In motorsport there are many disciplines, karting is one of the variants. It is regarded as the school of great pilots. In this activity it is required to implement technological advances. The adaptation and implementation of the electronic fuel injection control system to the two-time single-cylinder internal combustion engine of 125 cubic centimeters of carburetor displacement is presented, to be used in Karting competencies, to raise its characteristic mechanical parameters such as: torque, effective power, fuel consumption optimization, by properly configuring and calibrating the programmable computerized electronic system, by adjusting the injection and ignition time. The results are validated through the development of measurement tests on the engine dynamometer, track speed (kartódrome), with mathematical analysis, which confirms the feasibility of performing mechanical-electronic truffles and adaptations and software settings that can be implemented in this type of automotive units, which mark an interesting technological novelty.
