KESS3 MASTER (OBD Version Car + LCV)

New at Alientech now all in one device possible

OBD, Bench and Boot programming.

Thanks to thirty years of experience and almost three years of development, KESS3 is the most advanced technical achievement ever conceived in the chip tuning industry. Alientech has made a significant breakthrough in creating something unique and exceptional that is unparalleled in the market in terms of features, comfort and versatility.

KESS3 has been designed to provide everyone from young engine enthusiasts to highly specialised mechatronics engineers with a quick and easy interface to all engine control units and automatic transmissions on the market.

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

KESS3 combines 3 read and write capabilities in a single device.  Per OBD / in Bench and Boot Mode.

OBD - With OBD mode, you can easily access all ECU data via the diagnostic socket.

BENCH - A simple interface to the connector and you have full access to your ECU data.

BOOT - This mode gives you access to all system data areas. Read, write and clone.

Master or slave? You decide!

A single flexible device that can be configured as needed, when the tool is initialised you can choose the operating mode.

MASTER - The configuration that allows you to process software calibrations in a completely autonomous way. The files read in can be interpreted by your chosen mapping software.

SLAVE: If you are not yet confident or self-sufficient in editing software calibrations, this mode allows you to work with a network of trainers who will assist you with file requests.

DEALER NETWORK: If you intend to build your own slave network of tuners, you have a reliable and easy-to-use tool at your disposal.

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

Since 1991, Alientech has been designing and developing tools for remapping ECUs. Driven by a passion for excellence, Alientech has put all its experience into this new tool.

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

A new microprocessor, latest generation I/O interfaces, new built-in sensors and powerful 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 executes your commands reliably, faster and more efficiently.


KESS3 automatically and instantly detects the correct communication line to work faster and use only one OBD cable. Ethernet, FlexRay, CAN Bus, K-Line, L-Line, J1850, J1708.

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


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

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


The renewed USB Full Speed chip allows up to a 10-fold increase in performance when importing and exporting files to and from the KESS3.

But not only that, Alientech has added a new web infrastructure to the new KESS3.

The result is an Alientech cloud with improved speed and performance.
