I know that for a given quantity premium unleaded 95 ron CF triple=20 distilled ethanol, Ethanol has a lower calorific value but a higher=20 octane. Which means the MPG wouldn't be as good, but the engine can run=20 a higher compression ratio to get maximum performance from the=20 available fuel. Larger injectors and a remap or custom ECU (about =A3200+= =20 the dyno time to map for the higher fuel needs) would sort that. If you=20 need to compromise, the same larger injectors could be duel in a=20 dual/flex setup. If you used a low compression head and an ecu=20 controlled low pressure turbo with knock sensing, you could still run=20 the high ignition advance even using a distibutor, without risk to the=20 engine. High proof ethanol does little damage if not excessively=20 contaminated, and we don't have continuos temps low enough in winter to=20 worry about the need to "blend" like Scandinavia and parts of the US.=20
So, what do you know about running engines on high ethanol fuels? being=20 that you are a welder, that would be something you dealt with everyday.
No, I would spend about =A3200 GBP on an ECU and map that. I would leave=20 the original factory one alone. I can't believe you are too stupid to=20 have read that.
