Gauge Setup (continued)

Pyro

Pyro measures exhaust gas temperature. This is used for warning
level settings, which protects the engine from heat damage.

Speed

This option shows the current vehicle speed.
Monitoring this information can help you ensure that the speed
displayed on the GT T+ and the vehicle speedometer match
the actual vehicle speed. Other important numbers, like the
odometer and fuel efficiency, are based on this information.

RPM

This option shows the number of revolutions per minute of the
engine.
This will help you protect your vehicle and improve performance by
watching and ensuring that the RPMs stay within a certain range.

Coolant (Coolant Temperature)

This option shows the coolant temperature.
Used in warning settings to prevent damage to the engine.
Not available on all vehicles.

Throttle (Throttle Position)

This option shows the throttle position measurement – it is
displayed as the percent open.
Used by the Driving Coach to indicate where changes can be
made to driving habits to maximize fuel efficiency.

Intake (Intake Temperature)

This option shows the intake air temperature.
Air temperature affects combustion temperature and engine
performance. Adding a Bully Dog Rapid Flow Intake (RFI) closed
air system will lower this temperature, improve performance,
and increase horse power. The Gauge Tuner (GT T+) is designed
to work with the RFI to get the most out of your engine.

economy, shown in miles per gallon.
Determine when your fuel efficiency peaks or dies to improve
your driving habits and your bottom line when visiting the pump.
