KESS3 Master vs Slave Version

As a Master user, you can read the files clearly. This allows you to operate independently in order to remap and reprogram the ECU with modified files.

As a Slave user, only your master will be able to decrypt your files. (Recommended choice for taking the first steps in chiptuning, supported by your Master)

Master or Slave? Buy what you need

The Master version can manage the SLAVE version.

The SLAVE version cannot modify files, it can only read and write files. Only the Master version can modify files.

A single flexible device that can be configured as required. When the tool is initialized, you can choose the mode of operation.

MASTER - The configuration that allows you to edit software calibrations in a completely autonomous way. The read files can be interpreted by your choice of remapping software.

SLAVE: If you are not confident yet or sufficiently autonomous in editing software calibrations, thanks to this mode you can work with a network of trainers who will support you file requirements.

DEALER-NETWORK: If you intend to create your own slave network of tuners, you will have a reliable and easy-to-use tool

If you buy the slave version and want upgrade to Master version, you can just pay for the price difference and get upgraded.
