Mass Air Flow 2
Mass Air Flow (MAF) is the Mass of air entering into the engine. On vehicles with actual
MAF Sensors, there will be two gauges, this gauge and Mass Air Flow 1. Mass Air Flow 1 is
the raw output from the MAF sensor, whereas Mass Air Flow Sensor 2 is the calibrated
version used by UltraGauge to calculate MPG.
The Mass Air Flow is calculated for vehicles that do not have a MAF sensor but rather use a
MAP (manifold absolute pressure) sensor. In this case, MAF is calculated by monitoring
several engine sensors, such as MAP, RPM, Vehicle Speed and others.

Zero Oil Distance.
By Default the Oil Distance alarm is
enabled and set to 3000 miles.
Service
Intended to track service intervals such as 15K, 30K or 60K mile service intervals.

General
Primarily used to calculate Average Miles per Gallon. Normally an internal value, but made
available to aid in understanding the Average MPG Calculation. Average MPG is found by
dividing General Distance by Gallons used, where Gallons is “Gallons – general”.
