ES Series 2-1/16 Digital Air/Fuel Ratio-Pro Gauge, 6:1-20:1

Brand: Auto Meter Gauges

Wideband Air-Fuel Ratio Gauges from Auto Meter allow for much greater consistency and accuracy than conventional single-wire air-fuel ratio monitors.

User-programmable range and sensitivity make this kit perfect for tuning as well as long-term monitoring of engines running on gasoline, methanol, ethanol, propane, or CNG. A linear 0-4v output allows you to connect this gauge to your data logger or aftermarket ECU. A dual digital LED readout displays air-fuel ratios or Lambda values directly, as well as by a quick-read 30-LED bar graph around the dial face.

This ES style features a black face with a black bezel. The dash-mount 2 1/16" gauge is easy to fit in a wide variety of applications. Includes Bosch wideband oxygen sensor, weld-in threaded bung for exhaust pipe, wiring harness, and full instructions.
