The BitBox slave tool allows reading and writing of the ECU through CAN bus or K-line.

Being a Slave tool, this version needs to link to a Master tool in order to receive a modified file. However, once the modified file is received, the BitBox Slave tool can install it in the car.

The process is as follows:

The BitBox Slave tool can read the stock file. As soon as the stock file readout has been completed, the Slave tool will offer you an option to send a request to a Master tool. Owner of the Master tool develops the tuning file, uploads it and you receive it on your Slave tool.

At this point you will get an option to press Write on the Slave tool, select the file you want to write into the ECU. It is important to note that once this process has been completed, that particular file is marked as USED and it cannot be reused again on a different vehicle.

Another benefit of the BitBox Slave tool is that all Slave tools have access to all the modules that the owner of the Master tool has purchased, so there is no need for a Slave owner to buy additional modules.
