    I also find after loading a tune the flare seems to be OK as well as the rest of the drivability when cold. As I get more time on it, I can tell the adaptive features are over correcting and then trying to adjust.

    I have an email into support to see if the newer files can get access to some of this. I don't have a response yet.

    I am also going to change to the newer fluid in the TSB this week. It seems to be acting up more when cold the more miles I put on it. We will see if that helps after a few flushed and a final filter change. I want to flush all the fluids anyway in the drivertrain to ensure proper level and get out and debris from manufacturing if there were cleanliness issues.

    Thanks a lot for sharing. Looking forward to hearing how the different fluid affects it. Hope it works well for you.
