So want to aquire more knowledge about that from you people and share want i know.
ECU - engine control unit. basically its a computer that controls almost every action of your car. by default car manufactures will write some codes to it and car will behave according to it. for example. take nano, when it reaches 105kmph the fuel to the engine will be cut off this will be written in a program which is also called set of protocols.
ECU remap is just changing some values or modifying the stock programs. in case of the figo diesel. he may change turbo timings, fuel intake ratio , etc.
