MQB Tune Adjuster

Adjust the Boost and Octane on your Mk7/MQB Eurodyne tune without booting Windows!

This works with the commonly available Elm327 Bluetooth dongles used with other Android data logging apps.

To use:

1) Pair your dongle in the Android Bluetooth settings. The passcode is usually 1234.
2) Turn the ignition on in your vehicle.
3) Start the app
4) Slide the Connect slider to the right
5) Pick your OBDII device, usually called OBDII
6) Wait 10-20 seconds.

At this point you should see your settings.

You can adjust the sliders and hit Save to adjust the settings. Slide the slider to the left to disconnect and relinquish the Bluetooth device if you want to use it with another app later.

Press Back to fully exit the app and stop the Foreground Service.
