1: Understanding OBD2 Speed Limiters

1.1: What is an OBD2 Speed Limiter?

An OBD2 speed limiter is an electronic device that connects to a vehicle’s On-Board Diagnostics II (OBD2) port to control its maximum speed. According to a study by the National Highway Traffic Safety Administration (NHTSA), speed limiters can significantly reduce the risk of high-speed accidents. These devices are programmed to prevent the vehicle from exceeding a set speed, enhancing safety and reducing fuel consumption, as detailed by the EPA.

1.2: How Does an OBD2 Speed Limiter Work?

OBD2 speed limiters function by intercepting and modifying the signals sent to the engine control unit (ECU). Once the vehicle reaches the pre-set speed limit, the device restricts further acceleration by limiting fuel supply or adjusting the throttle. This process ensures the vehicle cannot exceed the designated speed, improving overall safety and efficiency, explains Bosch in their automotive technology overview.

1.3: What are the Benefits of Using an OBD2 Speed Limiter?

Using an OBD2 speed limiter offers several benefits. A report by the Insurance Institute for Highway Safety (IIHS) indicates that speed limiters can:
