Tune RevHeadz for a responsive drive.
Follow these screens to connect REVKING and match the sound response to your vehicle.
APP STEP 1
Open the OBD-II connection
From the RevHeadz drive screen, select the OBD-II control to begin connecting REVKING.
Bluetooth must be enabled on your phone.
APP STEP 2
Set your vehicle's redline
Adjust the RPM value to suit your vehicle so the generated sound follows the engine more naturally.
Use the manufacturer's specified redline for your vehicle.
APP STEP 3
Connect through Bluetooth
Select Connect (Bluetooth), confirm the connection status, and return to the drive screen.
Complete setup while parked before testing the response.
BETTER AUDIO
Make every response feel tighter.
Your connection method affects latency. Choose the setup that best matches your vehicle and audio system.
WIRELESS CONVENIENCE
Bluetooth can add a small delay
Wireless audio has to encode and decode the signal. Depending on the phone and stereo, that can create noticeable lag.
Best for quick, cable-free setup
LOWER LATENCY
Use AUX when your stereo supports it
A direct AUX connection can provide a faster, more stable audio path with less delay than a wireless audio connection.
Best for the tightest available response
Complete setup while safely parked.
Set your connection and response before driving. Never adjust the app while the vehicle is moving.
