GFB - G-FORCE III Electronic Boost Controller

GFB G-Force III Electronic Boost Controller with AFR Display Capability

The latest generation of GFB’s acclaimed electronic boost controller — the G-Force III — takes boost management to the next level by integrating engine air/fuel ratio (AFR) monitoring directly into your boost controller’s display. Designed for tuners and performance enthusiasts alike, the G-Force III offers unmatched control, safety, and convenience in a compact 1/2 DIN package that fits standard stereo slots.

By connecting the analog output from most wideband O2 controllers (such as Innovate LC-2 or AEM UEGO, sold separately) to the G-Force III’s auxiliary input, you can effortlessly toggle between monitoring boost pressure and AFR or Lambda readings — eliminating the need for a separate AFR gauge cluttering your dash.

This advanced integration is more than convenience — it’s protection. Lean mixtures at high boost levels can destroy engines in seconds. The G-Force III safeguards your engine by automatically reducing boost to a preset minimum if dangerous AFR thresholds are reached and alerts you with a flashing display, allowing you to stay focused on driving without distraction.
