This is a guage set to augment the basic instruments in a 2001 Ford Expedition. There are two types of visual styles, simple and complex.

The simpler gauges are a little brighter,

The easiest way to change pages is to tap the lower corners of the screen, I've added controls that are not visibile until pressed.

The first page has six gauges:

1. Intake temp and coolant temp. Pressing this gauge cycles the number at the center of the gauge between these two items.

2. Fuel trims.

3. Fuel use: this shows instant and average fuel use.

4. A clock. Spark advance and vacuum/boost.

The second page has individual gagues that do not change. Short and long fuel trims for banks 1 and 2, a clock, spark advance and boost/vac. Useful for checking all the items at a glance.
