ECU FORD MUSTANG 2008 5.G Shelby GT500 Supplement Manual

ALTERNATE CALIBRATION
Your Shelby GT500 Power Train Control Module (PCM) strategy contains
a feature to limit supercharger boost pressure and engine speed to 4000
RPM for the first five consecutive miles of vehicle operation or 50 engine
start / warm up cycles. This feature is enabled prior to shipment. If
neither of these conditions have been satisfied prior to customer
delivery, full power will not be available.
MANUAL 6 SPEED TRANSMISSION OPERATION
Using the clutch
The manual transmission has a starter interlock that prevents cranking
the engine unless the clutch pedal is fully depressed.
To start the vehicle:
1. Make sure the parking brake is fully set.
2. Press the clutch pedal to the floor, then put the gearshift lever in the
neutral position.
3. Start the engine, then press the brake pedal and release the parking
brake.
4. Move the gearshift lever to 1st gear, then slowly release the clutch
pedal while slowly pressing on the accelerator.
During each shift, the clutch pedal must be fully depressed to the floor.
Failure to fully depress the clutch pedal to the floor may cause increased
shift efforts, prematurely wear transmission components or damage the
transmission. Make sure the floor mat is properly positioned so it doesn’t
interfere with the full extension of the clutch pedal.
Do not drive with your foot resting on the clutch pedal or use the clutch
pedal to hold your vehicle at a standstill while waiting on a hill. These
actions will reduce the life of the clutch.
Due to the high performance of the powertrain, a certain amount of
noise from the transmission is normal. This noise will be most noticeable
when the vehicle is idling in neutral with the clutch pedal out but can
also occur when driving away from a stop.

Operating at high speeds
Your SVT vehicle is capable of high speeds and is equipped with tires
rated for the vehicle’s maximum speed. Remember to drive safely, obey
all traffic laws and only operate your SVT vehicle at high speeds at
locations equipped and designed to do so safely. Before operating your
vehicle at high speeds:
•Ensure correct tire pressures (seeTiresin this supplement).
•Inspect wheels and tires for wear and damage. Replace any damaged
wheels or tires.
•Do not operate your vehicle at high speeds with more than two
passengers or while carrying cargo.
Wheel lug nut torque specifications
Retighten the lug nuts to the specified torque at 500 miles (800 km)
after any wheel disturbance (tire rotation, changing a flat tire, wheel
removal, etc.).
Bolt size Wheel lug nut torque*
lb.ft. N•m
12x 20 100 135
* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
When a wheel is installed, always remove any corrosion, dirt or
foreign materials present on the mounting surfaces of the wheel
or the surface of the wheel hub, brake drum or brake disc that
contacts the wheel. Ensure that any fasteners that attach the rotor to
the hub are secured so they do not interfere with the mounting
surfaces of the wheel. Installing wheels without correct metal-to-metal
contact at the wheel mounting surfaces can cause the wheel nuts to
loosen and the wheel to come off while the vehicle is in motion,
resulting in loss of control.
IMPORTANT TIRE INFORMATION
Your SVT vehicle is equipped with unique wheels and tires designed to
enhance performance. To continue providing this performance, extra
care must be taken when operating and maintaining your vehicle.

Changing the air filter element
1. Release the clamps that secure
the air filter housing cover.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the air filter housing.
4. Wipe the air filter housing and
cover clean to remove any dirt or
debris and to ensure good sealing.
5. Install a new air filter element. Be
careful not to crimp the filter
element edges between the air filter
housing and cover. This could cause
filter damage and allow unfiltered
air to enter the engine if not
properly seated.
6. Replace the air filter housing
cover and secure the clamps.
