about the g force ii
The GFB G-Force II boost controller is designed to bring on boost as fast and accurately as possible on a turbocharged vehicle. It incorporates an advanced and unique boost control strategy that allows the user fine control over the peak boost, rise rate, and closed-loop correction.
The G-Force II also features a new user interface, making menu navigation and setup as fast and simple as possible.
Features at a glance:
?6 individually programmable boost preset memories, selectable on-the-fly ?Closed-loop correction - helps prevent boost variations
?New scramble boost strategy - increase or decrease boost for a certain amount of time at the push of a button ?Overboost protection - shuts down the solenoid and flashes a warning if boost goes too high
?Peak hold display
?Real-time boost/vacuum gauge display - in BAR, kPa, or PSI
?External input - can be used to activate scramble or select boost memories remotely ?Adjustable button colours - tie in with the car’s existing lighting
91.5mm
Installing the Head Unit
The G-Force II casing is a ½ DIN size, allowing to be mounted into one half of a standard stereo slot.
Alternatively, with its thin profile (18.5mm), the G-Force II can be mounted on a vertical face of the dashboard, or stood up on its edge using the supplied double-sided mounting tape.

Optional Remote Trigger Circuit
Remote trigger button (not supplied). Use any switch, button or sensor that grounds the blue wire when activated
The external input can be used as a remote trigger simply by connecting it to any kind of switch, button, or programmable ECU output that grounds the blue wire to the vehicle earth when activated. For ideas on different ways to use the external input, see page 14. Once connected, the purpose of the external input must be configured within the “INPUT” sub-menu within the menu (see page 12).
The yellow wire currently has no purpose, it is intended for use with future features.
If either the blue or yellow wire are not used, simply cut or bundle them and make sure they are insulated.
WARNING! Do NOT connect the blue or yellow wire to a 12V source as this could damage the unit.

solenoid valve installation
Mount the solenoid valve in a position away from significant heat sources (such as the exhaust manifold and turbine), and where it is protected from rain or splashed water. The unused outlet of the solenoid valve should be positioned facing downwards to avoid ingress of dust, dirt and water.
DO NOT plug the un-used solenoid port, as this will prevent the controller from being able to adjust boost pressure.
Internal Wastegate
Screw the two supplied hose tails into ports 2 and 3 of the solenoid valve, and connect the ports to the correct locations as shown using the supplied 3/16” hose.

Controls peak boost pressure.
Duty Cycle is adjustable from 0-100%, where 0 results in the lowest boost pressure, and 100 is the highest.
Controls how fast the turbo spools up.
Gain is adjustable from 0-100, where 0 is the slowest spool-up, and 100 is the fastest.
Controls how strongly the G-Force II resists changes in boost pressure. Sensitivity is adjustable from 0-100, where 0 results in no correction and, and 100 is the
Sets the number of seconds that the scramble boost feature remains on when activated.
Adjustable from 0-100 seconds.
Turns off the solenoid in the case of over boost.
The Overboost setting is adjustable from 0-345kPa, 0- 3.45bar, or 0-50psi, depending on which display units are currently in use.
Turns the Peak Hold display function on and off.
When set to “ON”, the display shows the peak boost value for 3 seconds after the manifold drops to vacuum.
Changes the display pressure units.
Can be set to kPa (default setting), BAR, or PSI.
Changes the function of the external input wire. “OFF” turns off the remote input, “PrE” jumps to the
next boost preset, and “SCr” activates scramble feature.
Allows changes to the button colours.
The display does not change, but pressing “up” will alter the “scramble/preset active” button colour, and pressing down” will alter the normal “background” button colour.
