For bikes, fuel injection has been through enough generations of refinement that throttle response has become smooth and predictable—free of the sudden cut-in of some early versions. Our fears of Federally sealed black-box operation that could never be re-tuned for a pipe or new cam were banished by digital power-to-the-people in the form of laptop-addressable racing ECUs, and on the street, devices like Dynojet’s Power Commander. For persons willing to learn the necessary skills, it is possible to adapt from available hardware electronic fuel-injection systems for virtually any engine not already so-equipped. By use of separate injectors, gasoline-burning turbo engines can be made to tolerate unusually high boost on demand by injecting alcohol. The extreme cooling effect of the evaporation of the alcohol acts like a “liquid intercooler,” pulling mixture temperature down and preventing detonation. The alcohol also has a higher octane rating than pump gasolines.
