GFB G-FORCE III Electronic Boost Controller

GFB G-FORCE III Electronic Boost Controller

Regular price $387.00

Unit price per 

The latest iteration of GFB’s feature-packed electronic boost controller now has the ability to monitor and display your engine’s air/fuel ratio in either Lambda or AFR. By connecting the analogue output of most wideband O2 controllers (i.e. Innovate LC-2, AEM UEGO etc, sold separately) to the G-Force III’s auxiliary input, you can toggle between boost pressure and air/fuel ratio display. Not only does this save you from having to install a separate AFR gauge in your car, it can also save your engine!

A lean mixture at high boost can destroy an engine in seconds, and a stand-alone AFR gauge is next to useless when accelerating hard as your concentration is likely to be (and should be!) on the road in front of you. The G-Force III safeguards your engine against a lean mixture by lowering boost to the minimum setting, and visibly warning you by flashing the display lighting.

  • Separately adjustable overboost and lean mixture waring/boost cut

  • Auxiliary input to switch boost presets or activate scramble
  • ½ Din size casing, fits standard stereo slot
  • Supplied with mac 3-port solenoid
