E85 Question

What percentages of ethanol is it safe to run on a pump gas tune and vice versa?
Lets say you got your car tuned at 70% ethanol, would it be safe to run 50%? Can the ecu compensate? And let say I had 2 gallons of Ethanol left and need to fill up with pump gas and was left at, lets say 20-25% ethanol, would I be able to run a pump gas tune?
I don't like the idea of having to sit and completely run out the tank. Too stressful.
Thanks

To clarify for those that may be looking for this information in laaymans: Blueflex has an app that you can download and sync via bluetooth to the unit for ethanol content readout where as drivenfab as Bryan has stated, uses innovate which is a gauge. You must mount this gauge and provide power to it in order to get an ethanol readout so it can send the appropriate signals to the ECU.
