hidden value of soot ?

[maskun84]

Hello, i'd like to use app but when i tested my car I haven't "soot mass measured" only is "soot mass calculated"

Look at screen what i marked - on this place I have "nox sulfur charge" ?

How can I change it ? i really need this value of measured soot.

I have engine R4 2.0L EDC, CUNA (Golf 2017r 2.0 TDi 184ps)

It is a pity there is no answer to this issue. I have exactly the same problem?

This isn't an issue, it's simply a choice of parameters to show.

I decided that NOx sulfur could be more useful that Soot mass measured just because the latter often provides implausible negative values, moreover the DPF regeneration process is based on the calculated soot mass value, so for the app operation the Soot mass measured is useless.
Why do you need to see that value?

Same for me with a DDYA engine. What information can we get from NOx readings please? For example, are there min/max values i should keep an eye for? And when?

The Nox value can give you the information that the ECU is triggering a quick regeneration to reduce them. It happens usually when the soot mass isn't high enough to launch the standard regeneration.
Without this value you could see temperatures raising and high post injection values, withou an apparent reason. Seeing the NOx value decreasing, you can understand what's happening.

This was the reason why I decided to add NOx value instead of soot mass measured that seemed to be useless in that time.
