Upload the maps to the ECU with Rovacom, read and save them with the Nanocom.
I have a performance map for mine installed by Davis Performance (by previous owner). I bought a Nanocom and after some reseach found the map is for a EU3 Disco 2 while I have a EU2 Disco 2. I then found after installing a standard base map that the perfomance map was causing about 3L/100km extra fuel use.
I contacted Davis Performance and asked could they supply the correct map. They didnt seem very interested to start with and then said they use a different system to the Nanocom and it was no use for me to send them the current map and them to send me a new one. It was all too hard, mainly without their support so I have decided to get a TD5inside map, when I can afford it.
Happy Days.
