Gauge Setup (continued)
Pyro 1 & 2
Both pyro 1 and pyro 2 measure exhaust gas temperature. The only
difference between them is the location of the temperature sensor.
Used for defuel level settings, which protect the engine from
heat damage.
Availability and location of factory installed pyrometers vary
according to vehicle make and year. All ’07.5 and newer diesel
pickups that are equipped with OEM diesel particulate filters
also include factory installed pyrometer sensors. For all other
vehicles, pyrometer kits are available for purchase from www.
BullyDog.com. Bully Dog and factory OEM sensors are the only
pyrometers which will work with the GT.
Speed
This option shows the current vehicle speed.
Monitoring this information can help you ensure that the
speed displayed on the GT 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 Temperature
This option shows the coolant temperature.
Used in defuel settings to prevent damage to the engine.
Not available on all vehicles.
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 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) is designed to
work with the RFI to get the most out of your engine.
Transmission Temp
This option shows the transmission temperature.
Used in defuel settings to prevent damage to the transmission.
Not available on all vehicles.
Load

truck is doing.
Timing
This option shows a real-time reading of the timing position as
the truck is running.
MAF
This option displays information from the Mass Airflow Sensor.
Used by the Engine Control Module (ECM) to determine how
much air is going into the engine. The ECM then sends the
correct amount of fuel for optimum engine performance.
Fuel Econ.
This option displays a real-time measurement of the vehicle’s fuel
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.
Fuel Flow
This option displays the amount of fuel being used at any given
time; it is shown as a percentage.
Not available on all vehicles.
Boost
Current turbo boost pressure.
Barometer
Current atmospheric pressure.
Injection Pulse Width (IPW)
The time the injector stays open for each injection event; usually
displayed in milliseconds (ms).
Battery Voltage
This option shows the current battery voltage.
