2001-2010 DURAMAX HOT+2 E.T. RACE XCELERATOR
Designed to be used with PPE’s (or any) stand alone harness. If you
want the ultimate in “Program Power,” then you want the PPE Hot+2 E.T. Race
Xcelerator. The agship of the PPE line of Xcelerator Programmers, the Hot+2
E.T. Race Xcelerator is for those individuals who want the ultimate in racing
calibrations and control over your engine’s operations. The Hot+2 E.T. provides
six power levels of additional horsepower and torque and the ability to tune for
any scenario. That means an unreal 425 hp and 620 lb. ft. of torque increase
with a few simple keystrokes! This is the tuner for those who have it all on their
engine and want to get the most from those additions. The PPE Hot+2 E.T.
Xcelerator enables you to add huge power, and also remove transmission torque
limits which eliminates defueling for full power and aggressive up shifts. All of
which drastically improves elapsed times. Speaking of racing, the programmer
allows for the use of all specially formulated racing diesel fuels that are required
when participating in a particular sanctioned racing event. How about adjusting
the Speed Limiter or raising the rpm limit? No problem. Those are just some of
the choices you have with the Xcelerator Hot+2 E.T. For maximum performance
adding a Dual Fueler, racing cam, ported heads and a turbo upgrade are highly
recommended.
FEATURES:
- Eliminates the need for a body control module
- Disables ignition key security (engine will start and run in any
application)
- Engine will start and run in any hot rod/race or marine conguration
with or without a transmission
- Transmission reset and quick learn feature for faster transmission
relearn
- Speedometer corrections (for tire sizes from 27” through 44” at
¼” increments)
- Adjustable speed limiter (from 40 to 200 mph in 1 mph increments)
- Increased rev limit from 3,200 to 5,000 rpm
- Adjustable gear ratio from 2.73 to 5.13
- Read real-time date (for engine diagnostics and code clearing)
- Not compatible with emissions controlled vehicles
- Allows for the use of all specially formulated racing diesel fuels as
required by a particular sanctioned event
- Removes transmission’s torque limiting defueling for full power
aggressive racing up shifts which improves dragm strip
elapsed times
- These controllers will not operate any of the production gauges.
Aftermarket gauges are required.
- The vehicle’s factory air conditioning is disabled by the controller
- For best power, we recommend also installing a high-ow exhaust
that is 4 inch or larger

Xcelerators Owner’s Manual
Please read through the owners manual before installing tune in your vehicle,
failure to follow proper instructions 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-ashes 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.
WARNING
Do not perform any operations on Xcelerator (except live data
diagnostics) while vehicle is running. The vehicle must be
parked and engine OFF.
BEFORE INSTALLING XCELERATOR TUNES
• Turn headlights o󰀨 to prevent unecessary battery drain.
• Always have all the doors closed while installing the Xcelerator tunes, and
keep them closed until process is complete. (windows can be down before
starting installation if ventilation is needed)
• All vehicle accessories and electronics using auxilary 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 stereo, A/C, or heater while installing tune.
• Unless instructed by the Xcelerator, never turn the ignition key OFF while the
Xcelerator is plugged in 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 receptical
outlet and plug are disconnected.
