Dear Tesla and Tesla FSD Team

[emmz0r]

1. I doubt Tesla will see this message. They do not respond to messages on this forum. If you want Tesla to see this message, you need to email it to Tesla.
2. There is no MCU3 AFAIK. Or are you saying that you want Tesla to give FSD beta testers a free upgrade to MCU3 if it comes out? But, I am not even aware that there are any plans for MCU3.
3. Are you posting this message just to make a point that you think the FSD visualizations are laggy?

MCU3 is real and is in new S/X,3 Y.
But it's wiring and form factor make it impossible to retrofit in older cars.

The autopilot computer is different than then the MCU. I understand your point but the AP computer is doing all the heavy lifting. With the included redundancy on the board I feel Tesla has safety as their paramount concern.

The Y is easier than the S. Isn’t the Intel Y liquid cooled? On the S you’d have to solve wiring AND cooling.

Also the FSD computer was not integrated in the S/X before last year, so some form factor problems besides cooling.

Didn’t we find out last year that they threw the AP computer redundancy out the window when they needed to start using the second node for additional computing power?

Well shucks, there goes safety.

Visualizations are irrelevant, they don't affect safety.

Tesla is saying that vision (cameras) are EVERYTHING. So if the car can't make out what;s on the screen how is it supposed to drive you anywhere?

It uses both to process things faster but if one malfuctions it switchs over to a limited processing version of the code that is meant to just get the car safely off to the side of the road using only one of them.

You’re confusing visualization with vision.

I guess I am but software should be able to give you just as accurate a visualization.

I guess I am but software should be able to give you just as accurate a visualization.

What the cameras see, and what the computer receives for NN processing is incomprehensible to humans. There is a NN transformer that converts the data into the visualizations we see, with a basic image recognition database. Suffice to say that the new ON can see obstacles, but the image recognition database may not know what that blob is. So, the car can avoid it, but visualizations may not show what it really is - hence the grey blob they added recently.

Dear Tesla and Tesla FSD,

I have owned a 2018 Tesla Model S (75D) & now own 2019 Tesla Model 3. I’m a huge fan of the FSD Beta program in which I am currently enrolled and testing with my Model 3.

Problem:

I do realize the software is in Beta, however I’m contacting you in regards to the hardware installed in my vehicle. Ever since the rollout of FSD Beta, I have noticed that MCU 2 (Intel Atom) is not sufficient enough to handle the visualizations and day-to-day use of the infotainment screen. Normally I wouldn’t let this bother me as I understand technology gets outdated (ie. iPhone slowing down from one generation to the next). However, with the FSD Beta installed on vehicles with MCU 2, it should be imperative for the visualizations to properly reflect real world changes - this is a matter of safety; if the visualizations are either laggy, delayed, or buggy; what sense of confidence does this leave the user to utilize FSD?

Solution:

I am requesting your team to please consider (at least) the FSD customers whom fully purchased this package, and perhaps the FSD Subscribers, to be able to have some form of MCU 3 retrofit - similar to Model S going from MCU 1 to MCU 2. For Model S, this was simply a quality of life improvement. However, for FSD Beta and future FSD users its a matter of safety and accurate reporting.

Conclusion:

I hope to hear back from your team in regards to this request and feedback as I’m sure I can’t be the only one with this is problem, as there are many sub-Reddit’s and TeslaMotorsClub users expressing visualization issues with older MCU 2 hardware.

Thank you for your time and consideration, I hope there will be a solution to this issue in the near future.

Regards,

Arya

Well Musk said on recent earnings call that HW3 to HW4 is not going to happen. So don't waste your money. FSD on HW3 will never be achieved as promised such as Robotaxi. Musk is a genius and knows that by that time, warranties will run out, and maintaining the car will become too expensive requiring the customer to buy a new car. We all got scammed. Was a Tesla fan but not anymore. I think there will be class action lawsuit coming their way next year

You need both MCU2 and HW3 for FSD beta to display things properly. You may have MCU2, but you may need the HW3 upgrade. I did these on my 2017 MX, and I can see the visualizations others see.

I have MCU2 and FSDb and I mean, sometimes it’s a little slow, but I definitely haven’t noticed anything extreme. Got to drive a loaner the other day with the amd (no FSDb though), and it did seem a bit snappier. You can very much tell the difference when using the theater. YouTube is abysmal with MCU2.

Ps, has anyone else noticed that Apple Music takes a considerable time to load songs-like 10 to 15 seconds. Can someone with MCU 3 weigh in here with their experience with Apple Music? I’m wondering if it’s a compute problem.
