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.
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 41 for more informa-
tion.
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 49 for more information about contacting technical support.
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.
