4c. Bar Graph
The e-Boost bar graph can be configured to indicate a pressure between zero and full scale, depending on your
Mode
l this will be either 2.7 bar
/ 40 psi or 4.1 bar / 60 psi. The bar graph has ten segments, seven green segments and three red segments. When seven segments are
illuminated you have reached the pressure that has been programmed in this parameter. The bar graph has been factory set to one bar.
To change the bar graph enter the
user parameter menu
, then scroll to the bGr parameter. Press and hold the
Mode
button for two seconds,
press the up or down arrow to scroll to the desired pressure. Note, the number that appears in this parameter will be in bar, psi or kpa,
depending on what has been set in the readout parameter, see section 4b for more detail. Press the
Mode
button momentarily and the bGr
pressure will be stored. Press the
Mode
button again to return to
Live
Mode
.
4d. Setting Boost Pressure
Boost pressure is determined by the boost set point value. The boost set point value can be set from 0 to 99 and is not directly related to an
actual boost pressure. Boost pressure is set by increasing or decreasing the value of each of the three boost set points. Increasing the boost
set point will result in a higher boost pressure and vice versa.
The boost set point changes the effect that the e-Boost has on the pressure signal going to the wastegate actuator. A boost set point of 0 will
have no effect on the actuator and therefore you will produce standard boost. A setting of 99 will result in the turbo producing as much boost
as it can. Realistically the boost set point will be somewhere in the middle of this range.
The table below is a
guideline
for boost set point values to approximate boost pressures achieved using an
internal
wastegate with a 0.48 bar (7
psi or 48 kpa) wastegate actuator. Please use caution and reduce these values when using
external
wastegates.
Boost Set Point
Approximate Boost Pressure achieved
30
0.68 bar / 10 psi / 68 kpa
40
1.02 bar / 15 psi / 102 kpa
50
1.29 bar / 19 psi / 129 kpa
The e-Boost can store three different boost pressures, we refer to the different boost pressures as set points, SP1, SP2 and SP3. Note, SP1,
SP2 and SP3 are factory set to 30, 40 and 50 respectively. When the e-Boost is powered up it will default to SP1, we recommend that you
enter a boost pressure that is used most often in SP1.
