Alientech KESS3 Slave – KESS3SS001 KESS3SAF02 12 Months Subscription

The KESS3 tool by Alientech is a professional ECU/TCU (engine/control unit) programming and remapping device used primarily by automotive tuners to read, write, and modify software in vehicles using OBD, Bench, or Boot modes. The Slave version works in conjunction with a Master unit — the Master provides the activation/protocol files that the Slave uses to perform actions on ECUs.

The subscription itself enables your KESS3 Slave unit to keep receiving:

• Latest vehicle protocols and updates so you can support new ECU/TCU models.

• Software updates for the Alientech‑Suite tuning software.

• Technical support from Alientech.
