GFB G-FORCE III Electronic Boost Controller

GFB's flagship electronic boost controller. The G-Force III can monitor and display your engine's air/fuel ratio (in Lambda or AFR) by reading the analogue output of most wideband O2 controllers through its auxiliary input, so it can lower boost and flash a warning if it sees a lean mixture. Set up to 6 boost presets and switch on the fly, use the scramble feature for overtaking, launching or towing, and customise the display lighting colour to suit your interior.
