ALIENTECH KESSv3 ECU And TCU Programmer With LCV OBD & BOOT/BENCH Master Software Activations

Multi‑Mode Programming: Supports reading and writing ECU/TCU firmware via OBD, Boot, and Bench connection methods (direct ECU board access).
Master vs. Slave:

• Master configuration lets you independently read, edit, and write ECU/TCU calibrations.

• Slave requires working with another Master tuner to decrypt or edit files.
  Software Activations: Protocol licenses (such as Car‑LCV OBD, Bench‑Boot, TCU, etc.) are typically required to access specific vehicle protocols and must be purchased and activated in your KESS3 tool.
