What is the Slave version?

The Slave version requires cooperation with a Master account - this is a model in which:

2. Master (e.g. our team) prepares the modification (Stage 1, DPF OFF, AdBlue OFF etc.).

3. You receive a calibrated file that you upload back to the controller.

You don't edit maps yourself - the entire process is fast, safe and based on proven calibrations.
