Dyno Chart PDF

Bully Dog is excited to announce support for the 2007-2010 3.8L Jeep Wranger JK on the Triple Dog GT Gas Tuner. The GT will offer Jeep enthusiasts a unique combination of tuning, special features and monitoring capabilities not available anywhere else in the market today.
Wrangler tuned
The engineers at Bully Dog have worked long and hard to give Jeep Wrangler JK owners access to features such as sway bar disconnect in 4Hi (Rubicon), front and rear lockers in 4Hi (Rubicon), TPMS control for on-trail airdown, disabling traction control, idle up and engine fan control. Once downloaded, the GT will also allow speedometer calibration for larger tire size, as well as speed and rev limiters and transmission shift point adjustments. All of these features are available "on the fly", allowing the driver to quickly adjust settings without the need to re-download.

In addition to the standard and premium engine tunes offered for the GT on other vehicles, there is also a JK-specific Off-Road tune included. This tune smoothly reduces throttle sensitivity while increasing horsepower and torque, to allow for better control over uneven terrain.

As a monitoring device, the GT will also allow Jeep Wrangler JK owners to monitor and display engine parameters through the OBDII system, as well as read and erase Diagnostic Trouble Codes.

Tuning Levels:
· OFF ROAD:

11.5 HP, 15.3 TQ, ENGINE FAN TURNS ON HIGH SPEED AT 200° F COOLANT TEMP LEVEL. The off road tune is very similar to the Reg/ Tow Tune power wise. However, to make the tune more effective off road the throttle sensitivity has changed up. Our throttle mapping is less sensitive than OEM tuning at lower throttle % engagement to give off-roaders more control over the actual power that they put to the ground.
· REG/TOW:
11.5 HP, 15.3 TQ, ENGINE FAN TURNS ON HIGH SPEED AT 205° F COOLANT TEMP LEVEL. This tune is great for everyday driving and towing use. Meant for use with regular octane pump gas but any OEM approved fuel will work.
· PREM/SPEED:
15+ HP, 20+ TQ, ENGINE FAN TURNS ON HIGH SPEED AT 205° F COOLANT TEMP LEVEL. This tune is meant to maximize your potential horsepower. A minimum of 91 octane gasoline is required to avoid risk of engine damage.

Download Features: features only available by downloading.
· Speed Limiter: Adjust from 45mph to 200mph.
· Rev Limiter in Drive: Adjust from 5000 rpm to 6500 rpm.
· Rev Limiter in Neutral: Adjust from 5000 rpm to 5700 rpm.
· Transmission shift point: Modify shift points at Wide Open Throttle on an automatic.
· Calibrate Speedometer: Adjust from a tire size of 23.2" up to 45.5".

Special Features: These features can be used with or without installing a download.
· Engine Fan: Turn the engine fan on or off.
Stock Setting: The engine fan will activate its low speed setting if coolant
temp reaches 215° F and its high speed setting will activate at about 225° F.
Press disable to return to stock setting.
GT Gas Setting: Enable the Engine Fan feature to run the engine fan in high
speed mode at any coolant temperature level. Since it works like an On/Off
switch the engine fan will remain on until it is changed back to disable. (This
feature does not take effect until the GT is at the Main Gauge Screen.)
· IDLE Up: Change engine idle when in park or neutral.

Stock Setting: 700 RPM. Press disable to return to stock setting.
GT Gas Setting: 500-1500 RPM. Enable and select a value for the Engine Idle
position. This is a great feature for keeping voltage in the vehicle up while
running auxiliary electronics off of the vehicles power system. Running a winch
would be a prime example of when this special feature comes into handy.
(This feature does not take effect until the GT is at the Main Gauge Screen.)
This feature only works in park or neutral and will automatically turn off as
soon as the vehicle is put into gear. It will automatically turn back on the next
time a vehicle goes into an idle position.

· TPMS (tire pressure monitoring system): Air down to under 10 PSI without a light.
Stock Setting: A stock Jeep will have preset value in the ECM of 30-34 PSI
depending on the vehicle. The OEM TPMS system will allow for a variation in
tire pressure from the stock set level + or - 6 PSI before it throws a light. Press
disable to return to stock settings.
GT Gas Setting: change the stock preset value to an number from 10-60 PSI.
Once that setting is changed the OEM TPMS system will still allow for the + or - 6
PSI variation so tire pressure could be reduced to as low as 4 PSI. FYI: the sensors in
the tires and value on a manual pressure tester will not necessarily match.

· Disable Traction Control: Completely disable traction control, great for off road.
Stock Setting: Enabled. Press enable to return stock setting.
GT Gas Setting: Disabled: Highlight the “disable” button to instantly turn
off traction control. (Upon re-enabling traction control to revert back to stock
settings the lights may stay on the dash until the key is cycled.)

· Sway Bar Disconnect: (Rubicon only) Disconnect the sway bar up to 30 mph automatically, there is no physical installation required.
Stock Setting: Disable for 4WD Low only up to 18 mph. Press disable to return
to stock setting.
GT Gas Setting: 4WD Low, 4WD Hi, and 2WD up to 30 mph. To enable highlight
the enable button and return to main screen, then press the sway bar button
on the vehicle dash. At 30 mph and above the sway bar will automatically
reconnect itself as a built in safety feature. If a vehicle returns to a level below
30 mph the sway bar will automatically disconnect as long as on dash button
is still activated.

· Lockers: (Rubicon only) Engage lockers in 2wd 4wHi and 4wLow, this feature is recommended for those who know how lockers work.
Stock Setting: Lock front and rear diffs in 4WD Low only. Press disable to
return stock setting.
GT Gas Setting: Lock front and rear diffs in 4WD Low, 4WD Hi, and 2WD. To
enable highlight the enable button and return to main screen, then press
the locker button on the dash once for rear and twice for front and rear. Front
locker will automatically unlock above 20 mph, Rear locker will automatically
unlock above 30 mph. Both lockers will automatically reengage (lock) if
vehicle returns to acceptable speeds and the system is still activated.
