An engine of a race car is exposed to permanent modifications. As a consequence of realised modifications, the engine’s parameters are still changing. A correct control of the supply of such an engine needs many corrections of the single parameters and sometimes also of the algorithms that are used. In this document, we have presented the structure and the functioning of the programmable controller for combustion engines with spark ignition, designed for a company executing the tuning of sports cars. In the first part, the method of connection of the computer with the target system has been presented. The second part has been dedicated to the working algorithm of the controller and the structures of data. The summary presents the possible directions of further development of this project.
