Transit Custom BCM D or Full flash

[expertinnotalot]

If I am upgrading a transit custom BCM do I need to swap D flash and full flash or would D flash suffice as I suspect D flash is what holds the vehicle configuration data. Please correct me if I am wrong

No one knows ? I have been using this forum for over 5 years and find it hard to believe no one knows

Thank you, I already have the files, i was just wondering if I have to transfer both the d flash and the p flash to the donor module :-)
