A fuel injection control system for use with an electronic type of automatic transmission system for an internal combustion engine of a vehicle, said electronic automatic transmission system including a transmission control unit for generating a signal representative of a proper shifting of gears, said fuel injection control system comprising in combination: a plurality of injection means respectively provided at corresponding cylinders of the engine; a first sensor for sensing the opening degree of a throttle to generate a signal representative thereof; a second sensor for sensing vehicle velocity to generate a signal representative thereof, which second sensor is connected to said transmission control unit supplying the same with the signal; a control unit connected to said first and said second sensor receiving the signals therefrom for determining the number of cylinders to which fuel is injected, and controlling said plurality of injection means connected thereto; and compensating means connected to said first sensor for receiving the signal therefrom and also connected to said control unit for receiving a signal representative of the number of the cylinders to which fuel is injected, and generating a signal representative of the opening degree of the throttle under the condition that fuel is injected to all of the cylinders, regardless of the number of the cylinders to which fuel is actually injected, said compensating means connected to said transmission control unit for supplying the same with the signal therefrom, whereby said transmission control unit determines the proper shifting of gear ratios based on the signals from said compensating means and said second sensor.
