Based on my 2 GM FFV cars you are wrong (fuelly david0031 2002 suburban) and on here 2010 Impala, yes they loose some MPG, but the suburban I had did better better on E85 than it should according to BTU's per gallon.
My stratus follows energy content & MPG almost perfectly. I don't know if there's a fuel sensor, I don't think there is and it doesn't matter, the O2 sensor does everything that needs to be done as long as they sized the fuel pump and injectors large enough to take full load with E85.
We have liquid fuels and will for a long long time.
Field corn is hardly used for people food, unless you count animals turning it into meat & tasty fat the last month of their life.
