I've got a boot screen done, as well as figured out the units. As you can tell, my AC is broken. The temperature doesn't seem to update quick enough, so I will likely use something else to monitor that. It also now auto switches between vacuum and boost, if its =>0.

What else should I monitor with this thing? Next on the to do list is a switch to toggle between screens, followed by maybe GPS speed?
