ARTILAURA Wideband AFR Gauge Wideband O2 Air/Fuel Ratio Gauge Kit LSU 4.9 Oxygen Sensor AFR Gauge Meter

Real-Time Monitoring: Wideband Air Fuel Ratio Gauge tracks air-fuel ratio changes in real time,delivering data for your engine. When paired with a quick-reacting LSU 4.9 UEGO sensor (20ms typical), it keeps your engine running at peak performance

Feature: 2-1/16" (52mm) Air/Fuel Ratio Gauge with black dial. 8.0:1 to 20.0:1 AFR / 0.55 to 2.00 Lambda. 8.0:1 to 20.0:1 AFR / 0.55 to 2.00 Lambda. Supports up to 16V system voltage and works with the LSU4.9 sensor. With 0–5V analog output, Serial RS-232 Output and CAN bus output, lets you switch between three key display modes—AFR, Lambda, and O2%—for instant, at-a-glance data

Customizable Viewing: Digital wideband AFR gauge customize the display to 3 or 4-digit, switch between AFR, Lambda, and O2% modes, and use the 24-color LED ring to check mixture status at a glance. The bright 4-digit readout works day or night

Dual Calibration Modes: UEGO sensor has two calibration methods: (1) rCAL (Resistor Trim Calibration), the factory-default mode with pre-set trim resistor calibration that needs no extra setup for most applications. (2) ACAL (Free Air Calibration) - just remove the sensor from exhaust, run the 10–15 second ACAL menu function in fresh air, and check the gauge's PASS/FAIL readout
