* Powertrain Control Module (PCM): This is the "brain" of the car's engine and transmission. The PCM receives input from various sensors (speed sensor, throttle position sensor, etc.) and uses programmed parameters to limit the engine's output at high speeds. This is the primary location of the speed limiting logic; modifying it requires specialized tools and knowledge (and is generally not recommended).
* Transmission Control Module (TCM) (if applicable): In some vehicles, the TCM may also contribute to speed limiting by controlling shifts.
* Speed Sensor: This sensor tells the PCM how fast the vehicle is going. A faulty speed sensor can affect the functionality of the speed limiter, but it's not the limiter itself.
In short: You can't physically locate a "limiter" to remove or disable. Any attempt to bypass or increase the top speed involves altering the PCM's programming which requires specialized tools and expertise. This is extremely complex, can void your warranty (if applicable), and might lead to unsafe driving conditions.
