Under Settings, there is an option for Data Logging & Upload. Then Select What to Log. This will bring up the PIDs currently being logged, if any. To bring up the pre-defined list of available PIDs for your vehicle, click on the icon on the top right that looks like 3 stacked tiny squares, and select Add PID to Log.
