Alrighty folks - I haven't forgotten about this. Sorry to bring this old thread out of mothballs, but I appreciate all the responses I received, and I didn't want to lose all that information. Thank you to everyone who has offered suggestions!
So - I got Leaf Spy Pro and a dongle, and I've been keeping track to my heart's content and trying to improve my range. My wife rolls her eyes as I get my phone out at the start of each drive, but I appreciate all the detail LeafSpy provides.
However - consistently the overall range isn't getting any better, even in the summer (I did get better range in the summer, but not that much better).
Using the "Charge" time frame setting (stats from the last charge) on LeafSpy Pro, I can see that on an average bit of driving between home and work, I get a solid 6.5 km/kwh (some times more). I do drive up a hill to get to work, and up a hill to get home, but I'm getting the 6.5km/kwh average despite that. Based on a 40Kwh battery, I should be in excess of the 240km range. In fact, I should be getting close to 260km! (But I'm getting closer t
I've added air to the tires (thank you), but I can't stomach the idea of going all the way to 40psi or above - I've stopped at 38psi.
I appreciated Daveinolywa who showed how the GOM and LeafSpy differed, like the GOM was building a secret reserve. I've seen the opposite - the GOM is always significantly higher than Leafspy Pro, unless I'm averaging over 7.17 km/Kwh.
But - the one thing I just spotted on LeafSpy Pro was that after a 100% charge (97.9% SOC on LeafSpy, 454 GIDs), my remaining power is 35kWh (12.5% reduction from the 40kw/h advertised). I could understand being down app 5% (since we can't use 5% of the battery capacity, right?), but 12.5% is excessive. This seems to be a smoking gun, but I wanted to make sure this wasn't the norm.
What I don't understand is how the GoM is completely oblivious to the lowered battery capacity.
So - my two questions for this post are - is seeing 35kwh correct when the car is fully charged and how do I use LeafSpy Pro to identify a bad cell? Because I've had it into the shop three times because the range hasn't seemed right, if I take it a fourth time I do want the thing fixed.
