What OBD Device Should I Use?
The Speedweaver App currently supports most wifi devices on iOS and most bluetooth/wifi devices on Android. Our team is currently working to support bluetooth devices on iOS.
The best OBD Diagnostic tools we have tested are ScanTool OBDLink, Vgate and Kiwi devices.
Please note that some of the very cheap and generic OBD devices may not have satisfactory performance.
Also note that only bluetooth devices are supported, so if your device is BLE only and doesn't have support for bluetooth classic it won't currently work with the app.
Connecting the OBD Device
First locate the OBD port in your vehicle. It's usually no further than a metre from the steering wheel and is most often found directly underneath in the footwell. If you can't find it, consult the vehicle's manual.
To connect a Bluetooth Device to your smartphone, ensure bluetooth is on and visible, ensure that the dongle is plugged in and the indicator light(s) are on. Pair the device by selecting it from the bluetooth menu in your phone settings. You may be required to enter a pin which can usually be found written on the Dongle or in its instruction manual.
To connect a WiFi Device to your smartphone, ensure wifi is on and ensure that the dongle is plugged in and the indicator light(s) are on. Pair the device by selecting it from the wifi menu in your phone settings. You will likely be required to enter a password to connect to the Dongle's network which can usually be found written on the Dongle or in its instruction manual. Some wifi Dongle / smartphone combinations may require you to switch off mobile data to work.
Once the device is paired to your phone, open the Speedweaver App and navigate to Settings (⚙️ icon in top right) -> OBD Device Settings and choose WiFi or Bluetooth.
For WiFi option the default Host/Port configuration will show which is likely to work with your device - if your device requires a different combination you can change it here. For Bluetooth option you are given the opportunity to pick which paired bluetooth device you'd like the app to try to connect to.
After this, exit the settings back to the main screen making sure to save tap Save Changes when prompted.
You should now be able to click the Connect button and get started with the app!
When you connect, you may be given an option to pick which ECU to connect to from the list of ECUs the app has recognised. Please note that only one ECU can be monitored at one time.
