If you use a digital display type, long pressing
the display will bring up a submenu where
you can set the number of places.

Create a custom pid with an equation like

Val{Long Name}+Val{Long Name}

or

[xx]+[yy]

Sorry I can’t remember if single quotes are
needed with the Val{} but long names must
match exactly.

XX and YY are the pid numbers shown in
Torquescan.

I am currently Torque less due to an error
in Google Play error:-11 so unable to give
you the missing data.

I have asked Ian awhile back about adding
the decimal places menu option to the
other display types but not implemented yet.

I wanted to change voltage readings to three
places for mV at the time for the main
process variable.

Edited.
