Step 1:
To access the
boost parameter menu
press and hold the
Mode
button and the down arrow simultaneously. The readout will begin to
flash between the parameter and its value, select SP1 by pressing the up or down arrows.
Step 2:
To edit SP1 press and hold the
Mode
button for two seconds. The set point value will begin to flash.
Step 3:
Apply full load to the engine, in a high gear at full throttle. The
Live
boost pressure will be displayed on the readout. Note, the
number that appears will be in bar, psi or kpa, depending on what has been set in the readout parameter, see section 4b for more detail.
Step 4:
To alter the boost pressure, increase or decrease the boost set point value by pressing the up or down arrow until the desired boost
pressure appears on the readout.
Step 5:
To store this value press the
Mode
button momentarily, this will return you to the boost parameter menu. To exit the boost
parameter menu press the
Mode
button again, the e-Boost will display END as confirmation of exiting the boost parameter menu. This will
return you to
Live
Mode
.
Step 6:
Check that the correct Air/Fuel ratio has been maintained once boost pressure is set
Step 7:
Repeat steps 1 through to 6 for SP2 and SP3
Please Note:
-
The e-Boost cannot be used to obtain a boost pressure lower than the standard actuator setting
-
The e-Boost cannot compensate for a drop in boost pressure at high RPM, due to the turbocharger operating beyond its maximum
efficiency, incorrect turbocharger sizing or excessive exhaust backpressure
4e. Sensitivity
The e-Boost has a sensitivity adjustment that effects the way that the e-Boost controls boost pressure. The sensitivity is factory set to 10,
this caters for the majority of turbo applications, however should you feel that the sensitivity requires adjustment it can be set from 0 to 99.
Refer to the table below for more detail.
Sensitivity too low
-
Achieves more boost in high gears
-
Takes longer to achieve boost set point
-
Boost drops off at higher RPM
Sensitivity correct
-
Boost rises quickly and is steady
Sensitivity too high
-
Boost pressure fluctuates, cycles or is not smooth
-
Boost pressure overshoots set point – rises too fast
Note that actual boost pressure will increase slightly with sensitivity.
To change the sensitivity enter the
boost parameter menu
, then scroll to SEn parameter. Press and hold the
Mode
button for two seconds,
press the up or down arrows to change the sensitivity value. Press the
Mode
button momentarily and the sensitivity value will be stored. Press
the
Mode
button again to return to
Live
Mode
.
Alternatively the sensitivity can be tuned live while editing this parameter. Apply full load to the engine, in a high gear at full throttle. The
Live
boost pressure will be displayed on the readout. Note, the number that appears will be in bar, psi or kpa, depending on what has been set in the
readout parameter, see section 4b for more detail. You can now alter the sensitivity in real time, according to the table above.
