I am curious ... very curious .... I know the BMWs run lean, and want to improve on that.

See my post here

The wunderlich controller gives you more options over the rev-range. The other one just fools the injection by use of a temperature related resistance, making it think it is about 10 degrees celsius colder en thus it will richen the mixture.

If you take away the cat. or put a 'sport' exhaust on the MM you will have to take measures for it not running to lean.
