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. Here are the different firmware files:

YourDyno Standard v4: this firmware file or this firmware file
YourDyno Standard v5: this firmware file
YourDyno Ultimate: this firmware file

USB Driver:
Windows 10 installs the driver automatically. For Windows 7 and Windows 8 you need to manually install the driver.

To install the driver for Windows 7 and 8: Plug the YourDyno box into the computer, Open Device Manager, find “Ports (COM & LPT)”. You should see an entry there called USB Serial port or Cypress USBSer or similar. Right-click and choose “Update driver software”. Choose the .inf file you download here: Download driver.

For Windows 8 a special procedure needs to be followed before installing the .inf file:
– Hold the shift key while clicking on Restart
– Select Troubleshoot > Advanced Options > Startup Settings > Restart
– After Restart select option 7 (Disable driver signature enforcement)
Now you are ready to install the driver.

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. .


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.

How to know which hardware version of YourDyno you have:

  • YourDyno Version 1, Rev 1 has no marking on the electronics board
  • YourDyno Version 1, Rev 2 electronics board is marked with Rev 2. You will also see a -rev2 on the current Dyno firmware version (e.g. 1.07-rev2)
  • YourDyno Version 2 electronics board is marked with: YourDyno v2 RevAB

The first time you upgrade the firmware from within the YourDyno software, the program will ask which hardware version you have. For subsequent downloads it remembers, and you just need to press the button.
