    • Vehicle roll/tilt or g-force measurements
    • Various data logging options
    • Tire pressure and temperature monitoring systems
    • Proximity sensors available for parking, collision detection, object avoidance, etc.
  • Lap timing and race features like 1/4 and 1/8 mile times, custom or pre-set track lap times, fuel mileage calculations, etc.
  • If you can dream it, we can probably build it! Reach out to with questions or requests!


The OneGauge Hub is the “brain” of the OneGauge setup- it receives all of the sensor data and sends it to your selected screen. OneGauge is based on the popular Arduino platform, which makes it easy and very inexpensive to replace components in the future. Screw terminals are provided so that sensors can easily be added by the user.

A standard hub supports 3 analog temp sensors, 2 fuel level sensors, 1 analog pressure sensor, 5 digital pressure sensors (including vacuum/boost), 2 oxygen sensors, 3 voltage inputs, 2 RPM/tach or VSS speed inputs, 4 digital temperature inputs, 8 high temperature sensors, and various other optional features like a GPS speedometer, accelerometer for vehicle roll/tile or g-force readings, SD card data logging, a permanent storage device for Odometer/trip/hour readings, CAN-BUS communication with various devices like TPMS systems, 2 LCD screen outputs, and more. All of these can be custom configured when order to suit your needs.


OneGauge data displayed on Torque app

All OneGauge setups include the ability to connect to an Android phone, tablet, or android head unit to display sensor readings on either Torque Pro or RealDash. These apps allow you to completely customize your dash design and layout, integrate maps or dash-cams, datalog, and much more!

OneGauge can be made to work with Apple devices, but due to slower communication with Apple products you may see delays with fast-changing sensors like RPM and speed. We recommend OBD Fusion or Engine Link apps for Apple devices, which allow adding additional custom sensors for OneGauge input.

LCD touchscreens are the most versatile and customizable display option we offer. These screens have a more professional and permanent appearance and are ideal for instrument clusters or center consoles. LCD touchscreens offer options such as on-screen buttons to control vehicle accessories via relays or LED lighting options for your screen bezels so you can add lights for turn signals, gauges, or warning lights.

If you have some graphic design skills, you can design your own gauges and gauge layout to fit your vehicle. If not, don’t worry- you can adjust one of our pre-made screen designs or we have designers available who could help you design your ideal screen. To see some of our pre-made screen designs, visit our Themes page.

PiDash screens, available at PiDashs.comallow you to use any HDMI-based screen for your OneGauge system! This also opens up options for on-screen customization of your gauge design, wider screens of different sizes and shapes, backup cameras, audio/radio control, and much more. Visit the PiDash website to browse their options and screen sizes available with their kits.


OneGauge offers 3 primary ways to get data – standard sensors wired directly to the hub, a connection to your OBD-II port, if available, or a CAN BUS connection to your aftermarket ECU or EFI system. These systems can all be mixed/matched to add additional readings to any system.


OneGauge supports a ton of standard temperature, pressure, fuel level, AFR/oxygen, speed/RPM, voltage, and other sensors so you can get any reading you need on your dash!


Can Bus provides a 2 wire, plug and play connection that will get you readings directly from your ECU or EFI kit!


OneGauge also offers a ton of additional add-ons and features!

  • GPS Speedometer requires no connection to your vehicle. It can provide speed, altitude, compass, and time information. For racing applications, you can upgrade to our race-spec GPS that updates 15 times per second!
  • Odometer option provides odometer reading as well as optional trip and hour meters.
  • Accelerometer feature gives vehicle roll/tilt readings as well as g-force readings.
  • On-screen buttons and relays to control electronics like lights, fans, fuel pumps etc. These can be triggered manually or automatically by sensor readings.
  • RPM and VSS speedometer inputs that are adjustable and configurable to the output of your vehicle.
  • Fuel level inputs that are fully adjustable to match your tank sender resistance.
  • Data logging through the Torque Pro or RealDash apps, or by a using an SD card reader/writer attached to the OneGauge hub.
  • Lap and distance timing for lap, 1/4 mile, 1/8 mile, and 0-60 times using the GPS option.
  • Fuel consumption tracking to estimate vehicle fuel efficiency.
  • Gear calculations to provide highly accurate current gear for any transmission (without a connection to the transmission!)
  • Tire pressure and temperature setups for up to 10 wheels (more available upon request)
  • Configurable turn signal and indicator inputs to show basic on-screen indicators like headlight, fans, check engine light, and other indicators.

If you need a feature that isn’t listed, please ask and we can make it happen!
