NCS Dummy - Taking the expert out of NCS Expert

By [e-mail]

Preface
This message mentions the use of software like BMW NCS Expert. Please don't ask where to get this software, how

to install it or how to get it work. That's beyond the scope of this message and I will not answer these questions.
Keep the thread clean and on-topic. Thanks!
This message describes a method of coding modules. The method is not new, several members in the Diagnostic

Software subforum of this board already practice this method. The only thing that's new is a program, called NCS
Dummy, which may make things a bit easier. The message is written with the BMW E31 in mind, but it applies to

other bimmers as well.

ZCS

The dealer way of recoding the car to, for example, retrofit options is through changing the Central Coding Key
(Zentraler Codierschlüssel - ZCS). I will not explain ZCS coding into detail, but basically the ZCS is a string stored in

the Electronic Body Module (Elektronik Karosseriemodul - EKM) and the Electronic Immobilizer System
(Elektronische Wegfahrsperre - EWS) describing all options of the car. Make no mistake - the ZCS is not used by the
car or its modules. It's only used by the dealer's coding software (SSS/Progman) to quickly identify the car and its

options. The reason it's stored in two modules is redundancy. This allows the dealer to replace every module in the
car, even the EKM or EWS module without loss of the ZCS. The ZCS is not even very detailed. It doesn't list all

individual settings of each module. It's more a descriptive system where the dealer's coding software knows the
exact settings for each module. For example, the BMW E31 Light Control Module (Lampenkontrollmodul - LKM) uses
the same hardware in both Europe (ECE) and the United States Of America (USA), but its behavior is completely
different. The difference is thus in the coding. But with regards to the LKM the ZCS is not more specific than telling
the car is ECE spec or USA spec. However, knowing the region spec the dealer's coding software knows the exact
settings for the LKM module to show either ECE spec or USA spec behavior.
The ZCS coding system was designed with dealers and garages in mind. It allows them to quickly replace modules
with little to no coding knowledge and occasionally retrofit items using a reference list of ZCS changes. The ZCS
coding system was never designed for coding freedom. But that doesn't mean you cannot code the individual
module options. It's just not possible with the SSS/Progman dealer software.

NCS Expert
In comes NCS Expertentool (usually referred to as NCS Expert)... NCS Expert is part of the BMW Ediabas software
suite which also contains programs like INPA - popular and advanced diagnostic software for BMW vehicles. NCS
Expert is the coding part of the Ediabas software suite. NCS Expert was designed for internal use at BMW - in other
words, for people who know exactly what they are doing. Unlike SSS/Progman, NCS Expert provides no help or
guidance. If you don't know what you are doing, you may very rapidly end up with dead modules. Therefore the
program is often labeled as dangerous to use. One of the most powerful features of NCS Expert is the ability to
create Field Keyword and Parameter Keyword trace files (Feld Schlüsselwort - FSW, and Parameter Schlüsselwort -
PSW). Such a FSW/PSW trace file contains a human readable overview of the selected module options. For example,
here's the FSW/PSW trace file fetched from the LKM module of a ECE spec BMW E31 with third brake light using NCS
Expert:

Code:

FEHLER_3.BREMSLEUCHTE

Human readable may be a bit exaggerated, but with proper knowledge of German and a broad imagination for
the used abbreviations, it is possible to understand most if not all options and settings. NCS Expert allows you to

edit the trace file and recode the car with the updated file. Unlike as with the ZCS coding system, this gives total
control over the module coding. Please note that coding the car with an updated trace file does not change the

ZCS! This means that if you make changes through the trace file and later replace a module and have the car
recoded through the ZCS, your changes are lost. Since this normally doesn't happen very often, it's not really an
issue but keep this in mind.
There is however a real problem. The trace file shows the actual configuration of the selected module in your
car, but it doesn't tell what values are possible for each option. Ok, "aktiv" and "nicht_aktiv" are obvious

opposites, but what other value is possible for the "FEHLER_3.BREMSLEUCHTE" value "melden"? Presumably
"nicht_melden", but that's already a guess. And what to do with the "KALTUEBERWACHUNG" value "nsl_li_re"?
Can you guess the other possible value(s)? The trial and error methodology may not be a very good approach

with NCS Expert and the price of the modules. So unless you are lucky and the option you are looking for has
values "aktiv" and "nicht_aktiv", the trace file seems to be a dead end...

NCS Expert knows all possible values. After all, it has to display them or code them. Strolling through the NCS
Expert data files quickly reveals where it stores this information: The "EDIABAS\NCSEXPER\DATEN\E31\" folder

contains a bunch of *.C?? files, one or more for each module (different revisions). These files are like a relational
database and describe all options and values for the module. Mind those are binary files, not simple plain text
files, so the relational information is not that easy to fetch. Furthermore the *.C?? files describe the options and
values with codes instead of the text representation as used in the FSW/PSW trace file. So reference lists are
required to know what option or value goes with each code. These can be found in the "SWTFSW01.DAT" (field
keywords - FSW) and "SWTPSW01.DAT" (parameter keywords - PSW) files - also binary files.

For example, assume you want to know the possible values of "KALTUEBERWACHUNG" (cold monitoring). First
we have to retrieve the code for this field from the "SWTFSW01.DAT" file. Somewhere in it you'll come along
following data:

.. D8 13

01 00

EE 02

4B 41 4C 54 55 45 42 45 52 57 41 43 48 55 4E 47

00

E8 16 ..

•

Previous and next data

•

Start identifier (always 01 00)

•

Hexadecimal code of the field (always two characters long)

•

ASCII representation of the field, in this case "KALTUEBERWACHUNG"

•

End identifier (always 00)

So the code for "KALTUEBERWACHUNG" is "EE 02". Now we can look up this code in the module file "LKM2.C25":

.. 00 17

10 12 00 00 08 01 00 00 01 00

EE 02

00 01 00 01 01 68 00 8F

05 10 00

D7 01

01 00 00 C2

05 10 00

D8 01

01 00

01 CC

10 12 ..

•

Previous and next data

•

Start identifier (differs per module file and sometimes changes even within a single file, but there's
structure in it so it's easily recognizable)

•

The code of the field as found in the "SWTFSW01.DAT" file

•

Start identifier of a value (differs per module file and sometimes changes even within a single file, but
there's structure in it so it's easily recognizable)

•

Hexadecimal code of the value (always two characters long)

So "KALTUEBERWACHUNG" has two values, "D7 01" and "D8 01". That's still pretty much meaningless, so we have
to look up the ASCII descriptions for these value codes from the "SWTPSW01.DAT" file. Somewhere in it you'll come
along following data:

.. 34 09

01 00

D8 01

6E 73 6C 5F 6C 69

00

FA 0C

01 00

D7 01

6E 73 6C 5F 6C 69 5F 72 65

00

B8 14 ..

•

Previous and next data

•

Start identifier (always 01 00)

•

Hexadecimal code of the value

•

ASCII representation of the value, in this case "nsl_li_re" for "D7 01" and "nsl_li" for "D8 01"

•

End identifier (always 00)

We have determined the possible values for "KALTUEBERWACHUNG" to be "nsl_li_re" and "nsl_li". Like I said, you

still need some imagination to understand all abbreviations. In this case, "nsl" stands for Nebelschlussleuchte (rear
fog light), "li" for Links (left) and "re" for Rechts (right). So put in English the cold monitoring has two values, double
rear fog lights and a single rear fog light (in some countries only a single fog light is permitted by law). If you wonder

where the option for no rear fog light is (as is the case in the USA), it's under a different entry
"KALTUEBERWACHUNG_NSL" (cold monitoring rear fog lights) and has for settings "aktiv" (on) and "nicht_aktiv"

(off).

That's all very nice, but the process for determining the possible values is very time consuming and prone to errors.

Since I wanted to know what's going on in all modules, I was facing a huge amount of work. So I decided to
automate the process.

NCS Dummy
I wrote an application that parses the NCS Expert data files and trace files and automatically retrieves all possible

values. Since this literally takes the expert out of NCS Expert, I called the application NCS Dummy:

NCS Dummy is Windows only (sorry no support for Linux and MacOS). The application is written in C# and requires
the Microsoft .NET Framework 3.5 (or later) installed on your computer which is probably already the case.

The current release is version 0.2.0.9 and supports following BMW chassis: E31, E32, E34, E36, E38, E39, E46 and
E86. If anyone requires another chassis, let me know. It's easy to add support for other chassis, but I didn't have any
use for a chassis younger than the E46 - the E85 was added on request.

NCS Dummy has a straightforward user interface, but to avoid confusion here's a short overview of the terminology
used by NCS Dummy:

•

Parameter name: The name of a programmable item, for example "KALTUEBERWACHUNG_NSL". Field
keyword (FSW) in NCS Expert.

•

Parameter value: The value of a parameter name, for example "aktiv". Parameter keyword (PSW) in NCS
Expert.

•

Module parameter: The combination of a parameter name and all its possible values, for example

parameter name "KALTUEBERWACHUNG_NSL" with parameter values "aktiv" and "nicht_aktiv". The
module parameters give an overview of all programmable items in a module and their possible settings.

Very informative to find out what's going on in certain modules.

•

Trace parameter: The same as a module parameter but with indication of which parameter value is selected

on your car. This information is retrieved from the NCS Expert FSW/PSW trace file. Module parameters that
are not in the trace file are filtered out. The trace parameters show the exact coding possibilities of your

own specific module and are useful for creating a manual NCS Expert trace file to recode the module with.

•

Trace file differences: Compares two NCS Expert FSW/PSW trace files and shows only the differences.
Useful to quickly find coding differences between two different vehicles.

Just to clarify: NCS Dummy only parses NCS Expert data files and trace files. It doesn't actually use NCS Expert, it

doesn't connect to the car and it doesn't make changes to any file. In other words, it's safe to use. If you are
interested in finding out what coding functionality for example the EKM module offers, you can safely export its

module parameters to a human readable text file with NCS Dummy. NCS Dummy only requires the NCS Expert data
files to build the relations between parameter names and values. You don't even have to run NCS Expert to create a
FSW/PSW trace file. Of course, if you wish to code modules, you'll have to use NCS Expert.

There are three practical scenarios of use for NCS Dummy:

•

Module Parameters: Find out what coding functionality a module offers. NCS Dummy shows all parameter
names and their possible values.

•

Trace File Differences: Compare two NCS Expert FSW/PSW trace files to see the differences (requires NCS
Expert to read the trace files from the car).

•

Trace Parameters: Same as the module parameters, but this time for the specific module in your car
(requires NCS Expert to read the trace file from the car). You get a nice overview of the currently set values
and the other possible values. This makes updating the trace file to recode the module with NCS Expert a
breeze.

Module parameters

Start NCS Dummy, if necessary change the path to the NCS Expert installation folder, select the chassis (E31) and
select the module you wish to view (for example "LKM2.C25" for the LKM module). Then click the "Export Module
Parameters" button to save the information to a text file (NCS Dummy doesn't contain a viewer). Open the exported
text file in a plain text editor - preferably with monospaced font - to see it contents. Here's the example output of
the LKM module:

With only 8 parameters the LKM module isn't very impressive of course. The General Module (GMII.C25) or the
EKM (EKM.C?? - there are different revisions of this module) contain more parameters, often with not just

"aktiv" and "nicht_aktiv" values which gives a much better impression of the program's possibilities.
The real power of the program becomes apparant on cars with lots of programmable modules and parameters
like the E36 and especially starting from the E38 and up. The E31 8 Series are somewhat like an electronic
dinosaur. There's only a limited amount of programmable modules and those usually contain only a limited set
of parameters. Those who had hoped for a massive amount of hidden coding functionality in the E31 will be
disappointed. For example, some had hoped the E31 LKM could be recoded to disable the hot/cold monitoring
on certain lights to install xenon or LED lights without the need for the stupid resistors to keep the LKM from
reporting lamp failures. It doesn't offer all that. The E38 LKM module for example can have hot and/or cold
monitoring enabled or disabled for each individual light in the car. Very impressive. Realistically put, the use of
NCS Dummy for the E31 is rather limited. It's great to learn more about what's going on in certain modules, but
for recoding only a handfull of options will prove to be interesting - mostly for retrofitters. One thing that comes
to mind is changing a USA spec LKM to ECE spec behaviour, without the need of installing rear fog lights as is
necessary when changing the region through the ZCS.

Trace File Differences

Start NCS Dummy and load two NCS Expert FSW/PSW trace files (reading a trace file with NCS Expert is
discussed further down). Click the "Export Trace File Differences" button to save the differences to a text file.
This is useful if you want to compare the coding differences between two different vehicles. For example, if you
want to figure out what differences the ZCS region change really does. Below is the example output for the
General Module of my E31 and one of Reinhard's cars. As you can see, the only difference is the headlight
washer system that is not installed on Reinhard's car (and hence also disabled in the module's coding).

The asterisks show what setting is enabled in your car. Assume you want to enable the door lock heating

("TUERSCHLOSSHEIZUNG"), make a copy of the original NCS Expert FSW/PSW trace file "FSW_PSW.TRC" in the
"EDIABAS\NCSEXPER\WORK\" folder and rename it to "FSW_PSW.MAN". You may have to remove a previous

version of this file first. Open the "FSW_PSW.MAN" file in a plain text editor and change the value of
"TUERSCHLOSSHEIZUNG" from "nicht_aktiv" to "aktiv". Save the file and you are ready to code the module with the
changes (coding with NCS Expert is explained further down). Please note that the door lock heating will only work if

your door handle mechanism has the door lock heating coil installed and the plug inserted.

Reading FSW/PSW trace files with NCS Expert

Despite people's claims of how dangerous NCS Expert is, reading FSW/PSW trace files from a car is perfectly safe as
long as you keep your head at the job. NCS Expert's default setting is to code, which we definitely don't want (at this
point), but once the job type is changed to reading the program is harmless. You don't need to take special
precautions for the car. Reading trace files takes just seconds, so there's absolutely no need for an external power
supply. Low battery voltages cannot cause damage, but may of course drop the connection so you are unable to
complete the trace file reading. So make sure your batteries are ok and properly charged.

Before you can start reading FSW/PSW trace files with NCS Expert you need a good profile. By default NCS Expert
comes with the "Expertenmodus" profile ("FZG2.PFL"), which despite the name is not that expert at all. You can
either use the "Fisterprofile" ("GOODFIST.PFL") from the founder of

bmwecu.org

, or my profile:

Unpack the zip archive and put the "REVTOR.PFL" profile file in the "EDIABAS\NCSEXPER\PFL\" folder.

Go to the "EDIABAS\NCSEXPER\WORK\" folder and (if not already existing) create a new empty text file called
"FSW_PSW.MAN".

Now connect your diagnostic interface to the car and turn the ignition to I. Test the connection with for example
INPA. Don't forget to close INPA before using NCS Expert. The interface throws errors when multiple applications try
to get access to it.

1. Once the profile is in the PFL folder and the diagnostic link ok, launch NCS Expert. At this moment no profile

is loaded, so the screen is quite empty.

2. From the "File" menu, choose "Load Profil".
3. In the "Choose profile" popup window, select "Fisterprofile" or "Revtor's NCS Expert Profile" and click

"OK". Nothing much happens, but you'll notice some of the buttons on the bottom now have labels.

4. Click the "VIN/ZCS/FA" button (F1). The button labels change once again.
5. Click the "ZCS/FA f. ECU" button (F3).
6. In the "Choose CHASSIS" popup window, select "E31" and click "OK".
7. In the "Choose ECU" popup window, select "EKM" and click "OK".
8. After a short moment, the top groupbox should now show information regarding your car.
9. Click the "Back" button (F6). The middle groupbox now shows the available modules and default job name.

The default is "SG_CODIEREN" which we definitely don't want, so pay attention what buttons you press
right now!

10. Click the "Process ECU" button (F4).
11. In the "Choose ECU" popup window, select the desired module and click "OK". If you want to read all

modules, you'll have to work module by module. Select for example the General Module ("GMII").

12. A popup window displaying the *.C??, *.IPO and *.PRG files for the chosen module is shown. Write these

filenames down as you may need it for NCS Dummy. Click "OK".

13. Click the "Change job" button (F2). If "JOBNAME" in the middle groupbox already reads

"CODIERDATEN_LESEN" you can skip the following steps and jump to 16.

14. In the "Choose job" popup window, select "CODIERDATEN_LESEN" and click "OK". The default job action is

now reading instead of coding. Note that NCS Expert will still say "get coded" in the middle groupbox and

during the read operation it says it's coding... but it will not. "CODIERDATEN_LESEN" is a safe read-only
operation.

15. Confirm "JOBNAME" in the middle groupbox says "CODIERDATEN_LESEN".
16. Click the "Execute job" button (F3). The process takes only a few seconds. As said, NCS Expert may indicate

it's coding but it's actually only reading.

Head over to the "EDIABAS\NCSEXPER\WORK\" folder. In it is now a file that interest us: "FSW_PSW.TRC". The first
is the human readable FSW/PSW trace file. Each time you read a module with NCS Expert this file is overwritten, so

you must move or rename it (no need to copy - if the original file is missing, NCS Expert will write a new one). For
example: "E31.GMII.FSW_PSW.TRC".

You have finished creating a FSW/PSW trace file for the GMII module.

If you want to read a FSW/PSW trace file from another module, head back to NCS Expert, click the "Change ECU"
button (F1) and repeat the steps starting from 11, but with a different module.

When finished, simply close NCS Expert.

You can open the "FSW_PSW.TRC" file (or whatever you renamed it to) in a plain text editor. The "FSW_PSW.TRC"
files are also the files used by NCS Dummy to create trace parameters or trace file differences.

Coding modules from an updated FSW/PSW trace file with NCS Expert

First of all make sure you have a good NCS Expert profile. Read the previous chapter for more information on
profiles.

Where little could go wrong with reading, coding is a different story. You don't want the battery voltage get too low
during coding as this may render the module dead. Luckily old bimmers like the E31 don't take long to code - just
seconds per module. So you don't need any special precautions if your batteries are good and properly charged.
Nevertheless it's recommended to attach a small 13.8 V power supply to keep the voltage well over 13 V. A simple
battery charger with power supply mode functionality and a current output of 5 A or better should be sufficient.
Note that newer bimmers may take a lot longer to code, with a much higher current draw. BMW recommends
power supplies that can deliver over 40 A for newer cars.

Make a copy of the FSW/PSW trace file you wish to make changes to. Open the copy in a plain text editor, make the
changes and save the file. Rename the copy to "FSW_PSW.MAN" and put it in the "EDIABAS\NCSEXPER\WORK\"
folder overwriting a previous version (if existing).

Connect your diagnostic interface to the car and turn the ignition to I. Test the connection with for example INPA.
Don't forget to close INPA before using NCS Expert. The interface throws errors when multiple applications try to get
access to it.

1. Launch NCS Expert. At this moment no profile is loaded, so the screen is quite empty.
2. From the "File" menu, choose "Load Profil".
3. In the "Choose profile" popup window, select "Fisterprofile" or "Revtor's NCS Expert Profile" and click

"OK". Nothing much happens, but you'll notice some of the buttons on the bottom now have labels.

4. Click the "VIN/ZCS/FA" button (F1). The button labels change once again.
5. Click the "ZCS/FA f. ECU" button (F3).
6. In the "Choose CHASSIS" popup window, select "E31" and click "OK".
7. In the "Choose ECU" popup window, select "EKM" and click "OK".
8. After a short moment, the top groupbox should now show information regarding your car.
9. Click the "Back" button (F6). The middle groupbox now shows the available modules and default job name.
10. Click the "Process ECU" button (F4).
11. In the "Choose ECU" popup window, select the desired module and click "OK". Make sure the updated

"FSW_PSW.MAN" trace file is for the same module.

12. A popup window displaying the *.C??, *.IPO and *.PRG files for the chosen module is shown. Click "OK".
13. Click the "Change job" button (F2). If "JOBNAME" in the middle groupbox already reads "SG_CODIEREN"

you can skip the following steps and jump to 16.

14. In the "Choose job" popup window, select "SG_CODIEREN" and click "OK". The default job action is now

coding.

15. Confirm "JOBNAME" in the middle groupbox says "SG_CODIEREN".
16. Click the "Execute job" button (F3). The process takes only a few seconds on older cars like the E31.

After NCS Expert has finished coding, close the application and turn the ignition back to off. That's all there is to it.
The car has been coded.

As stated before, this coding method does not change the ZCS. In other words, if you ever recode the car using the
ZCS all your changes will be lost. So if you are happy with the new coding, keep a backup of the "FSW_PSW.MAN"

file - just in case. I also recommend keeping a backup of the original unchanged "FSW_PSW.TRC" file.

If you are interested in reading FSW/PSW trace files...

If you consider creating FSW/PSW trace files of your own car(s), I'd appreciate it if you'd send them to me. Don't
worry, the trace files contain no information that can identify your car (no VIN). If you are uncertain, just open them
with a plain text editor. The reason I'm asking is to get a better picture of the differences between the various E31

models and regions. At this moment I'm particularly interested in trace files from USA spec E31 and early E31 (say
1992 and older).

When you do send trace files to me, please specify the VIN (or if you prefer to keep your car anonymous, the exact
model, month/year of production and ECE/USA/.. spec). Also include the *.C?? filename as reported by NCS Expert
for each module (for example "EKM.C25").

You may even send trace files from other non E31 bimmers. Thanks!

Q&A

Does the method described in this message allow to couple a used EKM to another used instrument cluster? No.
While the EKM module parameters hint at this ("GEBRAUCHTBIT_KMB", "GEBRAUCHTBIT_EKM",
"GEBRAUCHTBIT_KMB_KOMPL", and "GEBRAUCHTBIT_EKM_KOMPL") I don't think it's possible to change this
through NCS Expert. At least not using the method described here.

Does the method described in this message allow to chiptune the engine? No. The Bosch and Siemens engine
managements are a completely different territory.

Does the method described in this message allow to enable the functionality to automatically roll-up the windows
with the radio frequency remote (as was possible with the early infrared remotes)? No. Even though the General
Module FSW/PSW trace file hints at it with "KOMFORTSCHLIESSUNG" (comfort closing) which is set to "nicht_aktiv"
(off), this parameter seems to be completely unrelated (believe me, I tried). In fact, the real setting for this
functionality is in the radio system (the radio frequency remote receiver, not the head unit obviously). Using INPA
one can actually view the "Luxury opening" and "Luxury closing" settings under "E31" --> "Body" --> "Remote
controls" --> "Coding". The bad thing is this module is not supported by NCS Expert. The fact that it's listed under
"Coding" suggests it can be changed through software, but I'm not sure what software can do this. Another option
listed on the INPA coding page for that module is "Panic Mode". This one can be enabled or disabled through
SSS/Progman ("3 ZCS/FA CODING" --> "1 E31 Series" --> "4 Conversion" -- > "6 FKS" --> "1 Panic Mode"),
encouraging the idea the luxury opening/closing can also be changed similarly. However, luxury opening/closing is
not shown in SSS/Progman... To get back to the original question, if the module is not shown in NCS Expert, NCS
Dummy and the instructions above are of very little use.

Afterword

Please note that while I'm quite confident NCS Dummy produces reliable output, the application comes without any
warranty. If you ruin a module with NCS Expert after using information retrieved by NCS Dummy, don't look at me...

Due to the scant coding functionality of the modules in the BMW E31, the use of NCS Dummy and the instructions

given above may be rather limited. Nevertheless it shows a good method of giving USA spec cars ECE spec headlight
behavior without the need of adding rear fog lights. It's not until the E36 and especially the E38, NCS Expert coding
offers a lot of possibilities. Of course NCS Dummy can be used on these newer bimmers.
