will change from “CAL” to “trEE” and the LED bar graph will change from
yellow to red. When the graph is fully lit, the display will change to “Go”.
During 1/4 mile mode operation, the gauge will calculate 1/4 mile time
(ET) and speed (mph), reaction time (if activated in the Setup mode), and
peak G’s. The 1/4 mile timer does not start until the vehicle starts
accelerating unless you have reaction time enabled. If reaction time is
enabled, the timer starts whenGois displayed. Accelerate through the
entire 1/4 mile distance in order for the gauge to provide you with results.
During 1/4 mile acceleration, the gauge will display an increasing number
which is your calculated speed in mph. When the 1/4 mile distance has
been reached, the gauge will display “Lrun” (last run) followed by “rt”
(reaction time) if enabled, “Et” (elapsed time), and “SPEd” (speed) at
the end of the 1/4 mile.
The gauge will display results once and then display “Lrun” and flash a
bar graph.

Horsepower mode-Note:This reading will vary from advertised
engine horsepower. It includes losses through the drivetrain and other
factors such as fuel octane, wind, weight, road grade, etc. In order to
obtain the most accurate numbers, it is important that the correct
vehicle weight be stored in the gauge (see Setup section). The gauge has
been preset with the weight preset to 3830 lb (1737 kg) and should be
modified as needed. To select horsepower mode, do the following:
1. Press MODE until “HP” (horsepower) is displayed.
2. Make sure the vehicle is at a complete stop at the beginning of your
course, then press ENTER to confirm. The display will show “CAL” to
indicate mode has been entered.
When the display reads “Go”,
1. Lightly accelerate your vehicle through first gear.
2. Shift between gears at approximately halfway to redline.
3. In second gear, (ideally at 2,000 rpm) accelerate under full throttle up
to, but not exceeding, the engine redline.
4. Let off the accelerator and safely stop the vehicle to view your results
once redline has been reached.
5. The gauge will display your horsepower results. Press B to view your
results again. See the section on viewing best run/last run/etc results.
Setup mode:(There are eight parameters that can be adjusted in Setup
mode).
To select Setup mode, do the following:
1. Press the mode button until “Sup” is displayed.
2. Press the enter button to confirm.
3. Press the exit (C button) to exit setup mode.
Vehicle calibration:
Performing this operation will be necessary in order to obtain correct
readings from the performance gauge while operating in real time mode
and performance modes. The vehicle calibration function allows the
gauge to determine its angle, pitch, and general location in your vehicle,
and to compensate accordingly, allowing you to mount it virtually
anywhere in any position, and still get accurate readings.
To select vehicle calibration mode, enter Setup as described above, then
press the A button until “VCAL” is displayed, then press ENTER to
confirm. “REDY” should display. Bring the vehicle to a complete stop on
a flat and level surface and then press ENTER. “HOLD” will display. At

this point, the gauge is taking a stationary reading. Do not move the
vehicle at this time or your calibration will be incorrect and you will need
to re-calibrate. Next, the gauge will light all LEDs on the radial bar graph
and display “GO”. Launch your vehicle in a manner using moderate,
steady acceleration with a goal of reaching 15 mph in three to four
seconds (with 3-1/2 seconds as your goal). Accelerate forward, shifting
smoothly if necessary. When finished with the calibration procedure, the
gauge will display “DONE” for three seconds and then return to Real
Time mode. Accelerating too aggressively or too passively in the vehicle
calibration mode will result in an in complete or inaccurate calibration. It
is very important while performing the acceleration part of the vehicle
calibration that the vehicle not bounce up and down or move side to
side. During this calibration process, DO NOT spin the tires, slide the
vehicle sideways, powershift, lug, jerk, bounce or turn the vehicle. Doing
so will cause an incorrect calibration, and you will need to repeat the
calibration process. To check your calibration, change your display to
Real Time Lateral mode (see Real Time mode). When you accelerate and
brake in a straight line you should see very minimal if any lateral G force
displayed. If you do, repeat the calibration process as outlined above. If
problem persists, contact Auto Meter tech support for further assistance.
Roll out:This function only affects the 1/4 mile function. Roll out is the
distance that your vehicle travels before the 1/4 mile timer (ET) starts.
With a roll out of zero, the gauge will give you a slower ET reading than
a drag strip timer, as the gauge will start the timer the instant the car
moves. A zero roll out will be the most accurate indication of how long it
takes your car to cover a standing 1/4 mile. Increasing your roll out
distance will decrease the ET readings that the gauge will display as you
are giving your vehicle a head start up to 18 inches before the timer
starts.
To select roll out:
1. Enter Setup mode, then press A until “UL65” is displayed.
2. Press B to confirm. The number displayed represents roll out distance
in inches, and may be adjusted from 0 to 18.
3. Press A to increase the value shown. Press C to decrease.
4. Press ENTER to confirm your setting when the desired roll out value
is displayed.

Vehicle weight:Accurate weight is necessary for the gauge to make a
valid horsepower calculation. The vehicle weight has been preset to
3830 lb (1737 kg).
To enter/modify vehicle weight, do the following:
1. Repeatedly press the MODE button until “SUP” is displayed.
2. Press ENTER to confirm.
3. Press A until “ULBS” is displayed.
4. Press ENTER to confirm. The value displayed is total vehicle weight in
pounds (lb). To increase the value, either press or press and hold the A
button. To decrease, press or press and hold the C button. Weight is
adjusted in ten pound increments and can be set to any value from
500 lb (227 kg) to 8,000 lb (3629 kg).
5. When the correct value is reached, press B to confirm.
6. To exit and return to real time display, press EXIT (C button). A
lower than actual weight setting will result in a lower than expected
horsepower reading. The opposite is true with a higher than actual
weight setting.
Bar graph forward high setting:
The bar graph forward high mode allows you to adjust the G force scale
for forward acceleration as shown on the gauge when operating on the
forward axis in real time mode. For example, if you set the “bGFH” to
1g, when the bar is fully lit on the right hand (acceleration) side, the
vehicle is achieving 1g of acceleration force or more.
To select bar graph forward high mode, enter Setup, then press the A
button until “bGFH” is displayed. Press ENTER to confirm. The current
setting should be displayed, and can be adjusted up and down from .3 to
2.0 G’s using the A and C buttons. When the desired result is displayed,
press ENTER to confirm. The bar graph high setting is preset to 0.7G.
Bar graph forward low setting:
The bar graph forward low mode allows you to adjust the G force scale
for rearward acceleration (deceleration or braking) as shown on the
gauge when operating on the forward axis in real time mode. For
example, if you set the “bGFL” to 1g, when the bar is fully lit on the left
hand (deceleration) side, the vehicle is achieving 1g of force or more
during braking.

To select bar graph forward low mode, enter Setup, then press the A
button until “bGFL” is displayed. Press ENTER to confirm. The current
setting should be displayed, and can be adjusted up and down from .3 to
2.0 G’s using the A and C buttons. When the desired result is displayed,
press ENTER to confirm. The bar graph low setting is preset to -0.7G.
Bar graph lateral setting:
The bar graph lateral mode allows you to adjust the G force scale for
lateral acceleration (cornering) as shown on the gauge when operating
on the lateral axis in real time mode. For example, if you set the “bGL”
to 1g, when the bar is fully lit on either side, the vehicle is achieving 1g
of force or more during cornering.
To select bar graph lateral mode, enter Setup, then press A until “bGL”
is displayed. Press ENTER to confirm. The current setting should be
displayed, and can be adjusted up and down from .3 to 2.0 G’s using the
A and C buttons. When the desired result is displayed, press ENTER to
confirm.
Reaction time:
Enabling this function allows the gauge to test your reaction time while
in the 1/4 mile mode only. With reaction time on, the gauge will perform
a dragstrip “Christmas Tree” start and then measure the time it takes
between when it displays “Go” and when the vehicle starts to move.
•To enable or disable reaction time, enter Setup mode, and press A
until “rEAC” is displayed. Press ENTER to confirm. The display will
then read “on” if reaction time feature is enabled, or “oFF” if it is
disabled.
•To enable reaction time, press A. To disable, press C. When the
desired result is displayed, press ENTER to confirm.
Start G’s:
The Starting G’s setting allows the customer to adjust the sensitivity of
the accelerometer within the performance gauge. This setting affects
how quickly the gauge detects movement of the vehicle when
determining vehicle start time. Too low of a setting may result in false
starts due to engine vibration. Too high of a setting may result in the
gauge not properly detected at the start of the run. The gauge has been
optimally programmed to 0.7 G’s for this vehicle.

DRIVING YOUR VEHICLE THROUGH WATER
The Boss302 has aerodynamic devices attached to the underbody
designed to help control airflow for superior performance. Therefore, the
driver must be especially careful to avoid driving through deep or
standing water. If driving through deep or standing water is unavoidable,
proceed very slowly. Never drive through water that is higher than the
bottom of the wheel rims. Water may enter through the air intake due to
the vacuum generated in the engine. Damage caused by the intake of
water in the engine is not covered by the warranty. Refer toTi r e
informationfor more information.
GROUND CLEARANCE
Because of low vehicle ground clearance, use caution when
approaching curbs/curb stops from the front and rear as vehicle
damage will occur. Additionally, when crossing speed bumps or
driveway curbs, Ford recommends approaching at a very low
speed.
