Product Overview
The AEM Digital Wideband UEGO AFR Gauge 30-4110 is a standalone air/fuel ratio controller and display that provides real-time monitoring of engine air/fuel mix. It features a dual-LED display system—center and outer rings—that show AFR and Lambda values across a range of fuel types, with precise readings from 10:1 to 18:1 for gasoline and tailored ranges for E85, ethanol, and methanol. The gauge operates independently, requiring no additional sensors or tuning software, and delivers accurate data directly to the driver or tuning system via a 0-5V analog output.
Key Features
- Precise air/fuel ratio monitoring with digital LED readouts
- Supports multiple fuels including E85, ethanol, and methanol with accurate output ranges
- 0-5V analog output compatible with ECU tuning systems
- Includes interchangeable bezels and faceplates for custom appearance
- No external sensors or tuning software required for operation
