[MaC-N54-E82]

Loaded the beta version of 4.01 (stage 1 / sport / stock throttle) and my 135i instantly gave me a service engine soon error message and the car produced a tremendous amount of white smoke at start-up and idle. Reloaded version 3.01 and both the error message and smoke disappeared. Looks like COBB still has a few bugs to work out on the Beta. I will stick with version 3.01 until 4.01 comes out of Beta.
