In the previous article, we announced that FormulaFlash ECU Programmer will add BMW ISN/VIN modification feature on Nov. 12th, 2024 and shared the tips on how to receive a 6-month free license for this feature (click here to review). Today, we’ll guide you through using this new function with FormulaFlash.

For example: BMW 7 Series 2008- 2015 MSD85.4

Connect FormulaFlash and computer, and supply power to the device as well

Run FormulaFlash software

Input MSD85 in the search box to quickly find the corresponding car model

Follow the diagram to connect FormulaFlash and BMW MSD85 DME correctly

After that, click “Connection” and wait the process is complete

Then click “VIN/ISN/IMMOFF”

It will read the EEPORM and Flash data quickly, and show the PSW, VIN and ISN info.

Modify ISN:

Input the new ISN and click “Modify”

For example, we modify the last 2 digits “EA” to “12”, and then click “Modify”

It will show “Success” once the ISN is modified successfully.

Generate:

Click “Generate” and confirm to write the data directly to ECU

Wait a while, it will write the data into the ECU successfully.

Alright! That’s the whole process to modify BMW VIN/ISN by FormulaFlash ECU and TCU Chip Tuning Tool, very easy and fast!
