OK, we have determined that the speedometer is 3 to 4 mph to fast and the MPG reading is 3 to 4 mpg high. How about the odometer? Is it giving the actual distance traveled? Jim
It is on my car. Have verified the the odometer is not tied to the speedo with my GPS. It is only about 1 mile off every 70+ miles on my old runflats.
I have almost 110K miles, more or less. Way back when, I remember the same question about 1st Gen Odo's. Seems the MPH keeps you safe, the MPG keeps you happy, and the distance traveled is right on. Mark
The ODO is usually right on or very close to a GPS. Many OBDII devices will show mph in it's accurate form while the speedometer display will be off. The car's system knows the correct speed but is programmed to display it with a certain % of over-estimation for liability. There are variations due to tire wire/size.
I believe the odometer is going to be off if the tire size is not exactly correlated to the speedometer. It is my understanding the MINI speedometer only has one input and that is revolutions per minute so both mph and odometer reading will be off with any tire size variation.
Checked my 06 MCS with a GPS and its 2 mph fast using the 17" wheel with 205-45-17 tires. This site seems to help with tire size differences as far as speed goes: 1010tires.com Tire & Wheel Tech
I hit the mph reading on my Garmin 760 by accident and a new screen popped up. It gives all kinds of trip information, plus it tracks actual miles traveled which was just what I was looking for. Had no idea it was hiding back there. It also shows fasted speed reached and I swear I have no idea why it was reading 93. Not what you should have on during a traffic stop. Jim
104 is the most land based speed. We did take a GPS on a plane trip, turned it on mid-flight, and had an average speed of about 400 MPH stored for awhile:lol: One way to collect data for your MINI Mark
:lol: I would love to do that and then just happen to have that screen showing when the wife looks over. On second thought she might hide my keys. Jim
Some times handheld GPS' will skip a reading and cause erratic max speeds. Fairly common on a couple of my hiking models with track logs. Some of the track points won't have data so it skips to the next, making the speed reading jump up quite a bit.
