Predator Reflash
Policy
All DiabloSport
products have a guarantee of
satisfaction. If in the first 30 days from date
of purchase you are not satisfied with the results
the Predator generates in your vehicle, simply
restore the factory tune to your vehicle and return the Predator to the
selling dealer. Pending examination of the tool by DiabloSport, you will
receive a refund from your selling dealer. Under no circumstances will
DiabloSport accept the return of a Predator unit that does not
have a performance tune remaining in it.
The Predator will marry to the vehicle upon
upload of the factory tune and cannot be
reflashed for any reason, back to a
blank tool. This marrying of the Vin#
to the tool is what makes it possible
for the vehicle to be reflashed by GM,
and still be reprogrammed again by the
Predator. Reflashing of the Predator is not
possible without the complete disassembly,
replacement and reprogramming of criti-
cal components of the Predator tool.
Predator Revisions:
In an effort to keep the Diablosport Predator
at the forefront of technology, Diablosport will
offer revisions to the Predator when necessary.
Updates are available via the web or you
can return the Predator for a revision update.
Please contact Diablosport for a Return Mer-
chandise Authorization Number (RMA) and an
address to ship to. Predators shipped without
an RMA number clearly on the outer box will
be refused. The updates will be provided free
of charge. The customer is responsible for all
freight expenses.

Preparing the Vehicle for Performance Tune Installation
Very important!
Do not perform any operations on the Predator
(except real time data diagnostics) while the
vehicle is running. The vehicle must be parked
and engine OFF.
• Always have all of the doors closed while installing the
DiabloSport Performance Tune. Keep them closed until
the process is complete.
• Do not activate any electrical accessories while installing the
DiabloSport Performance Tune. Ensure that there are
no electronic aftermarket accessories wired or plugged
into the vehicle that can cause a substantial voltage drop.
Please contact DiabloSport if you are uncertain about the
effect of devices that are installed on your vehicle.
• Certain cellular phones or radio equipment may also
cause interference. Please remove or turn these
devices off.
• Do not try to install any tune on a vehicle with a low battery
voltage - charge your battery if necessary.
• Never turn the ignition key OFF while the Predator is plugged
into diagnostic port.
• Never unplug the Predator while it is installing the DiabloSport
Performance Tune or the Original Backup.
*Important Note:
All electronic aftermarket add-on parts
can create a potential power draw.
• tachometer • electrical fans
• shift light • audio/video equipment.
• gauges • trailer/ tow accessories.
Any change in voltage during flash programming procedures WILL
interrupt the writing process, and potentially disable the vehicle.
Please disconnect or disable any such add on part.
In the event of such an occurrence, unplug the tool, wait 5 sec-
onds and then plug it back in. The Predator will recognize that an
interrupted writing error has occurred and will automatically install
the original back up. The vehicle will then be in its original state.
Please attempt to locate the voltage draw before the Predator is
used again.
Please feel free to contact DiabloSport directly at any time with
questions related to this process. 561-908-0040
IT IS NOT NECESSARY TO CONTACT THE VEHICLE MANUFAC-
TURER SHOULD SUCH ERRORS OCCUR. ANY AND ALL COSTS
RELATED TO SUCH ACTIONS ARE THE RESPONSIBILITY OF THE
END USER - NOT DIABLOSPORT OR ITS DEALERS.

DiabloSport, the Original Backup must be put back into
your vehicle, as described in the section “Reinstalling the
Original Factory Backup”, otherwise your Predator will
not be accepted by the re-seller. To find out which tune
was last written to your vehicle, go to ‘Predator Options /
Show Last Tune Written’ in the Predator.

What to do if write fails: If for any reason the write process
fails, please ensure that the battery is fully charged, the proper
fuses have been pulled and all aftermarket electronic accessories
are turned off. Then follow the prompts in the Predator to restore
the vehicle back to its original calibration. If this process fails,
please contact us at 561-908-0040. We will need you to be in the
vehicle with the Predator during this process. Please ensure you
are able to do so before contacting us.
Invalid License: This message means that the original backup
that is stored in the Predator does not match the program that is
in the vehicle. The most common cause for this error is when the
performance program is left in the vehicle when taken to a dealer
and the dealer re-flashed the vehicle’s ecu. If this happens, the
Predator will ask to take a new copy of the original backup so
you will have the latest updates as a new backup, once backup is
complete you can use the Predator as usual again.
Could not see Ignition ON: Ensure ignition is turned to the
ON position with the engine not running.
