5. ADVANCED SET-UP
5a. Setting Gate Pressure
Gate pressure control is a unique feature to the e-Boost. The Gate pressure function allows you to determine the pressure at which the
wastegate begins to open. By optimising the gate pressure and keeping the wastegate closed as long as possible, your desired boost will be
achieved faster and at lower RPM. Substantial gains in torque will be achieved.
The e-Boost has three Gate Pressure settings that coincide with each boost set point, SP1, SP2 and SP3. This allows you to tailor each gate
pressure to individual boost set points in order to get the most efficiency from your turbo. For example GP1 is used only when SP1 is selected,
GP2 is used only when SP2 is selected and so on.
The Gate pressure should only be set once your boost set points have been finalised – do not attempt to set the gate pressure first. The three
gate pressures have been factory set to 0.2bar (2.9psi or 20kpa). The objective when setting gate pressure is to maximise the value without
causing a boost spike. Increase the gate pressure until the boost pressure overshoots the desired setting. This boost spike is a result of the
wastegate actuator being held closed too long. Reduce the gate pressure value until this boost spike is eliminated.
If the gate pressure is set beyond your actual boost pressure, the e-Boost will reach the gate pressure once and then revert to your actual
boost pressure. Once the e-Boost registers a vacuum, the gate pressure function is reset and so on. This cycle maybe advantageous for certain
applications where a momentary spike in boost is desired.
To change the gate pressure value enter the
boost parameter menu
, then scroll to GP1, GP2 or GP3. Press and hold the
Mode
button for two
seconds, press the up or down arrows to change the gate pressure value. Press the
Mode
button momentarily and the gate pressure will be
stored. Press the
Mode
button again to return to
Live
Mode
.
5b. Auxiliary Output
The e-Boost has an auxiliary output function designed to control an auxiliary device once a certain boost pressure is achieved, i.e. water spray,
water injection or warning light. This circuit must be used to control a relay, with a maximum load rating of 1amp. The auxilary output is factory
set to 1 bar (14.7 psi or 100 kpa).
To change the auxiliary output value enter the
user parameter menu
, then scroll to the Au parameter. Press and hold the
Mode
button for two
seconds, press the up or down arrows to set the desired auxiliary 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
auxiliary pressure will be stored. Press the
Mode
button again to return to
Live
Mode
