How to Remove the 90 km/h Speed Limit for Trucks?
2 Answers
The methods to remove the 90 km/h speed limit for trucks are: 1. Adjust the speed limiter screw to remove the limit; 2. For electronic speed limiters, it is necessary to go to a repair shop and ask a technician to use professional equipment to remove the limit. The reasons why a truck's air conditioning is not cooling are: 1. Accumulation of impurities in the condenser, resulting in poor heat dissipation; 2. Accumulation of dust in the air filter, leading to poor ventilation; 3. Damage to pipelines and connecting components, causing refrigerant leakage; 4. Compressor damage; 5. Expansion valve failure. Precautions for driving on highways: 1. Pay attention to traffic regulations and affix the novice driver sign; 2. Find an experienced driver to accompany you; 3. Inspect the vehicle before entering the highway; 4. Be aware of the speed limit when driving on the highway; 5. Pay attention to road signs, markings, and warning signs; 6. In case of emergency stops or accidents, ensure safety; 7. When exiting the highway, change lanes in advance.
Removing the speed limiter set at 90 km/h for trucks, I know some methods. Usually, this can be achieved through ECU tuning, which involves reprogramming the engine control unit with computer software to modify the speed limit parameters. Alternatively, you can directly replace the speed limiter hardware, such as changing the sensor or wiring harness. A friend of mine tried it but warned that it increases risks: trucks have heavy bodies, and high-speed driving can lead to poor stability, making them prone to losing control or increasing braking distance. Fuel consumption will also skyrocket, and it may cause engine overheating. The factory-designed speed limiter is for safety and fuel efficiency, complying with traffic regulations. I recommend not tampering with it unless absolutely necessary. If you must, have a professional technician handle it carefully using diagnostic tools to avoid damaging the vehicle or causing trouble. Safety first—don’t invite trouble for the sake of speed.
