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.

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 and write.
CLONING - A process wherein the engine unit is replaced in the car with no need for further coding.

Every aspect of the KESS3 tuning tool is 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 high-performance EEPROM and FLASH memories are the main features of KESS3 tuning tool.

The KESS3 uses 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 efficient.

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.
