xOverview
The Gledewen 30-0300 Wideband UEGO Air-Fuel Ratio Gauge reveals real-time fuel mixture shifts as you drive, helping you approach tuning with clarity. The compact 52mm gauge fits standard dashboards and works with wideband control systems using the LSU 4.9 sensor for quick, reliable feedback. Expect a crisp, high-contrast display and a setup designed for flexible monitoring of AFR, Lambda, or O2% views.
Real-time insights that support informed tuning
Real-time feedback from the gauge helps you observe how small changes in load, RPM, or boost affect the air-fuel balance. While results depend on many variables, having continuous data can support safer experimentation and more precise adjustments based on actual conditions.
- 20 ms typical response delivers near-instant indication of changes during driving or tuning
- 0-5V analog output plus RS-232 serial output enables flexible data logging and integration
- Auto-dimming feature reduces glare for easier viewing in low-light conditions
- Configurable display modes (AFR, Lambda, or O2%) and 3- or 4-digit precision for quick interpretation
- Calibration options include Free Air (ACAL) or Resistor Trim (rCAL) for reliable setup
- Wideband LSU 4.9 sensor provides compatibility with common AFR control strategies
- Designed for 12V operation with straightforward wiring for steady, dependable readings
In real-world use, users often pair the gauge with their tuning workflow to observe how changes correlate with engine response across gear shifts and RPM bands. The kit includes the essential components to get started, making it practical for both initial setup and ongoing monitoring.
