Alientech Kess V2 Slave


To create KESSv2, Alientech’s team of designers and engineers developed a new tool that interacts with its software in a very simple and functional way: it recognises the firmware protections of the ECU, evaluates engine and battery conditions and, in case of a malfunction of your PC, completes the writing as if nothing happened.

The first time you use KESSv2 you realise just how easy and quick it is to get updates, download operating manuals, start reading an ECU, manage files, and write the right file at the right moment. You never have to worry about the Checksum or how to make a connection. KESS Suite, the software supplied with the OBD Programmer, helps you choose the car, the bike, the truck, the tractor, or the ECU you want to tune.

Cars, Bikes, Trucks, Marine and Tractors

We know that the tuning world is not only narrowed to cars or bikes, any engine can be improved. For this reason, we have introduced new communication protocols for commercial and agricultural vehicles

The main screen of the software gives you instant access to several protocols enabled on your tool, as well as to the best diagnostic systems. When you click on the desired button, the screen is replaced by a detailed list of vehicles and you can start working immediately.

Recovery and Automatic Functions

KESSv2 doesn’t waste your time: before beginning any writing to a file, KESSv2 corrects the Checksum, checks and removes errors in the ECU, tests battery tension, perceives whether there is the risk of losing injector codes and saves them, and only then starts the writing. You made a mistake? The Recovery function allows you to reset the ECU completely.
