An apparatus and methods for converting fuel injected internal combustion engines normally operated with a conventional fuel such as gasoline to operate with an alternative fuel are disclosed. The methods include a synchronization method where an alternative fuel injector control signal is synchronized among two or more alternative fuel injectors throughout the engine's energy demand range; a method for transforming non-sequential conventional fuel injector control signals to individual cylinder timed alternative fuel injector control signals; a method for transforming sequential multi-port conventional fuel injector control signals to throttle body alternative fuel injector control signals; and a method which includes adjusting the timing of the start of the injection relative to the valve opening event as a function of fuel flow.
