Speedhut 2-5/8" .6-1.2 Lambda Air/Fuel Gauge w/ Warning (R25-WB2-REV)

The Speedhut 2-5/8" .6-1.2 Lambda Air/Fuel Gauge w/ Warning (R25-WB2-REV) offers precise monitoring of your engine's air/fuel ratio. This standalone wideband gauge features a built-in controller, eliminating the need for external components. Its clear 2 5/8 inch (68mm) display provides readings in lambda within a range of 0.6 to 1.2. Equipped with a warning light, this gauge allows you to quickly identify potentially harmful lean or rich conditions, helping to protect your engine and optimize performance. The gauge is designed for a standard 2.67" (68mm) mounting hole, ensuring straightforward installation.

KEY FEATURES AND BENEFITS:

Precise Air/Fuel Monitoring: Provides accurate lambda readings between 0.6 and 1.2, crucial for engine tuning and diagnostics.

Standalone Operation: Features an integrated wideband controller, simplifying installation and reducing the need for additional hardware.

Early Warning System: Includes a built-in warning light to alert you to out-of-range air/fuel ratios, preventing potential engine damage.

Standard Sizing: The 2 5/8 inch (68mm) gauge size fits common mounting locations.

Complete Kit: Ships with the necessary LSU 4.9 wideband O2 sensor and a 3 ft power & lighting harness, ensuring you have everything needed for installation.

LSU 4.9 Wideband O2 Sensor

3 ft Power & Lighting Harness

Mount the Gauge: Locate a suitable 2.67" (68mm) diameter hole in your desired location and securely mount the Speedhut gauge.

Install the O2 Sensor: Install the included LSU 4.9 wideband O2 sensor into the exhaust system at a location recommended for accurate readings (typically before the catalytic converter and after the exhaust manifolds converge).

Connect the Wiring Harness: Connect the provided 3 ft power & lighting harness to the gauge and to a suitable power source and ground in your vehicle's electrical system. Refer to the wiring diagram included with the product for specific connections.

Connect the O2 Sensor: Connect the LSU 4.9 O2 sensor to the designated connector on the gauge or wiring harness.

Start Your Vehicle: Once all connections are secure, start your vehicle. The gauge should power on and begin displaying the real-time lambda value.

Observe Readings: Monitor the air/fuel ratio readings to ensure your engine is operating within the optimal range.

Heed the Warning Light: If the warning light illuminates, it indicates that the air/fuel ratio has fallen outside the preset safe limits. Investigate the cause promptly.
