Read ECM and TCM it will show as 2 different boxes with a selection that says Read. 

The read process will take about 10-15minutes. 

Once it is read save your file name as "YourName-VehicleYearMakeModel-Original-Read

And you now have access to the file on your ECM and TCM. 

Once you select Write, it will ask you to license the files and select Yes and you will see your available credits and how they will be spent to write the file. 

Now you can write an unlimited amount of times and change your tune file as much as you would like.

I suggest naming your tune file something different everytime you make a change or revision so that way you can go back to the older version of your tune if you need to.
