DIY BMW E46 coding with NCS Expert

This is a little NCS expert software tutorial on coding BMW E46. Aim to help if anyone has any questions and of course can carry out any coding changes.

 

 

Equipment:

NCS expert coding software

A hardware cable (BMW INPA K+DCAN cable/BMW ICOM etc)

 

First we will need to set up a coding profile within NCS expert.

1) Open NCS Expert.

2) Open up the ‘Expertmode’ profile.

3) Save as a new profile (give it a name, like the godfather or something powerful sounding).

4) Load the ‘godfather’ profile.

5) Edit it (file –> edit. Password is repxet).

6) Make sure under button ‘Individualisierung’ all options are crossed.

7) Make sure under button ‘FSW/PSW’, that ‘from CVT’ is chosen, and that the bottom two boxes are crossed.

Finally, press ‘consistence check’ and check it works.

9) Then press okay

You should now have a coding profile!

You read using the ‘Expertmode’ profile, and code using the ‘Godfather’ profile. (Ignore the other profile)

Once NCS is open Choose File from the top menu

Select Load Profile

Choose Expertmode profile.

Then Press F1 or choose VIN/ZCS/FA

Now press F3 or choose ZCS/FA f. Ecu

Select the model carE46

Chose the Module in which to read the ZCS/FA, In this case we select the top one. If that one doesn’t work for you, choose the next one below, etc until you find one that works. Bear in mind that the bottom two will not let you read all options. If you find that you cannot read the top one, then you may have a key programming issue (i.e. previous owner losing a key, and BMW not programming the new one properly), or that your car has had an ECU changed that doesn’t match the car’s VIN.

Upon seeing the below screen with the FG and FA Values displayed simply hit F6 or Back.

Click Process ECU

You will now get a list of installed modules that were identified when communication with the chosen "main” module as before.

Select the Module/ECU you would like to work with, In this case the GM5

Now you can choose READ ECU to perform a read out of the module.

You will get a NETTODAT.TRC file popup simply close it.

Navigate to the Work folder which resides in your NCSEXPER directory. You will locate a file FSW_PSW.TRC

This file was created when READ ECU was performed and contains the coding values for that module.

Remember this file is overwritten each time a read out of a module is performed. It would be advised to make a back up of this file in the event you need to restore coding settings. (Just right click and copy and paste the whole file on your desktop or somewhere you can remember in case there is any mistake, if you have this copy of original you can fix.)

NOTE:!!! AT THIS POINT, you have not done any programming, you have simplyreadthe module. You should make a copy as above, but at this point you can exit NCS & disconnect from your car…. and take your time to read this copy of the trc file, and decide what you want to change… and come back to it later. When you go to the next steps, this tells you how to actually change things in your car. If you make some mistake, use your original as the .man file to change them back…

THE NEXT STEPS ARE FOR ACTUALLY CODING TO THE CAR:

Once you have made a backup, Right click and rename the file to FSW_PSW.MAN

*Once you have a .man file and are ready to code your changes to the car, you can do this step, or if you prefer, DELETE the .man file in work folder, and start over again from top.. Just make sure there is only one .man folder in work and that this includes the coding you want to change in the car.

Yes to make the change.

Now right click and choose Open With…

Select Notepad and tick always use the selected program to open this kind of file. Then Press OK.

Now we can make changes to the coding file.

Car Key memory:

A heres a guide to car/key profile and button in NCS:

The typical sequence for the customization is as follows:

1. Button Select the "individualization”.

-> The operating side, the potential for the individualization ZCS FSWs customizable displays the selectable PSWs. The intended state of PSWs is marked with a prefix ‘S’.

2. Button Select the "READ”.

-> The actual state of the customizable PSWs FSWs is determined and with a leading ‘I’ marked.

3. Button Select the "TAKE OVER”.

-> The currently selected PSW becomes the new target value for the vehicle in the list of gänderten PSWs.

4. Button select "BROADCAST”.

-> The controllers of the vehicle in which PSWs have changed are encoded. Amended by promoting PSWs the list of changed PSWs.

Anyway, back to coding. Once you’ve made the changes you want, save the file.

Choose file and click save. (common mistakes here is saving the .man folder incorrectly as a .txt file, make sure when saving you have a .man file, not .man.txt! will not work. If problem saving, choose instead "save as” and where box says file type. Choose "all files” not text.

Now click Load Profile

Choose the Godfather Profile

Now press Process ECU so we can tell NCS Expert what module we would like to code to.

Choose the Module and press ok. (Make sure this is same modules you read from!)

Press Ok.

Now we are ready to code the PSW_FSW.man to our GM5 unit. Make sure the JOBNAME is set to SG_CODIEREN.

If it is not simply click ‘job’ and choose SG_CODIEREN. Make sure you’re using the module you previously read from: in this case the GM5 (Or the unit you will be working with)

Hit Execute Job to perform coding.

Underneath GM5 a status will appear initially saying CODING ACTIV and then CODING ENDED. Depending on size of file and can be a few seconds or a few minutes… very important not to disturb car or computer here… if battery dies, coding incomplete… you will have to use your back up… not very common, but it’s always possible! Always back up original!!

Once this is completed you may power off the car wait 10 seconds and repower up to see whether your coding changes have taken.
