This guide will help troubleshoot common eFlexApp Bluetooth connection issues. If none of these solutions work, please contact us at support@eflexfuel.com
Some vehicles must be powered On with the engine running to power your eFlexFuel device. You may need to turn your vehicle on to establish a Bluetooth connection.
Inspect your eFlexFuel harness ground point
- Confirm the ground wire has direct and clean contact with a stable ground point. A bad ground will prevent a stable Bluetooth connection with your eFlex device.
Delete the eFlexApp and Re-Download/Install
- Try deleting your eFlexApp and re-downloading/installing the app.
- Establish the Bluetooth connection in your phone's Bluetooth settings before opening the eFlexApp.
Establish a Bluetooth connection in your phone settings first
- Before opening the eFlexApp, go to your phone's Bluetooth settings.
- Remove "eFlexFuel" if it has been previously paired.
- Add a new device and look for "eFlexFuel".
- Once successfully paired in your phone settings, open eFlexApp and search for Bluetooth signals and connect.
Confirm Location and Bluetooth permissions
- Verify that you have authorized the eFlexApp to use Bluetooth and Location.
- Location may be required to scan for nearby Bluetooth devices.
