Firmware Upgrade (Race Vest)

This guide covers updating and configuring the Tech‑Air Race Vest on Windows PCs. It walks you through driver installation, software download, and firmware flashing so you can get the most out of your vest. If you have any questions or need assistance, please email us at [email protected].

What You’ll Need

  • Windows PC or laptop (XP, 7, 8, 10, or 11)
    • Must be signed in to an administrator‑level account (i.e., you can install software without IT intervention).
  • Micro‑USB to USB‑A cable capable of data transfer
  • Tech‑Air Race Vest
  • Approximately 30–45 minutes

1. Install the Vest Driver

  1. Plug the vest into your PC without powering it on.
  2. Windows will automatically detect the device and install the necessary driver in the background.
  • Tip: If you see an error like “FTD2xx.dll not found,” try a different cable—some cables only provide power and won’t carry data. 

2. Download Required Software & Firmware

  1. Tech‑Air Connect Software [link]
  • See our dedicated article for download instructions.
  • Firmware Files (choose one):
    • Race Firmware (4.09R) — for track use [link]
    • Street Firmware (4.09S) — for road use [link]
  • Note where these files save (usually your Downloads folder).
  • Why download from here?
    We maintain the latest versions and archive older releases. This prevents confusion caused by installing outdated firmware from third‑party portals.
