: Navigate to the Drivers subfolder and run the DriverBound execution file to install USB compatibility for your KESS V2 hardware.
Before diving into the specifics of version 2.90, it is essential to understand what the Kess hardware does. Primarily operating via the vehicle's On-Board Diagnostics (OBD) port, Kess reads and writes the flash memory of engine and transmission ECUs. Kess 2.90
Most users recommend keeping the laptop offline while the software is running to prevent it from trying to "call home" to official servers, which can disable the tool.
: Ensures the file integrity is correct before writing to prevent the ECU from locking or "bricking". Enhanced support for modern turbocharged petrol and diesel
: Tracks vehicle voltage through the OBD connection to prevent data drops from low voltage.
This article dives deep into the capabilities, hardware specifications, software workflows, and advanced strategies for maximizing your Kess 2.90. Whether you are a professional tuner looking to upgrade or a hobbyist starting your first reading, this guide covers everything you need to know. : Tracks vehicle voltage through the OBD connection
One of the most notable advancements in version 2.90 is the expanded vehicle coverage. As automotive manufacturers implement more complex encryption and diverse communication protocols, tuning hardware must adapt. The 2.90 firmware update specifically addresses newer Bosch, Continental, and Delphi ECUs that were previously inaccessible or unstable on older versions like 2.47 or 2.80. This includes improved support for various cars, trucks, tractors, and even marine engines, ensuring that a single tool can handle a diverse fleet of vehicles.
While KESS 2.90 is for (in-car) programming, its sister tool, K-TAG , is used for "on-the-bench" programming. If an ECU cannot be read via the diagnostic port, a tuner would typically use K-TAG to connect directly to the ECU pins.
