The Bosch Bajaj Hex File Sync is a software tool used to download and update the latest calibration files—or "hex files"—onto the Bosch ECU of Bajaj motorcycles like the Dominar 400. This process, typically performed by authorized service stations, is essential for ensuring the bike's Engine Control Module (ECM) operates with the most current software, addressing issues like software bugs, improving performance, and maintaining the vehicle's integrity. The tool is part of a two-step update process: first, the "LaunchPad" updates the diagnostic tool itself, and then "HexFileSync" downloads the specific vehicle's hex files.
