Technical

The Tesla is the last car I will ever own, simply due to its incredible technology and comfort. I am interested in what you don't like about it though? Personally, I find it annoying that even with passive entry enabled, I am unable to tap any of the passenger handles to have only that one...

A quick Q for the allknowing roadster forum brain. Looking at the 2.5 vs the Sport edition there are a few exterior parts in higloss carbon finish (rear wing and parts of the hood to name) Would it be correct to assume that a normal 2.5 could get the same look if you stripped the same parts of...

Jason Hughes, wk057 on TMC and Twitter, is a celebrated Tesla hacker known for his highly-modified Model S. The car started as a P85, but Hughes upgraded to a larger battery pack and dubbed the car a “P90++”. Now, after upgrading the battery again, he’s calling the car the “first and only RWD...

Last night, I went to a magnificent private Model 3 revealing at Century City mall showroom, here in LA, prior to the public displaying today. We were welcomed with champagne and a ton of hors d’oeuvres. After some significant lubrication and conversation with multiple educated Tesla...

Here's an interesting test that Motor Trend magazine did. They compared a Bolt with standard, low friction tires and then swapped out to Ultra High Performance tires. As expected, the handling and braking improved measurably, but the range and efficiency dropped dramatically. They...

Update - after a busy week of analysis I have a PCB design in the works that is a drop in replacement for the BMB PCBs to allow a bricked pack to be safely trickle charged in car (or out of car). The Roadster has 99 bricks in series - the design is basically 99 fully-isolated charging circuits...

Since there are many members with a very good technical knowledge, I hope to have luck solving my issue... I have a roadster 2.0 from 2009 since 1 year, about 55000km and it drives fine - no issues up to now. My basic question is: Is the brake booster (power brake unit) controlled by the VMS? I...

Sorry if this has been covered already but I can't seem to get my Outlook calendar to sync with my MS. I don't use the native iOS calendar app at all. I use my corporate Exchange Outlook mobile client on my IPhone 6S Plus (iOS 11.2.2). I did run a test by adding a test appt to the native iOS...

I'd love to be able to grab all of the metrics / telemetry / etc from my Model S and store them in some time-series db (InfluxDB is just what i'm familiar with; it could be anything). I'm curious if other have taken this on and would be willing to help me out in getting set up. I'm a fairly...

Was thinking about vampire drain (M3OC has a topic about excessive drain, also reports from Norway). And I came up with just a software update. Tesla could add power saving (with connection drop) mode selection in the app (to all models, S, X and 3) So if vehicle is left alone for long, owner...

Ap 2.5 S/X have been delivered by the thousands. Model 3 is getting into many customers hands. So ^^^ topic ??!

I am looking for a tecnichal description on how to manually charge a bricked Roadster without removing the battery from the car. Tesla service is not an alternative, I know that Gruber offers such a service but they are not near and I would like to know how it is done. I tried to open the small...

In early 2013, I took delivery of a 60kwh Model S and in 2015, I had some battery issues which caused my service center to send my high-voltage battery pack to be remanufactured. In the interim, I was given a 60kwh loaner battery. After two years, I asked the service center about the status of...

Only had my MS for a few months, so in need of a little help. Just noticed a spot on the garage floor this afternoon, it appears to be a blueish fluid leaking from approximately where the front drive unit would be. In reading through some past forums, it could be battery coolant? It does have...

Used the supercharger 3 times between pickup (12/26) and 12/31. I was never charged on my credit card for that usage. I used the supercharger today for the first time this year and was immediately billed. Technically free charging until the end of 2017? Any other owners notice this?

I’ve been having an issue with our M3 unlocking and flashing its lights automatically, since my home is directly over our open air car port. My iPhone X is probably no more than 30’ from the car at any time, and the phone key connects just a little too well. Today I used the Tesla app to unlock...

The charging timers are disabled on all Tesla 3s. Early employee buyers had it and it was then disabled. The functionality seems basic and works flawlessly on my S.

I am a real fan of EV-FW.com It's super useful to track when other people get new firmware on their cars and I can start getting itchy for mine to get it too. We now have a new challenge. Model 3 seems to be on a very different firmware path to Model X and S. I am not sure who the owner of...

Has it been figured out how many CAN buses are present in the Roadster, and good ways to access each bus? (figure the OBDII port will give access to 1 or maybe 2 of them). My first interest is the battery monitoring system (BMS) from the battery - goal being to monitor a battery charging from a...

Hey guys, new to this forum but just looking for a bit of info on a project I want to pursue. It involves taking a kit car or ultra lightweight sports car such as a Lotus Elise (Yes I know this sounds exactly like the first gen Roadster), and installing P100D internals. In the article, it is...

Yes or no question ...o_O (Reason I ask is because M3 obviously has heating in them, but I’ve seen no conclusive evidence that MS or MX has it. Parts catalog doesn’t say if they’re heated or not.) Pic of heated B-pillar camera in M3...

Hi, I’m new to Tesla and to this forum. Sadly, my new model S started given these errors less than 2 weeks in !! Park assist unavailable power brake reduced AEB disabled Traction control disabled stability control disabled This (or some combination of these errors) started to happen every...

I usually keep my keys in my pocket when I'm at home and so I'm frequently triggering the auto-presenting front door when doing stuff in my garage without any intention of getting into the car. Sometimes the door eventually closes on its own and sometimes it does not. Last week it happened while...

It all started at a Tesla service center in Vancouver BC in the summer of 2016 when I was talking to an employee about the wheels. I asked why there was a difference between the 19-inch wheels and the 21-inch wheels in terms of efficiency. The rep told me it had to do with the contact patch, as...

I'm looking to buy an MCU (aka CID, the big center touchscreen). I need it to be in functional condition, but I don't need it to look nice, so things like screen discoloration are ok. I'm located in Europe, but I would buy from the US too. From the US you'd have to ship to North Carolina. It...

Any tricks to disengaging the electronic parking lock on a dead 1.5 Roadster? (my Roadster is fine, this is another one) I patched a 12V battery into things and the car booted up... the screen would go into Tow Mode but there was no thunk and after a few attempts it reporting a parking system...

So, Elon musk said the S/X would always be at the front of technology so it's a little disappointing to see Model 3s getting features S/X don't. If you watch this video you'll see the immersive sound has low/high instead of just on/off and that it has a new option, speed sensitive volume. I'm...

A few months ago didn’t we get a message from Elon saying that Autopilot is going to get some new features during the holiday season? I don’t recall 100% (also not talking about the FSD promise or any promise made pre-August) I just feel like I heard something about them giving us a fun upgrade...

So a good feature about Chill mode is that when running low on energy, it will help you to arrive at your destination easier by not allowing you to use extra energy by restricting the energy consumption when pressing the accelerator pedal. Coupled with Range mode, I would imagine it could make a...

Hola amigos, necesito el esquema del circuito eléctrico de cualquier versión de Tesla, tengo que dar una clase en la escuela, a quien me lo pueda facilitar se lo agradecería mucho, mi mail es [email protected], desde ya muchas gracias.

As we all know the 'new' bumper shields the front radar better from snow, however it can still build up over the radar. Has anyone added a heater to the front to prevent this for long roadtrips? I was thinking about it and I don't think it would be super difficult. Obviously a metal plate would...

Mijn Model S stopte er in Maastricht ineens mee, volgens Tesla een kapotte 12V accu. In het internationale deel een post: Immediate and fatal 12V battery failure De ANWB brengt mijn auto morgen naar Tilburg en dan gaan we het zien. 12V accu is paar maanden auto. We gaan het zien. Is is uit...

I'm reading the owner's manual on the Alpine IVA-NAV-10. I'm confused about some of the features -- how they work, are they actually available, etc. I have a 2010 Roadster 2.5. Does anyone have a link to a video that goes through the setup and operation? Thanks!

Tesla heating the front camera but not the radar basically disables the system making it unusable. This radar failure was roughly 5 min after leaving a parking garage. The still was later on in the day after some errands and things.

After my recent fender-bender and consequent repairs (all documented here), as of this morning I am getting the "Driver Assistance Features Unavailable" error message on my dash (picture attached). I was driving on AP1 happily (and without an issue) when the car chimed, turned off the cruise...

I’ve seen it discussed that charging will warm the battery up to allow for better temperatures for winter charging. Also I’ve read that charging before you drive can help you preheat the pack. But is it possible to keep the pack warm all the time by keeping the charge rate around 10A~...

I recently bought a used "as is" Tesla mobile charger on Ebay. It doesnt work, the car tells me the cable is bad which makes sense as the cable is in rough shape. The box turns green when powered on and appears to be functional. Everything seems to work correctly including the plug into the car...

Over the two and a half years and 36,000 miles that I’ve enjoyed my S85D, I’ve had virtually no problems. Even so, there have been annual inspections, minor recall notices, LTE and dual charger installations, etc. In all cases, Van Nuys SC has been heroic. Cars picked up, loaners left, etc...

Hey guys: Anyone have a technical drawing or 3d model of the Roadster hardtop? Need it for a special project I'm working on :)

Can't seem to get a clear answer on this. The ability to win back energy during braking is one of the nicest feature of EVs of course. However, many cars spend a lot ot time getting stuck in stop and go traffic each day. Therefore my question. See if you can fault my way of reasoning. During...

So, yesterday I hit a deer... My model S is a 2017, about 4 months old, with autopilot etc, also I have the latest update. Where all my driver assisted features sleeping? -because, it did not make a warning sound, it didn't brake, it did nothing at all... Off course I didn't ram straight into...

I took delivery of a new inventory 100D last Thursday. I noticed right away that the alignment is WAY off and pulling hard right. But...I’ve also noticed other minor things and I’m debating bringing them up because I don’t want to be “that guy”. Other issues: Rattle under the sunroof on driver’s...

Here is a item that will pretty much take care of those issues of fear on jacking up your Tesla X. I designed and made these initially for my own use as I do tire service on Tesla’s fairly regularly and was always afraid of the battery pack, pack shield and the side skirts. After a few dozen...

If a financial services professional(s) could be consulted on their practices in designed surveys so customers can self select themselves into different risk pools by their varying risk preferences and discount rates, the acceleration and deceleration times (or other subtle) features programmed...

What if some genius devised a diesel gen-set that could be mounted on a flat bed trailer to charge the battery on a an electric semi-truck so they could use the cheaper non-taxed off-road (red) farm diesel to move loads on public highways? Does Tesla have a position on the issue? It is...

I am doing a project for my graduate degree and I need some information regarding Tesla power electronic drives. Do tesla cars have braking resistors for use in emergency in case there's too much current going into the battery too quickly? This could occur if there is an overdriving load beyond...

I just bought a 2010 Roadster 2.5 and am waiting for it to be shipped. I downloaded a manual showing it can charge at up to 70 amps, but the seller charges at 40. What is the max charging amps you recommend? Thanks!

While I was recently visiting my home country the Netherlands, I stopped by the beautiful Amsterdam Tesla showroom. After talking with the sales team that Chicago is my new home since 7 years, I was asked whether I would eventually go back to live for a while in Amsterdam, and what I would do...
