[Ovmsdev] Nissan Leaf

[Mark Webb-Johnson]

Robert,

Something like one of these:

http://m.ebay.co.uk/sch/i.html?kw=Obdii+y+cable&isNewKw=1&pgn=1&epp=24&mfs=GOCLK&acimp=0&itemId=&cnm=&cid=&sqp=obdii+y+cable&_trksid=p2056088.m2428.l1313.TR0.TRC0.Xobdii+y+cable

http://www.amazon.co.uk/gp/aw/s/ref=is_box_?k=Obdii+y+cable

Something to plug into the car obdii then give you two sockets - one for the logger and the other for leafspy.

Regards, Mark

P.S. Probably best to give me 1 log file first, to make sure everything is ok.
