What are the drawbacks of Che Yi Sheng's hidden feature flashing?

[StRonan]

The drawbacks of Che Yi Sheng's hidden feature flashing include affecting the vehicle's warranty, potential refusal of warranty service by 4S shops, incorrect car data parameters, increased fuel consumption, engine shaking, and other abnormal symptoms. No warranty service: If the car has had its hidden features flashed (specifically the ECU), even during the warranty period, it may not be eligible for warranty service at 4S shops. Reduced engine lifespan: If the ECU is flashed to enhance power, it will not only increase fuel consumption but also reduce the engine's lifespan and accelerate the aging of other vehicle components. Principle of flashing hidden features: Modifying the ECU involves altering the factory-set program to change the engine's operation. The so-called "ECU program" is essentially a set of algorithms stored in memory. It processes signals converted by the controller from input devices, generates corresponding command signals, and transmits them through output devices. Therefore, modifying ECU parameters is essentially altering these algorithms.
