No, we had just got into the car, backed up out of a parking spot and were taking off to leave. Had only been in the car for 30-60 seconds.

Hey all -- Car: 2019 M3 Long Range, Dual Motor w/ software 2020.4.1 Last night I had a very weird and somewhat scary thing happen. We were backing out of a parking space, and I noticed that when I put the car into drive, the rear view camera didn't go away. I also noticed that every warning...

I set it with the app when the app showed 96%, but it charged to 100% this morning. Sorta misleading.. ehh, whatever. A bug or something. Thanks for the replies!

Just went to charge the car to 100% but the app shows it maxed out at 96%. Does this mean we’ve had a true 4% batter loss? 17k miles, 7 months old. Long range dual motor. Thanks...

Very nice of you...

Please let us know what your thoughts are after you've driven it a bit..

Since going from 4.4 to 3.9 doesn't seem like a lot, I had to explain that the closer you get to zero, how much more difficult it is so every 0.1 second that is removed, that's actually a lot. "...and Babe, this gets us 0.5 seconds - that's a lot!!" haha.. Here is how this is going to go down...

So.. Someone please buy this and tell me if it was worth it or not.. hahaha

For those wondering what the email looks like... The pic is below, but also here is the text so it becomes searchable. We have a LR AWD w/FSD so we didn't have any "Upgrades" area/button in our account. Now we do when I log into Tesla.com and click the manage button for the car. This is...

Got the email last night to buy the upgrade... lol. Should I click it? LOL. Have to get my wife to agree first..

Is there an easy way to see which rear motor you have? We have a 2019 AWD that we picked up on July 1st this year. Ours has a B on the eighth digit. Is there a way to make this a stealth? Not sure I'm following what people are saying about this..

Thanks for the reply. I know about the pushing of that button but like you, not sure if that constitutes the way we’re supposed to adjust the auto wipers which can add data to the neural network. It’s mentioned all over but doesn’t say how we’re supposed to adjust it to contribute to it. What...

So can someone tell me how the neural network for the wipers work? I understand that you set it to AUTO to make use of the neural network’s trained ability to automatically turn the wipers on and off. What I don’t know is how to make the adjustments to the wipers. If I have it set to AUTO and...

Just in case someone needs another suggestion, I found one specifically made for constant writing which comes from dash cams and home monitoring systems. It's been working great since July. SanDisk 256GB High Endurance Video microSDXC Card with Adapter for Dash cam and Home Monitoring Systems...

Hey all — For those that both use TeslaFi and Stats with the sleep settings on TeslaFi, what sleep settings do you use there? What works well for you such that you don’t miss any drives and such? I’ve turned sleep off currently on TeslaFi but I’d like to re-enable it - just want to see what...

If this range thing is really dependent on temperature - which is fine, I just wish they would tell us that. ...and the fact that there is this whole rounding issue - the two coupled together is what sends people over the edge trying to figure it out when there's nothing to figure out.

The PDF doesn't work well either. Do you have a Gmail account? If so, just copy/paste the data below the chart into a Google Sheet and make the sheet viewable by anyone with the link. Paste the link here. Then I can grab the data real quick and you can take it down. When you paste it into a...

I’ll plot mine tomorrow with the temps...

I need a copy/paste of all the data below this chart so I can put the data into a spreadsheet.

Since it’s Thanksgiving, I won’t get to this until tomorrow morning. Will post the results here.

If anyone else uses TeslaFi.com, I'd be happy to take all your charge data and do the same thing to see if we can see any patterns that work out best. Just copy/paste the data into a spreadsheet or something and attach it to a post. Just make sure the TeslaFi.com settings for your battery...

Here is a better picture of the data and why I chose 85% and 100%.

Ok, looking at the data more, trying to take a different direction from the data I have available to me... It looks like I have had much better luck charging over the long run charging to 85 and 86% than I have had charging to 90. Interesting that over many completed charges that 90% has done...

Hey that's cool! How are you seeing this data? Is this something that is only available outside the US? What other kind of data can you see? Can you share more about what you're using to get this chart?

Hm.. Sorry, I can't stop thinking about this. If the rounding error minimizes at the higher the SOC, I'm wondering if that is what helps increase the range. Here is a side question.. When I've charged to 100%.. It gets there to 100% and then sits for a long while, current still flowing for...

Ah damn, sorry to hear that. It's a real bummer. Not sure why, but this whole thing really bothers the hell out of me. I feel like I can't just leave it alone and roll with it. Really bugs me. I guess I don't have any choice though.. I don't want to keep screwing around with it and end up...

Happy Thanksgiving! Yeah, that's what I think too.. It depends when the charging stops - not how much it was charged. Which is why I started charging and stopping to see if I could figure things out. I dunno, I'm at a loss at this point and feel defeated. lol I'm not sure what to do except...

Letting it sit overnight didn't seem to have any benefit. Starting to think that the rounding error is all in display which is why I can't stack on top of each rounding error. Some people in another thread say they've fixed theirs but I didn't think about the software version they were on...

Hey @Sherlo, can you tell us what your estimated miles at 100% are currently and also what version of the software you're running? I didn't think to ask that. I'm on 2019.36.2.1 and don't seem to be having any luck.

Charged back up to 50% so I could see things happening. This was the best I was able to do since the rounding error is smaller at this level. Now the question is.. Can I build off this as it's new "base". Will see tomorrow I guess.

Here is the dilemma I have.. I can't see anything under 50% because TeslaFi (or the car, or someone) doesn't log data for charges under 50%. I've done what I think I needed to do and the max range is now 296 in Stats. I guess I should just let it sit there overnight and then charge it to 50%...

For sure.. I really wish I could see the charge data for our car on TeslaFi. It won't show anything less than 50%.

Unfortunately, TeslaFi.com doesn't show any charge data for less than 50%. :-( Here is the screenshot where I stopped the charging at which I hope helped kickstart this thing... Take a look at the red box. I guess I'll have to wait until tomorrow to charge to 50% to see it reflect on this...

With this first try, I'm going to attempt to raise the "Estimated Range at 100%" up to about 297. Here is what I'm shooting for. Will see if I can get there or not..

It's all good, I'm doing most of the observation from the usual cycles I do on a daily basis. Our car gets driven around 115-150 miles a day so it's easier for me to see this stuff over a shorter amount of time. I've maybe done two smaller cycles for this which isn't much. My wife does the...

Thanks for posting - and a great question. I talked with a SC the other day for a long while about this and he told me that when the car sits for some amount of time (the amount of time wasn't disclosed) that the battery pack will stabilize and the car will take readings at that time which...

Also for those following, when you use the car and the battery level and miles drop, you can see this number jump around in Stats for iOS. The lower the SOC gets, the bigger it jumps around. This is what I'm trying to target the next time I charge. I'm going to run down to 20% which will...

I understand what you mean but I'm referring to the "Estimated Miles at 100%" which is used in TeslaFi's "Battery Degradation Report" which seems to be also reflected in the car. If what you say is true, I should be unable to change the miles shown in the car when you have it set to show miles...

Well, I plan on using Stats for iOS since it gives live updates from the car during charges. Since the rounding errors are greater at lower SOCs, I'm going to try to start charing at 20%, then literally watch Stats and after a few minutes when I hit a high point, stop the charging for the night...

Oh when I was down in the sub 10% range, the rounding error is HUGE. This is what I'm saying, I think they're using that rounding error in their data and that is a problem. This would explain the such randomness that people see, up and down. It's all over the place. If what I think is true...

I went back and looked at some old charges where I lost range in a single charge. It appeared that I lost range because the charging stopped on the wrong side of the rounding error. Here is a chart I made that shows the rounding error in a single charge. If I would have stopped the charging...

Here is a shot of my overall range and showing that I was able to create an uptick in my range just by stopping the charging on the right side of the rounding error.

Some additional thoughts... Since the rounding error grows as the SOC goes lower, this may be why those who have been charging to lower % numbers have experienced a rise in their range. For example, I've been at 288-290 for a long while but just this morning but stopping my charge at just the...

Hey there.. Many don't want to partake in the figuring out of the range loss conversations and trying to see if there is anything we can do about it. Which is fine, we all have that choice. For those that are interesting in playing around with things like myself, I wanted to throw these...

I heard that the cheap one doesn't have spring loaded contacts on the inside so they weaken over time. The where the wires go in, they’re not strand friendly so the strands spread out and they get crushed which decreases the contact area quite a bit and of course, generates more heat. I had a...

Anyone have any more positive results by charging to 60 or 70%?

Yeah they said to keep charging to 90% and that it would take a month or two for things to stable out. That drives me insane. I'll change up when I charge, but will just keep it at 90% I guess. I wish they would put some time into this to see if there was anything they could do to make this a...

He didn't say why it only measured voltage at the lower levels. He said the readings are separate for the low and high end of the battery so it is good to let the battery "settle" at both ends so it can take the measurements it needs. Last night it sat at 26% until after midnight when it came...

So it doesn’t heat it up when charging with AC at home? If that’s the case I wonder why or why not?

I really wish they had this app for iOS, I'd buy it in a second I think. You could learn so much about this car this way.
