How to Remove the 110 km/h Speed Limit on Wuling Rongguang China VI?
2 Answers
Electronic speed limit is designed to prevent accidents caused by excessive speed. If you insist on removing it, you need to reprogram the vehicle's ECU and make some minor adjustments, but this may potentially damage the car.
I've been driving the Wuling Rongguang for two years, and the speed limit of 110 km/h indeed affects highway efficiency. Previously, I used an OBDII diagnostic tool connected to a mobile app to adjust ECU parameters, which removed the speed limiter, allowing the car to exceed 120 km/h. The process was simple but time-consuming: first, purchase an inexpensive device like the Launch X431, connect it to the vehicle's port, and modify the software limits. However, after the modification, fuel consumption increased slightly, and the malfunction indicator light occasionally illuminated during cold starts. The speed limit is set to protect the engine under China's National VI emission standards, and removing it may accelerate component wear or be illegal. It's advisable not to tamper with it yourself; instead, seek a professional auto repair shop for a safer approach. Check the vehicle manual first to confirm feasibility, and never overlook safe driving. Even with increased speed on the highway, pay extra attention to the stability of the braking system.
