Adding a Vacuum gauge to $0D

[Kitch]

Does anyone know how I could add a vacuum gauge to my dashboard in TunerPro?
I have a formula to convert KPa to "Hg but I don't know how to add it into my ADX?
I assume it would end up in the "values" section of the ADX Editor.

Acquisition -> Edit definition->Dashboards-> add gauge -> Item (Map)->Gauge type (analog or digital)-> color
Acquisition -> Edit definition->Values->Map->Conversion(Tab on bottom )

and then there is a good "help" within tunerpro!

Thanks for the reply.
I've had a look at the help section but I can't figure out how to create a reference for the "X" variable in in the equation.
Say I wanted to use KPa as the "X" variable, how would I reference that?
It also turns out the formula I had wasn't what I wanted either, so I'm not getting very far with this.

My settings have kpa already.

I'd like to create a virtual vacuum gauge in TP where 100KPa = 0" of vacuum, it kind of works opposite to KPa readings (probably not the best description).

My ADX has "MAP" in values as well, just like your screen shots.
How would I reference the KPa shown there? Does the packet offset setting reference the value used for KPa or the KPa calculation?

Vacuum needs to have Baro included in the calculation. Needs to use Baro as the Zero vacuum point and then subtract current map. So if the baro is 95 KPA and you are running at 45 KPA you have 50 KPA of vacuum. So Baro and subtract current MAP gives you vacuum. You can then convert KPA to in/hg if you desire.
