PURPOSE: A control method of an advanced injecting time by an initial duty control is provided to improve the initial timer advance property by setting an initial duty value with a certain value and controlling a timer through a PID(Proportional Integral Derivation) control. CONSTITUTION: A starting of an engine is checked. In starting the engine, a coefficient of a first proportional controller and a coefficient of a second proportional controller are set. A PID control function is calculated by using the coefficients of the first and the second proportional controllers. Without starting the engine, the coefficient of the second proportional controller and a coefficient of a second integral controller are set. The PID control function is calculated by using the coefficients of the second proportional controller and the second integral controller. Thereby, the advanced property of an initial timer is improved.
