I think the method learned by the early Gidmeter pioneers of wrapping the thick cable around the steering column and kindof tucking it in between the column and main display works pretty well to secure (and hide.. at least on top) the cable. So coming out of the connector facing away from the driver, the cable turns 180 degrees under the dashboard then comes up along the underside of the dashboard then wraps around the steering column.. From there where you put it is up to you, but at least that keeps the cables away from your feet.

When I had my LEAF SGII, I didn't wrap the extra around the steering column where it could be seen, but stuffed the extra into the steering wheel space which worked very well. I ran the cable down alongside the console and mounted the gauge with Velcro on top of the console (on the dash).

Received by LeafDD today, can't wait to try it out. The LeafDD joins my original Gid meter and the Leaf Battery App (which can't report true Gids yet, of course), so I will have multiple backups.

Initial impressions of LeafDD:

1) I love the OLED display, very easy to read even with polaroid sunglasses on which is my main requirement for a meter
2) Having Gid% and battery pack temp on the same screen and sized large enough that they are easy to read at a distance - fantastic
3) After watching the brief video earlier in the thread I was able to change settings without any kind of manual - very intuitive
4) I may have to retire my original Gid Meter

One oddity: the temperature shown (degrees F.) does not quite match the temperature shown on the Leaf Battery App. Reads about 0.4 degrees lower than the Leaf Battery App maximum temp. I am assuming that the displayed temperature is the maximum temp. If so, either the Leaf Battery App or the LeafDD is slightly off.

The LeafDD saved my a** tonight: I hit LBW and the LeafDD said I had almost 30% left. I made it home easily and I would have been worried otherwise. Why are these cars starting to 'squirrel away' capacity under LBW (like I read about last year)? I'm hoping the (new) software update "fixes" that problem, because it's obvious I have a lot more range left than the gauges are showing me.

I assume you mean 30% SOC, because LBW happens at 49 Gids = 17.4% Gids. I would not consider % SOC to be a good guide to how much energy is still available in the battery pack. On the LeafDD, the % Gids shows a small G below the % sign, the % SOC does not. Be sure you have % Gids set to see how much juice your Leaf has left for the trip home.

Since reporters and other delberts were running out of battery and giving the car bad press early on, Nissan changed the battery gauge to hide about 1.5 bars of capacity under the last bar as a "reserve." This "update" happened in early 2011 and it has been this way on all cars since. I don't see it changing at any time in the near future...

It already has in the 2013.

Based on the 2013 I drove that belongs to a friend, and his gid meter, I saw pretty much the same reserve battery capacity after the last bar extinguished as on my car... What makes you think that it has changed?

I'd recommend starting with raw Gids.. We know LBW is 50->49 and VLBW is 25->24.. I wouldn't count on having anything under 5 Gids but YMMV. Honestly if you're under 25 Gids you're probably better off watching the little battery voltage dot.. As long as its not pegged on the right (330V) you've still got a little juice left. I get nervous when I get down to 345V. The true SOC is fun to watch but I don't know really where the bottom is.. Same for Ah*SOC. None of the energy display options on LeafDD will get down to zero... In all cases the car will be dead before then. When you get down to single digits on Gids you might even be better off on the 3rd page where you can see the lowest cell voltage..

Not sure what to make of the temperature descrepency.. I should hope I could handle 32+1.8x!!
Page 1 shows the max, but also graphs the relative temps of all 4 relative to max. Page 2 shows all 4 temps in Celsius.. Also note the LeafDD shows temps down to 0.1 degrees Celsius. If the android app is just taking the raw data from the car it's only 1 degree Celsius resolution.. That probably accounts for the difference. LeafDD interpolates tenths of a degree based on the raw thermistor A/D values.
