner's programming the car will adapt to it. When the car sees the fuel quality lower back down it will pull those adjustments back out automatically.
