Few months ago we never even thought flashing over OBDII was going to be possible.
Nevertheless not sure if these OEM tunes are just reverse engineered or actual BMW tunes.

They are reverse engineered. They compare the changes a stock CS map has to a non-zcp map and apply those same changes to the tables on your stock non-zcp file and the end result is a CS tune. That's how CS maps have been installed on a 6MT car when a CS never came with a 6MT.
The end result is the same now given that you are able to unlock and flash via OBDII.
Just a month ago it was a different story when you couldn't unlock via OBDII. Some people wanted OEM BMW ZCP tunes, but didn't want to have their DME pulled out and opened to get unlocked. So their only option was by paying the insane premium to get an authentic FSC code. But now since you can unlock via OBDII, reverse engineering the map and flashing via OBD achieves the same result with a fraction of the cost. |
