It's not getting connectivity on that pin or the ECU is denying the flash request. Feel free to reach out to support via email.

Preferences is for logging. ECU settings are in the tune parameters.

The features were written for USDM ECUs, so they won't show up on software that's not a matching codebase. I don't know of anyone that's tried a USDM ECU or software on the models outside of the country.

Flex Fuel is only supported on the USDM PZX ECUs, which you'll notice you can't actually check the flex fuel checkbox.

There is support in the software, but thank you for actually checking ahead of time!

If you have CAN Gateway enabled it will wake to check if the ECU is active, then sleep again if there's no response. If you have CAN Gateway disabled, because your vehicle doesn't have one, it will wake on CAN activity from the bus.

None of that has anything to do with bluetooth or RF interference.

Between the Accord we still have in the family and the RDX we finally let go of with a ton of miles on it, the 2.0T is highly reliable with a tune. Enjoy it.

The website was backed up to a previous version due to compromise. Nothing was changed for RDX.

The ECU determines maximum pressure in many ways. You're welcome to use Final Boost Target to manipulate the incoming target vs the outgoing final target.

The software would save a KTuner datalog file if you save datalog, not export to CSV, or have it set to a folder so it can automatically save datalogs recorded in the software. You can open the file with KTuner to verify you saved it properly before sending it to him.
