Alientech – KESS3MA013 – KESS3 Master – Marine & PWC OBD-Bench-Boot Protocols activation “Bundle”

Master Tool Only: This activation applies to the Master version of the KESS3 tool, which means the user can create and edit tuning files and isn’t limited to a single file provider (unlike “Slave” tools).

OBD Access: Allows you to read from and write to supported ECUs via the standard OBD diagnostic port when the marine unit is in its installed state.

Bench & Boot Access: Adds the ability to access the ECU directly when it has been removed from the vehicle (bench) or put into a special boot mode for low‑level access, giving more options for reading/writing and recovery.
