Info for UE owners: I've just seen that there's a newer map version for UE (P410, the previous was P390 that I installed in March). I've downloaded it from the link of @Ken G (thanks again), in the next days I will try to install it and check if it's a good version.

Installed. It works.

Hmmm, I have never heard or seen those steps, so I will share these, which I have used on multiple PCM upgrades, HTH.

Here's a photo of the instructions I got off the MIB site:

Here are a couple photos of what i see on the map & nav screens also:

Note that the 'Nav Is Loading" message never changes.
I have had no time to actually dig into this so this is just for informational purposes. I am hoping to spend some time on it this week or weekend.

Please don't use those instructions they are incomplete at best, use those that I posted in post #1596.

As for the images you shared in the 4.5" TFT, I am not sure what you are trying to show there, you should be monitoring and checking the process from the main PCM screen not the 4.5" TFT.

@CaymanMatt , did you have OEN NAV from the factory (sorry if I asked this before), what year is your Cayman? No Video Signal would indicate that you do not have all of the hardware for OEM NAV, specifically the LVDS cable from the PCM to the cluster.

I will use the instructions you posted. Where did you get those instructions?
I'm not monitoring anything since the install was done weeks ago. I'm just showing you what's in the TFT for the nav. It does show a little bit differently than what's on the PCM.
My car is a 2018 and it did have navigation from the factory.

Ahhh I understand, that is strange, almost as if it does not completely initialize NAV. As you car came with OEM NAV nothing regarding it other than enabling lifetime maps should have changed. I wonder if the NAV DB is corrupted, what version do you have on the PCM?

Regarding the instructions you posted, IIRC they are from MIB Solutions, unfortunately as things changed and revisions were made the old information was still out there. The version I posted was what we decided on as we were testing the newly minted AIO release that was scripted to autorun and contain all of the patches for the various versions of PCM firmware (circa spring 2022), previous to this MIB was used and you had to manually load the patches that matched your version of firmware (this is where I got involved testing solutions), as you can imagine the probability for error was high with people thinking similar was close enough! AIO eliminated that process and made the update a lot more user friendly. But you still you have to use the AIO version relevant to your geographical location and the NAV DB that goes along with it.

FWIW, here is the approved YT version:

I do appreciate the time you are taking and assistance.

I'm curious what max voltages are being seen from the battery charger when others are doing the MIB update. My charger is older, although it does have an AGM setting on it, and seems to be putting out higher voltages than I expected. I'm thinking I need to replace it before doing my next round of updates.
Thoughts?

Unless your battery is old and nearly worn out, my advice is not to use any charger.

In the past 18 months, I've installed MIB AIO and map updates, plus lots of 431X coding, on two '17 718s and one '21, all of them bought used with original batteries. I never used a charger.

With lights and fans turned off, the power these activities consume is trivial. And the battery has a LOT of capacity. The only time I ran one down was when I let the car sit unused, locked (alarm set), for over 7 weeks.

I have the impression that some folks hesitate to do these easy upgrades because of the added hassle of a charger, or the confusion of too many choices in chargers. Or they're unsettled by the harsh warnings about things that might go wrong. It's all wasted worry.

I appreciate that the generous authors of these brilliant solutions wanted to avoid blame for anything that might go wrong. But in doing so, they went too far, I think. So many warnings about 'bricking' your PCM. I doubt anyone has ever 'bricked' their PCM running MIB AIO.

In the old days, when people accidentally left their headlights on, it would take hours to run down the battery. And that was with incandescent lights drawing on old-tech batteries.

It is very hard to mess up the MIB AIO install. And your battery is not even breaking a sweat.

Go forth and conquer!

Thanks for sharing your opinion, but to be clear there have been problems and what you refer to as "bricked PCM's" that have happened in the course of doing the AIO update. I get the feeling that because you personally haven't experienced the problem or been involved in trying to restore a compromised PCM that it hasn't happened, again untrue.

Adding the extra margin of safety is so easy to do, advocating that it is unnecessary just provides an opportunity for a problem to happen, not sure why you would suggest undertaking the process without a charger especially if one is available.

Your comparison to the old days and incandescent light doesn't have merit when it comes to reprograming the various modules and indeed the PCM in the newer Porsches.

I am glad that thus far you have escaped any issues, but it is a prudent move on many levels to use the proper processes and supplemental power when programming a modern Porsche. BTW, updating the NAV DB is not programming it is simply a file transfer and therefore much less restrictive in nature.

My 718 is a 2018 with the original battery. It's been on the CTEK for most of its life but I still don't trust it implicitly.

In my eyes, connecting a charger during the upgrade is a small cost to pay. However mine is an older charger and I do not necessarily trust it anymore. When I did the original MIB update, it put out over 15V at times which really worried me. That only happened for a short period of time but it caught my attention. Today I hooked up the same charger with plans to do the restore. It's a Craftsman that I've had for 15 years or so but it has 10A & AGM mode. The charging voltage immediately started climbing until it passed 15.5V and was approaching 16.0V. That's essentially when I unplugged it. I tried it in both the AGM and Standard modes with the same result.

This is why I'm asking the question.

Thanks for all the assistance and knowledge.

Ahhh, I would say that your old Craftsman does not have the the appropriate voltage regulation circuits for use on your Porsche, Personally I wouldn't use it. Depending on what you are doing, is there a reason you don't just continue to use the CTEK unit, which model is it?

You say "the next round of updates", are you referring to AIO or Porsche module programming?

Porsche specifically recommends a stable high current capable battery charger when doing feature/module programming or flashing modules on the car, usually in the range of 90-100A at 14.6v

You ask about max voltage, that does depend on what is happening to the car at the time, the alternator will supply around 15.5v when charging while the engine is running, but I would also be disconnecting a charger that was supplying 16v

I have a CTEK MUS4.3. I can do 4.3 amps and I don't trust it to be able to cover what I need to do.
I am going to do a restore and hope that gets me back to where I was before I did the original failed AIO update. I will then be doing another AIO update.

I did all of my work with a MUS4.3, because were are only programming within the PCM the current requirements are within its capacity, especially if you start with a charged battery and turn off all unnecessary electrical draw. Higher current or more capable chargers are only generally required for module programming and longer sessions. The MUS4.3 should be fine when starting with a charged battery,

I would have to look back at the thread to see what problems you encountered, but have you simply tried to re-run AIO?

I'm all good with everything you say. Thank you! I certainly broke some rules during my installs. The AIO just sloughed it off and got the job done when I let it.

I'll say my knowledge of AIO is limited to this forum, and I've surely missed many posts. On that limited basis, and my three cars, I formed my doubt about the warning. I'm really sorry I've missed reading about them. People should know if there's an appreciable risk.

But you were maybe involved in such a case I take it? Any links? I'm keen to understand and correct my thinking. If it's just too risky to do this stuff without a charger, then I'll stop pushing my luck and get with the program!

 

[ReidMcT]

Oh, wow, I'd be wincing seeing that voltage. Right with you! I ain't the charger expert, for sure but I'd have pulled the plug, too.

I have not rerun AIO because I did not want it to overwrite the backup it created and I don't know if I can store my current backup elsewhere and then reload that backup to the SD card for use at a later time. The access rights to these files as we know are highly dependent upon starting locations. It seemed better to attempt the restore and then restart from scratch.
FWIW

Yes, these backups are important, without them it is tough to go back, you would have to have base code and manually reload things. So best practice is to make a copy of the back up and save it on your PC. And yes you can definitely use that copy of the back up with a fresh copy of AIO and go from there. Access rights don't really apply in this case.

After securing your back-up re-running AIO should be OK.

Are the details regarding the problems you had during the first run of AIO in this thread (which post)? Also the details of the version, type of SD card, battery charger, etc, etc.

It's good to know that I can save my backup and then reuse it at a later time. Yes the details of the failure are in this thread. Basically it's everything worked fine until the very last power off of the PCM. It never came back and I ended up just turning it back on myself. I'm guessing these issues are all caused because I did not have the ignition turned on, which as you know is how it was noted in previous instructions.

I'm going to offer up the following suggestion. How about a separate thread that just has current MIB instructions and links to locations? There are about 100 different places (maybe a slight exaggeration but not by much) to find this information and it's all different. Trust me, I've spent a long time trying to find this and I still screwed up. Your most recent posting here with those instructions seem to be what we want so if that's the gospel, let's put it someplace where it's easy to find. Sort of like the X431 programming guide.
