That must be the lean burn in my 5th gear. I still want to do a gauge though. Haven't heard of that one, does it plug into the obd2 test port?
Welcome and congrats on the car and your now fatter wallet. Going from 18mpg to 44 is pretty sweet! I have a 98 Civic DX. If you are curious, take a look at my list of mods and maybe there'll be ideas for you.

As for the gauge. I don't think the ScanGauge works with our sixth generation civics. That's why I bought an UltraGauge. It plugs into the OBD2 port under the dash, left of the steering column. Simple.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
