The Norwegian government has decided to remove taxes on E85 fuel (85% ethanol, 15% regular fuel), which will reduce the fuel price by at least 50% (currently at £1/litre)!

Is it possible to remap the ECU to run safely with E85 fuel? What other modifications are necessary? I guess the environmentalists didn't think of this possiblity

 

If you've got a mappable ecu then it'll be possible to map for E85, plus it has a higher octane rating than super unleaded.
