AU (Auxilary output)
The e-Boost2 has an auxiliary output function designed to control an auxiliary device once a certain boost pressure or RPM value is
reached i.e. water spray, water injection, warning light or nitrous controller. This circuit can be used to control a resistor type
automotive relay with a maximum current draw of 2 amps.
There are four options bOn, bOF, rOn and rOF. The boost setting on (bOn) and off (bOF) value will be entered in the units that are
currently selected for display. Between the bOn and bOF values the auxiliary output circuit will be closed and therefore will switch the
relay on.
The RPM setting on (rOn), and off (rOF) are entered as RPM x 100 e.g. if 5000 RPM is the desired setting the user will input 050.
Between the rOn and rOF values the auxiliary output circuit will be closed.
If the bOF or rOF is set to zero there will be no off and the circuit will remain closed until boost or RPM drops below the rOn or bOn
value. If using a boost setting only to switch the relay the RPM parameter values should be set to zero to turn off or vice versa.
If using the auxiliary circuit as a nitrous controller, you can enter all four user definable parameters bOn, bOF, rOn, and rOF. The
auxiliary circuit will be closed when boost and RPM fall with the window created by these four parameters. That is when boost pressure
is between bOn and bOF AND when RPM is between rOn and rOF.
LE1/LE2 Shift/warning lights (LED 1/LED 2)
The e-boost2 has 2 LED outputs that can be used as shift lights or boost level warning lights. These LED outputs can be configured to
turn on and off at any boost pressure or engine RPM. Within the LE1/LE2 menus there are 5 parameters bOn (Boost pressure on), bOF
(Boost pressure off), rOn (RPM on), rOF (RPM off) and rFL (RPM flashing).
Between the on and off values the LED will be illuminated. If the bOF or rOF is set to zero there will be no off and the LED will remain
illuminated until boost or RPM drops below the bOn or rOn value.
You can also set a flashing warning RPM value rFL (RPM flashing) at which the led will flash until rOn is reached. Once rOn is reached
the LED will turn on solid. rFL must be set to an RPM less than rOn. Setting rFL to zero will disable the flashing output.
Boost values are entered in the units currently selected for boost pressure display. RPM values are entered as RPM x 100 e.g. if 5000
RPM is the desired setting then input 050. If using a boost setting, RPM values should be set to zero to turn them off. If using a RPM
setting the boost parameters should be set to zero to turn them off.
The four wires associated with these two outputs are wired into a 4 pin plug located beside the main harness 8 pin plug. A single or
double LED accessory kit is available from Turbosmart that plugs directly into the eboost2 LED output with no additional wiring
necessary.
If rOn, rOF, bOn and bOF values are entered on 1 LED, the LED will illuminate only when the RPM set points have been reached. The
boost values are redundant.
AL (Audible alarm)
The e-Boost2 has an audible alarm function that sounds the internal buzzer once a certain boost pressure or RPM is achieved. The
audible alarm is factory set to 15 psi (1 bar or 100 kPa) but can be programmed for any boost pressure or RPM. Within the AL
parameter there are four options bOn, bOF, rOn and rOF.
The boost setting on (bOn) and off (bOF) values are entered in the units that are currently selected for display. Between the bOn and
bOF values the buzzer will be activated.
The RPM setting on (rOn), and off (rOF) are entered as RPM x 100 e.g. if 5000 RPM is the desired setting then input 050. Between the
rOn and rOF values the buzzer circuit will be closed.
