There are several posts confirming these changes under F80 sub-forum.

That being said, I'm sure BMW has made some changes to their CS DME over the time as well. Do you guys just pick a certain I-Step for CS and make it available on your platform? ... or do you update your OEM maps as BMW introduces updates through newer I-Step versions? Ideally, I would like to run the latest CS DME software by BMW. How do I make sure of this?
You flash this via ESYS if it matches your car.

BM3 does not over-ride the ROM version of your car that you activated with. In order to do as you described you must first update your car to the latest DME software for your variant of the S55. Once that's done you can load the latest CS map from BM3 which is for your ROM version. Or I can give you one to flash with.

PM me if you need remote assistance on this
