You are correct. He is very aware of the need to switch to the correct map when running E85. Currently the car defaults to map 1 when starting and does need to be switched to map 2 if running E85. This is a change that has been requested from EcuTek to remember the last map run and a change I'd really like to see.
In this case, he only runs E85 on the track, and pump gas for street driving. He specifically did not want flex fuel. And I don't think he'll be lending this car out to anyone. So the chances of running on the wrong map are very slim.

This is a great point and is why flex fuel is superior to straight E85 / pump gas tunes. With a flex fuel setup there is no need to remember to switch/flash maps, fill with the right fuel, etc. Although the same situation can occur on straight pump gas if you lend you car to someone who then fills it with 87 octane gas instead of premium.
Each owner/situation is different, but most folks I've worked and talked with and are looking to run E85/pump are car enthusiasts who are well aware of the fuel they run in their car and the tune they run on. The switch from straight E85 to pump and back is like a ritual at the pump and is not for the average car owner. Again, flex fuel makes the process idiot proof.
