DiabloSport Predator Revision Update User Manual

Revision Update Instructions- Using Legacy Connect

Some older versions of Predator software cannot be auto detected by the DS Downloader.
Any tool with a revision starting with 7rxx and some older 8rxx revisions will fall into this
category. Any tool with a 9rxx revision will auto connect, and should not require legacy
connection (but it can still be utilized if you desire). If your tool requires Legacy connection,
follow these steps. Also for use if your tool displays “Application is Missing or Corrupt”

PREP:

You Need

USB/Serial Cable and Power Source #U7778 OR Serial/Serial Cable and Power Source #U7777 (For

new computers that only have USB ports) (Win-XP computers that have a serial port)

Downloading the Software

1. Driver Program

If you are using a USB/Serial cable (PN U7778)

The Driver program allows the tool to communicate to the computer through the data cable.
You can either run it off of the disc that came with your USB/serial cable kit, or download it at

www.diablosport.com/drivers (the version posted here works best with Windows 7 and

Vista)

a. Download the file to the Desktop folder by right-clicking the red link titled USB to Serial

driver (PC Interface kit driver) (exe file) and selecting “Save As”. Once downloaded, click

the new icon on the Desktop to begin the Install Wizard.

b. Follow all the prompts through the Install Wizard, and restart the

computer after clicking the Finish button.

If you are using a straight serial/serial cable (PN U7777)

You don’t have to install a driver program or reboot the computer. Proceed to STEP 2.

2.The Update File

a. Go to http://www.diablosport.com , click Support, then Docs and Instructions

b. Then, enter Vehicle Type or Predator Part number (U71##):

c. This will take you to the page containing all the pertinent files for your Predator. Scroll down to

the Downloads heading, and under the first heading of Predator Updates, download the latest ‘Crom’
update for your tuner and save it to the Desktop folder. The filename of the update will vary

depending on your Predator part number and revision, but they always contain the Predator part
number and end in “.crom”

Tip: Make sure to download all files by right-clicking the red link and selecting “save

as”, then put the file on the Desktop before hitting “save”.

3. The DS Downloader Program

a. Download and run the installer program in the link titled, “DS Downloader Installer”:

Tip: As you did with the update file, make sure to download the file by right-clicking

the red link and selecting “save as”, then put the file on the Desktop folder before

hitting “save”. You can then double-click the new icon on your desktop to run it:

b. The DS Downloader manages the transfer of information from a computer to any Diablosport tool. It
is also used if you would like to make copies of a tune, or load a custom tune onto the Predator. Follow
the prompts on the Setup Wizard to install it.

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. After agreeing to the terms, the DSDL Installer will ask you to Select the Destination Folder,

and it will default to here:

Just continue through it, unless you want it to go to install in another folder.

3. The DSDownloader will give you the option to install the Trinity driver program. The

Trinity driver program is not used for the Predator, so you can uncheck that box if you
don’t own a Trinity.
