Alientech KESS3 | Master Version | ECU tuning tool

Renewed architecture

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 HEART OF KESS3: THE CPU
The most powerful microprocessor on the market. 7 times more powerful than previous generations. Pure power that can execute commands more reliably, faster, and more efficiently.

FAST LOGIN 

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.

THE 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 being, an Alientech cloud with improved speed and performance.

1. How can I interface and program the control units?

With KESS3 you can program the engine control units (ECU) or transmission control unit (TCU) in three different ways:
OBD - With the OBD mode, you can easily access all the ECU data through the diagnostic socket.
BENCH - With the Bench mode you can access the ECU data directly from the connector
BOOT - With Boot mode, with the engine control unit opened, you could connect directly to all the memories of ECU/TCU.

2. What is the difference between Master and Slave?

As a Master user, you can read the files in clear. This allows you to operate independently in order to remap and reprogram the ECU with modified files. As a slave user, only your master will be able to decrypt your files. (Recommended choice for taking the first steps in chiptuning, supported by your Master)

3. What types of vehicles are supported?

Alientech supports hundreds of thousands of vehicles. Not only engine control units, but also transmission control units equipped on cars, motorcycles, tractors, trucks and boats. To know all the vehicles that Alientech supports, you can easily consult vehicle list.
