Modifying As-Built Data Guide

[Mike Pfeifer]

I have it on my 2019 with the latest sync 3 update installed.

I guess the reports of the APIM changing in MY 20 are true?

Just did a bit of forescanning.
Disabled the no key honk.

But, there is no longer the GT Ford Performance splash screen in the APIM.
In its place in position D is a generic ford oval.
I tried every number and letter in the alphabet. No joy.
So, for the Mustang there is only the Pony emblem splash screen (and GT 350)

07D0 02 01 xXxX X?xx xXxX
? Is the modifier.

Try 0Dxx (Pulled from another model)

Try 0Dxx (Pulled from another model)

Sadly, my factory setting was 06xx (pony animation)
Setting at 0Dxx shows a generic Ford oval.

This is the one I was trying to find.

Thanks guys, got the FP snake to stick with option 10.
The GT PP is gone.

 

[TexasRebel]

They pulled the GT screen with one of the firmware updates.

Used it as long as I could, but reverted to the snake just to confuse people.

This one is the best:

Just make sure you get an original one. There are cheap clones out there which don't work properly.

Ok so I got this and it's on it's way. I remember reading about changing tire sizes in the BCM but can't find it now. Can somebody point me in the right direction ? Thanks.

So this is what the hex line in the AB file actually looks like ;

1, 726-12-01 BCM/GEM Body Control Module / Generic Electronic Module (BCM/GEM), 014B, 083B, 55, Yes, 00000001 01001011 00001000 00111011 01010101, HU5T-14B476-HAB, , HU5T-14C184-AAK

Interesting.

I don't know the exact address, but if you open the "easy" BCM configuration, not the as-built, you will see an item called Tire Size, or something like that, and a numeric value. That's the tire circumference in millimeters. Apparently it's not exactly the mathematically correct value that you would derive from the nominal tire size, but it's quite close to it, within 2% or thereabouts. Increase or decrease that value by the same percentage by which your new circumference is smaller or bigger than the original one, and that's it.
You may get some DTCs after that, which will have to be erased. If you can't erase them, then you may need to do a PCM and/or TCM relearn.

Great. I'll check it out.

I took a closer look. This is it:

The stock GT tires are 255/40R19 front and 275/40R19 rear. This means a theoretical circumference of 2157.018 mm in the front and 2207.283 mm in the rear. The value stored in the BCM is somewhere in between.
I don't think it must be perfectly accurate, since obviously the real circumference will always vary to some extent due to tread wear and other factors. I think it will be OK as long as it's close enough.

Interesting.

01 4B 08 3B 55 is the only hexadecimal there.
00000001 01001011 00001000 00111011 01010101 is the binary representation of those numbers.

The HU5T... is a part number.
