How does KESS3 Slave work – the cooperation model with the Master?

The Slave version requires cooperation with a Master account. This makes the tuning process quick and secure:

1. You are reading the original ECU or TCU file.

2. You send it to the Master (e.g. our team).

3. Master prepares the modification according to your specifications: Stage 1, Stage 2, Eco, DPF OFF, EGR OFF, GPF OFF, AdBlue OFF and others.

4. You receive a ready file that you upload back to the vehicle.

You don't have to worry about editing maps, analyzing logs, or risking binary errors. You're working with secure and verified files.
