I'm waiting for my UG to arrive. I do not have any instrumentation in my char related to FE except maybe the temp and fuel gauge
but I can still manage decent MPG by just managing the way I drive.
The reason for me getting an UG is to be able to monitor some things better, and hopefully get even more MPG out of my little car.
I won't see crazy increases to make me save the $100 I bought it for during the first 6 months or so, but after that i will probably break even.
Besides, you can bring it with you in every car you want / would buy later on that might not have the fancy equipment of you current car
