It seems some data in the 2015-2017 cyanlabs ACM and ABS databases is wrong?

I have been studying cyanlabs asBuilt DB and I noticed that data regarding ACM and ABS might be wrong or different to factory asBuilt data in some cases especially ABS and ACM modules. Here are some examples:

Case from ACM:
section: 727-01-01: xxxx-x*xx-xxxx
functionality: Front Tweeters (FT), Chime Strategy (CS), Active Noise Control (ANC)

My 2017 Ford Fusion Sport’s ACM factory asBuilt says: 727-01-01 10A0 9200 0072,
CyanLabs DB value: 2=FT Not Present, CS: North American, ANC Present, USB Not Present

According to cyanLabs DB, I don’t have Front Tweeter but in reality I have a Sony Sound system and front tweeters actually work.

Another case from ABS, here I see a lot of contradictions:
section: 760-02-01: xx*x-xxxx-xxxx
0=Reserved
1=2.7L GTDI
2=3.5L PFI
3=3.5L GTDI
4=5.0L PFI

functionality: Engine

My 2017 Ford Fusion Sport’s ACM factory asBuilt says:760-02-01: 172C 4111 00FF,
CyanLabs DB value: 2=3.5L PFI

According to cyanLabs DB, my car has a 3.5 PFI engine but in reality it’s a 2.7L GTDI engine.

I saw a lot more cases of such inconsistencies especially while referencing data from Ford fusion sport factory asBuilt vs CyanLabs DB. I carried the test using 4 Ford fusion sports and found these discrepencies for all all them.

Can someone help me understand this better and enlighten me if I am wrong. Thanks in advance

@F150Chief Good day, have you by any chance came across these or similar cases when comparing factory asBuilt vs CyanLabs DB?

Sony system drives everything from the DSP, not the ACM, so this is correct, you do not have front speakers connected to the ACM.

The engine values you are seeing are specific ABS model variations and differences between model years. To include all of the values in these databases would be enormous. Also, if you are comparing to the general ABS listing rather than a specific part number there will be slight differences, which are usually not consequential.

All the time.

The databases posted on this site are directly sourced from Ford, not guesstimates, with the exception of some of the older B and C-series equipment, which the data was no longer available from Ford. To note, Ford Fusions have some of the highest database or asbuilt error rate of most of the Ford vehicles. I don’t know why that is specifically, but likely because they were one of the first CGEA 1.3 vehicles whose database values were carried over from the previous CGEA 1.2 generation.

Keep in mind the Fusion Sport ACM has a DACMC (ANC) which in this case is used to add fake engine noise, built into it just like the Fusion Hybrid/Energi.
The front tweeters are controlled the Sony DSP not the ACM, so the setting of no tweeters in the ACM is correct.

The Cyan DB isn’t perfect, just like ForScan easy buttons aren’t perfect.
The factory value in the ABS is what Ford feels is correct for the firmware/calibration in a 2017 Sport and the value could be entirely different in an 2018.5 Sport.

Thank you so mcuh for the reply. Good to know this info and I believe it will help a lot more Fusion owners. Cheers
