A system for controlling fuel injection has an engine speed sensor, a throttle position sensor and an atmospheric pressure sensor. A first basic injection pulse width is calculated based on detected engine speed, throttle position, and atmospheric pressure. A memory storing correcting coefficients dependent on engine speed is provided, and a correcting coefficient is derived from the memory in accordance with the engine speed. The first basic injection pulse width is corrected with the derived correcting coefficient to provide a fuel injection pulse width signal for operating a fuel injector.
