# What's the cost to use IXI?

To get started using IXI you just need to create an ID Session. Once your car is connected, choose your Tuner and arrange the terms of payment with him for the requested file through a separate channel. When you’re ready, the Tuner must purchase an upload bundle of 1, 5 or 15 editable files according to the job on hand and then upload the modified file to the Session ID. This file can then be downloaded and written via OBD back into the vehicle.
Otherwise, if you are skilled enough, you can also edit the files yourself and upload them in the Tuning Suite. There is no subscription fee for this option but you need to purchase an upload bundle for each file you wish to write with IXI.
In cases where a project can involve more uploads it is more convenient to purchase multiple bundles.
