I bought a megasquirt so I could try to tune lean burn in, but thats not the exciting revelation. I bought an extra computer so I could de-solder the plug off to make an adapter. This way I could plug the megasquirt in and not have to worry about driving the car while I try to get a good tune on it. I found a computer for a 94 escort automatic for $10 on ebay. After it sat on my desk for a few days I remembered the Lean on Cruise (LoC) that escorts supposedly had. So I decided to just swap computers and go for a drive. At first I didn't notice anything and the wideband didn't show any lean cruising. Eventually though the gauge stayed at ~18.x:1 for a little bit. I think I figured it out. I just go faster than I want to go (I was only able to get it to work above 53 mph) then dfco'd and gave it a little bit of gas. I was able to maintain the ~18.5:1 for about 6 miles before I had to turn. I was getting roughly the same mpg per the instant reading at 60 mph as I was getting at 40-45 mph on the original computer.

There are several things I need to check though. Does the MPGuino need to be recalibrated now that I have a different computer? My AFR gauge was cutting in and out for most of the run, it worked for the whole 6 mile section mentioned though. It was also the warmest it's been since winter so that is also influencing the results.
