Ive never once seen KR on the aeroforce with E85 not even a blip. Ive been running it since Feb now its middle of July and 90 plus degrees out, and humid. Never touched the tune in this car, and I only have ONE station that has E85 in the Washington DC metro area.
If I can have such little problems, in fact zero problems relying on one station once this car gets back to ND where corn is everywhere it should be even less of and issue.
Long story short if the tune is solid you shouldn't have to constantly measure the fuel..........
