Description

AEM Digital Wideband UEGO AFR Gauge (No Sensor) | 30-4110NS

Monitor real-time Air/Fuel Ratios with the AEM Digital Wideband UEGO Controller Gauge (PN: 30-4110NS). Sold without a sensor for easy replacement or custom sourcing.

The AEM Digital Wideband Universal Exhaust Gas Oxygen (UEGO) Air/Fuel Ratio Gauge (Part Number: 30-4110NS) delivers industry-standard accuracy, speed, and real-time fuel mixture tracking without requiring you to purchase an unnecessary sensor. This standalone controller gauge option is designed for tuners and enthusiasts who already possess an approved Bosch LSU 4.9 sensor, need a replacement gauge unit, or prefer to source their wideband sensor independently.

Built around a standard 52mm (2-1/16”) gauge housing, the unit features a high-visibility center digital LED display paired with a sweeping multi-color LED "needle". The dynamic LED display changes color as your air/fuel mixture shifts from rich to lean, granting immediate visual feedback during dyno sessions or high-boost pulls. With integrated 0-5V analog and RS232 serial outputs, the AEM 30-4110NS seamlessly connects with standalone ECUs, piggyback systems, and data loggers—providing fast 0.1 AFR accuracy without ever requiring free-air calibration.

Each kit comes customizable out of the box with interchangeable black and white faceplates, a dedicated Lambda faceplate, and interchangeable black and silver bezels to seamlessly match your vehicle interior or dashboard layout.

Best Uses

  1. Standalone Gauge Replacement: Ideal for replacing a damaged or failed AEM wideband gauge unit while keeping your existing Bosch 4.9 LSU sensor and wiring harness in place.
  2. Cost-Effective Tuning Builds: Perfect for builders who already own a compatible Bosch 4.9 LSU wideband sensor or prefer buying sensors in bulk/separately.
  3. Engine Management & Data Logging: Connecting to standalone ECUs (like AEM Performance Electronics, Megasquirt, Haltech, or Link) using the 0-5V analog or RS232 serial outputs for closed-loop fuel feedback tuning.
  4. High-Performance EFI & Carbureted Tuning: Monitoring precise Air/Fuel ratios on forced induction (turbocharged/supercharged) or high-compression naturally aspirated engines to prevent catastrophic lean conditions.

Features

  1. No-Sensor Option (PN 30-4110NS): Includes the controller gauge and installation hardware without the wideband sensor, avoiding redundant costs.
  2. Zero Free-Air Calibration Required: Factory-calibrated controller firmware eliminates the hassle of performing free-air sensor recalibrations when paired with approved Bosch LSU 4.9 sensors.
  3. Dual Data Output Streams: Equipped with both 0-5V analog output and RS232 serial output for seamless integration with data loggers and engine control units.
  4. Customizable Faceplates & Bezels: Ships with interchangeable black and white faceplates (AFR and Lambda options) along with black and silver bezels for a tailored dashboard aesthetic.
  5. Dual Digital & LED Sweeping Display: Features a 3-digit center display reading to 0.1 AFR precision accompanied by a 24-color-coded outer LED ring for quick visual reference.

Benefits

  1. Engine Protection: Provides immediate, sub-tenth (0.1 AFR) precision tracking to alert you to lean conditions before severe engine knock or piston damage occurs.
  2. Universal 52mm Fitment: Fits standard 2-1/16” gauge pods, pillar mounts, and custom dashboard cutouts for quick, painless installation.
  3. Versatile Fuel Compatibility: Accurate readings across multiple fuel types—including Gasoline, E85, Ethanol, Methanol, or direct Lambda measurements.
  4. At-a-Glance Monitoring: The dynamic multi-color LED ring allows drivers to monitor rich/lean states instantly without losing focus on the track or road.
  5. Budget Flexibility: Saves money up front if you already have spare sensors or plan to source replacement sensors individually.
