To create KESSv2 flashing tool, Alientech team of designers and engineers developed a new tool that interacts with its software in a very simple and functional way: it recognizes 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.

Until now, all OBD programmers were designed in the same way: assembling various pieces to obtain a single tool that can communicate with engine control units of very different features. In this way, however, you have a complex product, on which risks of failure are very high. Overcoming such obstacles requires more than a simple improvement: it requires a qualitative leap.

Next generation software

The first time you use Alientech KESSv2, you realize just how easy and quick it is to get updates, download operating manuals, start reading an ECU, manage tuning 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 Alientech software supplied with the KESS V2 OBD Programmer, helps you choose the car, the bike, the truck, the tractor, or the ECU you want to tune.

Cars, Bikes, Trucks, and Tractors

We know that chiptuning 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. In this page you can find a complete list of vehicles currently supported by Alientech KESSv2.

Recovery and automatic functions

Alientech KESSv2 doesn’t waste your time: before beginning any writing to a file, KESS v2 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.
