Hey folks. I have a question. I just got my car back from the 5000 mile service and they did a software update. I noticed my mileage tracker, etc has been reset.
I might be imagining it, but the car feels a little sluggish too.
My question is: when the software gets reset/rebooted/updated, does the engine management also get reset? I feel that it learns your style of driving over time and adjusts better to how you drive after a few weeks/months. This feels like it is no longer the case.

Am I imagining this or is it true?
