We have a couple of different tools to flash the old Siemens ECU's for the first gen N63 turbo cars, unfortunately for some reason they will not read out the ECU via obd2 and when I ask the tool manufacturers, they don't seem to want to fix it, not sure why to be honest. The X5m, and the x5 50i we have tuned with great success but the 2011 550 and 750's we have tried don't seem to cooperate.
We have tunes for the naturally aspirated cars with the Bosch Me9 ECU, those are good tunes but obviously don't gain the kind of power we are seeing on the turbo applications.
