Calibration: Civic Turbo CVT 2016, +6 psi high octane, EPA/CARB compliant

I have a 2016 US Civic CVT Coupe Touring. After doing a flash, all the indicators eventually went away as expected except the check engine light. I clicked on Error Codes while Datalogging but no codes showed up. Any suggestions? I tried returning ECU back to stock but it is still there.

Try using Online -> OBDII Diagnostics to find the code.

This morning I checked and discovered the CEL light was now off. Guess it just needed some time. Will update if light comes back on.

Thanks for letting me know about OBDII Diagnostics!
