There is always a chance, everyone can quantify what that is for themselves.If we all make a wish for MCU2 and APE3 upgrade on New Year's, maybe we'll get it?

In all fairness, the MCU never had to be the most bleeding edge tech. This is what do many people miss. It just had to do it's job quickly and reliably. Quality is conformance to requirements. There are software improvements that Tesla makes that don't require any speed increase at all, but then there are others (like dash cam), that require large amounts of processing power. I'm a firm believer that there is a point where the MCU doesn't have to do everything and nor should it. But the stuff it does do, I want it done fast and the same every time without crashing.I think in general this was poor future proofing by Tesla when they designed the MCU to begin with. Automotive tech can never keep pace with IT industry tech. The market just moves too quickly. The Tegra3 was over the hill even before the first Model S hit production. Even now, the Atom processor used in the MCU2 won't win any speed or processing power awards.
The MCU should've been designed so the wire harnesses/connectors were standardized from the start and separate from the processing unit. The actual brains of the unit (e.g. the CPU/storage/video) should've been a swapable board much like their HW3 computer supposedly is. More importantly, it should've been a user-serviceable component that customers could opt to purchase and change out on their own.
But I digress...
Technically, both ape3 and mcu2 are "plug and play", but you still need root access in order to change car configuration on the gateway to tell the car it has new hardware. That's hard to come by, so you can't just drop in hardware and think it'll work.
For better or worse your in it..... IF your service center really would do it then it's pretty easy for them. Toolbox has a function to copy out the old data from your existing MCU then they do the hardware swap of the MCU and the IC, or maybe you have to do this part, not sure how far they are bending for you. Once the hardware is in the gateway gets updated and the configs pushed on to the new MCU. I am probably missing a few things in here still but that's the long and short of it. If they do indeed perform the swap for you let us know! I'm sure just about everyone from this thread will be swarming them to get it doneCan you point me to a thread discussing this? If it was just.a matter of updating my MCU, I’d do it in a heartbeat, and I’m pretty confident that my service center would update the config. I thought there was a bunch of other stuff to be done as well. IC, harnesses, etc. I’m in a 2017, hw2.5 S100d, so should be the easiest of them.
I don't have a thread to point you to. I have an mcu2, ic2, tuner, and model S wiring harness on my floor though. Pretty sure I'm right.Can you point me to a thread discussing this?

They will not. Service center will not perform any changes where an MCU was not obtained from Tesla, ie: junkyard, wrecked car, etc.Can you point me to a thread discussing this?

Don't forget to mention they won't sell you MCU2 if your car has MCU1....
Positive cash flow from selling; negative cash flow from support or investigating problems; or negative PR when things don't work and the owner doesn't cough up what changed and they get written up in articles.That's a weird attitude, money is money, right?
-or is money from a mcu1 guy not worth as much?
v6 was the fastest in my experience, every new release got slower. So while those may gave been just changes (not all improvements, especially v9), they definitely required more processing power every release. My guess is Tesla just went with web technologies, running a myriad of abstractions layers in exchange for quicker coding and cheaper source of labor (a lot more web programmers out there vs. embedded). I still have the original Microsoft Surface, with the exact same Tegra chip as MCU1, running with tighter thermal and power restrictions, but it runs smooth, with snappy UI, and oh, it can play Netflix or youtube just fine too. Of course it uses native optimized Windows RT apps, not web apps - still not bare metal embedded which can deliver even more performance.In all fairness, the MCU never had to be the most bleeding edge tech.

Yes, and thermals.No doubt power usages was also a consideration. Certainly emphasised on AP day.
Tesla likes to package things, so for example they will not sell you the Tegra module for MCU1, but will sell you a whole MCU1. So, you can absolutely buy an MCU2 from Tesla, but you may have to pay for a much larger package starting at $79,990That's a weird attitude, money is money, right?

It is not a straight forward as you try to make it.

Have you noticed how the internet media just loves to flog every Tesla crash especially if AP involved and fire especially if battery involved? You never see the headlines “Ford Fire!” or “Ford Crash!”Well then, tell my why Ford motors don't have a problem selling me parts for a focus if I own a mondeo?
-it is that straight forward, I have money and want to buy a part with partnumber xxxx.
Never ever had a problem with buying parts to whatever, even if I don't own a car that the part fits on.
For what the regular seller cares, it's my problem if I don't get it to fit where I want, hell I even could use it as an anker for my boat if I wanted to, and the seller still wouldn't care...
Ahh, but if I trade in my S, the package would get cheaper I hope
Ford and the like generally have PLENTY of dealerships with service department to handle problems (and collect your money).Well then, tell my why Ford motors don't have a problem selling me parts for a focus if I own a mondeo?

You won’t, because they won’t sell it to you.No problem. I’ll buy it from them.
Open your perception of the situation to where Tesla is at.
