Hi, Although I have owned Land Rovers for donkeys years I have never owned a TD5 until now. I would like to fit a dual battery system with a split charging system. I have done this a couple of times on a 90 but now I have the ECU to contend with. If I disconnect the battery will I then need to reset the ECU? will the electrics ie the ECU be able to cope with a dual battery system or will it need reprogramming? Help would be greatly appreciated
