## Overview

The PLX C6AFRG4 Wideband AFR and DM6 Gauge Kit combines Bosch's latest LSU4.9 sensor technology with an advanced OLED touchscreen gauge, delivering ultra-fast, precise air/fuel ratio readings. Featuring intelligent health monitoring at 488 checks per second, low 7.5W power consumption, and versatile outputs for seamless ECU and data logger integration, this compact, durable kit is engineered for professional-grade engine tuning and long sensor life.

## Description

We're proud to introduce our next generation wideband oxygen sensor controller with intelligent health monitoring technology and current for improved sensor performance. Our new Gen4 Wideband AFR Gauge Combo utilizes the next generation in Bosch Wideband Air/Fuel Ratio sensor technology. The Gen4 is faster, more accurate, more durable, and uses less power than the Gen3. The Gen4 also employs the innovative PLX Devices new intelligent health monitoring technology where the oxygen sensor is meticulously monitored every 2mS (488 times per second) to obtain peak performance, accuracy and reaction time. Coupled with the updated patented DM-6 touch screen MultiGauge, battery voltage is displayed from 9V-20V, sensor life is displayed from 0-100%. The oxygen sensor reaction time is displayed from 10mS/1000mS on the brilliant high contrast OLED display. The PLX Wideband AFR (UEGO) gauge combo combines an accurate, fast response wideband AFR (Air Fuel Ratio) controller with the world's most advanced touch screen 2 1/16" gauge (52mm). It includes a Bosch LSU4.9 wideband oxygen sensor. The wideband controller (SM-AFR) works with gasoline, bio diesel, ethanol, methanol, E85, LPG, and CNG. It includes two analog outputs (wideband 0-5V, and narrowband 0-1V) for interfacing with 3rd party devices and one digital serial output for interfacing with the DM-6 gauge and other Multi Gauges. The wideband analog output is ideal for interfacing with aftermarket ECU's and data loggers. The narrowband output is ideal for stock narrowband oxygen sensor replacement where the simulated narrowband analog output is fed back into your ECU to make it operate as if the stock narrowband oxygen sensor is still installed while running the PLX wideband setup. All three outputs can be used simultaneously. Additional features include advanced soft start technology which prolongs the oxygen sensor's life and an aluminum enclosure for durability and reliability.

## Features

- More accurate, Faster response time, Faster warm up time
- Uses only 7.5Watts compared to 10Watts
- Improved sensor durability
