civic d16y4 22km/l

[D15r]

Hi guys I've been getting my civic ek1 tuned up for economy and starting to see some good results, bring on summer, and aero mods.
840Km on a 38l fill, 22km/l.
Mixed driving city country highway, mix weather, 80~90km/h max although did go quite fast a few times and coasted down + a few wot runs. cruise no eoc but obviously lots of coasting. Pretty stoked withe the car since it isn't the most economical civic and the motor is tired. I know I will easily average 22km/l from now on as the ms rack has only just gone in and gives the car much more power.

Mods:
14x 5" steel rims
165/70R14 bridgestone ecopia lrr 45psi
Lowered
Disc hub caps
Brakes set for low friction
Manual steer

Planned mods:
wheel spats*, side skirts, air dam, splitter, grille blocks, kamm back, vx trans, squared off trailing edges, enclosed rear wheels, Mirage 14x4.5" et46, 155/80r14 tyres, mpguino, 4~2~1 header, d15b engine swap, 3 plug single wire o2 ecu swap.

Great numbers!

What are you using for instrumentation, if anything?

[D15r]

Hey man thanks, d16y4 with their quirky/cheap batch fire efi system and 2 plug ecu must be rare on here, hopefully I can add to info on them .

No instrumentation on board, just fill to fill, but i have an mpguino on the way, it will be interesting to see where I can improve my technique. it will also be a necessary tool for testing/proving mods.

For tires go with 165/65R14 Bridgestone Potenza RE92's. The MPG tire.

Thanks, i already have some Yokohama blue earth, probably not as good, 165 65 14 but anyway i worry it's the smaller diameter will spin faster and cause noticeably more friction

D15r, thanks for sharing! I've got a Honda Civic (but 2015), will try to do something of the kind

Nice stuff! I hope my numbers will join yours soon...around 43mpg (~18km/l) but I just fixed my valve stems so I can get air into the tires, and frankly I'm learning both the car and driving techniques with standard shift at the same time...

...anyhow, good real-world numbers, especially without extra instrumentation!

PS, Honda manual steering is Honda's gift to mankind. It's delightful.

[D15r]

My manual steering isn't the best as its converted from power steer, it gets really tight on hard turns so isn't the best feel, great for ecomony though.

Good luck with your cars, get your rolling resistance down down and spend lots of time in neutral!

At first I misread the thread title as 22l/km and was like... huh? Great numbers though.
