Thanks, that was a big help. I've now figured out that the Wikipedia page on how OBDII CAN messages work (http://en.wikipedia.org/wiki/OBD-II_PIDs) is completely wrong for the Leaf: CAN ID values aren't ECU identifiers, they are message IDs. By selectively filtering for each CAN ID (ATCM 7FF then ATCF nnn where goes from 001 to 7FF, each followed by ATMA), I've found 49 messages that happen at least twice per second and together total over 1,700 messages per second.
Now the LEAF messages documented at <https://docs.google.com/spreadsheet/ccc?key=0An7gtcYL2Oy0dGRaSWl6VTV2eXBQMy1ON2xZSzlMUXc#gid=1> make sense. I can see the odometer value!
Thanks for the help!

First, I am using an Amazon Kindle HDX and I have the light version of Leaf Spy downloaded and I am using a Seagate scan OBD scan tool with a 2.1 version ELM 327. I show in my settings that I am connected to Bluetooth, the problem is with the app, it goes looking for EOM then connect to EL M and every once in a while it will say waiting and in one half of a second it will count up to 11 and then say retry ELM 11.
Also in the setting there is a drop-down box that allows you to choose port one through 30 or choose secure, in some of the Amazon reviews and referring to a leaf, some have said it works on port 12. I have gone down the list twice and wasted a lot of time. I was hoping to get some feedback on this thread because it is listed in the user based manual, I have had no such luck and was hoping one of you leave gurus would have an answer and help me out. Pretty please and many thanks.
On a sidenote, for my iPhone and Leafstat app , I have an ELM 327 interface that uses Wi-Fi and that works great with my iPhone but I have no option to use it with the leaf spy app.

and you also don't want to be plugging/unplugging something from it constantly. I picked up this low-profile right-angle Y splitter based upon a suggestion here or in the wiki; with it, I can have the OBDII adapter tucked away out of side without stress on the port.Agondonter wrote:The OBD port is not designed to have constantly plugged-in device in it (its wobbling) ...
