There is less energy in ethanol then there is in reg-unleaded gas. So to have your engine working properly your fuel injectors need to spray more fuel to compensate. A flex fuel vehicle has a sensor in the fuel to detect how much ethanol is present and it will remap the fuel curves to compensate.
I would imagine that the adapter kits are something similar, but maybe more primitive like just re-mapping the fuel curves. So it will work better on e-85 but will be running rich on reg gas. Or maybe there is a switch so you can choose one or the other depending on what you just filled up with and it will optimize it for e-85 or reg gas.
Although there is less energy in ethanol the hp potential is much higher then unleaded gas. 100% ethanol is 116 octane and e-85 is 106 octane. Running 12:1 compression ratio on e-85 would not only make more power but you would actually gain some fuel economy.
