Linear Logic ScanGauge II Installation And Operation Manual page 8

The information available will vary from vehicle to vehicle. If the
information is not available for a certain gauge, no data will be shown
for it. If the same gauge is selected for more than one position, only one
of them will show data (if it is available). The other positions will show
the abbreviation, but no data.
GAUGE ABBREVIATIONS
The following table shows what the gauge names mean. In some cases,
the unit selection will determine the gauge abbreviation.

This indicates when the oxygen sensor is being
used to control the mixture (closed-loop) and
when it is not (open-loop). It is usually closed
except when the engine is cold or under full
throttle acceleration.
Cost of fuel per mile at this time
highway speeds, this will typically be a few degrees
higher than the outside air temperature. At idle or
low speed, it may be much higher in temperature
than the outside temperature due to the low air-flow
into the engine and the high under-hood
temperatures warming it up.
Water/Coolant temperature.
A vehicle with a 50/50 mix of coolant and water will
not boil over until about 265 degrees F at sea level.
This will be reduced at higher elevations.
This is the fuel pressure from the fuel pump. Very
few vehicles report this.
Fuel consumption rate in the selected units. This is
sensitive to throttle, gear and loading changes.
Shows the amount of timing advance (or retard).
The more advance there is (or less retard), the better
for fuel economy and power. The limit is set by the
octane of the fuel, the intake air temperature, and
the load on the engine. A lower than normal amount
of advance for similar temperature and speed could
indicate too low an octane of fuel is being used.
This is a percentage of the maximum power
available currently being generated. In some
vehicles it is the maximum available at the present
RPM.
Fuel economy in the units selected. This is updated
about every 2 seconds (Normal Rate). This means
that the fuel economy is for the previous 2 second
period. Small changes in throttle position or load will
show almost immediate changes in fuel-economy.
Speed in the units selected.
