FDIM Firmware Question

[slonison]

I have a question for you folks.

I am the owner of a 2013 Ford Mustang. I have the original 4" FDIM from the non-navigation configured vehicles.



I believe that this also came stock in the Ford Taurus of similar years



Now, here's where my question comes in.

When I turn on my car, the FDIM boots directly to showing the last radio station that was selected when the car turned off. Literally immediately.

However, if you take a look at this thread:
https://themustangsource.com/forums/f80 ... ost6675610

You will see that people are confirming that early models have no "MUSTANG" on start-up, while people getting the FDIM replaced have "MUSTANG" as a bootup splash screen.

There is also a person on reddit, who actually must have bought a car from someone who swapped in a Taurus Screen, because their screen says "Ford Taurus" on boot-up.
https://www.reddit.com/r/S197Stangs/com ... n_1_syncs/

So my belief is that the bootup lives somewhere in the Firmware of the FDIM.

My Specifications in my car are:

Part Number: BR3T-19C116-AB
Calibration Level: BR3T-19C116-AB
Hardware Number: AR3T-14D008-AA
Secondary Boot Loader: 8A8T-14D012-AA

In forscan, when I pretend that I am going to update the module, I have the following options for the Calibration Level:
AR3T-19C116-AF
BR3T-19C116-AA
BR3T-19C116-AB

So, it's pretty clear I have the latest Calibration level software that Forscan is showing, but is it possible there are more? The newer FDIMs that were released for the mustang all maintain the same part number of BR3T-19C116-AB. So I'm wondering, is there a way to brute force past the recommended list? When I choose the drop-down from factory is errors out
"Sorry, factory AS-BUILT file doesn't contain information about this module."

Any thoughts from the big guys over here?

I remember reading about splash screen logos in the IPC. These logos were relatively large image files and were located in a different file from the calibration level (I think). If nobody here knows the answer, try searching for Focus ST logo upgrades on various forums. You may find the file is in Hardware or Calibration files. Now, how do you know what file version to load? I don't know.

Very interesting and you are correct. This reddit thread shows the same FDIM in the Ford Focus with "Ford Focus" as the splash screen.

My experience dealt with the splash screen in the IPC, but the image file structure appears to be the same. There was a guy in the UK that wrote code for custom screens....that would be nice (never found that information again). Again, those files were larger than the rest of the firmware files.
