The elecronic control unit works exactly same way with the original electronic control units of the cars when running on gas. The electronic control unit (ECU) checks signals coming from gasoline injectors, the pressure and the heat of the reducer and also the pressure of suction manifold to calculate the optimum gas needed for each cylinder. Our ECUs which have an import software are two types (version 1 and version 2) which are suitable for 4,6 and 8 cylinder cars. It provides a perfect tunning option for turbo and full group cars. They are metal cased and in black color. These softwares which provide highly sensitive calibration opportunity are resistant to mobile phone signals and high temperature.
