You can't lose the map by taking the battery off, so don't worry about that.
I'm also fairly sure taking the battery off doesn't really do anything anyway on the HDi as there aren't any adaptive parameters in those ECUs. It makes corrections for each injector when the engine is running, but as far as I know they aren't saved in the memory. I think an 'ECU reset' is just one of those placebo effects and people think it fixes things.
It does work on other ECUs like the petrol pugs but those adaptions are for the ECU to learn the position of the thorttle valve stepper motor and the EGR stepper motor, both of those we don;t have on a HDi.
