Key Terms:
A list of acronyms and abbreviations are defined below in order to help you more clearly understand the menu operations, functions, and
components available on your Auto Meter Boost Controller:
BGD – Bar Graph Display. This is the curved, multi-color, LED radial display used to indicate how much vacuum or pressure the MAP sensor
senses.
SSD – Seven Segment Display. This is the digital numeric display that indicates your current pressure reading. This display is also used to help
you navigate and make changes to your settings.
Duty Cycle – The duty cycle is the percentage that the boost solenoid is turned on. This percentage is different for every application. The
percentage is based on the wastegate spring pressure, exhaust pressure, and boost level. We recommend starting with a 20% duty cycle and
increasing the percentage slowly until the desired boost level is reached.
There are several features provided by your Auto Meter Boost Controller. Use the MODE (-) button to navigate through the following options in
order
• Boost Mode – SSD will display " "
• Peak/Recall – SSD will display " "
• Duty Cycle – SSD will display " "

- High/Low mode. The Mac solenoid will be energized at either of two set duty cycles. Pressing the HI/LO button toggles between the high
and low duty cycle settings.
- Boost by RPM. The boost solenoid will be energized at a duty cycle that has been set for each 500 rpm band.
- Boost by gear. The boost solenoid will be energized at a duty cycle that has been set for each gear.
Press the mode button until " " is displayed and then press Select.. The display will show the highest boost pressure measured by the gauge.
To clear this setting, press Hi/LO while the gauge displays the peak pressure. Press the Select button to clear. Press the Mode button to save the
