To see the software change log and comments go to the following forum post


Firmware is the software running inside the YourDyno box. The firmware can be upgraded automatically from within the software by the press of a button.

Firmware is automatically updated if you press the “Upgrade to latest firmware” button in Options > Firmware upgrade.

If you upgrade offline then you need to download the firmware file. Use the option “Upgrade firmware using downloaded file”. There is no harm trying the wrong file, you will just get an error message.

For new YourDyno deliveries, all is set up already from the factory, you can just press the button in the software to upgrade the system when new firmware is available.

For YourDyno hardware version 1 you need to enable this by upgrading the bootloader (only once). You can upgrade the bootloader by downloading this file and the downloader program below: YourDyno v1 Firmware bootloader

Please download firmware files below.
