Lean cruise

[rr]

As they say, "The results are in."

I have the final numbers on fuel mileage from the Pow-wow
trip, along with the baseline. 3.1L v6, RWD, MPFI.

About a year after I got this car I took a trip to Florida &
back (Pa). I can't find my notes (I know) however, the mpg
was almost what the sticker showed: 27 MPG on the highway.

The trip out to visit Doc and friends, and back netted 29.8
mpg. That's a 9.4% increase in fuel economy. Not bad, eh?

This is using a lookup tbl based on MAP (should be VAC),
that varies the AFR from a lean of 16.6 through 15.4 at the
higher loads. Also added just a couple of degrees of timing
with this.
