⑤ Boost Setting

Settings on CH1～4, EXT, OFF, AUTO/MANU (SET 0.00～2.45/0 ～100) , GAIN 0

～100.

CH1～4: Set the desired boost on each CH.

EXT: Interfacing function with an optional MAP analyzer.

OFF It cancels the boost control function. As a result it operates

only

on the actuator’s operation pressure.

MAP Automatically changes the setting of the boost depending on the

vehicle speed or RPM.

AUTO/MANU Switch-over of Auto and Manu setting of boost control.

SET AUTO 0.00～2.45 hkPa

MANU 0～100 Point type.

GAIN Ratio 0～100

Configures the characteristics of boost lag.

⑥ Selection of Learning Modes at AUTO Mode

here are times the self learning period at AUTO mode does not finish and keeps

over shooting because of high response turbo or vehicles equipped with twin

turbo. In this case, change the self learning method at the AUTO mode.

Press DOWN for 5 seconds and a “RESPONSE” and “KEEP GAIN” will appear on

the screen.

Response:

NORM: Default setting. It is the fastest for the boost to build up.

MILD:

he starting point of boost is the same as NORM, but it is

slightly slower to reach its peak.

SLOW: It is the slowest in the starting point of boost and reaching its

peak; however, it the setting with least boost over shoots

which

leads to faster learning period.

KEEP GAIN It keeps the duty of the solenoid even after the boost reached its

peak.
