does anyone know if you can buy just the software ?
i have a diagnostic lead that goes to the eobd plug already from some eas software i have already , will it work ?
Sorry the EAS cable is wired specifically for that. It doesn't use the normal OBD pins so won't do anything else. A normal ODB cable would give you access to engine readings.
If you :googleit: you'll find a variety of free ,paid , and hacked (slap on wrist) packages, which will give you access to the engine readings with a normal OBD cable. Unfortunately to get access to anymore than this you'll need LR specific kit, Testbook, Rovercom, etc.
