The KESS 3 tool is the latest step in ECU tuning – it is faster and more powerful than its predecessors. The interface speed is faster than any previous Alientech program

KESS3 – new tool from Alientech ( KESSv2 & K-TAG) -all protocols in one programmer


The protocols are sold separately, so you can choose a kit to fit your needs or expand it at any time with more protocols. With KESS3, it will also be possible to upgrade from Slave to Master.

Bench and Boot protocols are for the first time available by the type of vehicle they support rather than by processor type – making it easier to compose a kit.

The new Kess3 uses the latest technology available to ensure fast reading and writing of both ECU and TCU

Alientech Suite

The Alientech Suite program that supports Kess3 is an all-in-one program. No more wandering around a complicated menu. Select the vehicle you want to read from the main screen, then simply choose the reading method “OBD” / “bench – service mode” / “Boot – direct connection to the driver PCB ”

Connection instructions 

Now clear instructions are displayed before going to the read/write screen when using Kess3. This ensures that you don’t miss important instructions and that you are up to date with the knowledge to safely read/write a driver.


Easier searching

Quick filtering to find your vehicle. No longer do you have to follow drop-down menus and waste time searching for a particular ECU. Now you can quickly jump to the protocol you need.  Filter by ECU or TCU, or fuel type – all in one place! KESS3 is the easiest and simplest to use programmer on the market.


The new Kess3 has a protective rubberized layer around the outer edge of the tool to absorb shock and impact when working in harsh conditions. In addition, it has rubber non-slip feet
