1. Modes & Display Description
1-1. Boost Control Mode
This mode controls the boost pressure and starts once the ignition is turned on. If the unit was
previously in the Control Off Mode, it will remain in that mode when the ignition is initally turned on.
The Boost Control Mode has an A Mode and B Mode which allows for 2 different boost settings.
Input values for each of the following modes to maximize the vehicles boost curve.
˴٨
Off Set Value
˴˴
Setting Range: 0 - 100%. Default Setting: 10%.
As the percentage increases, the boost value increases.
As the percentage decreases, the boost value decreases.
˴٨
Response Value Setting Range: 0-100%. Default Setting: 20%.
As the input value increases, the boost increases sooner; overshooting
and/or unstable boost pressure may occur.
As the Response Value changes, the boost slightly changes as well.
˴٨
Over Boost Value Setting Range: 0 - 250 kPa (0.0 - 36.0 PSI). Default Setting: 80 kPa (11.6 PSI)
The boost can be set to maximize the turbine performance regardless of the
Off Set Value and Response Value. As the value increases, it may over shoot
the Off Set Value Setting.
˴٨
Warning Value Setting Range: 0 - 250 kPa (0.0 - 36.0 PSI). Default Setting: 80 kPa (11.6 PSI)
When the boost exceeds the Warning Value, the warning function will be activated.
˴˴˴˴˴˴˴˴
˴̪
Warning Function This function warns the user of an excessive boost increase by an audible
buzzer sound and a " " sign on the monitor.
The boost pressure will be decreased from the Off Set Value by the percentage
of the set Drop Value.
This function activates when the boost pressure exceeds the Warning Value
for a certain period of time. This function may not be activated if the boost
increases excessively only for a short period of time
.
˴٨
Drop Value Setting Range: 0-100%. Default Setting: 100%.
When the boost pressure exceeds the Warning Value, the boost pressure will
be decreased from the Off Set Value by the percentage of the set Drop Value.

1-2. Control Off Mode
This mode turns off the Boost Control Mode. The boost will return to the factory boost control.
(The boost will be at the lowest value.)
1-3. Display
Normal Display
˴˴
The boost value (kPa or PSI) reads in real time.
Peak Hold Display
˴˴
The maximum recorded boost pressure value appears.

After Image Display The maximum boost pressure value blinks for 3 seconds when the boost
˴˴˴˴˴˴˴˴˴˴
pressure changes from positive pressure to negative pressure.
