About this app

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.

Ratings and reviews

Very unstable app, switching from this App to another and back will always result in a unresponsive App. Frequently have to disable/enable Bluetooth to connect to it, have this issue on four phones so seems to be App related. Would be nice if the App would support a vertical viewing as well. Considering the cost of the solution and absolute lack of any updates for years, a disgrace.

it is totally inappropriate to ask your clients buy a product (bluetooth adaptor) that still is not usable after 2 years of development. App blocks easily and in most cases is imposible to reconnect. the easiest way is to restart your phone. Not ideal when you drive. Also the interface has a default setup showing all sensors.When you change it by closing values that you don't use, there is no option to keep this setup somehow. So next day when you open again the app you see the same default interface showing all sensors.... you must be idiot not amending this thing after so many years of development. Update 2020/09/22: i complained about all the above in facebook page and they blocked me. Not only they have not corrected anything all these years, but also trying to hide issues.

Connected once...blutooth device shows its connected to phone...after that the app crashes every time I try to load and it connects and kills the app instantly...tried it on several android phones and tablets around the house....as far as using it to connector my data logger that works just fine....but the BT connection .....waste if time money and effort to date...you guys have no apparent reason for this not to work on so many types of device...Will try it on my old iPhone and see how goes
