I think I may have misread your questions. It seems you are asking what to do if you already have the water in there, from homebrew Ethanol? Hmmmmm..... Perhaps a dual tank setup like we use for SVO in diesels. A block heater would probably help, but then you are using alot of electricity -- and is that renewably produced?

I don't think that adding water would be the right way to go. I think the problem is that ethanol has a higher vapor pressure than gasoline, and in cold weather, it is hard to get it to vaporize into a fuel-air mixture effectively. Gasoline vaporizes much easier, and gets the engine going and initiates the combustion. But water has an even higher vapor pressure than ethanol, plus it is not a fuel, so I don't think it would help. Since all of the commercially produced flex fuel vehicals that I've seen are designed to run E85, I think they just rely on the gasoline content to start in the winter. What bugs me is that I can't buy any flex fuel vehicals that are efficient -- I mean, if I want a flex fuel vehical, I have to upgrade to a full sized pickup or a V8 sedan. Where's the little 4 cylinder efficient flex fuel vehical? Guess it's not all that hard to change out carbureator jets to change the fuel air ratio yourself to allow running ethanol.
