well bmw has stopped supporting BMW M laptimer already.. sad because its telemetry was 10hz and so much better than RaceChronoPro/TrackAddict/Harry's Laptimer with OBD-2 (Kiwi3/OBDLink CX/OBDLink MX+)
i even wrote a program to convert the .mpower format to CSV to import directly into Race Render 3...

i asked them if its still possible to get the .mpower data without the iOS app, no response so far, but if that is the case, the M Laptimer iDrive App is basically a big stupid stopwatch on iDrive screen now.. LOL
