### Ascher Racing Artura Firmware Updater V2.1.0



This standalone firmware updater brings your Ascher Racing Artura wheel up to firmware V2.1. No additional software is required.

The updater detects the firmware version currently installed on the wheel and selects the corresponding update process:



|Current firmware|Update process|Coiled cable|Device settings|
|-|-|-|-|
|V2.0 or newer|Fully automatic, no user interaction|Not required|Retained, except button mapping|
|Below V2.0|Manual, guided by the updater|Required|Reset (one time)|



\---

#### 

#### Updating from Firmware V2.0 or Newer



Devices running firmware V2.0 or newer already have the Ascher Racing Bootloader V1.0 installed. The updater communicates with it directly and performs the entire update in software.

* No button presses and no disconnecting or reconnecting of the wheel are required
* The update runs over any working USB connection; the coiled cable is not required
* Personalized device settings are retained

One exception: firmware V2.1 replaces button mapping with the new custom modifier mode. Wheels configured with a custom button mapping return to the default layout. The new modifier mode is currently implemented in the firmware only; the corresponding configuration functionality in the Ascher Racing SimHub Plugin will follow in a later plugin release.

Close SimHub before running the updater.

#### 

#### Updating from Firmware Below V2.0



On these devices, the update also replaces the STM32 standard bootloader with the Ascher Racing Bootloader V1.0. This requires a manual procedure: the updater prompts for a button press on the wheel and for disconnecting and reconnecting the coiled cable twice.

Personalized device settings are reset as part of this upgrade. This includes Rotary Switch modes, custom clutch curves, and all other device configurations. The reset applies to this update only; subsequent updates retain the settings.

Before proceeding:

* Note down or screenshot your current device settings in the Ascher Racing SimHub Plugin
* Close SimHub before running the updater
* Connect the wheel via the supplied coiled cable; this is required for this update

After updating, reconfigure the device in the Ascher Racing SimHub Plugin before the next session.

#### 

#### Compatibility Note



The Ascher Racing Bootloader V1.0 is exclusively compatible with firmware V2.0 and above.

Firmware up- and downgrades cannot cause permanent damage to your device. That said, downgrading below V2.0 after installing the Ascher Racing Bootloader V1.0 is not a supported configuration and would require a manual recovery procedure. If you ever need to revert to the STM32 standard bootloader and firmware below V2.0 for any reason, please contact Ascher Racing support — we'll walk you through it.

#### What's New

##### 

##### Firmware V2.1



**Features**

* **Custom rotary switch modifier mode.**
Any two inputs can be freely selected as the modified pair. This mode replaces the previous button mapping; wheels configured with a custom button mapping return to the default layout.
(note: implemented in the firmware — SimHub Plugin configuration functionality still to be added)
* **Startup LED themes.**
13 color themes to choose from, displayed until SimHub takes over the lighting.
(note: implemented in the firmware — SimHub Plugin selection functionality still to be added)
* **Sleep handling for the button LEDs.**
The button LEDs switch off when the PC enters sleep mode and return on wake.
* **Button and axis initialization.**
Buttons and axes are initialized on startup and reported to the system before they are actuated for the first time.
* **Groundwork for telemetry-driven wheel settings and boost LED brightness effects.**
Prepared in the firmware; no user-facing functionality yet.



**Improvements**

* Faster boot time with immediate USB connection.
* Reduced power consumption.
* Additional stability improvements for the default lighting on system startup.

**Bug Fixes**

* Fixed incorrect button LED colors on startup under rare conditions.

##### 

##### Firmware V2.0



* **Integrated bootloader communication.**
Built-in communication with the Ascher Racing Bootloader V1.0 enables the update process to be triggered entirely in software.
(note: SimHub Plugin firmware update functionality still to be added)
* **Extended device information.**
Provides additional device information, such as the current bootloader version number.
* **Stability improvements.**
Several minor stability improvements for the default lighting on system startup.

#### System Requirements



|||
|-|-|
|Operating System|Windows 10 / 11|
