How to Remove the Speed Limiter on Wuling China VI Vehicles?
3 Answers
Wuling China VI speed limiter can be removed at a 4S dealership. Below is an introduction to the speed limiter on Wuling China VI vehicles: 1. Vehicle Introduction: The Wuling China VI speed-limited model is the Wuling Rongguang Mini Truck, a vehicle specifically produced by Wuling for the mini-truck market. Its largest cargo compartment dimensions are 2710mm in length, 1520mm in width, and 320mm in height. As a cargo vehicle, the Wuling Rongguang Mini Truck has a maximum payload capacity of 735kg and is equipped with a 1.5L engine. 2. Reasons for Speed Limitation: The speed limiter on Wuling China VI vehicles is set by the manufacturer, primarily considering the following three aspects: first, for the safety of the driver and passengers; second, to extend the vehicle's service life; and third, to reduce environmental pollution.
I've seen many discussions among Wuling owners. The speed limit on China VI models is factory-set to comply with emission regulations, and vehicles like the Wuling Hongguang often come with electronic speed limiters. If you want to remove it, technically you can use an OBD diagnostic tool to connect to the ECU and reprogram parameters, but this involves illegal modifications that may cause the vehicle to exceed emission standards, void the warranty, or even trigger engine failures. I suggest not attempting this yourself first, as any electrical issues could cause trouble. It's best to drive to an authorized 4S shop or professional repair center and let technicians use proper equipment for inspection—they know how to safely optimize without violating regulations. Maintaining reasonable speeds during daily driving is beneficial for both the vehicle and the environment.
Having driven domestic cars for over a decade, I must say the speed limit on Wuling's China VI models is indeed bothersome, but it's a regulatory requirement aimed at reducing emissions and protecting the engine. The most direct way to remove the speed limiter is to reprogram the ECU with tuning software, but this isn't something you can achieve by simply buying an OBD plug—inexperienced attempts might damage components. Personally, I think the risks are too high, and getting fined by traffic police for modifications would be even more troublesome. It's better to ask a mechanic during regular maintenance checks; they can inspect from the control system's source. By the way, tire pressure and fluid conditions might also affect speed performance, so comprehensive maintenance is key to safety.
