Update 2022.24 includes various undocumented features

Tesla started rolling out software version 2022.24 to a wider section of its fleet (update 2022.24.5), introducing some appreciated new changes.
Tire Pressure
Before the current update, checking your tire pressure while the car was stopped was not possible. In order to prolong the battery life of the wireless tire pressure sensors, Tesla would only display the current tire pressure if the vehicle was in motion. Now the Service section (under Controls) will display the last known tire pressure for each wheel.
Keeping tabs on your tire pressure is not only paramount to your safety, but also improves efficiency while driving. An NHTSA study suggests that low tire pressure can reduce your driving range by around 0.3% for every 1% reduction in tire pressure.

With the new update you will also see the recommended cold tire pressure for the front and rear wheels, at the top of the screen.
Tesla recommends a tire pressure range of 40 to 45 PSI. This is often the minimum air pressure required to support your vehicle at its maximum load, depending on the type and vehicle configuration.
Reddit user Wugz reported a while ago that Tesla's vehicle state API would soon include data from the internal TPMS (Tire Pressure Monitoring System), so it could be possible we will soon have access to that same data via the Tesla app.
Uninstall Games

Update 2022.24 also enables the user to uninstall individual games, freeing up space on the vehicle's internal drive. In addition to uninstalling games, you can also view the size of each game, and which drive they're installed on.
When a game has been uninstalled, it can still be viewed as an available game in the vehicle and you'll be given an option to reinstall the game.
Depending on your model, the vehicle's internal storage ranges from 8GB (MCU 1) to 64GB for MCU 2, and up to 256GB for MCU 3. Tesla is expected to support external storage devices when they roll out Steam support.
Currently, most Tesla games in Tesla cars are Atari classics, including well-known titles like Super Breakout, Tempest, and Missile Command. Additionally, there are more recent games like Fallout Shelter, Sonic the Hedgehog, Cuphead, and Beach Buggy Racing 2, as well as some more traditional ones like Solitaire, Chess, and Backgammon. Users can enjoy some of these games using the touchscreen or the steering wheel and pedals.
GPS Directions
GPS directions have also been moved to the top left corner of the screen. When the vehicle's navigation is active and the maps are covered with another application, the next step in the directions will now be shown at the top left corner, instead of the bottom left corner.
Amongst other notable features included in update 2022.24, the company rolled out 'Tesla Profiles', giving you the option to tie your driver profile to your Tesla account.
This means some of your vehicle's settings, such as mirror, seat and wheel positions, will be able to travel with you from one Tesla to another. Read more about Cloud Profiles.

Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
