It might be selectable under options. I haven't checked yet. Some screens also only show ND or 0 if not being used (such as in regen mode). Each screen block can also be disabled for faster update time if you like. With the real MX OBDII dongle I see no need for that though.

Core functions:
- Display of 12 DPF filter parameters like: soot mass accumulation in the filter, regeneration duration, km traveled and time passed since last regeneration, EGR valve closing, exhaust gas temperatures of inlet and outlet of DPF (Attention: data shown may vary depending of the engine type due to the presence of the parameters into the engine ecu)
- Manual or automatic parameters update
- Display, for all the parameters, of the previous value and the difference between the actual and the previous value (only for automatic update delays different from 0 seconds)
- Ability to exclude one or more parameter to increase the reading speed
- Display of the filter filling percentage before reaching of the filling limit that starts the execution of a field regeneration (standard regeneration controlled by the engine ecu)
- Graphical display, using a progress bar, of the filling percentage value before starting a field or a service regeneration
- Graphical display of the filter status: red filter for the regeneration phase (passive, field or service) of grey filter with different back internal areas depending on the filling percentage value
- Display of extra data: adapter communication error counter, filter filling rating in µg/min, update time of all the 12 parameters, automatic update delay actually selected in options menu
- Notification bar icon to show an active connection and the auto-update process running
