Here's the blurb on E85 from the owners manual:
"The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F (-18°C). In the
range of 0°F (-18°C) to 32°F (0°C), you may experience an
increase in the time it takes for your engine to start, and
a deterioration in driveability (sags and/or hesitations)
until the engine is fully warmed up.
NOTE: Use of the engine block heater (if equipped) is
beneficial for E-85 startability when the ambient temperature
is less than 32°F (0°C)."
I'm not far from you and I have no problem with cold starts. I also have my cold start values richer than stock.
