FUNCTIONALITY  
The BOV controller works by detecting a negative voltage change in throttle position. It then energises the solenoid to vent all of the air  
out of the BOV cap, causing a pressure differential between the piston of the BOV and the cap which will vent pressure from the intake  
system. There are 2 parameters that can be adjusted to tune the controller for optimum performance; duration and sensitivity. The green  
LED shows that the BOV controller is on. The yellow LED shows when the solenoid is activated.

INSTALLATION  
Mount the unit away from any heat source and moisture. Wire up the unit as per diagram. Do not connect the unit to a power supply  
which will have a greater voltage than 14V DC. Unused wires must be insulated with electrical tape so that they do not touch  
other wires or the chassis

SOLENOID CONNECTION  
1
Wire from solenoid:  
Connect to Ignition activated  
Supplied 5A fuse  
Yellow wire from control unit  
(
1) Vent to atmosphere  
Wire from solenoid  
(
nipple on BOV  
2) To pressure  
(
3) To pressure source  
Electrical connection  
Connect one wire of the solenoid to a fused (use supplied fuse) ignition activated 12V power source and connect the other wire to the  
Solenoid trigger signal (Yellow) on the BOV controller unit. Polarity is not important.  
Pressure connection  
Port 1: Vent to atmosphere.  
Port 2: To pressure nipple of BOV.  
Port 3: To pressure source e.g. Intercooler piping (Make sure the pressure source is not shared and that it is from the same part of the  
pipe work as the BOV)  
THROTTLE POSITION CONNECTION  
The BOV controller can be wired to the existing throttle position sensor on your vehicle. Connect the white wire to the signal output wire  
from the existing throttle position sensor.  
(OPTIONAL) For vehicles without a standard throttle position sensor (such as the 12V Cummins Diesel engine), an external one can be  
wired in. The ORANGE AND GREEN must be used to power the external throttle position sensor if one needs to be installed as the  
TPS requires a 5V power supply and not a 12V power supply.  
SWITCHED INPUT CONNECTION (OPTIONAL)  
If your vehicle does not have a standard throttle position sensor and you do not want to install an external throttle position sensor, a  
double throw switch can be used to activate the BOV. The switch needs to ground the GREY WIRE ONLY when the accelerator pedal  
is pressed in and needs to ground the BROWN WIRE ONLY when the accelerator pedal is released.  
ADJUSTING YOUR BOV CONTROLLER  
DURATION: The duration is the length of time that the solenoid blocks the pressure signal to the BOV. The longer the duration, the  
longer the BOV will not have pressure supplied to the cap, essentially keeping the BOV open. The controller also has an override  
function which reactivates the BOV once it detects positive throttle movement, independent of what the duration is set at.  
SENSITIVITY: The sensitivity setting determines how the BOV controller reacts to throttle movement. The controller will only activate on  
negative changes in throttle. The higher the sensitivity setting, the lower the negative change in throttle movement needs to be before  
the solenoid will activate the BOV e.g. a change from 4V to 3.5V will not activate the valve but from 4V to 3V will activate the valve.  
(OPTIONAL IF SWITCHED INPUT CONNECTION METHOD IS NOT USED) ENABLE FUNCTION: Grounding the BROWN WIRE  
activates the enable function which allows the BOV controller to keep the solenoid activated. Even though the unit is still reading  
changes in throttle position, it will not respond to them, not allowing pressure to reach the top of the BOV. The yellow LED will stay on  
when this function is activated. This function can be used to limit boost as the BOV will not have any pressure keeping it closed. It can  
also be used as an over boost safety feature when connected to another device such as a data logger or ECU which can ground the  
wire if a over boost scenario is reached.  
(OPTIONAL IF SWITCHED INPUT CONNECTION METHOD IS NOT USED) DISABLE FUNCTION: Grounding the GREY WIRE will  
activate the disable function which disables the BOV controller. The BOV controller is still switched on but will not respond to changes in  
throttle position, keeping pressure to the top of the BOV, not allowing the BOV open. This can be used when the BOV is not required to  
be functional e.g. when using cruise control, the BOV will not actuate on sudden throttle changes cresting hills.
