E85 on an Elise?

1. What are the Pros and Cons to setup E85 for an Elise?
Lotus did it on an Exige.

A. EFI vs. Charle X ECU programming?

B. What does it take to be able to to run E85 with a switch back to 91?
Which Injectors?
Whole fuel system?
If so what do you buy?

This Station is close to me
Pearson Fuels

The E85 Lotus video said all that happened was upgraded fuel delivery and tune, so I think the parts can last, as long as you give it a cleaning and new fuel filter.

If you got a supercharged Lotus, I'd get the 255 lph walboro fuel pump, fuel return system, 630 cc injectors, and either the AEM FIC or EFI and have maps between 91 and E85.

If you got a NA lotus, EFI all the way, and smaller injectors for your NA needs.

Remember, E85 will run more fuel per combustion stroke than pump gas, so your fueling requirements per stroke go up than what you need for gas.

Running E85 is just like running 110 leaded gas with water injection...
