Several injection and ignition systems have been developed and tested since the invention of the internal combustion engine. As environmental regulations have become more stringent over the years, an electronic injection and ignition systems of the mixture air/fuel was implemented in the vehicles. Since then these systems have constantly been improved with the inclusion of devices, sensors and actuators that help them work more efficiently, both to gain power and for the enforcement of environmental laws in force in each country. For the correct operation of the engine electronic management it is extremely important to develop a software that can perfectly control the inputs (sensors) and outputs (actuators) information. The task of adjustment and calibration of the software requires a programmable module, which is connected to the vehicle and tested with various settings until an ideal fit between performance and emissions can be reached.
