Well theres always that as well. I don’t understand why people think having an e85 map means your stuck with it? I’d think the only real hassle in running e85 and needing to switch off to a pump tune is making sure whatever fuel is left over is bled out/burned off before you got WOT happy.
I will probably run e85 only, as well when ym cars back out it wont be in summer DD status like it was the past few years, and I don’t drive far enough in it for it to be a concern.
