Funny, I thought it was for those liquor bottles.

But I did notice that the fuel gauge dims and brightens depending on the angle of the sun....cool..

I like how the tach changes from orange to grey depending on the sun. And to the point where numbers and letters can be half orange and half grey. I find it very legible in changing light.

I'm sure I've read this already, but just re-discovered it today

'07 MC, 6spd, in gear, and wanting to apply both brake and gas, the brake apparently kills the gas input, so all I get is brakes, just when I wanted gas, too. I haven't tried it with DSC off (I just thought of that) so that's the next thing to try. Heel & toe shifting works great, though

Silly, the liquor bottles go up front in the door wells, that's what they were designed for --- really. Don't ever drink and drive!!

Yes! Yes! I love this! To me, this is a pinnacle achievement for the human race.

see below

I wanted to do a test to see what the difference between how fast the mini speedometer said I went versus how fast my gps said I was going at that point in time.

Difference in mini mph (false speed) vs. gps mph (actual speed)

mini: 40 70 90
--------------------
gps: 35 64 82


I just didnt think it was that much of a difference.

What wheels and tires do you have?

16 inch rims
215/40/16 ecsta spt

I know that will make a slight difference and I am going to test out with the stock 17 webspokes along with r/f. But I have always noticed that while driving on the freeway it seemed I had to take a higher mph to keep up with traffic. Ill test and post up my findings later.

O.D. 22.8"
911 revs per mile

Stock 17"
24.5"
853

You should expect a 7% increase from the stock speedo reading, which is already optimistic. You are probably looking at somewhere in the neighborhood of a 12-15% error.

What makes you think the gps speed is actual speed versus what is displayed on the speedo? A GPS unit isn't 100% accurate, I'd think the speedo would be more accurate to the GPS simply because of the accuracy of the satelllites locating the GPS receiver. We have a Garmin Nuvi 360, it's accuracy is <5 meters for location and velocity is .05 meters/sec RMS

Doesn't the Dept. of Defense prohibit GPS's from being accurate to <300ft?

Not anymore. Although they can make it less accurate or even unavailable to civilians at any time. Sorta nice to know they can make it so that terrorists and other assorted bad guys can't use it to deliver weapons.

jascooper - You are correct that the military GPS signal is far more accurate then the civilian one but even the civilian signal has an accuracy more along the lines of 3 meters if I am not mistaken.

Selective Availability (SA)

• "SA is the intentional degradation of the SPS signals by a time varying bias. SA is controlled by the DOD to limit accuracy for non-U. S. military and government users. The potential accuracy of the C/A code of around 30 meters is reduced to 100 meters (two standard deviations)."

Perhaps it is a little out of date?

Regardless I doubt its off by that large of margin.

Very outdated

If "it" refers to GPS, I think you are correct. If "it" refers to the 1999 info on GPS, I'd say it was way off.

Wow! First I was behind the times with toolkits that had no 16mm or 18mm sockets or wrenches. Now I can't paint that target on my roof without fear of being hit by a terrorist missile.

Now that I think about it my nav system always says "You have arrived." in the same exact spot every time I reach home. Right at my mailbox.

Mine also says I've arrived when I'm at the mailbox. Unfortunately, the mailbox is a long drive from the house. You have to climb up a switchback drive for an altitude change of about 400 ft. Then pass by four other houses.

I've been to places where the NAV arrival poiont was several houses off, but I think that has to do with accuracy of its address information, not the GPS.

That spec from the Dept of Defense is out of date. As I said, the Garmin Nuvi 360 has an accuracy of < 5 meters so it is accurate to within 16.4041 ft or 16 ft and 4.85039 inches. You can easily check the accuracy of the various units by going to the manufacturers website and finding the spec sheet for the model in question.

Correct.

Living in Iowa I have friends who are high tech farmers. There is a trend to what is called precision agriculture. Satellite imagery, GPS and computers are used to precisely map fields for application of fertilizer, pesticide, herbicide and seed. I don’t know all the details but they tell me that the system allows them to automatically put down only the required product where it is needed and avoid using too much or too little in any spot in their fields. They tell me the system is accurate almost row to row, that would be just a meter or so.

I keep pushing my car harder and harder and I had no idea my MCS was this fast. I just feel sorry for the people who bought 2006 instead of 2007 thinking that the horsepower increase was just 5HP.

Yeah, "it" refers to GPS.
