Hi jonEmetro - welcome to EM!
First: great car nickname.
Second: if you're going to start doing engine-off stuff, you'll need to rig a kill switch if you want the ScanGauge to keep tracking mileage properly (because of the car's OBD-II protocol, it'll reboot every time you key-off, and you lose distance data).
I don't know how much flexibility/pressure you have with traffic in Ramona, but with engine-off coasting and/or pulse & glide (if you want to go that extreme), there's a lot more MPG to be had from your car.
