Multiecuscan

Hi all, just been looking through the various sub sections on multiecuscan relating to my 2012 1.3 Doblo 263 multijet diesel, it stated there were no faults and all was well BUT there is a section on the "CAN Setup / PROXI Alignment Procedure section and under F7 adjustments sub section "engine type" and mine is set to gasoline, my Doblo is most definitely diesel! So I know the answer would be to change it to diesel and do a PROXI alignment procedure but like I say Multiecuscan comes back showing no faults and the van is driving fine so should I just leave it well alone or is there an absolute reason to have this set to diesel ( yes I know that is the engine type etc BUT I am a great believer in if it isn't broke don't fix it) so any ideas or input would be greatly appreciated,
Thanks
