Dave Morrills O2 meter?

[Rex Weatherford]

I was looking at the schematic for Dave's meter and had a few questions.

What is the LM3914? 

It says I can buy a meter like this from JC whitney for $20?  Is that
true?

How are these used...  I know that my ECM looks for values between .100v
and 1.1v.  And that my EGO sensor has to warm up before this means
anything.  Correct?

My car is a Beretta GTZ with Olds Quad4.  Will I be able to tell when
the car is reach and lean from this?  I'd assume so.


Thanks...

I'm sure I'll have more questions.
