Some useful information may be found here:
Some info Voltaire may not have: you can run it with an inductive trigger like Voltaire or a hall sensor. Means AFAIK that you could use the BMW unit (if you can freeze the mechanical advance).
Some guys over here use a complete can unit from a Volkswagen which has no advance.
In case you are interested I would check these information. As I prefer another solution I don't pay too much attention to the threads about that topic so I'm not a 100% sure.
Alternatively the german reseller here offers the complete package with a trigger mounted on the alternator.
Ignitech does not offer special BMW parts.
