RevHeadz Engine Sounds

OBD2 connection instructions for iOS

Bluetooth OBD2 adapters for iOS need to be Apple certified and some require app whitelisting by the device manufacturer to work with 3rd party apps.

Disconnect OBD2 adapters from the vehicle when not using your car to avoid drained battery.

Electric Vehicles are not supported by RevHeadz at this time.

Avoid using Bluetooth audio output while using RevHeadz OBD2 as it introduces significant lag in the sound output.

We have tested with the following OBD2 Bluetooth adapters on iOS:

Connection

If everything works you should now see the connection showing some data reported by your car. Specify your vehicle's redline RPM using the scroll buttons. This is so the app can map the RPM range of your vehicle to the RPM range of other vehicles that may have different rev ranges than your car. Optionally you can set this value slightly lower to achieve higher revving engine sounds from lower revs. Leave the Optimize Communication setting to On unless you experience issues. Navigate back to the main menu by clicking the Back button in the top left. On the main menu the OBD2 button light will be green when there is an active connection and entering the Drive mode for any of the engines will use OBD2 data to drive the sound simulation.

Troubleshooting

Make sure no other apps are trying to communicate with the OBD2 adapter while trying to connect with the RevHeadz app as they may prevent it from connecting. Note that some of these apps will maintain an OBD2 connection with your adapter even after closing the app. If you experience issues getting OBD2 to work then click the Diagnostics button after you have tried to connect. The diagnostics screen will contain information that can be saved to a log file on your phone. Click the Copy To Clipboard to save the information so it can be emailed to us.

The OBD2 feature of RevHeadz is still relatively new so there may be bugs or incompatibilities that we're unaware of yet so please be patient while we work on bringing future updates and improvements.

Tips

Some cheap OBD2 adapters don't use a low power mode so should be disconnected from your car's OBD2 port when not in use to avoid draining your car battery.
