E10 New Fuel Megathread [Consolidated for all E10 discussion]

I’ve now been running E10 for the last 4-5 fill-ups (4-5 weeks) and I can honestly say the car is not that happy!
As I posted earlier, NC 3.5.
It doesn’t start that well when just off cold and doesn’t pull as well as it did and has lost 3-5 mpg.
Can a remap help? Super round here is way too expensive for my daily commute.
Rick.
