Would'nt the easiest way to increase VE, would be to increase boost?
Based on the timeline BMW had to create this car, and based on the similairities to the output of the IS engine, one possibility is they took the same engine and put it into the 1M. Does it really matter if they didnt do anything else?
I am not sure how cost effective it would be to create some "special" parts to make the engine in the 1M unique. But, I am certain this would not be to their advantage. If they did do this, I would expect the output to be at least marginally better than that seen in the IS engine.
