Gauge Setup (continued)

Pyro 1 & 2

Both pyro 1 and pyro 2 measure exhaust gas temperature. The only
dierence between them is the location of the temperature sensor.
These temperature readings are used for defuel and warning level
settings, which can help protect your engine from heat damage.
The 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 lters also
include factory installed pyrometer sensors. For all other vehicles,
pyrometer kits are available for purchase from www.BullyDog.com.

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 eciency, are based
on this information. If the speed is displayed incorrectly on the GT,
it can easily be corrected. See page 12 for more information.

Boost

This option shows the turbo boost pressure.

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 the
optimal operating range for your engine.

Coolant

This option shows the coolant temperature. The temperature infor­mation is used in defuel and warning level settings to help prevent
damage to the engine.

This option shows the throttle position measurement – it is
displayed as the percent open.
The throttle position information is used by the Driving Coach
to indicate where changes can be made to driving habits to
maximize fuel eciency.

Intake

This option shows the intake air temperature.
Air temperature aects 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.

ICP

This option shows the injection control pressure (ICP). The ICP
aects correct fuel injection, and this information is used by the
engine computer to adjust other settings like fuel ow to achieve
optimum engine performance and increase horse power.

Trans Temp

This option shows the transmission temperature.
The transmission temperature is used in defuel and warning level
settings to help prevent damage to the transmission.

MAF

This option displays information from the Mass Airow Sensor.
It is used by the Engine Control Module (ECM), aka: the engine
computer, 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.
This information will help you to determine when your fuel
eciency 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 in gallons per hour.

The following gauge options are provided to allow the GT to

Performance Testing

This feature oers drag racers the ability to complete the 1/4 Mile and 0-100 KPH performance tests.

You can also download saved tests from your GT to your computer and analyze it using the Bully Dog Performance Testing Software. The software
is available by free download from www.bullydog.com. See page 36 for more information about the Performance Testing Software.

SPECIAL NOTE: Street racing is illegal and extremely unsafe. The performance testing feature should only be used on a sanctioned 1/4 mile drag racing track.

There are two dierent styles available for both tests. The GT will show dierent test screens based on the style of test that is currently
selected in the Performance Testing Setup Menu.

Speed Sensitive Performance Test

Once this test is begun, the GT will show instructions to the user to rst bring the vehicle to a stop. Once the vehicle is at zero miles per hour, the test is
ready. The test will automatically start once the vehicle begins to move.

Race Tree Performance Test

Before initiating the Race Tree style performance test it is important that the vehicle should already be at a complete stop. Once the test is begun, the
GT will display a classic race tree on the screen. As soon as the lights on the tree turn green, the GT will begin to record the vehicle’s time. In this style of
test, the GT will not wait for the vehicle to start moving before it starts recording performance data.

0-100 KPH Test.

This option will test the vehicle’s performance until the vehicle has
reached a speed of 100 kilometers per hour, which is about the same
speed as 62 miles per hour.

Special Functions

These options vary from vehicle to vehicle. See page 15 for more information.

Diagnostics

This option reads the Diagnostic Trouble Codes (DTCs) from your vehicle engine. You can also erase these codes from here.

To look up the DTC codes, the following website is very helpful: http://engine-codes.com/

You can also search for more information about DTC codes online using your favorite search engine.

IMPORTANT NOTE: Most DTCs indicate a problem with the engine, not with the tune or the tuner itself. If you want to know if a DTC is being caused by the
GT or not, uninstall the tune and drive your vehicle for about one week. If the DTC comes back, there is a problem with the vehicle and you should take it to
a trusted mechanic. If the DTC doesn’t come back, reinstall the tune and test drive for another week – if the DTC comes back while the tune is reinstalled,
contact technical support. Be sure to have your tuner, vehicle, and a computer with internet access available when contacting technical support. See page
44 for more information about contacting technical support.

50 STATE GT DIESEL

Driving Coach Setup

The Driving Coach is a special feature designed to be your fuel economy dashboard and information center. It provides real-time visual and audio
feedback about driving eciency and where energy is being lost. The driving coach will help you understand the optimal conditions for your
particular vehicle through real-time observation, giving you the power to maximize your vehicle’s fuel economy.

Two hidden bonuses of driving more eciently are: saving money on fuel and helping the environment!

Before the Driving Coach can give you accurate information, it is important to make sure that the GT is showing the correct speed. In the
sections below, you will nd specic instructions for using the Driving Coach to become the best driver you can be.

Set Economy Goal

This option will allow you to select a fuel economy goal. The Driving Coach will use the economy goal to calculate your driving grade.

It is very important to select an economy goal that is realistic for both your vehicle and the kind of driving you will be doing. If you will be driving mainly
in the city or on the highway, choose a goal that is very close to the advertised fuel eciency for your vehicle in that type of environment. If you will be
doing a mixture, choose an economy goal between the advertised city and highway mileage for your car.

Reset Average Economy

This option will clear the values stored in the GT for the average fuel economy, the number of gallons used, and the grade in the Driving Coach.

Adjust Acceleration

This option will allow you to select the GT sensitivity for the acceleration and deceleration for your vehicle.

Coach Sound Setup

This option will allow you to turn the Driving Coach sounds on or o.

Showing/Hiding the Driving Coach

The driving coach is always running, even if you choose not to have the information displayed. You can show or hide the driving coach on the Main
Display by holding one of the four bottom left buttons until the display cycles through to the gauge style that you want.

11

Driving Coach Setup (continued)

Checking Speedometer Accuracy

First: Change the Gauge Setup to have the Speed displayed on the main display screen. See page 7 for more information about changing the
information displayed on the main display screen.

Next: Go to a safe place with little to no trac where you can perform a speed test. Make sure the speed limit is at least 60 mph. Here are two dierent
ways to nd out your vehicle’s actual speed:

Method 1: GPS

1. Use a GPS device to compare your actual speed and the speed displayed on the Bully Dog.

2. Calculate the Percent Difference by using

this formula:

Percent dierence =

Example 1: A GPS device reads 65 mph and the GT reads 62 mph for one single moment.

GT speed - GPS Speed

GPS Speed

50 STATE GT DIESEL

Step 1. Percent dierence =

Step 2. Percent dierence =

Step 3. Percent dierence = .046 or 4.6% then round up 5%

62 - 65

65

-3

65

Method 2: Stopwatch

1. Use a Stop Watch to measure how long it takes to travel one mile while traveling at 60 mph according to the GT.

Accelerate up to a speed of 60 mph (as shown on the GT)
While traveling at that constant speed, record the amount of time in seconds that it takes to travel exactly one mile.
*Use highway mile markers to ensure that your one mile measurement is correct.

2. Record the time.

3. Calculate the Percent Difference.

If it takes 60 seconds to travel one mile
at 60 mph, then the GT is accurately
reading your vehicle speed.

If it takes 2 seconds more or less than
60 seconds to travel one mile, then use
the formula to the right to calculate the
Percent Dierence.

Once you have calculated the Percent Dier­ence, you can use that information to adjust
the speed display as described below

To calculate the percent dierence use this formula:

Percent dierence =

Example 1: Using a stop watch the actual time it took to drive one mile while traveling at
60 mph according to the GT was 63 seconds.

Step 1. Percent dierence =

Step 2. Percent dierence =

Step 3. Percent dierence =

Recorded Time - 60 seconds

60 seconds

63 - 60

.05 or 5.0%

Adjusting the Speed Display

1. Use one of the methods described in the previous section to determine the exact percentage dierence between the GT and your actual speed.

2. Choose the opposite percentage in the Adjust Speed Display menu.

For example, if the dierence between your actual speed and the speed displayed on the GT was 5%, you should choose -5% (negative ve percent).

50 STATE GT DIESEL

Driving Coach Setup (continued)

Checking Average Fuel Economy

It is important to check the accuracy of the average economy readout on the GT at least once every changing season. There are many reasons to check
and adjust the average fuel economy, here is one example: The fuel delivered to gas stations during the winter contains an average of 1.3% less energy
than the fuel delivered in warmer seasons. That means that the same amount of liquid is going into the tank, but it is 1.3% less eective, on average.
There are many similar factors that aect your fuel eciency that you cannot control and the GT cannot sense or adjust for. That is why it is important to
adjust the fuel economy of the GT every once in a while.

To adjust the Average Fuel Economy displayed by the GT, follow these steps:

1. Go to the gas station and get a full tank of gas.

2. Reset both of the following gauges before driving away from the gas station:

- The Average Economy on your GT.

- The trip odometer on your vehicle.

4. Drive the vehicle for an entire tank (or two)

5. Calculate your vehicle’s average fuel economy by hand using the following equation:

GT Average Economy - Calculated Average Economy

Percent dierence =

Calculated Average Economy

Example 1: Assume the GT Average Economy is 24 mpg and the Calculated Economy is 21.

Step 1. Percent dierence =

Step 2. Percent dierence =

24-21

21

3

21

• NOTE: If the speedometer on the vehicle is not accurate,

then the odometer will also be incorrect. You will need

to be able to calculate the exact number of miles driven

before your next refill.

Step 3. Percent dierence = .142 or 14.2% round down to 14%

6. Use the equation below to calculate the Percent Difference between the average fuel economy that you have calculated and the aver­age fuel economy that is displayed by your GT.

Adjust the Average Fuel Economy

Follow the steps listed below to change the average fuel economy that is displayed by the GT:

1. Go to the Main Menu

2. Choose Vehicle Setup

3. Choose Adjust Economy Display

4. Use the buttons on the right to move up and down the percentages

5. Choose a percent value that is the opposite sign of the Percent Difference that you calculated using the equation above.

- For example, if you determine that the Percent Difference is 14%, you should choose -14%.

13

Vehicle Setup

Select Pyro Source

Choose either factory installed or Bully Dog pyrometers.

Set Defuel Levels

Set the temperature level at which the extra power level settings on your GT are automatically turned o to protect your engine from damage.

NOTE: The defuel option is only available on vehicles that can adjust horsepower levels on the y. For vehicles that cannot adjust power levels on the y, on screen
warnings are available in place of automated defueling.

It is also possible to turn each of these settings completely o. This is appropriate if the sensor for that setting is not available or if you do not wish to
have that setting controlled by the GT.

See the Pyrometer Calibration section on page 36 for help in determining the correct temperatures for the defuel settings:

Adjust Economy Display

Change the miles per gallon shown by the GT.

This setting should be changed if the GT is showing incorrect fuel mileage. See page 12 for more information about how to do this.

VEHICLE SPECIFIC DOWNLOAD FEATURES

These options cannot be adjusted OTF (On the Fly). This means that once they are set during the install download process, they can only be changed by starting that

process again and choosing to Change Settings when prompted by the GT.

The following features are not available for all vehicles. Our engineers are also working to add even more applications, so
check our website for a complete list of which features are available for specific vehicles.

Speed Limiter

This changes the top speed that the car will reach before the engine automatically limits the power needed to go faster.

Calibrate Speedometer

This feature will adjust the speed displayed by the factory installed speedometer on your vehicle. This can be useful to correct an inac­curate speedometer caused by a change in tire size.

Calibrating for any tire size over 35” may cause the on-dash ABS light to turn on.

UPDATING THE GT

OVERVIEW

FAQs about Updating

Why do I have to update my GT?

Because it’s very important! These are just some of the reasons:

1. Vehicle manufacturers regularly change the part numbers and other information that the GT needs to know in order to communicate eectively
with your engine computer. If the GT doesn’t have updated information, it may not work correctly with your vehicle. Bully Dog releases updates
when necessary to keep up with any changes that vehicle manufacturers make and give our customers the best support possible.

2. Our technical support team gathers information about any problems experienced by customers and works with the engineers to x them as soon as
possible. If these xes can help other people avoid similar problems, our engineers include them in the updates that we release for everybody. One
of the most important troubleshooting steps we take when someone encounters a problem is to make sure they have the most recently released
software version. This often immediately xes the problem!

3. Bully Dog engineers are constantly working to expand the features and vehicles that the GT is able to support. Once a new vehicle or option is
unlocked, they make sure it is available to everyone by including it in the updated software version.

Do I have to update my brand new GT?

Yes! There is no way to know how long your particular GT may have been waiting on the shelf for you.

How often should I update?

Updates are released regularly, so you should check for them at least four times a year. A good rule of thumb is to check once
every three months.

It is also a good idea to update the GT if you have uninstalled the tune for any reason, like taking your vehicle in for service. This will
help you avoid any problems during the reinstall if the engine computer has been flashed and has new part numbers (this is very com­mon, even for a routine vehicle service).

What is included in updates?

Updated part numbers and other information from vehicle manufacturers, tested fixes for problems customers may encounter,
and any additional features or support for new vehicles that our engineers have developed.

How can I tell which software version I currently have?

1. Go to the Main Menu.

2. Choose the Show Settings option.

The software version is listed under System Info, next to Version. It is labeled SW.

How can I use the Update Agent to check for updates?

Start the Update Agent application and connect the Micro SD card to your computer using the card reader that came with your
GT. If you have an older model of GT and did not receive a card reader, you can purchase one online at www.bullydog.com. There
are also many local retailers who carry card readers that are capable of supporting the Micro SD card format.

The Update Agent should automatically recognize the Bully Dog device, check the current software, and let you know if an
update is available.

See page 23 if your SD card is not automatically recognized by the Update Agent.

PHYSICAL INSTALLATION

Be sure to check the list and description of included parts on pages 4-6.

Brief Preview

This is a quick list of the basic installation steps. You can find more specific information about each step in the next section.

1. Connect the OBDII adapter plug to the port under the dash.

2. Plug in the power cable to the fuse box and connect it to the adapter plug.

3. Run the HDMI cable under the dash.

4. Mount and connect the GT.

The illustration below shows how to install the power wire if there is no fuse box available inside the cab of the vehicle. If a fuse box is available inside the cab, there

is no need to run the power wire through the firewall into the engine bay.

PHYSICAL INSTALLATION

Detailed Instructions

1. Connect The OBDII Adapter Plug to the OBDII Port. See page 6 for a detailed description of the different parts of the OBDII
adapter plug.

• Find the OBDII port in your vehicle. As shown in the illustration, the specic location of the port can vary between dierent vehicles, but it is always

somewhere under the driver’s side dash. The OBDII port will
have the same shape as the end of the adapter plug.

• Once you have found the port, simply connect the adapter

plug to it.

2. Connect The Power Cable. The power cable is not
really optional if you want to enjoy the originally
designed functions of the GT. It is only optional under
one of the following circumstances:

You do not want to keep the GT permanently installed and
plan on disconnecting it when you are not actively using the
unit.

You want the GT to remain on at all times, regardless of
the eect that this could have on your car battery

You prefer physically switching the GT on and o and do
not want it to automatically power down when you turn

the key to the o position.

OBDll Port Location

All OBDll ports are located under the

dash on the drivers side of the vehicle.

OBDII Plug

50 STATE GT DIESEL

Otherwise, in order for the GT to work as originally designed, it is very important for the power cable to be installed as de­scribed below:

1. Locate an ignition fuse.

• An ignition fuse is one that is controlled by the position of the key.

• Sometimes we call this a “key-on” or “key-o” fuse.

• The fuse that controls the front windshield wiper is usually perfect, but any fuse that turns o when the key is turned o will work just ne.

• Every vehicle is dierent. There is no way to provide wiring diagrams for all vehicles. You will be able to nd the information for your vehicle

in the owner’s manual or online.

• Some vehicles have a fuse box inside the cab. If your

vehicle does not have a fuse box inside the cab, you will
need to locate the re wall and connect the power cable
to the fuse box under the hood.

2. Connect the power cable to the fuse.

• You may have received a fuse tap with your GT. See below

for an illustration and instructions on using the fuse tap to
install the power cable.

• You can also simply put the power cable into the fuse box

along with the fuse that is normally installed in that loca­tion. See the diagram and picture for more information.

• If you did not receive a fuse tap, but prefer to use one to

install your power cable, you can purchase one at your
local auto parts store. Be sure to ask for installation
instructions if none are included with the fuse tap.

Using the Fuse Tap and Spade

1. Find and pull the fuse that you are going to use to insert the GT Power Cable.

2. Slip the fuse tap over the prong on the fuse.

3. Fit the spade over the fuse tap and crimp them together with pliers.

4. Put the tapped fuse back into the fuse box.

PHYSICAL INSTALLATION

Detailed Instructions (Continued)

3. Run the HDMI cable under the dash.

This step helps you install the HDMI cable in a way that is discreet, stylish, and that helps to protect the GT

1. Plug one end of the HDMI cable into the port on the OBDII adapter plug.

2. Run the middle of the cable up through the dash on the driver’s side so that the end of the cable comes out near the A-pillar.

• It may be necessary to temporarily remove the weather stripping and dash panel to successfully hide the HDMI cable under the dash.

3. Make sure that there is enough slack in the cable to connect the GT when it is in the mount.

4. Connect and Mount the GT

1. Install the mount that you have chosen. If you are using the Universal Windshield Mount included with the GT, see the installation instructions
in the next section.

2. Connect the HDMI cable to the GT.

3. Secure the GT to the mount.

Using the Universal Windshield Mount

IMPORTANT NOTE: Safety is your first and most important responsibility as a driver. Safety is also your first and most important concern when placing your GT.

Make sure the GT does not create blind spots or distract the driver.

1. Locate the T-shaped socket on the back of the GT.

2. Place the square top of the Universal Windshield Mount into the square part of the T­shaped socket on the GT.

3. Slide to the left to secure the GT to the mount.

4. Place the suction cup against the windshield and use the lever to secure the mount to the
windshield.

INSTALLING THE TUNE

In order to enjoy additional horsepower and other advantages of tuning your vehicle, you need to use
the Install Download feature.

The process is basically the same when you are installing, changing settings, or returning to stock.

CAUTION! This option actively reprograms the engine computer in your vehicle – if the process is interrupted because of poor prepa-

ration you will have problems which could prevent you from using the GT or even being able to drive your vehicle for a few days.

In order to have the best installation experience possible, it is important to review the instructions and pay close attention to the

preparation steps listed below:

Important Preparation Steps

Choosing an Appropriate Time and Place to Install

Do NOT install if you will need to use the vehicle to get somewhere soon.

DO set aside at least an hour for this part of installation.
Under optimal circumstances the installation can be completed in less than 30 minutes.
If you encounter any problems, you will need at least an hour to resolve the problem.

Do NOT install if the vehicle is in a remote location.

DO make sure that you have access to a phone and a computer with internet access.
DO update the GT online by using the Update Agent before you try to install.
You might need to connect to a computer to get special les from technical support if you encounter problems during the install.

Do NOT install if you do not have a way to contact technical support.

DO make sure that you can contact Bully Dog technical support.
Technical support is open Monday-Friday, 8 a.m. – 5 p.m., Mountain Standard Time.
If you decide to install on Friday evening and encounter problems, you might not be able to use your vehicle until you are able to contact technical
support on Monday.

See page 44 for more information about contacting technical support.

Managing Other Electronics

DO turn o all factory installed electronics inside the vehicle. This includes:

Headlights, heater, air conditioning, stereo, DVD players, etc.
Failing to turn o all electronics can prevent a successful download.

DO disconnect additional electrical appliances. Remove any chargers or electrical devices connected to:

Cigarette lighters, USB ports, or other types of electrical outlets in the vehicle

DO disconnect any other aftermarket electronic device. This includes:

Trailer brakes, stereo, alarm, CB, remote start, DPF delete, Sirius/XM satellite radio, etc.

Any electrical device that was installed after the vehicle was released from the factory.

Disconnect these items from the fuse box, or other power connection. You do not have to completely physically uninstall them; just make sure they
are not getting power.

Note: It is important to make sure that electrical devices are turned off or disconnected as described above during you are installing the GT tune to your vehicle.

Once the download is installed, you can reconnect and turn on all of the electronics that you normally use.

IMPORTANT NOTE: It is not recommended to use the GT with any other electronic tuner designed to increase horsepower.

29

INSTALLING THE TUNE

Important Preparation Steps (Continued)

Make SURE that the Battery is Charged

DO make sure that your batteries are fully charged before beginning any download.

It is a good idea to have a battery charger ready to connect to your vehicle if the batteries begin to lose their charge while you are installing the
download.

IMPORTANT NOTE: It is very important that the tuner is not interrupted while it is writing to your engine computer – if the batteries die and the tune is inter-

rupted, it could prevent you from being able to start your vehicle.

Make SURE the Tuner is Ready

DO complete an online update with the Bully Dog Update Agent.

This is a free application available on the Bully Dog website.

This requires a computer with internet access.

See pages 20-27 for instructions on updating the GT.

DO make sure that the tune has not already been installed.

1. Go to the Main Menu on the GT.

2. Choose the Show Settings option.

3. Check what is showing next to Download

If the GT shows Installed

- Connect the GT to the original vehicle and uninstall the tune.

- If this cannot be done, contact technical support for a reset – there is a mandatory fee for this service. See page 36 for more informa­tion.

If the GT shows Not Installed you can continue with your preparations to install the download to your vehicle.

If the GT shows Recovery, contact technical support for further assistance. See page 44 for more information about contacting technical support.

50 STATE GT DIESEL

UNINSTALLING  RETURNING TO STOCK

What does this mean?

“Uninstalling the tune” and “returning to stock” are different ways to describe the same thing: writing the original (stock)
information to the engine computer so it uses the settings that it used before you installed your GT. Doing this also sends a
signal to the GT to let it know that it is no longer installed on a vehicle, which will allow you to install the tune at a later time.
The GT will not allow you to install if the tune has already been installed on a vehicle.

When to Return to Stock

You should return to stock in ALL of the following situations:

• EVERY TIME you take your vehicle in for any type of service. It is a very common practice for the engine computer to be “ashed” (re­programmed) during all types of service, even routine maintenance. If the tune from the GT still installed when the engine computer is
ashed, it can cause problems when you want to use your GT in the future. See page 40 for more information.

• If you want to install the GT on a dierent vehicle. For instance

If you have a second vehicle and want to try the GT on it. The GT can only be used on one vehicle at a time.

If you want to let a friend try the GT.

If you have decided to sell the GT to someone else.

• If the battery is having problems and could possibly go dead.

• If you need to disconnect the battery for any reason.

IMPORTANT NOTE: If you do not return your vehicle to stock, you may have to call in to technical support to have your GT reset. There is a mandatory fee for this

service. See pages 36 and 44 for more information about the reset fee and contacting technical support.

What if I Don’t Return to Stock?

Here are some common examples:

• If you take your vehicle in for service, they will “ash” the engine computer. Even if you ask them not to, any dealer or shop will do this

automatically – it is standard procedure for any vehicle they see and they really can’t help themselves from following this ingrained
habit. What they are doing is actually writing an updated le over any information that is currently saved in your engine computer. This
includes the tune from your GT, so basically the tune is no longer installed and you will not be able to use the power level settings or any
other options – but the GT doesn’t know that, it still thinks that the tune is saved to your engine computer. Unless you go through the
uninstall process with your GT, it will still show as installed and will not allow you reload the tune on your vehicle or on any other vehicle.
The only way to resolve this problem is to contact technical support and have the GT reset – there is a mandatory fee for this service. See
page 36 for more information about the reset and fee.

• If you sell or trade-in your vehicle you will not be able to install your GT on another one without calling technical support to have the GT

reset. See page 36 for more information about the required fee for the reset service.

• If you sell the GT to another person without uninstalling the tune from your vehicle rst, they will not be able to use it. You will probably

have negative consequences like an upset buyer, having to refund the purchase price or cover the cost of a reset, a negative review, and
bad karma. See page 36 for more information about resetting the GT and the mandatory fee.

By now, you may have noticed a pattern: if you do not return your vehicle to stock and something happens to your engine computer, you
will need to call and pay the fee in order to have the GT reset. Page 36 has more information about the reset process and the required
fee.

33

UNINSTALLING  RETURNING TO STOCK

How to Return to Stock

There are two ways to return your vehicle to stock.

IMPORTANT NOTE: Both methods are very similar to installing the tune to your vehicle, so you should make the same preparations and take the same precautions.

This means choosing a good time and place, making sure the battery is charged, pulling fuses (if necessary), disconnecting aftermarket electronics, etc.

See pages 29-30 for more information.

IMPORTANT NOTE: There are certain times when disconnecting or interrupting power to the GT can interfere with the engine computer programming process.

If the engine write is interrupted, the programming on your engine computer can be corrupted. This can cause your vehicle not to start and possibly even require

the ECM to be replaced.

This illustration is an example of one of the times
during the uninstallation when it is vital that
the power is not interrupted and the tuner is not
disconnected from the vehicle.

UNINSTALLING  RETURNING TO STOCK

How Do I Know if the GT is (Still) Installed?

There are two ways to check if the tune is currently installed:

Main Screen

1. Look at the lower right corner of the main display screen.

2. If there is a box that reads “Power level setting not available until download is installed” the tune is not installed.

• If there is anything else in this part of the main screen, the tune is probably installed. You can double check by using the method described below.

Show Settings Screen

1. Go to the Main Menu.

2. Scroll down.

3. Choose Show Settings.

4. Check to see what the GT shows next to “Download”.

5. If it shows:

• Installed – the tune is still loaded on the engine computer.

• Not Installed – the tune has been uninstalled and the vehicle is returned to stock.

• Recovery – there is a problem and you should contact technical support. See page 49 for more information.

Pyrometer Calibration

What is Pyrometer Calibration?

Pyro calibration is a way to nd the best temperature to use for the GT defueling or warning setting for your vehicle. This will help you
prevent heat damage to your engine.

How to Calibrate Your Pyrometer

1. Return your truck to stock by uninstalling the tune. See page 33 for more information.

2. Find a steep hill with a long road and a high speed limit.

3. Wait for a hot day.

4. Set up a heavy load on your vehicle.

5. Haul the load to the top of the hill.

6. Check the pyrometer temperature.

7. Add 150°F.

8. Change the defuel setting (or the setting to display a warning) to the new temperature.

Reset Fee

Why is This Policy in Place?

In the past, our technical support department has been ooded with people needing to reset their tuners. Because of this, we were not
able to support the other people who needed help. The extra calls were coming for two dierent reasons:

1. Despite our best attempts to educate customers about the importance of uninstalling the tune before selling their vehicle or having it serviced,
people did not remember or did not take seriously the requirement of returning their vehicle to stock and were calling in repeatedly.

2. Some dishonest people were installing the tune on multiple vehicles and calling in to have the unit reset in between each tune. The tuners are
designed to only be installed on one vehicle at a time.

Once the policy for the reset fee was created, the number of calls to request tuner resets was signicantly reduced and we were able to
improve our support to everybody.

The reset process is relatively simple and a technician can help you complete the reset over the phone. See page 44 for more informa­tion about contacting technical support.

FAQS/TROUBLESHOOTING

Engine Warm-Up Mode

Q. My engine is stuck in warm-up mode and I can’t change the power level. What is going on and how can I fix this?
A. This is a feature that we have included with the GT to help people, particularly fleet managers, ensure that their vehicles are

properly warmed up before additional power level settings can be used. In some vehicles, this option doesn’t turn off when it
should, either because the sensor is not present or the setting is too high.

How to fix this problem:

1. Go to the Main Menu.

2. Choose Vehicle Setup.

3. Choose Set Defuel Levels.

4. Scroll down to the bottom of the list.

5. Choose Startup Coolant Temp Level

6. Turn this setting o.

7. Go back to the Main Display screen.

My GT Won’t Turn Off

Q. I have turned my vehicle off and removed the key – everything else has turned off. Why won’t my GT turn off?
A. The power switch on the OBDII adapter plug is in the “wrong” position. If you want the GT to turn on and off along with the rest

of your vehicle, you will need to make sure that the power switch is in the “correct” position and that the power cable is installed
correctly. See page 26 for more information about installing the power cable.

My Vehicle Won’t Start after I installed the Download

Q. My truck won’t start after I installed the download, what happened and how do I fix this?
A. The GT encountered a problem when it was writing to the engine computer. Follow these steps to resolve the problem:

1. Return the truck to stock. See page pages 33 for more information about this step. Test to see if the engine starts.

2. Update the GT. See pages 17-24. for more information about this step.

3. Install the download again. Test to see if the engine starts.

4. Contact technical support if the problem persists. See page 44 for more information about contacting technical support.

FAQS/TROUBLESHOOTING

My Vehicle Won’t Start after Returning to Stock

Q. My truck won’t start after I uninstalled the tune. How do I fix this?
A. Follow these steps to get your truck running with the tune uninstalled:

1. Make sure that you have completed all of the preparation steps on page pages 29-30.

2. Go to the Main Menu on the GT.

3. Scroll down and choose the Show Settings Option.

4. Check what the GT is showing next to Download.

50 STATE GT DIESEL

10. If your vehicle still will not start, contact technical support – see page 44 for more information about contacting technical support.

Note: If the Recovery process completes successfully, your truck is returned to stock. You will not need to do another step to uninstall the tune or return the

truck to stock. If the Show Setting screen still shows Recovery next to Download, contact technical support to have the unit reset

(there will not be a charge to reset from Recovery Mode).

My Vehicle isn’t Listed under Change Vehicle

Q. Why isn’t my vehicle included in the list under the Change Vehicle option?
A. Chevrolet owners should choose the GMC option that matches the year of their vehicle. If your vehicle is very new or very old, it

may not be supported yet.

What Kind of Increased Performance Can I Expect?

Q. How much extra horsepower will my vehicle get? What can I expect for fuel efficiency improvements?
A. See page 2 for information about additional horsepower. Many people do find that the increased horse power helps them

get the most mileage out of their fuel as possible. However, since fuel efficiency varies so much between different vehicles and
drivers, there is no way to accurately predict fuel mileage increases. To get the best gas mileage possible, make sure to calibrate
and use the Driving Coach to improve your driving habits. See pages 11-13 for more information about the Driving Coach.

FAQS/TROUBLESHOOTING

DPF Delete

Q. Will the GT delete my DPF?
A. No. Bully Dog does not offer DPF delete. Bully Dog will never offer DPF delete.

Crazy Larry

Q. Can I get the Crazy Larry tune on my GT?
A . No. Crazy Larry is no longer available. Due to EPA regulations, it will not be offered again.

I Don’t Feel Extra Power

Q. Why can’t I feel the extra horse power?
A. If your vehicle was just returned from the dealer, you might have forgotten to return the vehicle to stock. See pages 33-35

for more information on returning to stock. See page 35 for more information on checking to see if your vehicle was returned
to stock and what to do if it was not returned to stock. If you can’t feel the extra horse power after installing the tune, contact
technical support. See page 44 for more information on contacting technical support.

PTO

Q. What is the PTO option during GT setup?
A. The PTO option is a power take-off option. If this hardware option is installed on your truck, it will allow you to use your en-

gine to provide power to external devices. This option is not available on most vehicles, which is why the GT will most likely only
give you the “No” option during the install process.
