BMW ISN reading writing capable hardware / software

I have a BMW car with transmission swapped, I need to match ISN with the transmission that is installed. I have icom, iprog, xprog, but all these don’t seem to read or write the ISN.

What hardware & software is able to read & write BMW ISN?

The answer is: you have ABRITES, Yanhua Mini ACDP, BMW EXPLORER, AUTOHEX, VVDI Prog, VVDI BIMtool Pro……. Just so many. It all depends on your budget.

Let’s read some real test results of using Chinese ACDP, VVDI to read BMW ISN.
