Why the Civic VX is a superior highway fuel economy (FE) machine

I tell you, if one ever turns up that's in good shape and not too rusty, I'll be sorely tempted to pick it up. |
Why would a VX have greater potential than a Metro?
I'm mainly talking about highway FE performance. Despite the ability to achieve ridiculously good efficiency in city driving, I normally use my car more on the highway, where the VX excels and the Metro suffers. It's about the speed at which the 2 cars attain their EPA highway ratings. With wheel skirts & grill block (+5% mpg), the Firefly met its EPA rating of 49 mpg at 60 mph (flat road, steady speed). At 55 mph, I saw about 54 mpg. Dan, on the other hand has shown he can keep the VX in lean burn (without drafting) and get 75 mpg at 55 mph. Nuff said. If we made a top 10 list topic of: "MPG / avg MPH", the VX would be on top. I think I'd kick his butt in the city/suburbia though http://www.gassavers.org/images/smilies/smile.gif So if that's where you do most of your driving, the Metro may be the one to have. EDIT: I shouldn't be so brash: Dan says he hasn't P&G'd the VX much. maybe it's got monster potential in town too... |
Dan chimes in with some critical VX info:

Another VX plus...
Apparently the tuner crowd is throwing VX engines to the curb in their zeal for power. Making used working engines free / cheap. |
I can attest to the tuner crowd throwing/giving away the D15Z1 motors. That is exactly how I got my spare VX motor with only 110K miles on it for free. The poor kid didn't even want to try and save money/gas, he was too smitten with lust over the false promise of speed and glory.
The real problem with the tuner crowd going after VXs is the fact that they ruin the harness so it's harder for people to install a VX motor into non VX Civic. |
a look at what the tuner crowd shows how lost you can get re maping a engine management system computer.

How well do you think a vx motor would do for a crx with an hf tranny?
|
Also, is there a way to program a 90 crx hf for lean burn?
