97 Civic HX coupe; lean burn fuel system is oem. Similar to earlier VX system.
I have to say, your wheel skirts are inspiring. You made it look very easy. I hear you about the indent above the side molding. Doubtless someone with body work skills would know how to fill the gap nicely with Bondo and then paint it, but I'm not that person!
As for the WAI - I set that up on 3/7/09. You can see the note in my fuel log at
Fuel log: - - EcoModder.com. That's 11 fillups back from the most recent one, so you can count bars on the graph to see the mpg trend after that. That time also includes the spring warmup so some of the credit simply is due to the weather.
One major aim with this car is to keep it in Lean Burn as much as possible; that reduces fuel consumption by about 20-30%. The first fillup with WAI was pretty good, the next two two were not so good but one tank wasn't driven by me (see notes in the fuel log). I've since learned that my car needs a full block on the exhaust (a/c) side of the grill to keep the cat hot, to get max Lean Burn time. I had some CELs with a cat code but none for a little while now; even so, I think the cat is not in the best shape.
I've also learned that in current weather (maybe 80 deg. daytime??) I need to close off the WAI ports and go with the oem intake. IAT is up around 100 deg F. with oem intake and I don't trust it to be OK if hotter. But I still need to keep the cat side of grill blocked.
