MultiGauge App Details

This 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-AFR - Wideband Air/Fuel Ratio Sensor Module SM-Vac/Boost - Vacuum/Boost Sensor Module Compatible Hardware Combinations: SM-AFR + MultiGauge Link. SM-Vac/Boost + MultiGauge Link. SM-AFR + SM-Vac/Boost + MultiGauge Link. 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.

  • When will we have more sensor displays???

    By jhenrayb
    Works great as a wideband. Needs fluids/temps
  • Inconsistent connection

    By RedHotSS
    Sometime it will connect instantly. Other times, it won’t connect at all. I’m a bit disappointed with this app thus far.
  • Needs iPhone X & Apple Watch Support!

    By Libertyforall
    Needs iPhone X & Apple Watch Support! Also, PLX allows no other third party like Track Addict to access this MultiGauge Link, making it a one trick pony! Do yourself a favor and do t but it until they open it up with an SDK! Is this app dead?! No updated in a YEAR!
  • It does not connect!

    By AmhFtK
    Unfortunately I were not able to establish connection between devices. Please fix
  • SM-AFR

    By Rich-
    I am using this to view my SM-AFR wideband and it works fine BUT you have to close the app before you restart the car or try to view the display again because it will freeze. I don’t know if maybe this is limited to the iPhone X or not.
  • Great app, great hardware

    By Janche1010
    I've used PLX widebands for years. This is a great update from my DM6 gauge where I don't need to permanently mount my hardware. With the MultiGauge link I just launch the app and it connected right away. All of my sensor modules are detected automatically and I've got all my data right here on my iPhone. I'm looking forward to this app supporting more sensor modules. Works great, connected without having to pair my Bluetooth and data comes in quick. Nice!!!
  • Garbage. Probably an alpha test.

    By xander_134
    This app doesn't pair with PLX's Kiwi 3, and crashes frequently. From their website, this app looks like it's going to be a component of a "6 in 1" app ($40 USD) they're looking to release this summer but have not yet. For now this app seems inoperative and I wouldn't bother downloading it.
  • The rotation doesn't work

    By VNS - MAC
    I try use in 90 degree format, and the app loose all configurations, please work on this issue! Tks
