All
i am asking for a few with 2025s ST to do a little forscan test and evaluation
it is in the area of (fake engine noise and Active noise cancellation) but in the 2025s its named propulsion noise??
anyway,
if you can read this and then post back your AS built codes under the respective ACM and DSP
as well as make the below changes and provide feedback on whether it worked or not, and which radio system you have, 12 speaker, 14 etc.
AND AS ALWAYS, BACK UP YOU AS BUILT FILES prior to making changes and even write them down so you can revert as needed.
all changes are made at your own risk.
you can download your AS BUILT files at https://www.fordserviceinfo.com/ , you will need to use your ford owner login or create one if you do not have one presently
a hint on the as built files is to PRINT THE PAGE TO A PDF, or similiar, as adobe will not open the download sometimes
VINS must entered in CAPS
we all can benefit, and I or nightshade will add them to the common page on the 25 explorer spreadsheet



Test VIN has this in the as built below

AS BUILT 727-01-02 0000 9204 00C7 2 =disabled • ANC Disabled • ESEPS Enabled • MSS Disabled
CHANGES 727-01-02 xxxx x*xx xx-- select 4 =CC Disabled • ANC Enabled • ESEPS Disabled • MSS Disabled


DSP 783

as built test unit 783-01-01 0492 0 = R Reserved • APIM Do not log missing APIM messages • R Reserved • ANCPS ANC not present

783-01-01 *xxx xx-- change the * to 3 =R Reserved • APIM Do not log missing APIM messages • R Reserved • ANCPS ANC present

i am hoping this turns off the propulsion noise, but leaves the Active noise cancellation enabled


thank you
edited 17 oct 24 to correct the dsp code to 783-01-01

My as-built matches those you posted.

727-01-02 0000 9204 00C7
783-01-01 5801 00E5
783-03-01 0492

Did you mean to post 783-03-01? Or should both of those have been 783-01-01? That key seems to match your description better.

If so, you are saying to change the stock value of 5 to a 2?

5 = R Reserved • APIM Log Missing APIM messages • R Reserved • ANCPS ANC present

2 = R Reserved • APIM Do not log missing APIM messages • R Reserved • ANCPS ANC not present

Also, what is the most objective way to measure whether the change was successful? Does the sound come out of all speakers? Maybe putting a microphone right up against a speaker for before/after runs.

yes, 783-01-01 vice 03 -01 thanks for catching it, after a while the numbers run together

for me the best way to notice of sound changed is with a sound meter app that shows Decibels
its not super scientific but the loss of certain noise is noticeable

thank you for your diligence

Can you explain what this change does?

783-01-01 0492 (0 = R Reserved • APIM Do not log missing APIM messages • R Reserved • ANCPS ANC not present)
783-01-01 2492 (2 = R Reserved • APIM Do not log missing APIM messages • R Reserved • ANCPS ANC not present)

Both descriptions are the same.

Yes my blind ass typed a 2
thats what get juggling to many items at a time
i need a few weeks off i think
i apologize , good thing it was not a nuclear code :eek:
It should be a 3 if acm is turned off

you turned off the propulsion in the ACM
3 to keep active noise control on. But i have no data to support that is factually what happens.
until some people do it and test
there is an issue with b and o sound processor if you turn off engine noise it cancels the active noise control
what makes it even more AFU, is i have looked at 6 as built files from 6 Vins and 4 are different in the dsp settings
ford did some as built file changes i assume after a certain build date, but i have not determined why ??

me not having a 25 makes it very difficult to get accurate results.
my side kick nightshade is due a 25 any day and hopefully he can be a test guy over and over
