Strange... the Bimmerworld one, had an option for MAF a few weeks ago, now it's gone.
It said "not recommended" but they had one that didn't require Alpha-N.
(I am not an alpha-n fan, due to it's lacking properties over a MAF system).

Just like this one

I truly wonder what the power difference is, since having a MAF is totally preferable for a street driven car.
