Good starting point!

The output ranges from 0V to 2.0V or so.
A good plan is to purchase CyberDyne's A/F gauge, its the type with 10
LEDS
in red/amber/green to (sorta) show A/F ratio.  The benefit of
CyberDyne's
guage over some of the others (MSD; Accell; etc) is the low cost. 
CyderDyne's
is around $30, while MSD's is $130 or so.  The other ones claim wide
ratio
A/F monitoring, but with the standard sensor they include (no ERGO)
accurate
wide range just isn't possible.  CyberDyne's is also nicer (in my
opinion)
because its a 2 1/16" round gauge, instead of the square ones from MSD. 
This
fit my guage panel much nicer; right next to all my VDO guages.
I use mine on my FI Volkswagon and FI Fiat X1/9; tied it in to the stock 
(1 wire) sensor.

You can purchase CyberDyne's guage from Jegg's or Summit.  
Summit Racing is at 330-630-3030, Gauge P/N:CYB-7009
(They also sell a standard Bosche heated (3 wire) sensor to
match; CYB-8941; $52.95)
