i am not sure whether i did a wrong configuration or this is a bug:
In big fields of the display (see photo 1), the boost pressure shows a "VAC" when in vacuum, means negative boost pressure. After building boost over 0 bar the "VAC" disappears and i can read the correct ("positive") boost pressure.
PHOTO 1:

But in small fields (see photo 2), only the vacuum/negative pressure is shown. When motor builds boost (for example 0,8bar boost pressure), the display shows "-0.0bar".
PHOTO 2:

Is the boost pressure not shown correctly in the smaller fields?
Would be nice if the boost pressure could be shown also in positive numbers (for example "+0,8 BAR").
Have i done something wrong?
Edit:
Here the explanation what i mean by "fields":
Field B: Boost pressure shows correct, if negative then VAC + Number, if positive only Number
Field 6: Boost pressure is only shown from negative to 0,0 BAR

Thanks
