Before Installing Ppe Tunes; Preparing Your Vehicle For Tune Installation - PPE Xcelerator User Manual

BEFORE INSTALLING XCELERATOR TUNES
Please read through the owners manual before installing a tune in your
vehicle. Failure to follow the instructions properly can result in a damaged or
disabled PCM.
User MUST ensure that the factory "stock" tune is in the vehicle's PCM before
installing the Xcelerator tune. GM dealer re-flashes are the same as "stock"
factory tune.
Serious engine damage can occur if the Xcelerator tune is installed over a
non-factory / aftermarket performance tune. Such as another company's
tuner. Tune "stacking" is not advised.
WARNING
Do not perform any operations on Xcelerator (except live data diagnostics)
while vehicle is running. The vehicle must be parked and engine OFF.

PREPARING YOUR VEHICLE FOR TUNE INSTALLATION

•
Turn the headlights off to prevent unnecessary battery drain.
•
ALWAYS have ALL of the doors either closed or open the entire time
while installing the Xcelerator tunes until the process is complete. DO not
open or close the doors.
•
All vehicle accessories and electronics using auxiliary outputs must be
disconnected PRIOR to connecting the programmer into your vehicle's
OBD II port. (ipod, satellite radio, cell phone charger, GPS, etc.) These
devices can cause interference when running through the installation
process.
•
Do not turn on the radio, A/C, or heater while installing tune.
•
Unless instructed by the Xcelerator, never turn the ignition key OFF while
the Xcelerator is plugged into the diagnostic port.
•
Do not unplug the Xcelerator while it is installing the performance tune.
•
Do not try to install tune on your vehicle if battery voltage is low. Charge
your battery if necessary.
•
If your vehicle is attached to a trailer, make sure the brake light receptacle
outlet and plug are disconnected.
