Measuring method for feedback provision during development of fuel map in hexadecimal format for high-speed racing engines

Abstract Electronic systems of control units for powerful engines are distinguished by a structure of control algorithms and determined modification software. A modification of these systems is performed by means of data field editing in order to reach the maximum output parameters. Active algorithms of control units have got a notable complicity and a mutual interrelation. The control software operates with numerical combinations in hexadecimal format. There were suggested types of fuel maps and they were tested using measuring at powerful engine in four sequences. During all running measurements there were monitored simultaneously operational parameters by means of a data link. Results of measuring at the complex station of cylinder dynamometer confirm a relevant contribution in the area of an engine power output characteristic by means of a developed hexadecimal matrix. The characteristic of torque behaviour illustrates a fluent increase of torque values in a wide speed range.
