Fuel Types, running 'nols in a Zed

Living in the land of sugar beets, there is plenty of material around for brewing alcohol and as its not for drinking, the ethanol (and other alcohols which brew) is fairly easy and safe to do - just don't smoke.

my question is, running this in a zed. I know about various seals dissolving etc but could a conversion be made to the engine and obviously timings to cater for higher alcohol, either mixed in the fuel or directly injected. I understand that LPG can run, albeit with the issue of the engine leaning out much early but can be overcome with custom ecu's and dynamic mappings.

I also am aware, that the fire service does not carry equipment for high temperature fires and why you aren't allowed to run aviation fuel on public roads etc - so maybe why a mixture rather than a tank for direct injection might be the way forward.

I'm all for trying to reduce my fuel bills, ok so a dynamic ECU would take years to offset from fuel costs but thats another story and will come out of the 'capital' budget rather than 'operational' budgets :D It needs to be dynamic, as some days it may or may not have alcohol in the fuel. I also note, that polish vodka (you know the stuff, sold in plastic bottles...) sometimes sells very very cheaply at the supermarket.

You can brew 2500L of diesel each year before road tax, so I guess the same must be similar for petrol based.
