Oddity in main odometer and trip odo.

[cruisinTX]

I like to capture images of different things on the odometer. I guess I'm just a numbers geek, but palindromes, sequences, 10K, 100K, etc. get photographed. Today as I was watching my main odometer for a palindrome, I took note of where it changed in relation to the tenths number in the rest B. I noted it was no where near consistent. Sometimes the last mile would change after 0.9 miles and up to 1.2 miles and everything in between. I just found it extremely odd in that the last mile should have changed at a consistent tenth. I suppose this speaks to lack of quality control as seems to be the case for BRP. :banghead:

On all of my bikes when I'm watching for something like this, the last mile digit changes consistently at one mile each time. Doesn't matter if it .1 or .9 or any other .x it is exactly the same every time. :dontknow:

In 69,539.2 total Trip A miles (based on Trip A miles at every fill up) my odometer reads 69,611 or 71.8 miles over total trip miles.

Put your odometer into km mode, then watch how they correspond. The actual data recording is probably being done in km (remember, the bike is metric, not English) and then divided by 1.609344 to display miles. If you convert a series of km from 1 to 100 you'll see a variation in the tenths part of the resulting miles due to rounding. I ran into this one time when I was correlating a series of Celsius temp readings to the displayed value in Fahrenheit. The instrument native number system was C.
Here's a series of numbers to show what I mean.

ya, I fully understand metric conversions; been doing them since 8th grade math class in 1968 when we were told the US is going metric. What I'm saying is that with today's electronic technology, there should be zero difference between the Trip meter and the main odometer. If the main odo clicks over 1 mile the Trip meter should have measured that same 1 mile, not .9 or 1.1 or 1.2 miles. Both of the VW TDIs we owned were spot on all the time. I guess the Germans have a better understanding of math using electronic technology than the folks at BRP.

Hmmmmm....Never noticed or watched my trip odometer and odometer close enough to see if there is a difference.

I did notice the road, beautiful scenery and nature as I rode though. I will look and see what mine does when I hit a really boring road...... oh wait, I can't find a boring road when on my spyder.

This issue came up shortly after I began following SL in 2014 before I bought my Spyder. It was just a thread about the variance between trip meter(s) and odometer. I created a spreadsheet to track fuel consumption and cost and included the variance issue just to see how inaccurate my odometer was.

I let this kind of stuff ride. Having to much fun enjoying the ride. :yes:

Ya know.... in all honesty, if they can’t build a simple clock that keeps time how could we expect the odometers to work properly. Don’t get me wrong, we LOVE both of our Spyders but it’s the little things like that on VERY expensive machines!

:agree: Live to Ride; Ride to Live! No boring roads; just bored people!:joke:

You will get an almost exact correlation only if the raw pulses from the wheel sensor are what is converted to produce the miles numbers. What I think BRP has done is count the pulses, convert them to km in 1/10 km increments. Those numbers are then converted to miles. Run a long list of 1/10 km numbers and divide by 1.61 and then look at the column rounded to zero decimals and one rounded to 1 decimal. You'll see the 1/10 column numbers stay the same as the whole number changes, and also change by 1/10 as the whole number changes. This is due to rounding. When you reset the trip meter you should see the tenth number value change back and forth from no change to 1/10 tenth as the whole mile number changes. From my calcs the no change in the trip decimal occurs about every 5 miles.

All I can suggest is that the other odometers you've observed used the raw data to generate the miles numbers and separately the kilometer numbers, or generated miles numbers only.

Fatcycledaddy, I see by your map you have been in Utah. If you drove I-80 between Salt Lake City and Wendover, NV you found a straight flat "BORING" stretch of freeway going across the salt flats.:lecturef_smilie: If you did not drive that part :congrats:

We have been to Utah three times, two on the Spider with the camper and once on the Yamaha Venture with camper, and have always loved it. We hardly ever run the interstates, its back roads and byways for us. I got some info from UtahPete on some great places to ride and visit the last time we were there.
We will not be out there in 2021, but Lord willing we plan on being back there in 2022.
2021 will be black hills, bear tooth hwy, and more northern Rockies again.
We followed the river from Grand Junction CO down towards Moab, and did Arches the first two times. Last time there because of all the flooding in MO, we took a southernly route down through parts of NM and up into Hurricane.

Maybe it's a metric clock?!
