Tesla hacker and Twitter user @greentheonly has speculated that it won’t be possible to retrofit current MCU 2 (Media Control Unit) Teslas employing Intel chips with the new and improved Ryzen-based processor that is used in MCU 3.
In an up-close inspection of a new Model Y’s internals Green stated that “retrofit for intel cars definitely looks impossible - totally different power and other harness and thickness of the unit.”
The news hasn’t been confirmed nor denied by Tesla or its CEO, Elon Musk, but if proven to be accurate it would most certainly disappoint a great number of MCU2 vehicles owners, who were expecting to be offered the possibility of an upgrade, in the same way current MCU1 owners are able to upgrade their chips for a $2,000 (plus tax) fee.
MCU (Media Control Unit) is the computer controlling Tesla’s touchscreen, processors, RAM (short term memory), non-volatile memory (long-term memory), the audio subsystem, 5 amplifiers, WiFi, Cellular, Bluetooth, GPS, the Ethernet bridge, multiple CAN bus communications, the LIN bus, USB ports and many more.
It handles every software operation, excluding Full Self-Driving/Autopilot, which are unaffected by which MCU version a Tesla is equipped with. All Tesla’s built after November 2016 are capable of Full Self-Driving.
MCU2 came out in the spring of 2018 (fall of 2017 for Model 3) as an upgrade to the NVIDIA’s Tegra 3 processor found in MCU1. All cars delivered after that point benefited from the improved responsiveness and extra features that came with the Intel’s Atom E8000 Series CPU.
From a technical standpoint, the two chips possessed entirely different architectures. The release of software update V10 highlighted the differences, as MCU1 owners were excluded from both Tesla Theater and Tesla Arcade. Effectively, MCU1 doesn’t support Netflix, Hulu, YouTube, or any other streaming services that may be added in the future. It also doesn’t support any of the games Tesla added. Additionally, the web browser on MCU2 is much quicker and more capable as it’s built on Google’s Chromium platform.
In summer of 2021 Tesla released the redesigned Model S with a more powerful infotainment processor MCU. At the time no one was sure whether this was Tesla's next generation MCU or whether it would trickle down to other models.
Then in late 2021 the first news of a new Tesla MCU chip generation started to flood the web, with reports coming from China of a new AMD Ryzen-based computer being present in newly delivered Model Y’s.
The new MCU is faster and brings noticeable improvements in responsiveness in the web browser, as well as while using video streaming services, such as Netflix and YouTube.

Last night Tesla finally launched FSD V13.2 with a bevy of new features for its early access testers with update 2024.39.10. While they barely missed Thanksgiving's floaty deadline, they still managed to deliver it in November, marking another big win for the Tesla AI team.
Early Access Only
FSD V13.2 started to roll out to early access testers - who generally get hands-on with the latest builds in advance of everyone else. They’re the equivalent of Tesla’s trusted testers who aren’t running internal builds - and they’re able to catch more scenarios outside of Tesla’s pretty extensive safety training suite.
If no major issues are spotted, Tesla will begin a slow rollout to more and more vehicles over the next few weeks. Assuming all goes well with this build, it could be in most customer’s hands by Christmas.
Of course, as a reminder, FSD V13 is still limited to vehicles equipped with AI4—and for now, anything but the Cybertruck. The Cybertruck is on its own FSD branch, without access to Actually Smart Summon and Speed Profiles, but with End to End on the Highway. The Cybertruck was recently upgraded to update 2024.39.5 (FSD V12.5.5.3).
FSD V13.2 Features
Let’s take a look at everything in FSD V13.2 - which is the build version going out now on Tesla software update 2024.39.10. While we previously got a short preview of what was expected with V13, we now can see everything included in FSD V13.2.
Start FSD from Park, Reverse & Park at Destination
Parked to Parked has been the goal for FSD for quite a while now. Elon Musk has been saying that it was going to be the key to demonstrating Tesla’s autonomy framework back with the release of V12.3.6 - when V12.5 was but a glimmer in the Tesla AI team’s eye.
Now, with V13, FSD has integrated three key functionalities.
Unpark: FSD can now be started while you’re still parked. Simply set your destination and tap and hold the new Start FSD button. The car will now shift out of park and into drive or reverse in order to get to its destination.
Reverse: FSD has finally gained the ability to shift. Not only can the vehicle go into reverse now, but it can seamlessly shift between Park, Drive and Reverse all by itself. It can be perform 3-point turns.
Park: When FSD reaches its destination, it will now park itself if it finds an open parking spot near the final location. Tesla says that further improvements are coming to this, and drivers will be able to pick between pulling over, parking in a parking spot, driveway or garage in the future.
If everything goes smoothly on a drive, users will no longer need to give the vehicle any input at all, from its original location to its final parking spot. No more user intervention other than supervision is needed, unless an intervention is needed.

Until now, FSD V12.5 and V12.6 have been using reduced image quality at reduced framerates to match the lower resolution and lower refresh rate provided by Hardware 3 cameras. For the first time, FSD will be using AI4’s (previously known as Hardware 4) cameras at higher resolution and 36 frames per second.
In short, that means better image quality for both training and in use and higher accuracy for things like signage and distance measurement.
Speed Profiles for All Roads
FSD V12.5.6.2 brought new and improved Speed Profiles to both city streets and highways, including the new Hurry Mode, which replaced Assertive Mode. However, on V12.5.6.2, there were a few limitations - roads needed a fairly high minimum speed limit of 50mph (80km/h) or higher. Now, that’s no more. City Streets has speed profiles for all speed limits now.
Cortex, Tesla’s massive new supercomputer cluster at Giga Texas, is now online and crunching data at a truly insane rate. It's one of the fastest AI clusters in the world—and it's dedicated to FSD. Tesla has 5x the training compute crunching away to solve the March of 9’s now that FSD is close to being feature complete.
Reduced Photon-to-Control Latency
Tesla refactored how it handles image-to-processing in FSD V13 - another huge set of changes to improve performance. In this release - a 2x faster photon-to-control latency, which is massive. In layman’s terms - that’s faster decision-making - it was already faster than a human, and now it's twice as fast as it was before.
Insane product push on the week of my birthday.
We refactored the entire system to drastically simplify the pipeline — direct photons to control — yet providing a lot more functionality under the same unify framework.
One of the features Tesla lists in FSD V13.2 is the ability for the vehicle to collect and share audio snippets with Tesla. The vehicle will ask you whether you’re okay with sharing 10-second audio files with Tesla so that the vehicle can detect emergency vehicles by sound in the future.
Camera Visibility Detection
The vehicle will now prompt you at the end of a drive if visibility issues are detected. The new option is under Controls > Service > Camera Visibility. Tesla will also retain images from the cameras when the vehicle experiences visibility issues during a drive so that you can analyze them later.
Another big update is a redesigned traffic controller - which makes for smoother and more accurate tracking of other vehicles and objects around the vehicle. We dug into how the traffic controller processes information in this article here, where you can learn all about how Tesla’s signal processing works.
One of the features V12.5 was supposed to bring was fleet-based dynamic routing. If a route was closed, your Tesla would turn around and navigate through an alternative path - and also warn the rest of the fleet of the closure.
V13 lets AI4 vehicles do this, and it's another element of the Robotaxi network that Tesla needs to get off the ground to ensure that once they do begin to deploy their first fleets - they function well. So far, with new job postings for Robotaxi Engineers and talks with Palo Alto to launch a Robotaxi service, things are on track for both Unsupervised FSD and Robotaxi sometime in 2025.
Upcoming Improvements
Tesla has mentioned a lot of upcoming improvements panel for FSD V13 too, which includes bigger models, audio inputs, better navigation and routing, improvements to false braking, destination options, and better camera occlusion handling. That’s a pretty big list for V13, so we’ll keep an eye on all these upcoming features that are expected in a future release.
What About Hardware 3?
Tesla’s previous roadmap update didn’t mention HW3 getting FSD V13. Instead, those of us on Hardware 3 will need to keep waiting and looking for Tesla to optimize another FSD Model - until then, you’ll be on FSD V12.5.4.2, which is still a fairly capable build.
Tesla has mentioned that they could potentially upgrade HW3 computers - not cameras - if engineers aren’t able to get FSD Unsupervised working on HW3. While there isn’t a lot to share here yet, it certainly looks like HW3 owners will be receiving some sort of free hardware upgrade in the future, but it’s not clear yet when or what they will be.
Keep an eye out in the new year for updates on what’s coming next with HW3. We hope to see an optimized V13 build eventually make its way to HW3 sometime in the future - Tesla has been working pretty hard on this, so let’s give them some time.
Release Date
For everyone who’s been patiently waiting to see more of FSD V13 since the sneaky reveal at We, Robot, you’ll be waiting a bit longer. This build is currently going out to early access testers, who serve as a critical step in Tesla’s safety verification process.
Once Tesla is comfortable with the rate of disengagement, Tesla will evaluate their results, make any final changes, and then begin rolling it out in waves. Fingers crossed, wider waves for V13 will make their way to AI4 S3XY vehicles and the Cybertruck by Christmas.
It’s that time of year again - it's getting colder, the snow might be falling, and the bells are probably jingling. And you know what that means? It’s time to find some holiday gifts for that someone special in your life.
Whether you’re buying for yourself or gifting to a friend, we’ve put together a guide to help you decide.
S3XY Buttons & Stalks
Aren't they S3XY?
Not a Tesla App
One of the coolest accessories for your Tesla is, hands-down, the S3XY Buttons. Using them alongside the Enhauto commander that comes in the kit can give you a massive amount of new customizability and control over your vehicle.
You can set a command for each button like folding your vehicle’s mirrors, or turn on/off your seat heater, but you can also control certain options Tesla doesn’t currently offer, like manually preconditioning your battery.
Sadly, these aren’t compatible with the Cybertruck just yet, but Enhauto rolled out a new set of features for the 2024 Model 3 Highland, which uses the ambient light strips to warn you about traffic or other situations.
We also recently covered the launch of Enhauto’s new S3XY Stalks, which add stalks back to the new Model 3 and 2021+ Model S and X.

Jowua Controllers
Wireless charging and Tesla compatible? They also look good? Every box is checked.
Not a Tesla App
Jowua makes a lot of fantastic Tesla accessories, but one of our favorites is their Tesla Controllers. You can get just the controller or a bundle. They’re comfortable to hold, the buttons are clicky and responsive, and they’re compatible with both your Tesla and your PC at home.
They’re multi-purpose, and the latest generation controllers can recharge on your Tesla’s wireless chargers too.

Abstract Ocean Hydrophobic Camera Covers
Super effective against water and grime - and a version for nearly every Tesla!
Not a Tesla App
Abstract Ocean also makes many accessories, but if we had to choose one that stands out, it's their Hydrophobic Camera Covers. They go over the rear camera of your vehicle and help keep mud, grime, and water off the lens.
We’ve linked the one for the Model 3 and Model Y above, but they also have versions for the Cybertruck, Model S, and Model X.
You can use the coupon code “NotATeslaApp” for an additional 10% off.
Tesbros Wraps
Carbon Fibre Console Wraps!
Not a Tesla App
Tesbros focuses on customization and cleaning, and they’ve got a lot of wraps. They've got everything you need to DIY wrap your vehicle, including interior and exterior wraps. So, if you want to wrap your vehicle or put on some carbon-fiber-like wraps on your dash, they’ve got what you need there. Check out their interior wraps here.
Also, check out their Interactive Wrap Visualizer to see what your Tesla would look like wrapped up in one of their many options - they sell both DIY and professional kits!
Tuxmat Custom-fit Mats
Perfect fit.
Not a Tesla App
Tuxmat makes custom-fit mats for vehicles - and they’re very high quality. They’re resistant to water, mud, salt, and whatever else you want to throw at them. They clip in seamlessly to your vehicle and look factory installed.
If you’re looking for a set of mats that will last, these took a lot of punishment in the author’s Model Y, and are still going nearly three years later without any wear or tear. Take a look at their mats at this link.
3D Spider Mats
Super sleek, super resistant, super affordable.
Not a Tesla App
Another option in the mats department is 3D Spider. Rather than the fabric-like feeling of the Tuxmats, 3D Spider offers thicker mats that will fit your vehicle nearly as well. They’re also a fair bit cheaper than Tuxmat. They make an excellent choice if budget is on your mind, and they’re nearly just as resistant as the Tuxmats above.
In terms of price-to-performance, these are some of the best Tesla mats you can get on the market - here’s a link to their store, but you can also buy them on Amazon.
T-Sportline Cybertruck Offroad Lightbar
A fantastic third-party lightbar option - without being permanent.
Not a Tesla App
The Cyberbeast’s off-road lightbar is taking a long time to ship—and there are plenty of AWD owners who want one, too. T-Sportline makes an off-road lightbar that mounts to the roof in a similar position as the OEM lightbar but without the glue on the windshield.
They also sell a quick disconnect and an L-rack mount, which means you can pull it off quickly and store it safely in the back of your truck when you’re not offroading. If you’re interested, shine your lights at this link.
Durable Sentry SSD
Waterproof, heatproof, coldproof, and dustproof. It'll survive it all!
Not a Tesla App
If you’re looking for a Sentry SSD that’s got greater capacity than the 128GB one that comes with your Tesla, look no further than the Samsung T7 Shield. It’s a rugged SSD that can withstand both heat and cold and is available in a 1TB, 2TB, or even 4TB capacity. They’re also sold directly on Amazon, making buying them easy.
Rally Armor Mud Flaps
They look sleek and protect more than the OEM flaps!
Not a Tesla App
The Tesla mud flaps can come off easily if you’re taking your vehicle down a rough dirt road or even in heavy snow. Rally Armor’s mud flaps are some of the best in the business - they’re flexible, solidly attached, and will keep your car from getting any dings from rocks or gravel flying up. Check them out on Amazon.
Touchscreen Protectors
Super easy to install, and you and you can get them in matte or gloss!
Not a Tesla App
The touchscreen in your car is the primary means to interact with it. If you or your passenger accidentally smash a phone into it, trying to drop it on the wireless charger, it's a pretty penny to get it fixed.
Instead of taking the risk, a tempered glass screen protector—available in matte or gloss—will help. The best part? They’ll keep those pesky fingerprints off, too, so you won’t have to wipe down that display as often.
If you or the Tesla owner in your life always gets out of your car and turns around to admire it, well, it better be clean. Car cleaning kits that come with rags, microfiber cloths, and all the chemicals you’ll need are a handy solution to getting that shine back on your ride.
If that’s not their style, go ahead and get them a car wash card for a local touchless car wash. They’ll appreciate it, and so will their Tesla.
We recommend this kit - it comes with all the basics and won’t break your wallet. You can add to it with a foam cannon and more tools as needed. You can buy it directly on Amazon.
Key Rings
A fantastic backup option.
Not a Tesla App
Tesla’s keycards are cool—nobody makes car keys this stylish. But what if you wanted something more convenient? You can also get a ring that will serve as an NFC key—it’ll act just like a keycard. Simply tap your knuckle on your car to get in, and then swipe your hand near the interior card reader to get going.
They’re waterproof, don’t require charging, and are a fantastic backup for when you leave your wallet and your phone in your car. Trust me, it’s worth it! Here’s a link to their site. We’ve also got a 5% Referral Code: FRIEND-QTS4D5R
Tesla Shop
A scale Cybertruck on some Cybertruck accessories!
Not a Tesla App
Of course, we saved this one for last. Tesla’s official shop has a lot of awesome stuff, from accessories for your vehicle to accessories for yourself.
If you’re aiming for some fantastic gifts, we highly recommend the scale models - they’re all really high quality and are fantastic display pieces. The author has a scale Cybertruck on their office desk.
Some of the links in this article may be a part of affiliate programs and/or offer you a discount. While they have no barring on what we decide to include in our gift guide, we may receive a small commission for items bought through some of these links, which goes toward supporting the site.
