ELM 327 Bluetooth OBD 2 for Nissan Leaf and Leaf Spy Pro: This one Works GREAT

Update: It sort of works when the Leaf is powered off. It's not consistent. But in most cases you probably just care about using it when it's on. If you want to see stats when the Leaf is off and charging for example, you have to kill the app and restart. Hopefully that gets fixed because IIRC it used to work better.

When the Leaf is on, like when you're driving, it still works great though.

I got this one from Amazon and it works great with the Leaf Spy app.

I also bought the Pro version of the app.



I have had zero problems with it. I leave it plugged in all the time.

The only thing to watch out for is don't leave the app running when you are in Bluetooth range of your Nissan Leaf.

It will cause a relay to click over and over, adding wear and tear, and using your 12 volt battery. You will hear it when near the car: it's a very audible erratic clicking sound.

If you're not familiar with the app, click here to see it on Google Play. I used the free version for a while, but I think the Pro version is worth the $15. There's also a 'midrange' version here.

The free version is here.

Enjoy!
