Please enable bluetooth and location services on your phone/device, or you won’t be able to connect
From the app home screen:
When you first open the app this is what you see. Click the “tap to connect” button at the top.
Initially you should see this message. Turn the ignition key on the bike and the ECU should pop into view
It should look a little like this:
If the ECU does not appear after a few seconds try turning the ignition off and back on ♦
Tap on the ECU to connect to it. Sometimes it can take a couple of tries to connect ♦
Once connected, this is the main dashboard where you can see real-time info about your bike. When you click start, and once the engine is running these numbers should be updating.

Note: If you have datalogging enabled and leave your phone connected, when you click “Start” on this screen live data is streamed to your phone as you ride. These logs can later be analysed to understand the bike’s behaviour/performance.
The data logged includes engine data (rpm, TPS, temp etc) as well as speed, gps data. If you are using StayTuned with a wideband O2 sensor, AFR/Lambda data is also logged. The logs are stored in your phone under:
Android/data/com.fsrtech.fl.tuneboss.mngr/files/TunebossData
Please see the section on datalogging for further info.
