It looks like both those packages read the older K-line (or L-line) protocol, which is relatively easy to decode on a computer.I'm not a software or hardware engineer, so maybe the answer is obvious, but I'm curious why the battery pack data, or for that matter, all of the OBD information, cannot be accessed simply with windows software? That is how I access the OBD on my Subaru (open source FreeSSM and RomRaider) and my Hyundai (a commercial OBD software product). Why the need for the intervening hardware?
