That being said, not sure if the flex sensor adjusts fueling depening on alcohol content, but it should auto adjust the agressiveness on the fly.
They have 4 separate flashes and the one I got is specifically for 50/50 E85 and NO flex fuel sensor.

What they should do is ship the DME back with instructions on how to set your maps to work correctly with the new flash.
