Getting Started - Step 1
Update Your Programmer
Regularly use the aFe internet update software to check
for updates. The software can be downloaded at
www.afepower.com. With the click of a mouse, your program-
mer is up-to-date with the latest software and calibrations.
Included in the update are the vehicle manufacturer’s most
recent calibration as well as feature and safety updates.
Follow these steps:
You will need to be connected to the internet and running Windows XP/2000,
Vista or Windows 7.
1. Download Easy Update software at www.afepower.com.
2. Run the setup program.
3. Once installed, run the Easy Update software.
4. If necessary, create a new registration account or login into your existing account.
5. Update your programmer.
Try this if you have trouble updating your programmer:
• Use your computer’s rear USB ports for optimal power
• Close extra programs to maximize resources
• Avoid wireless connections to minimize interruptions
• Avoid running laptops on battery during updates

Getting Started - Step 2
Plug Your Programmer into the Vehicle’s OBD-II Port
Locate your vehicle’s OBD-II port, then insert the Programmer’s OBD-II cable.
Your OBD-II Vehicle Port is usually located under the drivers side dash as shown here.
Do not remove the programming
cable during any programming sequence.
If you do, the vehicle may not start. A
Scorcher programmer is designed to
automatically go into Vehicle Recovery
Mode and if this occurs, it will return
your vehicle to factory stock. Contact
Tech Support for assistance
at 951.493.7155.
Helpful Hint
During quality control testing, engineers have noted diagnostic ports with worn or loose
connections creating the potential for power to be lost to the programmer. If this happens, the
programmer will go into recovery mode and return your vehicle to factory stock. Contact Tech
Support for assistance at 951.493.7155.
When programming your vehicle, use care not to bump, move or wiggle
the cable when it is plugged into the diagnostic port.

Helpful Hint
Helpful Hint
Measure from the
ground to the top of
your tire. Place a ruler or
flat level item on the top
of your tire to measure
accurately. Measure
in ¼ inch increments
rounding up.
Increasing the height of your vehicle
raises the center of gravity and can affect
stability and control. Use caution on turns
and when making steering corrections.

Returning to Stock
The service center might reprogram your vehicle with an updated program without your knowledge. If
you did not use an aFe Power programmer to return your vehicle to factory stock and your vehicle is
reprogrammed by the service center, the programmer will no longer be able to program your vehicle.
Before taking your vehicle to a service center, return the vehicle to factory stock.
The first time you program your vehicle, your factory stock tune is saved into the
programmer. Once your vehicle has been programmed, you may return it to the
factory stock settings at any point.
Select Tune Vehicle

Select Quick Tune
Press OK
Select Factory Stock
Press OK
Follow on-screen prompts.
Switch Ignition OFF/RUN (On) as requested

PAGE 17
Engine Diagnostic Tool
If a DTC persists, this could indicate a vehicle
malfunction or problem condition. Be sure to return
the vehicle to stock prior to taking it in for service
to address the issue.
Helpful Hint
Use the Engine Diagnostic Tool to check trouble codes. A Diagnostic Trouble Code (DTC)
arises when a vehicle’s computer detects a sensor failure or a parameter outside a
specific range. Most vehicles will illuminate the check engine light. A Scorcher
programmer will read, identify and let you clear DTCs if desired.
1. Read DTC: Plug your programmer into the OBD-II on your vehicle. Use the
diagnostic tool to read the DTC from the vehicle’s computer. If a code is
present, it will be displayed with a full text description.
2. Clear DTC: If your vehicle displays a DTC, a Scorcher programmer can clear
the code, turning off your check engine light.
