Replacing AFM with a Mass Air Flow Meter

["Brian Franchuk" <Brian.Franchuk@xxxxxxxxxxxxxx>]

Hi,

I was wondering if anyone has replaced the air flow meter on their 
car with a mass air flow sensor, particularly on an E28 535i.  I have 
heard that there are performance gains due to the decreased airflow
resistance of the MAF sensor.  How does this work anyway?  I thought 
that a MAF was slower at responding to changes in airflow than 
an AFM.  There must be other inputs besides the MAF sensor that these 
kits are using to fake the AFM signal to the DME.  Are there any 
engine gurus who care to comment on this?

Are these kits worth looking into or are they just a waste of $$$?  Or am
I better off getting a Jim C chip?

Thanks

Brian
