Can Qoros 5 refresh the car system?

Qoros 5 is okay. But it needs to be done by professionals. This kind of flashing operation has a professional term in the automotive industry, flashing the ECU. Flashing a car's ECU actually means flashing codes and programs with stronger execution capabilities into the ECU inside the car, which is also a modification of the code. Only in this way can we reduce execution errors and prevent the car's engine from being unable to obtain correct instructions due to code errors, thereby failing to reflect the car's stronger performance.
