MultiGauge App is designed to function with the PLX Devices Multi Gauge Link hardware interface. The Multi Gauge Link includes a Bluetooth LE wireless communication protocol designed to work seamlessly with this app. PLX Devices sensor modules can be connected in a daisy-chain and the Multi Gauge Link is connected to the last sensor module in the chain to transmit sensor data to your smart phone for visual display. Compatible Hardware: Multi Gauge Link SM-PRO - Fluid Temp, Exhaust Gas Temp, Air Intake Temp, Fluid Pressure, Vac/Boost SM-AFR - Wideband Air/Fuel Ratio Sensor Module Compatible Hardware Combinations: SM-AFR + MultiGauge Link. SM-Vac/Boost + MultiGauge Link. SM-AFR + SM-Vac/Boost + MultiGauge Link. SM-PRO + SM-AFR + MultiGauge Link SM-PRO + MultiGauge Link SM-Pro is a combined sensor module for accurately measuring Vac/Boost, Exhaust Gas Temperature, Air Intake Temperature, Fluid (Oil/Water) Temperature, and Fluid Pressure. Includes genuine Honeywell 3Bar Vac/Boost sensor (built-in), wires/connectors for digital interface with DM-6, DM-100/200, MultiGauge Link. Also includes analog outputs for interfacing with 3rd party ECU's and data loggers. The SM-AFR Gen4 Sensor Module is a tuner grade Bosch LSU 4.9 wideband oxygen sensor controller with digital/analog outputs for 3rd interface. Accurately reads the air/fuel ratio of any internal combustion from 0.68 Lambda to 1.36 Lambda (10:1 - 20:1 AFR *Gasoline). Fully plug and play, no sensor calibration is required. Compatible with Gasoline, Diesel, Ethanol, Methanol, E85, LPG, CNG. Accurate to 0.1AFR with less than 100mS reaction time from rail to rail. Advanced sensor health monitoring, displays oxygen sensor health and reaction time when connected to DM-6 gauge or to your smartphone via the Multi Gauge Link interface. The SM-Vac/Boost Sensor Module accurately measures the vacuum pressure and boost pressure of any intake manifold. This is ideal for turbo and supercharged applications where monitoring the intake pressure is vital. The Vacuum / Boost Sensor Module can also be used as a stand alone unit capable of interfacing with 3rd party hardware where both the digital output and the analog output are available simultaneously. Its measurement range is 30.5 inHg to 30 PSI or 760 mmHg to 2.11 Kg/cm^2. Connect this sensor module via the Multi Gauge Link interface for a boost gauge on your smartphone.
