RealDash App Setup

Install the RealDash app on your Android device. We recommend the upgraded version, but it may not be required.
• Swipe up to reveal the menu, and select “Garage”. You’ll see the animated car enter, click on the door, and then click on the dashboard. You’ll get a “Connections” menu. If this is your first time starting RealDash, it may take you to the Connections menu when the app is getting setup.
• Choose “Adapters (CAN/LIN)”, then select “ReaDash Can”. Select “Bluetooth” connection, and the connect to your Bluetooth device, either “ONEGAUGE” or “HC-05” (for help with this step, see the Torque App instructions above).
• You’ll then need to download the RealDash CAN Description File to your phone. It is available on our website at
• You’ll need to use the “Custom Channel Description” option and use the OneGauge Realdash XML file you downloaded from the FAQs portion of the website. Once you select the description file, hit done and navigate back to the main gauge screen.
• You can then add gauges by swiping up on any screen and touching “edit”. RealDash provides various “data sources” for gauges, but all of the readings from OneGauge will appear in the “ECU Specific”
category. Please note, if you select the default sensor readings you will not get correct data. You must select the sensor readings in the “ECU Specific” category that are labeled “OG”.
o For example, the default RPM reading will be found under Engine/ECU Inputs. However, OneGauge does not transmit data to this gauge. You will need to reassign your Tachometer gauge that you create, or the default gauge, to the “OG – RPM” sensor in the ECU Specific category.
• Buttons can also be found in the ECU Specific category, which are used to trigger relays if purchased. They are named “Button 1”, “Button 2”, etc., and they correspond to relay 1, relay 2, etc. installed with your OneGauge hub.

• For information on making RealDash automatically start up when it connects to OneGauge, see the Tasker instructions in the Torque App Setup instructions above.
• There are variety of default settings in RealDash that may need to be removed for the app to function properly and give correct readings on some sensors. In the main menu, click ‘Settings’, scroll to ‘Units and Values’, and use the arrow in the bottom right corner to go to page 2.
o These input maps may change the way that RealDash reads sensors. We recommend deleting any Fuel Pressure, Oil Pressure, and other sensor readings in this list that you are using for your setup. You can also use this menu to set up indicator lights based on inputs from OneGauge.
