Tesla SC notified me at 100 that my car was ready. Just under 5 hours. They must be getting good at these computer swaps. I had it in for brake fluid service too but after testing it, they informed me no need to change at this point so only thing out of pocket was cabin filter replacement. On the retrofit, all of my settings were lost including Homelink. I had to pretty much set the car up as if it were new. Back home and plugged in downloading map update -- must be huge file because its taking awhile so assuming when done, 12.6 will be pushed or atleast I hope.
