buttons FORD MUSTANG 2012 5.G Boss 302 Supplement Manual

The gauge will return to real time mode if no buttons are pressed for
four seconds. Peak g-forces are displayed as shown below.
•PAC - Peak Acceleration g Forces
•PdC - Peak Deceleration g Forces
•PLG - Peak Lateral Left g Forces
•PrG - Peak Lateral Right g Forces
1/4 mile mode:To enter 1/4 mile mode, do the following:
1. Press MODE until “9tr” is displayed.
2. Make sure the vehicle is at a complete stop at the beginning of your
course, then press ENTER to confirm.
3. The display will show “CAL” to indicate mode has been entered. Do
not move your vehicle while the gauge displays “CAL” or you will get
false readings.
4. Begin your 1/4 mile acceleration when the gauge lights the LED bar
graph and the display reads “Go”.
Note:If you have reaction time turned on in the Setup mode, the display
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.
•To review your results again, press B. The gauge will display your
reaction time, elapsed time, 1/4 mile speed, and peak G’s.
•To save your results as your new best, press A to display SAVE, then
press B to confirm.
Note:Saving a run as your new best run will overwrite your previous
best run. The gauge will automatically save/overwrite your stored last
run each time you make a new pass.

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.

Display on/off:
This allows the customer to turn on/off the performance gauge LED bar
graph and seven segment displays. To enable Display on/off,
simultaneously hold down buttons A and C to turn off the display. The
gauge will display “DOFF” before turning off the display. To exit Display
on/off, press any of the three front panel buttons. The gauge will then
momentarily display “DON” and then enter the Real time operating
mode. The LED bar graph and seven segment display will be turned off.
The Ford oval will be illuminated during display off.
