FAQ – From aRacer
Q1: Why can't Quick Burn start?
- Ensure all connectors are properly connected and have good communication between each other.
- Go to iOS settings and enable the Bluetooth function. Then connect to the bLink in the aRacer SMART app (not from your iOS).
- Make sure no other device is paired with the bLink.
- Check if the ECU and bLink both have power.
- Ensure good wifi/service for the latest updated database.
- Use the proper model ECU for your bike; aRacer ECUs are not interchangeable.
Q2: Why can't my iPhone find the bLink?
- See the answer to Q1.
Q3: Why doesn't my phone link to the bLink?
- See the answer to Q1.
Q4: Why is the tachometer not working properly?
- In the US, there are only 2014 Gen1 and 2016 Gen2 ECU in the Grom market. The 2018 and up US Grom are still using the 2016 MAP/ECU file. Quick burn the proper version for your bike.
Q5: Why can't I see the change in tuning?
- The RC Mini5 with auto-tune is tuning the hidden base map. The auto-tune will make the base map approach 13.3ish.
Q6: How to troubleshoot?
- Perform Quick Burn first; 80% of issues can be fixed by Quick Burn.
- If the ECU light is on but the bike is not running, it does not mean the ECU is broken. Update the firmware or ensure the adjustment is set properly.
- Contact your aRacer dealer for tech support; we will work with your dealer for all tech support.
