Hello, I would like to have installed the OBD II(on board diagnostic), PC version, for my Honda Element 2004. Does anybody suggest where should I buy this system (s/w and h/w) at a reasonable price? I have already installed in my car a laptop for GPS navigation system. Does this ODB system indicate the fuel consume? At 25000 Km, my Element started to become more economic, I did 550 km with one full tank, combined city (50%) and highway (50%) ... Thanks, Chris
