DAT files can be uploaded and inturn put onto your esc. So this file you are requesting is only a view file. I would rather have the DAT but now its a choice.
Robert,
the CSV files are the actual log files from AFTER a flight, showing the current rpm etc,, as I recall, so its logical that they are read only,,showing the results of tweaks you made on the ESC
the dat files are the ESC settings files that allow you to tweak the ESC,
