The KESS3 is the latest ECU tuning tool from Alientech that replaces both the KESSv2 and K-TAG. KESS3 gives you more control than its predecessors, KESSv2 and K-TAG, and can be upgraded without the need to spend money on new hardware. This new tool allows users to remap in a faster, easier way than ever before, with the ability to use both OBD or Bench Tuning methods from the same device. You no longer need separate tools for OBD and Bench Tuning. With the new KESS3, this is now a combined feature.

100% Original Alientech KESS V3 KESS3 ECU and TCU Programming via OBD Boot and Bench

A single flexible device that can be configured as required, when the tool is initialized, you can choose the mode of operation.

MASTER - The configuration that allows you to edit software calibrations in a completely autonomous way. The read files can be interpreted by your choice of remapping software.

SLAVE - If you are not confident yet or sufficiently autonomous in editing software calibrations, thanks to this mode you can work with a network of trainers who will support you file requirements.

If you intend to create your own slave network of tuners, you will have a reliable and easy to use tool.

A new electronic architecture. 30 years of experience and passion take shape.

Since 1991 Alientech has been designing and developing tools for ECU remapping. Driven by the passion for excellence, Alientech has incorporated all their design experience in this new tool.

Every aspect of KESS3 is carefully designed to achieve performance, operational flexibility, and ease of use. Its renewed architecture exploits the full potential of each component.

New microprocessor, latest generation I/O interfaces, new built-in sensors and high-performance EEPROM and FLASH memories are the main features of KESS3.

The most powerful microprocessor on the market. 7 times more powerful than the previous generation. Pure power that can execute your commands reliably, faster and more efficiently.

KESS3 automatically and instantly recognizes the right communication line, to work faster, using only an OBD cable. Ethernet, FlexRay, CAN Bus, K-Line, L-line, J1850, J1708.

All the essential lines to start any operation inside the vehicle in total safety.

GPS, Accelerometer, Bluetooth, and Wi-Fi. All embedded in one platform.

The combination of these features and the constant technological developments that distinguish us will allow us to develop many new functions in the future.
