Description Technical Specs
Wideband AFR modernized.
The new PLX Wideband AFR Smartphone combo takes engine efficiency to the next level. Our Wideband SM-AFR controller coupled with the new MultiGauge Link™ allows you to wirelessly send data to any smart device eliminating the need to install dedicated gauges in your vehicle. Simply launch the MultiGauge™ app, available now for Apple and Android, to instantly connect to your smart device for brilliant real-time gauges.

MultiGauge™ app for Apple and Android

The app automatically detects your PLX sensor modules and configures your gauges. MultiGauge reports both 0-15 PSI and 0-30 PSI boost ranges in both imperial / standard and metric units.The AFR sensor module supports lambda as well as all fuel types–gasoline, diesel, methanol, ethanol, E85, CNG, and LPG.

With both AFR and and Vac/Boost modules attached, MultiGauge automatically configures to display both parameters. This combination allows for advanced features like intelligent warning which alert you if your engine is running in unsafe conditions.

Already have sensor modules?
The MultiGauge Link™ is all you need to connect your existing sensor modules to your smart device for a new and updated user experience. If you already have our SM-AFR + DM-6 gauge combo, simply connect our y-splitter and you can run DM-6 and MultiGauge™ app simultaneously.

Popular Configurations

PLX Wideband now 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.
