KESSv2 is Alientech’s earlier diagnostic-port ECU programming tool. It uses K-Suite software to select a vehicle or ECU and access supported protocols and manuals. Depending on the application, an original calibration may be obtained by a virtual read rather than read directly from the ECU.

Working with it

Check the exact ECU, available read and write functions, cable and enabled protocol in K-Suite. It was offered in Master and Slave versions; a Slave works with its linked Master for file preparation. K-TAG is the companion direct-access tool, and KESS3 is the later combined platform.
