One Tool, Three Powerful Modes

KESS3 unifies three key modes into a single compact and robust device:

• OBD Mode: Communicate directly with the vehicle’s ECU through the diagnostic port for quick and convenient tuning.

• Bench Mode: Access ECU data without opening or disassembling the unit.

• Boot Mode: Full low-level access to microprocessors and memory for advanced operations such as ECU cloning and recovery.

You can configure the KESS3 based on your needs, making it suitable for users at all levels of experience.
