Description

AEM Digital Wideband UEGO Air/Fuel Ratio Gauge (PN 30-4110) | Precision Tuning

Monitor engine performance with the AEM Digital Wideband UEGO Gauge (PN 30-4110). Fast response, Bosch 4.9 LSU sensor, 0–5V output, and zero free-air calibration needed.

The AEM Digital Wideband UEGO (Universal Exhaust Gas Oxygen) Air/Fuel Ratio Controller Gauge is an essential tuning instrument for high-performance and modified vehicles. Engineered to detect air/fuel ratio changes as small as 0.1 AFR, it gives tuners and drivers real-time data to optimize horsepower, improve fuel efficiency, and prevent severe engine damage caused by overly lean conditions.

Featuring a bright center digital LED screen surrounded by a multi-color sweeping LED "needle," the gauge provides immediate visual feedback at a glance. The kit includes the industry-standard Bosch 4.9 LSU Wideband Sensor, which delivers speed and accuracy without ever requiring manual free-air sensor calibration. Packaged in a standard 52mm (2-1/16") housing with interchangeable bezels and faceplates (black and white included), this gauge integrates easily into custom dash pods or stand-alone engine management setups.

Best Uses

  1. Dyno & Street Tuning: Real-time feedback for recalibrating carburetors, stand-alone ECUs, and piggyback tuners.
  2. Forced Induction Systems: Essential safety monitoring for turbocharged and supercharged builds to prevent lean-detonation under boost.
  3. High-Performance & Racing Vehicles: Track-day and drag-race vehicles running high loads where precise fuel mixture management is vital.
  4. Engine Diagnostics & Data Logging: Wiring the 0–5V analog output directly to data loggers or ECUs for automated air/fuel logging.

Features

  1. Bosch 4.9 LSU Wideband Sensor: Delivers precise, fast-reacting AFR measurements under demanding thermal conditions.
  2. Zero Free-Air Calibration Required: Factory-calibrated resistor trim ensures accuracy straight out of the box without manual recalibration.
  3. Dual Digital & LED Needle Display: Central digital LED readout combined with a sweeping color-changing LED rim for quick visual assessment.
  4. 0–5V Analog Output: Connects directly with third-party data loggers, engine management systems, and standalone ECUs.
  5. Customizable Appearance: Comes with interchangeable black/white faceplates and black/silver bezels to match any dash cluster design.

Benefits

  1. Prevents Catastrophic Engine Damage: Provides early alerts to lean fuel conditions before detonation or thermal failure occurs.
  2. Maintenance-Free Calibration: Eliminates time-consuming free-air calibration routines during setup and routine maintenance.
  3. Seamless ECU Integration: Feeds clean, high-speed 0–5V output signals straight to your engine tuner or data logger for closed-loop control.
  4. Universal Standard Fitment: Fits standard 52mm (2-1/16") gauge pods for simple installation in virtually any vehicle.
  5. Immediate At-a-Glance Monitoring: The color-coded perimeter LEDs allow drivers to monitor mixture shifts instantly without losing focus on the road or track.
