Alientech – KESS3MA011 – KESS3 Master – Bike – ATV & UTV OBD-Bench-Boot Protocols activation “Bundle”

Alientech’s KESS3 is a professional ECU programming/tuning interface that allows you to read from and write to an engine control unit (ECU) using different methods:

• OBD Mode – via the vehicle’s diagnostic port

• Bench Mode – directly on ECU pins with the ECU removed

• Boot Mode – direct microcontroller board connection for deeper access

The “Master” version of the software gives full read/write control across both OBD and Bench/Boot methods and lets you create custom tuning files or work with multiple file providers, as opposed to the more limited “Slave” version which is often tied to a single provider.
