Alientech KESS3 Slave – KESS3SS001 KESS3SAF03 12 Months Subscription

Tool Support & Updates: Keeps your KESS3 Slave tool up to date with the latest vehicle protocols, AlientechSuite software updates, and official Alientech technical support for 12 months.

Subscription Renewal: If your existing subscription expired a long time ago (e.g., over a year), this renewal type (KESS3SAF03) is offered at a higher price to “realign” the subscription period.

Slave Version: The Slave tool itself requires a Master tuner to provide tuned files — the subscription mainly enables updates and protocol access, not standalone ECU tuning by the Slave tool.

No hardware included: This item generally doesn’t include the physical KESS3 hardware — it’s a software/activation renewal only.
