I called the SC this morning and they saw the firmware update for my VIN related to the enhanced performance. They told me that there is no need to make a SC appointment since it will be completed through an over-the-air firmware update which is confusing since it seems like everyone else has had to go in for a mechanical adjustment as well. Thoughts?
This actually makes a LOT of sense. Given what we have seen, there is nothing except Tesla wanting to keep a CLOSE eye on how the first couple hundred upgrades went to make sure there were no issues. No better way to do that than to keep it so SC-visits only.
To date, and we need more info about what Tesla may be changing, there is nothing described so far that is not already part of the cars that have been sold for . . . well years. The contactors that were mentioned, Tesla swapped those out to a the new model and made them universal years ago. The old Tyco ones just could not stand up long-term to the heat and stress, and this was why some early cars were seeing pack failures (both of my early P85s had this problem).
If this is truly an OTA upgrade now, then this could be something easily applied to older S85 and P85 cars (possibly S60 - old pack as well).
We need more data, but the underlying reason I think this may be a software only patch (assuming preexisting hardware in place from upgrades as far back as 2014) is because of the work done by wk057 on his car that pretty much turned on Ludicrous on a RWD car and pushed the 0-60 time down substantially. Granted, he had to do some hardware modifications to trick the system, but the experiment proved that there is a lot of untapped power in these motors and that the packs can deliver that power reliably.
In a nutshell, Tesla has likely been conservative with software limitations on all but the PxxD cars, and now they are lifting those somewhat.
