DDT4ALL is an Open Source software that is widely used by experienced Car enthusiasts/DIYers to adjust, amend default software settings. In order to use it, you probably require an OBD-II connector, a laptop with DDT4ALL installed.
I am not at all experienced in Car DIYs, therefore I am extremely wary of using it to avoid the possibility of messing with values that I don't understand and for the fear that I might really harm the functionality of the entire Car which would cost me much more
