Mini guide on how to extract your DE (NBT) or 1B (CIC) file, generate the FSC code.
Prequisites:ESYSENET CablePSDZData Lite (lite version is fine for FDL coding, you only need the full package if you want to flash ECUs)Token (not required to reach FSC Extended)CIC PREMIUM Maps or NBT NEXT Maps If you are generating maps for NEXT, then you need to follow the guide for DEIf you are generating maps for MOVE, MOTION or PREMIUM, then you need to followthe guide for 1B
Extracting the DE or 1B file:Fire up EÂsys make sure your connected to the F20 (not F20_Direct) via your VIN and then inthe left-hand vertical menu select FSC Extended.
For NBT (DE File):In the Parameter section enter:1. Diagnostic Address (hex) = 0x632. Click on the Identify button and the Base variant HU_NBTwill be populated3. Application ID for NBT= 0xDE4. Upgrade Index = 0x1
For CIC (1B File):In the Parameter section enter:1. Diagnostic Address (hex) = 0x632. Click on the Identify button and the Base variant HU_CICwill be populated3. Application ID for NBT= 0x1B4. Upgrade Index = 0x1In the Action section:5. Select Store FSC and move from left to the right6. Click on the Read button7. Click Save and name the file in the following formatXXXXXXX.fsc where XXXXXXX islast seven letters/numbers of your VIN or your donor NBT vin if you have retrofitted the NBT.8. [Optional] You can now disconnect eÂSys from your car as the next stages can beperformed offline.
Getting the Code Generation Software:Unzip the directory attached. The directory can be placed/run from anywhere.
Generating the FSC code using the BMW_CIC_NBT_FSC_Generator for NBT:If you are generating NBT, copy fsc.exe in the NBT_FSC directory to the tools directory.
1. Place your XXXXXXX.fsc into your tools directory (same location as the Base64.exe)2. Open a command prompt (DOS Screen) and go to the tools directory3. Type "Base64 XXXXXXX.FSC XXXXXXX_000DE001.FSC" and press enter4. Open BMWÂFSCÂNBTÂGenerator.exe5. Click "Browse" and select the XXXXXXX_000DE001.FSC file you generated in step 3, itshould be in your tools directory.6. Choose your map product from the list (For me it was "Road Map EUROPE NEXT 2015Â1)7. Click "Generate"

Click "Generate"
Preparing the USB stick:Takes about 45 mins to upload the Maps to your car; make sure you enter the codein CAPITALS, it has been said that you should have the car on/running during this period. Butfor me just pressing the Start button once was enough. Once the update is done, you will geta success message, wait a few minutes then turn the car on/off and then the version numberwill reflect the new map.
NBTUSB stick needs to be FAT32 (32GB is enough) when you extract the map data to the stickMake sure you extract the folders to the USB root. The folders will be like:1 (directory)2 (directory)3 (directory)4 (directory)config.nfmNBT_ECE_101141.3.111.pkgNBT_ECE_101141.3.111.pkg.sig
CICFor the PREMIUM (CIC) maps you will have three directories:USB1 (directory)USB2 (directory)USB3 (directory)Copy the entire contents of USB1 to the root of the USB stick, should only be the following:config.nfmpkgdb (directory)Once uploaded to the car, the car will ask for USB2. Delete both the config.fm and pkgdbfrom the root and repeat the above with USB2....and then again with USB3
Notes:
What happens when NEXT/Premium comes out? You just need to edit the Lookup.xml file with the new map details, just look at the previous entries, its follows a sequence.
Backup your FSC file!!!
Save your XXXXXXX_000DE001.FSC file, you can now just refer to this file and generate as and when the new maps come along. If you lose this file you will need to do the extraction steps again.
