PLX Gen 4 Wideband AFR Combo Kit | DM-6 Touchscreen Gauge & SM-AFR Module
Take total control of your engine tuning with the next generation of air/fuel ratio monitoring. The PLX Gen 4 Wideband AFR Combo pairs the redesigned, ultra-efficient SM-AFR controller with the patented DM-6 touchscreen MultiGauge.
Featuring active Intelligent Health Monitoring and advanced power management, this plug-and-play system samples sensor data every 2 milliseconds (488 times per second) to deliver laboratory-grade accuracy, blazing fast response times, and maximum sensor longevity.
Key Features & Advancements
- Intelligent Sensor Health: The brilliant, high-contrast OLED DM-6 display live-tracks your real-time battery voltage (9V-20V), current sensor life (0-100%), and oxygen sensor reaction time (10ms-1000ms).
- Genuine Bosch LSU 4.9 Technology: Includes the industry-standard LSU 4.9 wideband sensor. No manual free-air calibration required.
- Genuine Bosch LSU 4.9 Technology: Includes the industry- standard LSU 4.9 wideband sensor. No manual free-air calibration required.
- Simultaneous Triple-Output Routing: Equipped with three distinct outputs that can all be utilized at the same time:
- Wideband Analog (0-5V): Ideal for seamless integration with aftermarket ECUs, piggybacks, and data loggers.
- Narrowband Analog (0-1V): Simulates a factory narrowband sensor, allowing you to feed the signal directly back to your stock ECU.
- Digital Serial Output: Connects flawlessly to the DM-6 gauge or other daisy-chained multi-gauges.
- Multi-Fuel Dynamic Tracking: Fully compatible with Gasoline, Diesel, E85, Ethanol, Methanol, Biodiesel, LPG, and CNG. Accurate down to 0.1 AFR resolution (on gasoline).
- Advanced Soft Start Technology: Safely and gradually warms up the oxygen sensor upon startup, dramatically extending its service life and preventing thermal shock.
- Rugged Enclosure: Housed in a premium, durable aluminum chassis built to handle demanding vehicle environments.
