Alientech K-Suite Software

Next generation software

The first time you use K-TAG you realize 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. The included K-Suite software, helps you by selecting the vehicle or the ECU you want to tune and provides you with access to the up to date manuals for each protocol. You never have to worry about the checksum correction or the proper procedure of connecting to the ECU.

Innovative protocols

Unlike many ECU programming tools, with K-TAG you have at your disposal only the applications you really need. Once you have the hardware, you can choose which group of protocols to enable and then start working.
K-TAG can use new communication protocols not only for cars and bikes but also for commercial, agricultural vehicles and marine appplications

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

K-TAG doesn’t waste your time: before beginning any writing to a file, K-TAG 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.
