Description

The ZZPerformance DM-6+SM-AFR is a wideband air/fuel ratio gauge combo designed for accurate engine monitoring. This system utilizes a Bosch LSU 4.9 sensor to measure air/fuel ratios across a wide range. It is compatible with various fuel types, including gasoline, bio-diesel, ethanol, methanol, E85, LPG, and CNG, with a measurement range of 10.0:1 to 20.0:1 AFR for gasoline. The unit provides both a wideband 0-5V analog output and a digital output for integration with other monitoring systems or data loggers. The SM-AFR controller is designed to connect with PLX Multi Gauges, allowing for daisy-chaining of up to 16 sensor modules. Battery voltage is displayed from 9V-20V, and sensor life is indicated from 0-100%. Please note that the O2 bung and cap are sold separately.
