GFB G-Force III Electronic Boost Controller with AFR Monitoring (MPN 3005)

The GFB G-Force III Electronic Boost Controller (MPN 3005) provides precision boost management and advanced engine protection in a single compact unit. This third-generation controller allows you to monitor and display your engine's air/fuel ratio (AFR) or Lambda by connecting the analogue output of most wideband O2 controllers to its auxiliary input. This eliminates the need for a separate AFR gauge while providing a critical safety layer for high-performance forced induction systems.

Built with engine longevity in mind, the G-Force III features a lean-mixture safeguard that automatically drops boost to the minimum setting and flashes the display if a lean condition is detected. Users can configure up to six distinct boost presets for different driving scenarios and activate a dedicated scramble feature for temporary peak performance or engine protection.

• Integrated AFR Monitoring: Displays Air/Fuel Ratio or Lambda when connected to an external wideband controller (sold separately).
• Advanced Safety: Visual warnings and automatic boost reduction to the lowest setting if the engine runs lean under load.
• Six Boost Presets: Quickly toggle between six user-defined boost levels on the fly for street or track use.
• Scramble Feature: Remotely trigger a boost offset for overtaking, launching, or towing.
• Customizable Interface: Selectable display colors to match your vehicle's interior dashboard lighting.
• Precise Solenoid Control: Replaces factory boost control for faster spool-up and stable peak boost pressure.
