Marine & PWC protocols — OBD, Bench & Boot (master)

Adds the Marine & PWC OBD, bench & boot protocols to a KESS3 you already own, as a master. Alientech activates them on your tool’s serial number: no second tool, nothing to send back.

What it tunes

Engine ECUs in outboard and inboard marine engines and personal watercraft (jet skis).

How it connects

Every way in: by OBD through the diagnostic socket without taking the ECU out, and on the bench or in boot mode with the ECU out of the vehicle, for ECUs that cannot be read by OBD and for full backups.

Your own files

As a master, KESS3 opens and saves every file it reads and you write the maps yourself, in ECM Titanium or the tuning software you already use. A master can also run slave tools of its own.

Before you order

Send us your KESS3 serial number with the order, so the protocols go on the right tool. Not sure what your tool already has? Send us a screenshot of it in the Alientech software.
