DiabloSport Trinity How To: Copy Your Original Backup and/or Last Tune Written - Manual (Page 2)

In most cases, the driver will not work until the computer is rebooted. Once you have installed the
DSDownloader, installed the driver program and RESTARTED your computer, you may proceed to the
first step in the instructions.
If you are using a straight serial/serial cable, you don’t have to install a driver program and reboot the
computer. Just install the DSDownloader as described below.
The DSDownloader program
This manages the transfer of information from a computer to a Diablosport tool. Download and run
the installer program in the in the red link titled, “
DS Downloader Installer 2.2.1.7.exe ".
Tips When running the DSDownloader Installer Wizard
1. Microsoft will tell you “The Publisher could not be verified”. This is normal, just click ‘Yes’.
2. Before the install begins, it will also give you the option to Create Desktop Icon. Make sure to check
this box if you want to have the DSDownloader in a convenient place.
3. The DSDownloader will also want to install the Trinity driver program. You can let it install if you
want, or cancel it. It’s not used for the Predator.
4. You can also delete the installer programs from your Desktop once the actual programs themselves
are installed to avoid confusion.
Copying Files:
1. Bring the tuner to your vehicle and write any Performance program to the ECU. This will cause the
tool to automatically make a copy of the vehicle's factory tune and store it in its memory. When it is
finished, bring the tool to the computer.
2. Power up your Predator and connect it to the PC.
3. Launch the DSDownloader from the desktop icon (looks like our logo on a white background).
4. Once DSDL opens up, you’ll see a screen that prompts you to select the Tool Communication
Configurations. Select tool type (Trinity or Predator) and its part number, and then click “Accept
Modifications”.
5. At this point, DSDL will start searching for your tool on the COM ports. Once it finds the tool, you’ll
get a pop‐up that states, "tool was found on COM _ at a baud rate of 115200". Click ‘close’ here to
proceed. NOTE: If the DS Downloader will not connect to the tool, reference the Driver
Troubleshooting at the end of these instructions.
