Modification of these systems is performed using a data field editing in order to reach the maximal output parameters. The active algorithms of the control units gained a remarkable participation and mutual relation. The control software is operating with the numerical combinations, which are described in a hexadecimal format. There were suggested various types of the fuel maps and they were tested by means of measurement realised during four sequences of a powerful engine. At the same time there were also monitored, during all the operational measurements, the working parameters using a data link connection. The results obtained from measurement that were performed at the complex dynamometric station confirm a relevant contribution in the area of the engine power output characteristics utilizing the developed hexadecimal matrix. A typical characteristic of the engine torque demonstrates a continuous increase of the torque values within a wide range of the engine speed.
