The ECU (MEDV17) in the M5 is not new and is tunable. The only problem is cracking the RSA signature when writing to the ecu. Seems like only a couple of tuners have managed to do this. I am sure it wont be long before everyone is doing it.

Reading the ecu is easy as is writting but you get the RSA sig wrong and the car wont start.
