[QUOTE="JimIII@JDM, post: 802010, member: 736"] Well Fuels like E85 require burning a much richer Air to Fuel mixture. I'm not sure what E30 would require but the E85 requires running as rich as 9:1 where traditional Non-Ethanol or E-10 Fuels are around 14.7:1 stoich. Burning that rich of a mixture requires more demand on the fueling components. This requires major tuning changes as well. Again only basing my knowledge of E-85. The Factory PCM on Flex Fuel vehicles allows the fuel mixture to adapt based on which fuel selection you put in the vehicle. But that is on stock parameters. Adding Exhaust, Cold Air intake, A Supercharger!!! is going to change the dynamics of the tuning and how much fuel is required. That's when good custom tuning makes a difference! [/QUOTE]
