    You can then calculate the ethanol content in the tank.

    If we had easy access to the fuel tank we could use a kit like this. Unfortunately we don't.

    This is so last decade Click here to enlarge Who is going to test the ethanol content at the pump every time? Even if you will do it, you'd need to know how much is left from the previous tank of gas to be able to calculate the new weighted ethanol content. Next you'd need to make the respective changes to the tune.

    In this decade this has been done by the flex fuel sensor and automated adjustments to the tune. Just look at Haltech, Motec, Proefi...even Hondata.

    Past E60 there are simply no more quantifiable gains on stock turbos from what we've seen so far..in fact E40-E50 is where we usually end up at

    Yes, you can fill in e85 all the time and that should be at least e70 also in winter. However, all the stations don't carry e85. So, for some of us, easier said than done.

    Yes this was done in the hopes of a simple OTS style map with E30 OTS vanos and boost settings. Something safe to start with at that level of fuel mixture.

    I end up sampling right from my tank so I know what mixture is in there. I rip the back seat out and get to the section on the passenger side of mine and pump out a cup or so.

    Maybe not any significant gains but another 5-10 and running the timing where it should be would still be worth it if people are filling up with straight E85. Just like any NA engine gain at that point as most people who like to squeeze every last HP out of their engine would still be happy with another 5 whether they can feel it or not.
