Connect the tool through OBD and read the original file inside the ECU or transmission. Once read, the file can be modified with a remapping software like ECM TITANIUM or rewritten via OBD.


There is no Slave without Master.

The difference between the Slave and Master is the ability to access and edit the data read from the vehicle.


The Master system is not encrypted and therefore it is able to save, read and write the file independently, working autonomously.

The best choice to fully control the entire modification process.


The Slave system carries out everything a Master tool can do, with one difference: the file is encrypted.
The modified file is provided directly from your trustworthy tuner.

A professional that decides to start with a Slave system, with the right training and experience, can choose to switch to the Master system whenever they want to.
