Ludicrous Upgrade Scheduling?

I don't recall that they drained the battery down to single-digit percentages before performing the Ludicrous update on my car. Of course, I wasn't paying complete attention and they might have done this after iPhone app communications with the car was lost. But I wasn't concerned about this.
I'm in Houston and received a call yesterday from one of the two service centers here (forgot to ask which one but when I signed up I selected the new North Houston center). The rep. stated the the parts for my upgrade have been ordered and he'd give me a call back to schedule an appointment when he has an exact ETA on them.

I'm low on the list, having put my deposit is a few weeks ago, so I know that I have a while to wait. OTOH, I decided to go for it!
Has anyone had an upgrade done at the Denver Service Center?
Keep up the reports!

I brought the car in just under 40%. My battery was drained to 20% as of 5 pm Wednesday. I checked a couple more times before the car went dark around 7 pm, but on those checks there was no further decline in the SOC. So I infer they had drained the battery as far as they were going to, which was to 20%.

Went on a drive a short while ago. 50 degrees, just finished charging to 90%, so the battery is warm. I don't have equipment for timings or the right place to do them. Noticeably quicker, but not a dramatic difference. I am nevertheless glad I did the upgrade. Some wheel slip from a standing start with the snow tires, which was not the case before. Definitely more surge when punching it at 50 mph. Curiously, the motor sound is a little different on hard acceleration (not in a bad way). Hard to describe. Maybe more whoosh added to the whine.

I'm sure the data is not as accurate as the data gathered with the in-car testing tools, but if you sign up for the currently free TeslaLog, you can take a look at some pretty good numbers.
I only signed up a couple of weeks ago, and then did some launches. Below is a graph and the details from one of them, just to show what is available.

Thanks. I didn't know it could do this. I saw TeslaLog mentioned in some other thread recently. It's the paranoiac in me, but my immediate reaction was concern about signing up with a website that would track my every move. I will take a closer look at it.

You can turn logging on and off as you desire, so if you wanted to, you could just let it track your car when you wanted to gather performance data.
You have a valid concern. You are providing your Tesla login credentials to a 3rd party, who _could_ do bad things as a result (or could track your movements, as you more specifically suggest). In this case, the developer is a Canadian, and as a fellow Canadian, I can vouch for him, all of us Canadians are angels
. In all seriousness, his service has had my credentials for a year now, and I haven't had my car stolen, broken into, or a new car purchased under my name, so I do feel comfortable vouching for him/the site.

Dropped it off in Dania last Saturday, but won't get it back until late this week, maybe Thursday. They said the engineer that was supposed to fly in last week wasn't able to make it, so they've been Skyping. Also said they were missing a part. Looking forward to getting the car back.

Whether or not you trust that the developer who is running the site has honest intentions is only part of the issue. The bigger issue is whether you are willing to bet that his site cannot be hacked. The unfortunate part is that your credentials have to be stored on the server, which means that if site gets hacked, all the credentials are now in the hands of the attacker. Now, Tesla summon does not have the ability to go far, but still, would you like your credentials to be had by a malicious hacker? The more owner credentials TeslaLog has, the more attractive of a target it becomes for hackers. Btw, even the Tesla site does not store your credentials in a way that would allow a hacker to recover your password. Unfortunately, for technical reasons, proxy sites such as TeslaLog have no choice but to to store your passwords rather than salted password hashes (session security tokens are an option but then you'd have re-enter your password to TeslaLog everytime your session expires or Tesla restarts their server). Tesla as a company also has more resources to dedicate to security than a single developer.

Interesting. I guess that makes the difference more likely to be P85+ summer tires in cold weather, although it did also feel that P85+ damping was excessively hard, while the P85D seemed to have stiffer roll bars, at least in my very subjective impression.

The only option for the truly hard headed amongst us was to swap the air for coil after delivery
