Technical changes with MY26

[car_porschedriver_swiss]

I can't find any information about the J1.2 getting Android Automotive PCM. From what I have been told it will be an hardware upgrade of the MIB3 plattform to make it more responsive (faster cpu, more memory) and new software features. But I guess we will know in september since they close down everything at Porsche in august.

hopefully sooner. Mine is scheduled for delivery in August (in Switzerland) and will be model year 2026, but the lack of information from Porsche is a bit annoying to be honest…

From what I know they close down the productions lines in august for vacation, maintenance and upgrades. And the new Europe model years are delivered from september production onwards. But I have been wrong before

My dealer told me this week that my my26 Taycan Will leave the Factory beginning of August..

But it has the capability to be much better, because the software stack allows improvements, which PCM6 does not

Why not? Are you saying Porsche lost all the source code and design docs for PCM6 infotainment?

No, but I haven’t seen any improvement in 2 years, beside PCMs getting bricked when a tehnician tries to update it.

So I think it’s a safe bet in assuming that continuous improvement was not part of the initial design, when a software that is updated is a coin flip on wether the hardware breaks or not during the process of updates

Discussion derailed a bit on the PCM. Anyone aware of any other changes w/ MY26?

Nothing material as is typical on Porsches for annual MY change. J1.2 was it.

First, you stated that current software stack does not allow improvement, which now you're saying it's just not had a great track record, but is possible, so the stack allows it. Then you somehow equate Android OS to allowing updates? I have some news for you, Android software updated can be just as screwed up and brick you devices. Just like with PCM6, it depends whether or not you are updating the host OS or apps. Last but no least, just because it's Android, does not mean it will get updates any more often - there are plenty of devices running Android OS out there which don't get updates, ever.

Okey, let me be clear, which android device in the last 15 years has a 50% chance of bricking the hardware, requiring replacement?

Which software can you call "updates ready", when every time there's a coin flip of weather the hardware bricks or not?

We must have different definitions of what's means ready for improvement. Anything with a failure rate higher than the 0.01-0.1% in my industry is not acceptable, so 50% failure on the update process would mean to me it's not ready for improvement

You're arguing semantics with 0% backing. Post the links of android devices failing en-mass the update process I know first hand from my car from 2022, and from my dealer, that it happens often enough that they won't do updates outside of campaigns on these cars.

Post links of android stack that doesn't make a backup before update, and that doesn't restore the backup on failure. Because PCM does not do that, it doesn't have those capabilities.

Stop arguing semantics with straw man arguments

Why are you even arguing with me, when Porsche/VW agrees with me, and is moving away from the disaster that CARIAD is, and said as much in media? Why is Macan EV not on PCM6? Why are none of the cars coming in MY26 on PCM6? If it were designed for improvement, why did they not decide to improve it, and threw it in the bin?

 

[ze_shark]

And this 50% failure rate comes from where now ? Your usual "facts" ?

of course with over 200 cars updated only 2 bricked… but yeah

This sounds more like 1%. 1% is bad, but not a coin toss.

How about from 2 weeks ago?

This has nothing to do with the operating system. Sure, Android has some provisions for OTA updates, but you can do similar with any OS (I've worked on OTA updates for all kinds of operating systems, from low level RTOS to high level Android). OTA is a very complex thing to get right. Sure, you can update just the apps, but PCM has done that for years, mine has applied a Calendar or Weather app updates many times, no bricking.

See the first video, which was the fist thing that showed up when I googles "bricked android device". Google is your friend. Btw, that is a mainstream phone, there are smaller volume TV's, or music players, or webcams or other devices which sell less than some of the phone, but yep, they run Android.

Why is Macan EV not on PCM6?

Less work for Porsche. We're going to have to wait 6-8 years to see how this development turns out. Will Porsche support security updates for 15 years (expected life of a car)? It will Porsche Android infotainment become accidental victims of malware, like some old Samsung TV's which were no longer getting updates, but found themselves on the same network as someone's infected phone.

Let me be clear, I am not saying whether Android is a good or a bad choice, simply that choosing Android for your device doesn't mean it will have updates, or not crash during or after updates, etc.

Where the fuck did I say 50%?
You’re pulling numbers out of your ass and then acting rude to me over shit I never even said. Unbelievable. Try getting your “facts” straight before running your mouth.

Your video mentions you can simply re-flash android on it and all good

Sadly, you can't simply re-flash PCM on the taycan, because unlike with android, PCM actually destroys the hardware beyond software fixes.

But yes, let's see how the new OS will behave. It is definitely more "powerful" than PCM, with a larger knowledge base and with a larger pool of resources. And I would suspect easier to maintain and update. And likely easier for people to offer 3rd party support.

Or perhaps is it that the CO2 from “Global Warming” has entered your brain and killed what little neurons you had left?

I said it's a coin flip; and he was acting rude to me, not you. Sorry for that.

He just quoted you to say it's a 2% failure rate, and not a coin flip.

To me if it can fail at any point without any error or specific differential failure criteria, then it's a coin flip. It either fails or not. Any failure rate without a known cause, higher than below 1% is a coin flip.

@ze_shark it fails often enough that dealers refuse to update anything on the car in switzerland unless it's under a campaign from Porsche center. If they don't want to take a risk, because they don't know wether it will succeed or not, then, I would call that a coin flip

This thread got confrontational quickly didn't it.

If that counts as not bricking it, then PCM is never bricked either - you can re-flash the PCM using the the same steps as re-flashing the Android based one on Macan, both require PIWIS. Problem solved I guess. And no, you cannot reflash the Android based Macan EV with just your PC and a USB cable.
