Why did you change the truck speed limit?

• 1. Improve timeliness and save costs: For goods with high timeliness requirements such as express and fresh food, increasing speed can improve transportation efficiency.
• 2. Improve road safety: Speed limits can lead to excessive speed differences between trucks and other vehicles, thus increasing the risk of accidents. Higher speeds can help avoid dangerous situations.
• 3. Comply with laws and regulations to avoid fines or other penalties for speeding: speed limits vary from state to state in the U.S. Drivers avoid penalties for speeding as much as possible by modifying truck speed limits.
• 4. Personal preference and freedom: pursuing greater freedom and flexibility, hoping to be able to independently decide on the speed of the truck.

What are the reasons for unsuccessful speed limit modification?

• ECU password restriction: If the ECU is set with password protection, you may need to release the password restriction before you can modify it.
• Engine malfunction: If there is an engine malfunction, the speed limit setting may be locked or cannot be modified. Engine faults must be resolved before modifying the speed limit.
• Truck Start Status: For safety reasons, some vehicles must be turned off or put into a specific mode before modifications can be made.
• Non-ECU Controlled Speed Limit: In some vehicles, the speed limit is not necessarily controlled by the ECU, but may be controlled by the GPS system or the instrument module. In this case, simply modifying the engine speed limit may not achieve the desired effect.
• Parameter reset requirement: It is necessary to reset the vehicle’s parameters in order to modify the speed limit settings. For example, a previously incorrect setting may need to be restored to its default state first.
• Other conditions: There may be other specific conditions, such as vehicle-specific mode limitations or hardware/software compatibility issues.

• Energy saving: By lowering the engine’s idling RPM, fuel consumption during long idling times can be reduced, thus improving fuel economy.
• Reduce emissions: By adjusting the idle speed, the engine can be made to burn fuel more efficiently and reduce emissions, which is conducive to environmental protection.
• Improve performance: Properly adjusting the idle speed can improve the responsiveness and stability of the engine, improving the overall performance and driving comfort of the truck
