How to Remove the Speed Limiter Mode in a Car?
2 Answers
In general, the speed limiter in a car cannot be removed. The threshold of the electronic speed limiter is preset during vehicle manufacturing and usually cannot be altered. The purpose of the electronic speed limiter is to prevent excessively high speeds and avoid accidents caused by speeding. The electronic speed limiter continuously monitors the vehicle's speed. When the speed reaches a certain value, it controls the fuel supply system and the engine's RPM. At this point, even if the accelerator pedal is pressed, the fuel system will not supply fuel. Most domestically produced vehicles have a top speed of around 200km/h, so they do not come equipped with an electronic speed limiter. If the vehicle's ECU is reprogrammed and some minor adjustments are made, it might be possible to remove the electronic speed limiter. However, doing so could potentially introduce hidden risks of damage to the car.
Removing the car's speed limiter might sound appealing, but I have to say it's usually not a good idea. Cars come with speed limiters from the factory to protect engine lifespan and prevent speeding accidents; removing them arbitrarily can damage components or even lead to legal issues. If you're a racing enthusiast or only use it on tracks, the legal way to remove the limiter is by modifying the ECU (Electronic Control Unit), which requires professional software like an OBD2 tool connected to the diagnostic port to adjust parameters—it's recommended to have this done at a tuning shop or authorized service center, costing anywhere from a few hundred to over a thousand yuan. I once helped a friend modify one—top speed increased, but fuel consumption spiked, and the suspension system endured more stress. Safety should always come first; when driving, ensure you select the right mode, as some cars have a sport mode that allows partial speed boosts.
