Boss 302 Unique Features
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 when Go is 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.
