The details
About the KESS3 Master kit — Marine & PWC OBD, Bench & Boot
A complete KESS3 for boats and jet skis, ready to use: the tool with its cables and case, the Marine & PWC OBD, bench & boot protocols activated as a master, and 12 months of Alientech’s updates and new vehicles.
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.
Will it read my vehicle?
Check Alientech’s vehicle list, or send us the vehicle or a photo of the ECU label on WhatsApp and we tell you before you buy.
