FWIW, just tuned a turbo Miata yesterday using the Sport ECU and flex fuel setup. Per Haltech's recommendations, we started with pump gas (E10) for the base tune. Car made 210 @ 11.5 PSI. Drained out the pump gas and dumped in 5 gallons of E85. Worked through the comp maps very easily. Ended up making 254 peak with the E85 at the same boost. Dumped the rest of the E10 we had left in with the E85. Composition sensor showed E50 and everything worked just as it was supposed to. The system worked well and was very easy to calibrate.

I guess drain all the E85 out or most of it and put gas in the tank and tune it on the dyno. After that, syphon out the gas and add as much E85 as you can and tune that on the dyno.
Sounds like quite the process that most people could not achieve.
I guess you could road tune it, starting out with E85 and later adding more gas to the mix? Might not be as accurate?

I did this car, pretty much from scratch, in about an hour and a half of total dyno time. Quicktune makes it go, well, quick.
Like any tuning, you don't need a dyno. I just prefer it and feel the results are better. You tune this on the street just like you do a regular fuel map. The process of doing the pump gas map first and then doing the E85 offsets based on that map should be followed. It can be done in the reverse order, but the numbers you need to use in the various maps become unintuitive.
