This video introduces the KESS3 programming tool developed by Alientech. It is used to read and write electronic control unit data through the protocols available for a particular ECU. The video shows the KESS3 kit with its connection and power accessories.

Master and Slave workflow

AutoChip also explains the difference between Master and Slave versions. A Slave user can read and write a file but does not calibrate it independently. The file is sent to a Master service, which prepares the changes and returns it for writing. This arrangement can suit a workshop that performs ECU operations but does not develop calibrations in-house.

The video mentions passenger cars, commercial vehicles, tractors, trucks and motorcycles; available functions depend on the ECU and licensed protocols. In the 2022 video, AutoChip presented itself as an Alientech partner in Latvia.
