I had my 2018 SI service by the Honda Dealer for the AC control unit recall. They also update the PGM-FI SOFTWARE which erased my Ktuner tune. If I flash my tune back to the ECU will it erase the new Dealer PGM-FI SOFTWARE update? Can the new update be saved to Ktuner for when Ktuner sets it back from failed tune update or return to factory?

If you have a V2 clear tunes on your KTuner unit and reconnect to it. It will ask if you want to use the oil dilution update.

A V1.2 will ask you when you return to factory.

You can flash back to the tune any time.
