Wife's is too new to play games with yet...early reports say the engine is stout enough to handle double the stock hp.
How did the Audi run on almost E30 compared to petrol? Snoopin' 'round I speculated somewhere betwixt E20-30 would be the sweet spot.
At the same time I'm looking for folks w/turbo 4s that boosted the turbo a bit & ran ethanol mix.
Thanks for the info.
It ran just fine...couldn't tell a difference one way or the other over running straight premium. Fuel mileage did take a slight hit, but I was after a reduction in price to fill the tank. Instead of using premium, I would do roughly 70% regular pump gas and roughly 30% E85. That usually got me right around E30 final mix with an octane rating just over 91.
How many miles on the clock running 30% ethanol? Did you change heat range on plugs?
I figure I need a stoichiometric air fuel ratio of around 13.7 whilst on an even keel, but the electronics are still on petrol time. The somewhat saving grace of the turbo is always rich setting from the factory.
