3. P."eset Boost Dnty Setting
Although this unil uses feedback management and the selflearning function to
automatically control the boost pressure to the specified setting. the valve driving power duty
must stay within a certain limit. Since this limit varies
from
vehicle to vehicle depending on engine
tuning,
it
is
llecessary to set each and every individual vehicle.

3.
Once the LED'S are turned on:
Ihis
shows that the boost control management
is
OFF making
the boost pressure only rise to the factory setting controlled
by
the factory actuator operation.
4.
Drive the vehicle with the power OFF. At this point, attempt to drive in the gear with the
highest load and check the peak boost level.
5.
Normal actuators may range' from 0.4-0.8 kg/cm2. The higher the boost level, the lower the
duly cycle that
is
needed to reach the same boost level.
As
for the actual duty setting, the
fundamental rule
is
if
the boost setting
is
set for 1.00 kg/cm2 and the actuator pressure
is
0.4
kg/cm2 the limit
is
70% while a 0.8kg/cm2 actuator pressure would denote a
400/0
limit.
Of
course
if
the boost pressure is higher than this the duty limits would be lower and
if
the boost
pressure lower, the duty limit higher.
6. Using the actual driving data as a base, set the duty setting corresponding to the actual boost
pressure.
7.
Press the SELECT switch once again for longer than 3 seconds and turn the power back
ON.

of

As

!CAUTION ( Same
for
actuator and wastegate type)
Although this unit has a RPM separate selflearning function, vehicles maximizing their injectors
by
6200 rpm
will
not be able to lise the selflearning lunction during that period because the unil
uses the injector signal to read the engine
RPM
for the selflearning function. In order to have
more precise boosl control, the solution to this problem is to upgrade to higher capacity·
ir~ectors.
