Ariza 5 driving computer description, Ariza 5 driving computer upgrade.

Ariza 5 driving computer is a high-end electronic product, which uses high-end technology to read automobile data. This system will monitor whether the automobile exhaust exceeds the standard at any time from the running condition of the engine, and once it exceeds the standard, it will immediately issue a warning. When the system fails, the MIL lamp or CheckEngine warning lamp lights up, PCM stores the failure information in the memory, and the failure code can be read from PCM through a certain program. According to the prompt of fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault. The upgrade of driving computer started from abroad, and it was introduced into China as "brushing ECU, upgrading automobile computer and refitting ECU". The formal translation method is ECU calibration. Optimizing the fuel injection quantity and ignition time of the engine by rewriting the starting parameters can theoretically reduce the fuel consumption and exhaust emissions at the initial stage of adjustment, improve the performance of the engine and improve the response of the throttle valve. It can be seen from the contents of the rewriting program that in order to achieve a more reasonable air-fuel ratio, the technician will appropriately reduce the fuel injection of the engine in each speed zone.
