The latest Alientech tool that combines three operating modes: OBD, Bench and Boot mode.

Thanks to thirty years of experience and nearly three years of development, KESS3 is the most advanced engineering achievement ever conceived in the chip tuning industry. Alientech has made a significant breakthrough to create something unique and extraordinary, which has no equal in the market, in terms of functions, convenience, and versatility.

KESS3 has been developed to provide everyone, from the young engine enthusiast to the most specialized mechatronic technicians with a quick and simple interface to any engine control unit and automatic gearbox on the market.

Sensational performance, high operational flexibility and ease of use allow you to interface with engines and gearbox control units with a single tool.

  • OBD — access to the ECUs through the vehicle's diagnostic socket
  • BENCH — an interface to access the data of the ECU in bench mode
  • BOOT — access to all system data areas: Read, Write and Clone

Universal Master & Slave Tool

The mode of the tools is configured at initialization.

  • MASTER — this configuration allows you to work in a completely autonomous way: the read files can be edited by your choice of remapping software (sold separately).
  • SLAVE — connect your tool to a third-party specialist that will provide you with the tuned files.
  • DEALER NETWORK — for those who want to create their own network of tuners.

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 all 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.


The renewed USB Full speed chip allows an up to x10 increase in performance of importing and exporting files to and from the tool.

Alientech has also added a new web infrastructure to the new KESS3. The result being, the Alientech cloud with improved speed and performance.
