Will authorized 4S shops upgrade ECU?

Authorized 4S shops will upgrade ECU. Upgrading ECU is not a modification of the car's hardware, but rather a tuning and optimization of the car's onboard computer program using high-end equipment. Simply put, it is an upgrade for the car's computer. The purpose of upgrading ECU is to ensure that the car's fuel supply achieves full combustion while delivering optimal power output, thereby improving the car's power, torque, or reducing fuel consumption, and optimizing the car's performance. Since modern cars are designed to adapt to various weather conditions, environments, and different driver requirements, and the government strictly controls vehicle emissions and fuel consumption standards, all mass-produced cars from manufacturers use the same ECU for the same model to reduce production costs. Manufacturers cannot perform precise tuning for each individual car, hence the need for ECU upgrades to meet different requirements. Through software program upgrades and optimizations, the car can achieve its best state, mainly reflected in power and fuel consumption. After optimization, the car's power increases, fuel consumption decreases, achieving the best balance for the vehicle. During driving, it can be clearly felt that the engine's RPM increases significantly, horsepower and torque improve, and automatic transmission models experience smoother gear shifts and more seamless power transitions.
