The controller sends reports to the host (PS2) formed by 6 bytes:

The values for the brake notch byte are the following.

| Left rumble | Right rumble| Door lamp + Limit approach | Speed gauge | Speedometer | ATC limit |
* **Left/right rumble:** **0x00** is **Off**, **0x01** is **On**.
* **Door lamp:** **0x0?** is **Off**, **0x8?** is **On**.
* **Limit approach:** values between **0x?0** and **0x?A** representing the number of LEDs lit above the speedometer. In-game, these mark the 10 km/h right below the speed limit.
* **Door lamp:** **0x0X** is **Off**, **0x8X** is **On**.
* **Limit approach:** values between **0xX0** and **0xXA** representing the number of LEDs lit above the speedometer. In-game, these mark the 10 km/h right below the speed limit.
* **Speed gauge:** values between **0x00** and **0x16** representing the number of LEDs lit on the speed gauge. LED #23 cannot be lit. In-game, these mark 15 km/h increments in the current speed, with one lit when speed is 1-15 km/h, two when 16-30 km/h, etc.
* **Speedometer:** values between **0x0000** and **0x0999** representing the current speed. Values are encoded with **BCD 8421** (i.e. **120 km/h** should be represented as **0x0120**, NOT **0x0078**).
* **ATC limit:** values between **0x0000** and **0x0999** representing the ATC speed limit. Values are encoded with **BCD 8421** (i.e. **120 km/h** should be represented as **0x0120**, NOT **0x0078**).
