The GFB G-Force III boost controller is designed to not only bring boost on as fast and accurately as possible on a
turbocharged vehicle, but also to provide you with an accurate wideband Air/Fuel Ratio gauge using an externally
connected wideband module. The G-Force III 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 III also features a revised interface, making menu navigation and setup as fast and simple as ever.
Features at a glance:
ŸMultifunction boost and AFR (Air/Fuel Ratio) gauge with simple menu button toggle
ŸLean AFR warning can be set to cut boost pressure if engine runs too lean under load
Ÿ6 individually programmable boost preset memories, selectable on-the-fly
ŸClosed-loop correction - helps prevent boost variations
ŸUnique scramble boost strategy - increase or decrease boost for a certain amount of time at the push of a button
ŸOverboost protection - shuts down the solenoid and flashes a warning if boost goes too high
ŸExternal input - can be used to activate scramble or select boost presets remotely
ŸAdjustable button illumination colours - match your car’s existing lighting
ŸAFR gauge can display Lambda or AFR, and can be configured for different fuel types
ŸBoost/vacuum gauge display - in BAR, kPa, or PSI
ŸPeak hold boost pressure display
Installing the Head Unit
The G-Force III 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 III
can be mounted on a vertical face of the dashboard, or
stood up on its edge using the supplied double-sided
mounting tape.
