Method for controlling the fuel supply in a cylinder of a four-stroke internal combustion engine with controlled ignition; the control method comprises the steps of: determining, prior to the exhaust phase, a first forecast (PPR-1) of the suction pressure during the suction phase; determining, prior to the exhaust phase, an initial programming of injection of fuel as a function of the desired air/fuel ratio λDES and the first forecast (PPR-1) of the suction pressure during the suction phase; determining at the end of the exhaust phase, a second forecast (PPR-2) of the suction pressure during the suction phase; and determining, at the end of the exhaust phase, a final programming of the fuel injection as a function of the desired air/fuel ratio λDES, of the second forecast (PPR-2) of the suction pressure during the suction phase and of the initial programming of the fuel injection.
