I will be installing an ethanol % sensor similar to yours very soon...I want to have the flexibility of switching tunes based on ethanol % read out...
Mixing percentages has been pretty straight forward...So far e20 tune is producing great results...on to e40 tuning very soon and then i'll extrapolate between the 2 tunes for e30...

The mixing is easy
... I'm talking about accidentally selecting the wrong slot on the accessport. That would be way too easy and could be catastrophic.

I use one of the gauges slots on my access port to show which map slot I am running at any given time...easy to keep track this way

Good idea
Also I monitor timing corr. cyl #1 and knock cyl #1 along with the map slot selected just to play it safe....
Hoping Cobb will provide us with auto map selection based on ethanol percentage in the future similar to what they do with the Subie's and GTR's...
When I'm logging, I usually log all 4 cylinders for ign correction because while tuning there can be a difference between them. Once the tune is complete, I usually monitor ign corr in cyl 1, air/fuel, boost, oil temp, charge temp. Sometimes I'll watch knock, but it usually correlates with the ign correction.

yes....when logging I also do the same...So far I'm pleased with what e20 has yielded and pretty much have completed most of the e20 tuning ....As I mentioned earlier I'm on to e40 next which is high as I'm going to take ethanol %...I'll develop the e30 tune by extrapolating results between e20 and e40 tunes....As this is primarily a daily driver for me I'll probably be staying between e20and e30...actually e20 feels amazing as is...

As a few folks who have already tuned their FiSTs with ethanol in the past have said...Ethanol is truly amazing and quite forgiving...I've never seen my boost profiles and timing advances along with positive ignition timing corrections as consistent and well behaved as this (shown below) on good ol' CA 91 knocktane...
e20 / 4th gear / WOT / 2000~6000rpm
Ignition timing (e20): +16 deg @ ~6000rpm
Boost: +24psi @ ~2500rpm to ~3700rpm / +20psi from ~2350rpm to ~5000rpm / +15.5psi @ ~6000rpm
Ignition corrections (cyl's 1-4): +5's @ ~6000rpm...
I think what I have so far is fairly conservative...Although looking at all the data I've logged to date it does appear as if I'm getting fairly close to point of diminishing returns (at least for e20) using MBT as a tuning strategy...As I recall Razor saying he found using e40 was pretty much at the upper limits with e45 not really yielding much more...I'll probably want to keep somewhere between an e20~e30 mix myself...

I have a 5 gal container I fill up and store...Currently the nearest ethanol station for me is ~22 miles away...but within the next few months we have another one opening up ~5 miles away...
I've gotten used to carrying a smaller 2 gal container of ethanol to the regular pump gas station which I have it marked at 1 gallon ...When I fill up I usually add either a 1 to 6 mix or 2 to 10 mix which lands me around ~+20%...I'm really looking forward to getting the ethanol percent kit install soon...
