PCM module - block numbers have changed

[npole]

You need to change the value to enable it. It wont turn on by itself.

He changed it.. he means if it will change ON THE WEBSITE (to reflect what he changed on the car).

Maybe I'm not being clear.
I understand that - I've already enabled it earlier today

Edit: npole wrote what I was about to write!

Did the remote rev work as well?

 

[Sainty]

Yes sir! Confirmed remote rev works now by changing:

7E0-162-04 x*xx xxxx xx--
* = second bit from "1" to "2"

 

[npole]

To prove this, I also enabled the continuous gear display, but I did it more recently than the remote rev, and it doesn't reflect the change on the website. So I don't know what's going on here, unless that address is different.

Can you check with your VIN on the website what do you have in this position:

720-12-01

 

[Sainty]

Sure. Although to confuse matters I've also enabled continuous gear display (CGD)

On the website on 20th March it was this and still is today:

  <DATA LABEL="720-12-01">
    <CODE>20C4</CODE>
    <CODE>0000</CODE>
    <CODE>0220</CODE>
  </DATA>

But I did enable CGD on the 20th March IIRC (still enabled today) on the car.

Holy molly I was wrong, because the docs were referring to the USA/UK original settings that is "C" (you have the speed secondary scale enabled.. I assume yours show both Kmh and Mph on the display?). Ours have the "SSS" disabled, so our original value is "8", so for yours to preserve the "SSS enabled" you need to change the bit from "C" to "E", while for us ("SSS disabled") we have to change the bit from "8" to "A".... to be short, guess what, it's "A" on the server!

So this is the proof that the table shown on the website isn't really the stock settings, nor "AsBuilt", not in the meant of what we think. It's the current settings uploaded back to the server that will became the "new" AsBuilt.

I bet yours will be updated as well in a few days (or whatever time it'll need).

 

[Sainty]

Correct I changed C to E!

@roket: would you mind speaking with Livinitup about updating his spreadsheet, with the new info we've figured out in this thread? Specifically relating to the PCM module block numbers changing.

The more I think about this, it does make sense. If a "regular" user changes a setting via the SYNC interface, you'd want those settings to persist through software updates. I'll definitely keep an eye on the data on the website.

Here's an interesting thing.
I downloaded my "As built" file back a few months ago on January 21.
The .ab file is 105,899 bytes in length.

Although I have the recommended lead and FORScan, I never got around to doing anything with it.

For the hell of it, I just downloaded the "As built" file again.
It's now 106,110 bytes.
It has increased by 211 bytes.

Doing a binary compare of both .ab files, I see a sprinkling of changes at byte locations:
02CF4
02D03
02D32
02D33
02D34
02D50
02D51
04CD0
04D0C
050F8
05114
Then the majority of bytes from 06B40 all the way to the end, which is now 19E7F.


Two weeks ago I had the 24C35 (IPC) recall performed at my dealer.

My only explanation is that the 24C35 update is now incorporated into the downloadable revised "As Built".
Or rather, "As It Should Have Been Built"

It would seem stoopid for someone to download the .ab file only to restore it back to the pre-24C35 update, if anyone had to.

Ford adds thing, remove things, they could be unused space (and addresses), so that online table will always change, even if you don't touch anything in your car.
Saving that table with the purpose of having a backup, it's a good way to break the software unless you're absolutely sure that the copy you have comes from the most recent software update (those are just values, but they must match with the current software).
I assume Ford has a real "as out of the factory" table and updated to match the most recent firmware, for each vehicle type, somewhere, so they can "reset" it... but it's not that one we can access from that website.

Does this mean after every update on the car you should make a new back up of the ASbuilt in Forscan? Or is it safe to use the very first back up even when the car updated a couple of times after that?

 

[npole]

You cannot use the very first backup, because in the meantime Ford could have changed something via OTA.
What you should do, is what everyone is doing: do a backup before any change, so if something goes wrong you can revert it back.

In the specific, talking about a real scenario: if you say, what If i want to revert all the modifications I did 6 months ago? Can I just load the Forscan backup of a specific module I did at time? The answer is: you better not, coz you cannot be sure of what happened via OTA in the meantime to all those addresses. If you want to revert all the changes, you better do it manually, one by one, reverting what you did.

I think there is a miscommunication. Maybe I understood wrong or I explained myself wrong.

Before I used Forescan I made a back up of all my modules. These are the original files.

So my question is. Is it safe to use these original files if something goes wrong?
Or is it not safe to use those files because after some updates there can be some changes that can brake your original back ups?
