How to flash the car's ECU?

[LeAddyson]

To flash the car's ECU, the method is: use a read/write tool to reload the modified data into the system. The ECU refers to the vehicle's onboard computer, whose components include a microprocessor, memory, input/output interfaces, analog-to-digital converters, as well as shaping and driving circuits. The function of the ECU is: based on the programs and data stored in its memory, it performs calculations, processes, and judgments on the information input from the air flow meter and various sensors, then outputs commands to provide the fuel injector with a pulse signal of a certain width to control the fuel injection volume. The ECU has self-diagnosis and protection functions. When a system fault occurs, it can automatically record the fault code in RAM and take protective measures to read a substitute program from the aforementioned inherent programs to maintain engine operation.
