Auto Meter 4381 - Manual (Page 6)

This sets the boost pressure level that causes the led bar graph to reach its maximum. At this level, all the green leds will be lit. If the boost
level exceeds this set value, the green LED’s will all flash to indicate warning. If boost pressure exceeds this limit by 2.5 psi, the boost mode will
change to off, and the boost solenoid will be de-energized to return to wastegate pressure.
To set the bar graph high limit/warning, press the mode button until " " is displayed and then press Select. The current limit will be shown.
Press Select + to increase the limit, press Mode - to decrease the limit, allowing from 0 PSI to 30 PSI. Press HI/LO when the desired limit is
shown. The display will show . Press Mode to save the limit and exit. The new, set limit will flash once on the display. If Select is pressed
instead of Mode, the new setting will be cancelled. The old limit will flash once on the display.
This sets the boost pressure level that causes the Pro Control output to activate. Press the mode button until " " is displayed and then press
Select.. The current value for the Pro Control will be shown. Press Select + to increase the value, press Mode - to decrease the value. Press HI/
LO when the desired value is shown. The display will show . Press Mode to save the value and exit Pro Control value set mode. The new, set
value will flash once on the display. If Select is pressed instead of Mode, the new setting will be cancelled. The old value will flash once on the
display.
This sets whether the Pro Control active state is high or low. Press the mode button until " " is displayed and then press Select. Press Mode
to toggle between and . Press Select to confirm your selection. The display will flash the new setting. Or press HI/LO to exit without
making a change. The display will flash the old setting. If is chosen, the Pro Control output will be switched to ground when the pressure
is less than the Pro Control set value. If is chosen, the Pro Control output will be switched to ground when the pressure exceeds the Pro
Control set value.
This is used with the boost by gear mode. A tachometer RPM signal and a speedometer speed signal are both required. Press the mode button
until "gr" is displayed and then press Select.. The display will show . The vehicle must be in first gear and turning the speed sender. Press
Select to save the first gear reading. The display will flash , indicating the gauge has captured the ratio of speed to rpm for the first gear.
Press Mode to move on to the next gear and repeat the process for each gear. You will need to capture each gear for your vehicle and may
capture up to 10 different gears. To exit, press the HI/LO button.
If the Boost Controller does not see a tach signal when trying to capture gears, the display will show "not" for no tach. If the Boost Controller does
not see a speed signal when trying to capture gears, the display will show "noS" for no speed.
Press the mode button until " " is displayed and then press Select.. The display will show the current units for pressure. Press mode to
change units. If the display shows PSI, boost pressure is shown in psi, vacuum is shown as in. of Hg. If the display shows " ", boost pressure
is shown in BAR, vacuum in cm. of Hg. If the display shows "KPA", both boost pressure and vacuum are shown in kilopascals. Press Select when
the desired units of measure are displayed
If using Boost by RPM mode ( )
Press the mode button until " " is displayed and then press Select. The display will show 0.0. This indicates the lowest rpm band from 0.0 K
RPM to 0.5 K RPM. Press Select. The current duty cycle value for this rpm band will be shown. Press Select + to increase the value, press
Mode - to decrease the value. Press HI/LO when the desired value is shown. The display will show . Press Mode to save the value and exit
duty cycle set mode for this rpm band. The new, set value will flash once on the display. If Select is pressed instead of Mode, the new setting
will be cancelled. The old value will flash once on the display. Press Mode. The display will show 0.5. This indicates the next rpm band from 0.5
K RPM to 1.0 K RPM. Set this and all other rpm bands in the same manner. The highest rpm band set will apply to any higher engine rpm. To
exit set duty cycle mode, press HI/LO when the rpm band is shown.
If using Boost by Gear Mode ( )
Press the mode button until " " is displayed and then press Select. The display will show " ". This indicates the duty cycle setting for first
gear. Press Select to program the duty cycle for 1st gear. The current duty cycle value for this gear will be shown. Press Select + to increase
the value, press Mode - to decrease the value. Press HI/LO when the desired value is shown. The display will show . Press Mode to save
the value and exit duty cycle set mode for this gear. The new, set value will flash once on the display. If Select is pressed instead of Mode, the
new setting will be cancelled. The old value will flash once on the display. On the gear selection screen, press the Mode button to select the
next gear. Follow the same procedure until all of the duty cycle settings have been set for the amount of gears in your transmission. To exit set
duty cycle mode, press HI/LO when a gear number is shown.
