Part 1: MapEV Diag

[prj]

I don't have any experience with iOS development. Some people I work with do, but developing this from scratch will probably cost north of 10 thousand $ with the way the economy is going.

The CarScanner app with a bluetooth adapter can clear the DTCs by using your phone. No need to carry enet cable and that adapter, etc.

Not sure if that sends a broadcast clear DTC request to all modules or not.

Could you publish the windows source code for just the ‘Clear All DTC’ to GitHub; and maybe someone can be inspired to write a quick-dirty iOS app for the same?

Source code is not needed, it's enough to just record with Wireshark what it does and look at the capture file.

It's not only "clear all dtc", you have to implement ISO13400-2 and do the multicast lookup and the activation handshake. And only then you can send a broadcast command.

OK.. so a lot more complicated than just sending a bunch of messages over ethernet. Understood.

Maybe a web application that does the job and it can then be launched from a mobile browser…

I’ll give Car Scanner app a go once I get my ASG module and see if it clears all errors. If it does, then problem solved.

Question - is it possible to be selective in the clearing of error codes? I have an intermittent issue with my eSound (Sport Sound) module and there are currently two errors logged, which I’d like Porsche to see - but clearly remove all others. Guess it’s not the end of the world to clear them all.

On some modules you can clear the codes only on that module.
Use the button in the middle (Clear DTCs) with the module selected that you'd like to clear.

But some modules, including the ASG refuse and only accept a broadcast clear request, which clears everything else as well.

Ok! Thanks for the info!

Is it possible to use a BT dongle, or does it have to be the wired one you recommend?
I use the Vgate iCarPro Bluetooth 4.0 with eFlow and Car Scanner Pro

You need ethernet. It does not have to be wired, there are also wireless ethernet bridges, but then the whole internet connection is difficult, so it is easier with a wired cable.

No, it will not work with <insert random interface here>. I will add this in bold letters in first post.

Buy the cable for $10, problem solved.

I have an old 2017 MacBook Pro that still works great. I just used Boot Camp (part of MacOS) to partition the drive and create a bootable windows partition. It requires you to download a Win10 iso file (you get this directly from the Microsoft site). The process was super easy and now I have Win10 running on my Mac. My OBD cable arrives tonight so I will test it and report back with results.

works fine too on a (very) old MacBook Air 2013.

Not enough space for Boot Camp, so I used Parallels Desktop 18 (OS 10.14 Mojave?‍), downloaded a Windows 10 ISO from Microsoft, and installed the virtual machine on an external hard drive.

Mac-only family here as well- resurrected an old Intel unibody macbook pro which I vaguely remembered had bootcamp that was unplugged for years, collected dust under my sofa and smelled like my dog, blew out dust with compressed air, thought it would not boot but it worked, ran the mapEV program with the ethernet cable attached to car’s OBD, and prj confirmed receipt of data. I received my tune yesterday.

Win 10 officially reaches end of support on October 14, 2025 so no new security updates will arrive after that.

For anyone using Boot Camp with an Intel Mac, you can actually upgrade to Win 11 even though Mac doesn't have the "required" hardware (TPM). To do so is pretty easy overall. Here are the steps:

• Install Win 10 using Boot Camp assistant
• Download drivers using Boot Camp assistant so that all Mac hardware works right in Win 10. Save to a USB drive
• After getting Win 10 working properly on your Mac, download the correct Win 11 ISO file from Microsoft (from your running Win 10 instance)
• Mount the Win 11 ISO (right click and select the Mount option)
• Run CMD as administrator and run the following commands
  • D:
    (or whatever drive your Win 11 ISO is mounted as - you can see this in the File Explorer app)
  • setup.exe /product server
    (this will launch the Win 11 installation and skip the TPM checks. Make sure you have at least 20GB of free space on your disk before trying to install Win 11)

This worked great on my Mac so I can run Win 11 and keep getting security updates. Credit to this reddit post for providing this information. I copied the important parts to this thread for people who don't want to follow random links.

I did a backend update on the tool. It should now decode the DTC's for all the J1.2 modules as well.

Any chance this software can clear codes or code other Porsches?
