Hey!

I just wanted to say I just joined gassavers.org. I've been following this site for a while now and I decided to finally join. I have a 1990 Civic DX Hatch, and I've been doing a few modifications to it. Hopefully as I get more used to this site I'll find more stuff and be able to share it as I do it.

I'm very happy with my grill block:
Attachment 1719

My wheels are normal, cheap pvc wheel covers with polyurethane foam to fill in the gaps and putty to fill in the gaps in the poly. Then truck-bed black spray to top it all off. A lot more work than it should have been...
Attachment 1720

And here's what it looks like in general:
Attachment 1721
Attachment 1722

I put in the CAI because it really gave a noticeable boost in hp...but I didn't notice drop in FE. The DPFI really helps keep mileage down, but especially in low gears, I like the slightly higher performance if I need quick acceleration.

Welcome Neocivic!
What's your mpg (evolution) with all these modifications?

Re: Evolution

This car started out (combined) about 34-36 when I first got it (155,000).

Since most of the mods are aerodynamic, I notice a big boost if I'm driving highway, and I've gotten upwards of 58-60 on all-highway.

But generally I'm driving around in Kent, WA, which, if you've been there, you know it's divided in half by a huge valley. So city driving takes a hit. As of my last fill-up, though, I've been getting about 45-46 mpg in 3/4 city driving, which I'm really happy about.

I just began pulse and gliding leaving the car on and in gear because I've noticed, through my air/fuel gauge, that it burns super lean or even no fuel at all when it's coasting in gear.

Anyone ever pay attention to the gap between the windshield and the rubber apparatus that holds it? I've experimented with filling that in...the front window on my civic starts making noise around 50-55 mph. That's gotta have an effect. Maybe that'll be my next thread.

Ha, ha, you've got the right spirit! I'm living in Belgium.

But your result is fantastic. Congratulations.

I love the idea with the wheelcovers. Too bad the result wasn't better, but it's still a great idea, just might need some work to smooth it out more. Has it affected your wheel balance at all, or did you do a well-balanced job of it?

That's called Deceleration Fuel Cut Off or DFCO, and most fuel-injected vehicles will do it under some conditions.

I call that Pulse & DFCO. In my car it was less efficient than just plain steady cruising. I found it also to be an intolerable way to drive, constantly accelerating and decelerating at that level.

However, it sounds like your routes often include long descents; DFCO is perfect on long descents.

I've asked about it and it seems like that area isn't as important as it looks, as it's a low-pressure area from the slope change between the hood and windshield.
