Land Rover Nanocom
For the land rover td5 engines (defender en discovery) Nanocom http://www.nanocom.itdesigned a OBD tool. It reads engine faults, read and wright ECU, gives you some gauge info, and it is possible to make a tripmaster out of it.
This device is stand alone or can be connected to a pc.
THe info on rev counting and temperatures can be read by the firmwire. But would it be possible to use the info wich comes in the pc and give it a new skin and is there a program to make the tripmaster visual onto a carpc?
