...I have noticed recently that when I log into carwings from the Owners Portal on the computer that the miles given on each day is not ALWAYS THE CORRECT NUMBER. Everything is set up in settings to transmit from the car to the carwings. And I am getting data each day--just not all the miles on certain days. Is this happening to anybody else? What am I doing wrong?...
Here are my suggestions, for you and other CW users.
All 2011-2 LEAFs, AFAIK, have reported the same Carwings odometer and Dash m/kWh error of consistently under-reporting by ~2.5%.
So if your CW miles driven is ~2.5% lower than your dash odometer miles, and your dash m/kWh is showing ~2.5% less than your nav screen m/kWh (0.1 m/kWh lower below ~6 m/kWh, and 0.2 m/kWh lower when you are getting over ~6 m/kWh) this is "normal" for 2011-2012 LEAFs.
Hopefully, Nissan has fixed this error in the 2013s. Any readers have a CW equipped 2013? Please check and report back.
If you are "missing" more miles than this, go to the "rate simulation" page at the CW site.
Here, each "trip" (each start/stop cycle) will be individually reported. Make sure that each of the "trips"you have made each day, is showing up. Each trip will show the same ~2.5% under-report of miles driven as your daily total, and each m/kWh report there will match your dash (if you reset it) for the corresponding trip, again showing the same ~2.5% under-report error.
The Dash, nav screen and CW m/kWh all are mathematically "correct" as a function of the total kWh use reported by CW for every trip, day, or months driving.
It's just that the dash uses the same ~2.5% understated miles to make its calculation of m/kWh as CW does, while the nav screen is always accurate as a function of reported kWh use, as it uses the dash odometer miles, for the m/kWh calculation.
BTW, while every LEAF driver, AFAIK, has reported the dash odometer as very close to correct, while using stock tires and wheels, IMO it wouldn't hurt to confirm your dash odometer is correct, by checking with another source, such as Google maps.
Now back to the "rate simulation" page, If you are missing any "trips", that you made on any given day, and every driver is pushing "accept" every time, please report back.
I have missed only a couple of "trips" in the ~12,000 miles since I've been using Carwings (since an update corrected errors in the early LEAFs) so I believe they probably have all been due to operator error on my part, as I make a very quick stab at the screen, and I think I probably just missed "accept" a couple of times.
