The WatchDog can request a variety of data from your engine's computer. Only those parameters that the computer replies to, though, can be displayed. So the type of information will vary depending on the make, model and year of your application.


WatchDog Driving Coach Display

Bully Dog WatchDog Driving Coach Program
  1. This area displays the Driving Coach on your screen. Monitoring this information will give you a good indication of how your driving habits affect your fuel economy and overall engine performance.
  2. In the top portion of the Driving Coach display is the Wasted Energy graph. This shows your deceleration and acceleration in relation to a base centerline. The centerline represents zero wasted energy. If you accelerate or decelerate too quickly, a color bar will extend out from the centerline, showing the energy expended.
  3. Below the Wasted Energy bar is the Driving Efficiency graph. This bar indicates how consistently you are driving. If you bounce back and forth between accelerating and decelerating too often or if you hit the gas and/or brake with a heavy foot, your driving efficiency will be "low."
  4. In the center of the Driving Coach display, you will see three measurements. This is the Average Mileage line. The first measurement is Average MPG. This number is calculated based on all driving activity from setup on, and it represents your overall, average fuel economy.
  5. Gallons shows the estimated total number of gallons of fuel used.
  6. A Grade is given for your overall driving performance, and it is based on the information provided by all Driving Coach indicators. It ranges from "A" for optimal performance to "Epic Fail," indicating the need for a tune-up, as well as a change in driving habits.
  7. The bottom row on the Driving Coach display is the Instant Economy and Trip line, which shows three measurements. The first is Instant MPG. This represents your fuel economy at a specific moment in time and can be used as an instant indicator of driving performance.
  8. Trip MPG refers to the average fuel economy for a certain trip. This cumulative average resets every time that the WatchDog is turned off.
  9. Trip Grade is the grade that you are given to mark your performance for a single trip. This, too, resets each time the monitor is turned off.


When you are parked or idling for a certain period of time, driving tips will pop up on your screen. These are chosen based on your individual driving efficiency and are designed to help you improve fuel economy.


Monitoring Your Engine

Choose from more than fifteen parameters to monitor. Note: Not all of the following are available for all applications.

  • Engine load - no load = 0 percent; maximum load capacity = 100 percent
  • Coolant temperature
  • Fuel rail pressure (for diesel engines only)
  • Turbo boost pressure (pressure generated by the turbocharger) - monitored for safety
  • Engine RPM
  • Speed (mph or kph)
  • Ignition timing (gas engines) or injection timing (diesel engines)
  • Intake temperature - at point where OEM sensor is installed within air intake stream
  • Mass airflow (grams/second) - amount of air entering air intake stream
  • Throttle position - idle position = 0 percent; full throttle = 100 percent
  • Fuel level
  • Battery voltage
  • Barometric pressure
  • Real-time fuel economy
  • Average fuel economy
  • Trip fuel economy

You can monitor up to four parameters at a time, with each displayed along the left side of your screen. To view detailed information about any one of those factors, touch the button next to it, and the large gauge area on the right will display the information for that parameter. You can further customize the gauge to display in one of the following styles: analog, analog with mini-graph, or full graph.

Expert Answers about Bully Dog WatchDog Monitor - Color Screen - Black - BY40402Do you have a question about this Performance Chip?


  • Ability of Bully Dog Watch Dog Gauge Monitor to Correct Speedometer for Larger Tires
  • Because the Bully Dog Watch Dog is a monitor only, it is not capable of programming or changing anything on the vehicle, including the speedometer calibration. However, the Watch Dog does have a speedometer display function that can be calibrated for accuracy, see page # 23 of the owners manual, which I have linked you to. While driving, you would just ignore the speedometer reading on the vehicle and go by the corrected speedometer reading shown on the Watch Dog.

  • Can the Bully Dog Watch Dog Monitor Display Transmission Temperature on a 2009 Ford Escape
  • The monitors that we carry have specific functions for specific vehicles. The parameters that a particular unit can display depend on what information is fed through the OBD II port on the vehicle. My contact at Bully Dog was unsure of whether or not the computer on the Escape will answer the request from the Watch Dog for the transmission fluid temperature. Since the Edge CTS could not display it that is a good indication that the vehicle computer does not allow or cannot display this...

  • Do the Available Programmers Increase Horse Power and Fuel Economy for a 2012 Toyota Tacoma

This means that you will not get any horsepower or torque gains but by monitoring fuel consumption you can increase fuel economy by changing driving habits based on the data presented by a monitor. The BullyDog unit specifically has a Driving Coach program which will help maximize fuel economy...

  • Does the Bully Dog WatchDog Tune the Engine on a 2006 Hummer H3
  • The Bully Dog WatchDog, # BY40402, is a monitor or comprehensive gauge display only. It is not a programmer that will allow you to change the tune of the engine. It allows you to view various parameters of the vehicle performance. At this time there are no programmers we carry that allow you to change the tune on your 2006 Hummer H3. Your best option is actually to visit a local performance shop and get a custom tune for your Hummer.

  • Performance Monitor Recommendation For 2001 Hyundai Elantra

  • Modification Recommendations for a 2005 Mercury Grand Marquis
  • Yes, a cold air intake like part # AFE54-11692 that is confirmed to fit your vehicle will give you additional fuel mileage. The Bully Dog WatchDog Monitor # BY40402 is not a programmer so it will not directly give you better fuel mileage, but it does have a driving coach that can help you improve your driving habits to maximize fuel mileage. This is not a chip or a programmer though and will not provide you with a different tune for your vehicle to run on. We do not offer any confirmed...
