	It's 5 (or actually ~4.9)  at WOT.  This goes for the MAF and
AFM.  What differs are the idle outputs and the voltage curve to WOT.
	
	I'll post full details here once I get an operational version.
As I'm sure there are many system that could benefit from this kind of
thing.
	
	Never really considered MAP.  I'm not planning on FI atm. and
many others on the e30zone (or which I'm a member) have done MAF
conversions costing upward of 800+ , I was sure that there was a cheaper
way.  I'm expecting my conversion to cost under 100.  50 or so for the
MAF, and under 50 for the PIC.
	
	For my application I can't think of a reason to go for MAP.
	
	Do you guys have any comments as to the pros and cons of MAP/MAF
?  For naturally aspirated.


MAP and MAF aren't interchangeable like that.  MAP by itself doesn't
give enough information to do fueling, it has to be combined with RPM at
least in order to calculate airflow.  MAF gives airflow directly and so
already has the RPM term in it.

Is AFM the flapper door flow meter?
