DiabloSport Trinity How To: Upload a Custom Tune to Your Predator or Trinity User Manual
Page 4
NOTES ABOUT CUSTOM TUNES:
‐ If you have to go back to the dealer for any reason, OR need to update the tool, make sure to
restore the Original Backup, but bear in mind that it will wipe the tool's memory of the custom
tune and the Custom Tune will have to be uploaded onto the Predator again when you get your
vehicle back.
‐If you select Original Backup (under the Performance menu) as the tune to install it will clear
the tool's memory of any saved Custom Tunes and its copy of your vehicle's stock tune(the
Original Backup), i.e. "unmarrying" it from your car. As long as there is a tune written to the
vehicle, the tool will have a copy of the Original Backup (the original stock tune) stored in its
memory. So in other words, unless you have to go back to the dealer, OR need to apply a
software update to the tool, you don’t really need to restore the Original Backup.
‐When the DS Downloader is asking for the 'matching original backup', it is asking for the copy
of the stock tune that you uploaded, to compare to the Custom Tune*.
*For clarification (and if you're interested), what the DS Downloader does is takes the Custom
Tune, compares it to the Original Backup, writes a differential file to the tool, and installs that
differential file to the tuner. That file is what the tool will have stored in its memory to install on
your vehicle's ECU.
‐You can switch back and forth between tunes (you can use the Modified Stock tune if you want
the vehicle to run and drive like factory) with the Predator and it will stay married to the ECU
(and save the custom tune)
‐Customs tunes can be erased without resetting the tool under the Options menu of the
Predator or Trinity
‐WARNING: Driving a vehicle equipped with a supercharger on the Modified Stock or Original
Backup file will damage your engine!
‐You can still use the Modify Parameters selection to make adjustments to a custom tune:
1. All you have to do is go under PERFORMANCE/select the tune you want to
install/MODIFY TUNE/MODIFY PARAMETERS
2. After the change(s) are made return to the INSTALL TUNE menu with the ‘Esc’ button
and it will write the tune with the adjustments made.
