Engine is running, those are the live RPM readings.

I edited the layout for some sample gauges, these are live:

A:F Ratio, Intake Air Temp, Vacuum, Volts, and MPG.

I plan on getting an android head unit, thus I can install this APP, and have the information on the
radio display.

wish.com has the dongle that comes with fully functional software, from China...
Yep, $6.00 + $ 3.00 shipping. https://www.wish.com/c/598460ef3db35270c9140a78
