This work describes a project of an opened Engine Control Unit (ECU) that is formed by micro-processed electronic system capable of managing electrical signals that come from sensors installed in the engine an that from those in-formation, is able to control an engine of internal combustion. In order to use this ECU a digital signal process(DSP) was chosen from Texas Instruments Inc. Model TMS320F2407A. The parameters of this system configuration, aswell as the strategy used to control the engine are available to the operator by an Human-Machine Interface (HMI). There was a concern of doing a friendly interface. There have been some previous tests at a engine test bed with the objective of testing the ECU projected. As a result, this ECU achieved a satisfactory torque and power development, surpassing in some moments the traditional one. Concluding, it's important to mention that this work is very signi¯cant for those who want to develop some kind of study in the internal combustion engines area, because of the °exibility of the projected system.
