Hello,

I try to learn how IMMO4-C with Challenge ID works and do some tests with reading, changing, writing EEPROM dump.

I have one original immobilizer that work in the car with correct immodata and one other immobilizer that don’t work (is use this for testing)

So my question is:
Can I put the test immobilizer in the car for testing result without any future problems? If I change back to the original one would everything works fine with iMMO? Or the car (e.g. ECU) blockes when a wrong immobilizer was sometimes built in?

I won’t destroy my working car :-D.

Perhaps someone can tell me what’s happen when changing sometimes between orig and test cluster.
