'07 Civic 1.8L @ High Altitude

eds222 · 06-19-2007, 02:27 AM

Again, I'm a Newbie here so I have to ask for your patience in case this has been addressed before.
I recently purchased an '07 Civic Ex (1.8L). I live at 4100 ft. elevation (Bishop,CA.) and regularly drive up to 7500 ft. elevation to work (Mammoth Lakes,CA). Seems that everytime I try to excellerate from a dead start with the air conditioner on, I Bogg. I step on the pedel and nothing happens. I almost got T-Boned as a result. Does anybody know what I should do. Air to fuel mix ratio change? Hi altitude adjustment? Help!

You need to find some way to pack more air into the motor at that altitude. I think force induction will be excellent in this situation.

Call your local dealer service department and ask them if there is a different ECU program etc. for high altitude driving. However, most newer vehicles have basically two map sensors (often built into the same single device). One monitors the pressure inside the intake as all map sensors do, the other monitors the outside air pressure and automatically adjusts the fuel mixture accordingly. If your car has this it should get better as the car adjusts to the altitude change. Don't forget though that your car [u]will[u] have less power at higher altitudes. Thinner air means less oxygen. If that's the only problem then you are back to forced induction

Are you sure its the lack of air? Do other cars have this problem? Perhaps its the computer like others said.

turn off the AC right before you start moving.

its not even as cold as it would be if the car were moving

Good point. Altitude may not even be the problem. Does the problem go away if you drive at/close to sea level?

I bought it at sea level and did not notice any bogging.

doesn't the compressor shut off automatically when you accelerate.

Slowroll90 · 06-19-2007, 04:52 PM

no it stays running when you are moving.
all n/a cars lose power at high altitude.
when you get less air, the computer reduces fuel so the engine doesnt go rich.
and as you know, less air and fuel = less power.
forced induction or bigger engine is the only way around this.

Don't know, cold air keeps coming out from the vents.

Ok, Here's an update for those still tuned in,

Today I called Honda's 800 customer care line. The guy who answered the phone sounded like he was 12 years old ( albeit, a competent 12 year old). I told him my problem ( Bogging with air conditioner on) and after holding for 5 minutes he gave me a case # and refered me to a local dealer's service department.
Called them and have an appointment for Friday morning.

Here's what I'm chewing on in the meantime:
If this problem of mine is "normal", as some have suggested, and the car is running as designed, is this something that I have to live with? If it is, then I don't want to live with it! Its freaking hot here- 100 degrees today, yesterday, and tommorow. For $20K I would have expected something better.

I've had the car for only 9 days, 600 miles. I've painted the calipers and installed a Honda dash kit. Other than that, the car is the same as when I drove it off the lot.
Does anybody know what I can do if I want to upgrade to an SI? Will the dealer just take it back and credit me toward the purchase of an SI? or, will I have to "Trade in" and take the hit.

Doesn't seem fair, had I known this would happen, I would'nt had made the buy.

HELP!

For the cost of trading in and getting an Si it may be worth looking at an R18 turbo kit, and up there that will probably make you faster than an Si.

edit: although I don't know how much a turbo helps off the line during normal driving

Slowroll90 · 06-20-2007, 01:37 AM

turbo sounds good to me and im close to sea level lol
