When I contacted them earlier this year, it was still pretty new so they said they wouldn't. Just be sure to monitor your ethanol percentage carefully and stay out of high boost/WOT until you get a more refined tune but the generic ethanol tunes should be far less detonation prone than generic gas tunes. Also, change your fuel filter earlier than normal for the first 1-2 times (and/or monitor your fuel pressure carefully). This is the same route I plan to go, minus the map selector.
