Sync 3 and 4 Bench Harness Project

Working on completing this project. There is a huge update coming soon! A few more features & a controls page going up soon that will allow users to create templates for vehicles & flash the device over USB.

Is there by chance any way to trigger the update screen on sync 4 with this bench? Its pretty much locked behind FDRS at the moment in cars. I’d be interested in seeing if its possible to send a signal through the obd port to trigger the update with usb feature. if theres any info itd be much appreciated and a great help! awesome project!

Yes actually, In theory. I assume the GWM tells the APIM an update is available, now how it does this? Unsure… Im not sure if its a default can message…Or…More complicated like a signed message of some sort sent to the GWM then over the “Ethernet” to the APIM. I do know a signed Cert with VIN is needed no matter what but that’s easy enough to generate & can be tricked(I believe).

Ive generated an update via FDRS pushed it to a USB drive and attempted to update an APIM on the bench but no luck. Hence why I assume the GWM or FDRS play a large role in authentication/initiation. But what do I know!! These are all just my assumptions, I haven’t dug into it much…

That would make sense, We’ve been trying to update sync 4 firmware In the mustang forums, FDRS does push it like it’s supposed to but it does not install correctly which is why I’m interested in a possible workaround. appreciate the reply!

Interesting! Do you have a link to the forum? Also what do you mean by “correctly”?

It’s mainly in a discord for the forums, I probably should have mentioned that :sweat_smile: And by correctly, its only installing one of the firmware files out of like 15. It could be something to do with the VIN Certification, but I feel it wouldn’t install anything if that were the case.

PM me an invite if possible, I’m Interested! I have successfully spoofed the VIN on the bench but how much the APIM actually cares? Who knows… I would also like to investigate how FDRS lets the APIM know a Update is present or expected.

That’s great. It would be perfect if the firmware could be modified to add languages ​​for countries not currently available in the firmware.

Are you referring to my control interface or Ford APIM software?
