Interesting - I can understand the timing adjustment and thanks for that explanation.
I was under the impression too that the carburetor had to have different jets in it for different altitudes - either leaning out fuel/air mixture because of less oxygen at higher altitudes. Does the ECM do that automatically these days for the fuel injection?

In trying to calculate MPG for my new EX-L, i tested the accuracy of the odometer. In a 100 mile test, I discovered it was reading 3% low (showed 97 miles). Have any of you determined the error rate of your odometers? What is the range of error rate?
 
Thanks

If so, more important than MPG, your warranty will last 3% longer!
 
As for MPG - the difference is totally insignificant. 100/6 gallons = 16.66,, 97/6 = 16.66, 300/12 = 25, 291/12= 24.25

Uh oh. Didn't Honda just settle a lawsuit over this very thing? I forget what year(s)and models but I just read about it recently.

Just curious, how did you determine that your odometer was inaccurate? It's sort of a point that was glossed over, I thought. I know tire size has an affect, how large of an affect I don't know, but anyway how you determined the 3% inaccuracy would be interesting to find out. I guess I've never put much thought into it.
 
I know that when people start changing tire sizes they say that you need to have the car 'reset' to make up for the larger tires. I don't think that was what you did, but I tend to get side-tracked. Sorry about that.

I knew a guy who determined his speedometer was off by using the mile marker signs along the highway.
 
Then I learned that they use the county pick up trucks to place those signs!
 
So, whose speedometer is off?
 
And who really cares? I sure don't! a 3% error if this is for real is nothing. I don't think a speedometer/odometer was ever meant to be a precision measuring devise.

Except that, after 100k miles, your odometer indicates you've taken an extra trip from New York to Los Angeles. . . . .

Unless, it is off in the opposite direction.
 
On a 100,000 mile car, nobody would care anyway.

....if you have the extra cash, get the V6. The gas mileage between the 4 and the 6 is negligible. At least that is what i think i will be doing after reading a lot of these posts.
