Fuel injection system controlled by vehicle location system

A fuel injection control system for controlling an amount of fuel injected through a fuel injector to be fed to an internal combustion engine mounted on a motor vehicle, comprising:

• an engine speed sensor issuing a rotation speed signal representing a rotation speed of the engine;
• an air flow meter issuing an air amount signal representing an amount of air fed to the engine;
• a basic fuel amount deriving unit that derives, in accordance with said rotation speed and air amount signals, a basic fuel amount to be injected by said fuel injector;
• a vehicle position detecting device that issues a vehicle position signal representing the position where the vehicle is positioned;
• a correction value deriving unit that derives, in accordance with said vehicle position signal, a correction value for said basic fuel amount;
• and
• a correction unit that corrects said basic fuel amount in accordance with said correction value.
