KESS3 Master: OBD, Bench, and Boot Programming.

Thanks to thirty years of experience and nearly three years of development, KESS3 is the most advanced engineering achievement ever conceived in the Chiptuning 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.

KESS3 combines 3 operating modes in one tool. OBD, Bench, and Boot mode.

OBD – With the OBD mode, you can easily access all the ECU data through the diagnostic socket.
BENCH – A simple interface to the connector and you have complete access to the data of your ECU.
BOOT – This mode allows you to access all system data areas. Read, Write, and Clone.

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 a passion for excellence, Alientech has incorporated all its design experience into 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 CPU
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.

LINES OF COMMUNICATION
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.

PROJECTED TOWARDS THE FUTURE.
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.

PERFORMANCE
The renewed USB Full speed chip allows an up to 10x increase in the performance of importing and exporting files to and from the KESS3.
But not only that, Alientech added a new web infrastructure to the new KESS3.
The result is an Alientech cloud with improved speed and performance.

Resilience and Durability for your workshop.
The KESS3 case design is completely new. Alientech has provided added value by researching and incorporating the best usable materials. Designed to offer you versatile and rugged mobility, thanks to the durability of the materials. KESS3 is built around a fiberglass shell which gives it lightness and flexibility. An ergonomic shell is resistant to shocks and vibrations.
An exceptionally strong tool that can be taken anywhere.
