Do any of you Tesla owners have TeslaFi (or equivalent) data acquisition in your car?? The reason I ask is I need battery data to calibrate our heat transfer model. The particular question I have is the following: What temperature does Tesla heat the battery to when they pre condition the...

If you own an out of warranty Tesla then chances are you will be doing some of your own work. I successfully replaced my door handle so, when my MCU display got a bubble in it I decided to tackle it myself. All it cost me was the 500$ for a used display w/ touch screen. The display w/ touch...

I am trying to figure out how much thrust a certain cold gas thruster would produce. Assume specific impulse=60 seconds and a mass flow rate of 20 lb/sec on earth at sea level What is the calculated thrust??? Thx, George

We have a computer model of the Tesla Roadster. We calculated the forward thrust provided by the cold gas thruster, then added that thrust to the forward thrust from the front and rear axles and re calculated the accel times. I figured a specific impulse of 60 sec. Thats a bit lower than wiki...

Beautiful 2012 Dolphin Grey Tesla Model S 85kWh in excellent condition. This car has a newer "D" battery pack installed at 22,000 miles. Miles: 90500 VIN 5YJSA1CN4CFP01682 265 miles original EPA range - Charges to 249 miles @ 100% now. 85 kWh battery with rear wheel drive spec acceleration...

Per Teslarati: " Particularly notable is how well the Panoramic glass roof worked with the Model Y’s SUV form factor, allowing a full, unobstructed view of the sky. It should be noted that the glass roof does not have a center cross member such as the one found in the Model 3, effectively...

Ingineer hacked the M3 computer and found that the "full pack capacity capacity" was 76 kwh Tesla Model 3 gets hacked, reveals more details and great potential for dual motor/ performance versions Jack Rickard took apart a model 3 battery module and determined that the cell was 4.8 a-hr and a...

We just had a video from Jack Rickard on a Model 3 Battery teardown here In that video he estimates the usable a-hr rating of the M3 2170 battery at 4.8 a-hr and a usable kwh rating for the whole pack as 76 kwh. Ingineer hacked the M3LR and found a usable energy of 76 kwh...

I've got 2 Tesla's on my radar. a used Model 3 LR RWD w/ AP or an older Model S P85 RWD w/ Mobileye AP So I have a question for the owners of the old AP that ran the Mobileye platform: How does it compare w/ the latest and greatest AP? Obviously the new system must be better, lots more...

My 2012's warranty will expire in 2020 I'm assuming my warranty started when the original owner took delivery. Is that correct? How can I find that date? Thx, george

I replaced the left front door handle assembly yesterday in my 2012 Model S with a salvage unit ind the new salvage unit is working fine. Now I have the faulty unit on the bench and I'm troubleshooting what's wrong with it. Here's the symptoms of the bad handle assembly prior to removing...

There's a new video out about cost of ownership of a 2013 Model S: Tesla Model S Cost Of Ownership At 130,000 Miles at 2:26 into the video the owner details all the repair costs he incurred. he lists: water ingress on headliner cost to fix= 1367$ front suspension replacement= 2536$ Seems...

They can easily get into the front trunk area (below actually) but above all the plates on the bottom of the car. Great place for nest. Question: If I want to make an inspection of that area of the car in the front (Like where A/C comp is and stuff) Should I go in from the frunk area or the...

I've been researching this and there was a bunch of posts here on TMC about TM Spy. TM Spy is like Leaf Spy. It is used to pull data from your Model S such as battery temps etc that are not normally displayed. Most of the posts on TM Spy are a year or 2 or more years old. I notice that the app...

My engineering partner and I are creating a heat transfer model of the Tesla TMS. In order to calibrate the model we need data from Model S or X cars. What we are focusing on right now are battery temperatures during a super charging event. Obviously any other data that is available is welcome...

Any of you guys remember how this went down? All I remember is when it first came out it had the same 0-60 time as S85. Then Tesla did a software fix to get it into the 4's. The way I remember it, the software update was for ALL the 85D's. However if you go to teslainventory dot com and...

I'm trying to get the left front door handle assembly out but the top left nut is behind the glass. I saw a video of someone doing this on the rear door and they said the window needs to be all the way up but since the door is open the glass is down an inch or so. Plus it looks like even if I...

The cab/tractor of the Tesla semi has some panels that close the gap between the cab and the trailer. This is done to minimize aero drag. If you look at the first 20 seconds of the reveal you tube video they appear to be variable---ie they move depending on the yaw angle of the trailer. They may...

Do any of you out there know if wk057 weighed the model S pack when he did his teardown.....or the Model S 100. If he did I can't find it. Perhaps he just weighed 1 module. That would help as well. wikipediia has the weight of the model S 85 battery as 1200 lbs but I'd like a second source...

I can't get a good answer to this question on the internet. I live in Az so it would be fairly simple to fly over to Ca and purchase a Tesla and drive it back. My last Tesla I bot used in Texas. It was simple. Plate stayed with the car. He signed off the title and I drove it home, went to DMV...

Yeh I know it's a bit of a stretch but 2020 will be here before we know it. At that point we will own a car with no battery or drivetrain warranty. The main impact to said owners will be resale value. So here's the question: Sell now while there's still 2+ years of warranty left or Hold...

Hope this isn't a redundant post but I just called my Scottsdale service center and got that price over the phone. That's parts AND labor. That's good news for us older model S owners. Mine is a 2012 #1682 with 70K miles. 12K works out to be 140$/kwh. Pretty good news IMO.

On a volumetric energy density basis compared to 18650's in the 100D I've checked my math numerous times and I can't find an error. If the numbers are right it'd really not earth shaking news since the whole idea of the 2170's is to lower costs. If correct it possibly implies that Tesla...

I have a 2012 S right now and I'm fairly familiar with the options on the older Model S's....but this CPO is a 2015 so things are different in the options dept. It's a 2015 P90 D, mid 20's on milage and it has AP1. Could you guys look at the ad (link below) and tell me what this car DOESN'T...

Hello TMC people, George Bower here. I have been lurking and reading here for quite a while but have not posted. I write occasional article over at InsideEVs and was considering one on this subject but I need a second opinion. Here's my logic. See if you guys can find an error in it. Thanks...
