The Master version of the KESS3 allows you the flexibility to read and write to the ECU without limits. The Master tool will read and save an "unlocked" file. Once the Master files have been read and saved, you can use a calibration editing software, like our ECM Titanium, to make the changes to the file. After saving the file, the modified version can be rewritten to the ECU using the Master tool; this is also known as FLASHING. During the "flashing" process, the KESS3 tool will correct the checksum so there are no conflicts with the files. This is accomplished automatically.
A solution designed for those working exclusively on automatic and robotized transmissions, with the aim of offering maximum simplicity, full coverage, and advanced features.
With a single activation, you can operate in OBD, BENCH, and BOOT modes with full access to TCUs, for reading, writing, and cloning*.
*TCU cloning: this involves transferring all the data from the internal memory of the original control unit (damaged or faulty TCU) to an identical one, either new or used. Repair professionally with reduced intervention times and maximum safety.
The new configuration allows you to work on TCUs in all communication modes supported by KESS3, without the need for additional protocol activations.
One package, one activation: ideal for workshops specialized in transmissions looking for a fast, powerful, and complete tool.

Alientech KESS3 Hardware
USB cable, needed to interface with the KESS3 instrument through the PC.
The new generation OBD cable that integrates all the communication lines used by the various car manufacturers; this cable, therefore, replaces various wirings that were used by KESSv2; more specifically, it is also able to communicate with Honda, Volvo, Lotus and Toyota.
1400SWALIM power supply, capable of providing sufficient current and voltage to communicate with the electronic control units, in a stable and safe way.
144300TALI cable, to power the instrument using a bench power supply (the power supply, on the other hand, is sold separately).
144300KBNC cable to communicate with the control units directly on the bench.
144300KTER pack which contains all the cables useful for connection in BENCH or BOOT mode. (extender).
144300T104 rainbow cable IDC 26-10 consisting of 10 wires, used to connect directly to the electronic board of the control unit.
144300T105 rainbow cable IDC 26-16 composed of 16 wires, used to connect directly to the electronic board of the control unit.
144300T106 rainbow cable IDC 26-26 consisting of 26 wires, used to connect directly to the electronic board of the control unit.

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

A simple interface to the connector and you have complete access to the data of your ECU.

This mode allows you to access all system data areas. Read, Write and Clone.

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 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 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.
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.

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.
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 our vehicle list.
