Generally manifold pressure, rpm and in some cases injector duty cycle. Depends on the system. However, the basic systems simply use an on/off control. There is nothing progressive about them. Reach a certain boost level or manifold pressure and they turn on, drop below and they turn off. We're talking very small quantities, a fine mist.
There are two problems with ethanol. The first is simply availabilty. Outside the midwest, availability of E85 let alone straight ethanol is very limited. The second is the corrosive properties. While the newer injectors we install are good, the rest of the fuel system was never designed for it. Even today, new cars designated for E85 use have specialized fuel system components. I suppose it could however be done. E85 alone is 105 octane.
