Speaking of V8s...

Just a simple graph of idle speed vs time for the first few minutes after a 
cold start might be a fun high school science project.

Is the idle speed of a modern warm engine locked to the CPU's crystal or is 
there a feedback loop setting some pollution or mileage parameter?

In the old days (pre computer), there was some thermal input to the idle 
speed.  I assume it was a bimetalic element.
