GT for Hemi Plus
MORE INFORMATION
Changing the Power Level
The power level tunes on the GT for Hemi Plus are based on the octane of the fuel being run in the vehicle. Unlike the GT diesel, this
option cannot be changed On The Fly (OTF), because it is impossible to change the type of fuel being used while you are driving.
There are some times when this setting does need to be changed, like when lling the tank with a dierent octane than previously used
before. Complete the following steps to change the power level tune setting:
1. Make the same preparations and take the same precautions as when you initially installed the tune. See pages 34-36 for more information.
2. Choose Install Download from the Main Menu.
3. Follow the onscreen instructions.
4. Choose Change Vehicle Settings when you are prompted to choose between that option and “Return to Stock”.
5. Continue following the onscreen instructions until the GT indicates that the process is complete.
The illustration below is an example of one of the times during the installation when it is vital that the power is not interrupted and
the tuner is not disconnected from the vehicle:
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 55 for more
information about contacting technical support.
Performance Testing Software
This software allows you to download saved Performance Testing data from your GT (see page 12 for more information) to your com-
puter and display the information as a graph for easy analysis.
You will be able to get graphs and raw Excel data for: speed, RPM, horsepower, and torque. You can print drag racing time slips, save and rename
tests, and download up to 20 tests from your GT at one time.

IMPORTANT NOTE: This option actively reprograms the tune on your vehicle’s engine computer. 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.
