ECU flashing

Contemporary vehicle engines and controlled by electronic control unit (ECU), which determine operations of key systems: injection, ignition, idling and others [1].One of the most popular domestic ECUs is January 7.2, used in LADA automobiles and several other brands.ECU flashing enables to change stock parameters of engine operating, optimizing it for certain conditions of exploitation, enhancing dynamic, efficiency and ecology [2].During the flashing process you can adapt ECU to use alternative fuel, delete or modify work of sensor and moreover, remove manufacturer's restrictions.ECU represents a complex device that collects and contains information about engine operating algorithms.Basically, all ECUs work similarly: they receive data from sensors and control, process it according to installed program, and send signals to actuator.The program of ECU is called firmware, it can be read, installed, uninstalled or edited, affecting vehicle's behavior.Work with firmware is a primary and most important step of modern cars tuning.Here in BNTU we were working with VS 5.1, Bosch 7.9.7,January 7.2 (Fig. 1).
