I am noticing something similar. On 2 different GPS units I am getting a reading of 2% over in both MPH reading AND mileage on the odometer.
The speed isn't the biggest thing to me, but 2% at the end of my 45,000 mile lease is 900 miles.
I'm not jumping to conclusions just yet, but I will be...
And, as a side note, the charging stations at Walgreens are WILDLY expensive if you ever use one. Just map out the Nissan dealerships in your area - they're the best if they're convenient.
Looks like a great project. My car is a lease, is there anything irreversible if I turn my car in at the end of the lease, aside from the wires you had to splice?
It looks like the same procedure in reverse to remove them.
How have you liked them? Will you give us a Long Term Update?
I've tried looking here and hope I'm not duplicating anything, but I wonder how a grassroots letter writing campaign might work to get additional charging stations installed.
This isn't my forte necessarily, though I have mailed and emailed several malls and shopping centers around where I live...
