When is it really necessary to go mafless?

When you don't have the equipment or knowledge to tune a MAF based ECU.

Often people unwilling to learn Motronic opt for standalone.

There are also race (or high boost) applications where Motronic will not cut it, and the only reasonable (or affordable) way to do it is with a standalone MAFless ECU.

There is definitely NO reason to use Motronic MAFless, IMO.

MAFless can be done with the same way and same results at ME7.1 and ME7.5
If you have no idea about injectors calibration or injection calibration then yes ME7.5 will do its best to save the engine or try to follow the target because it has wideband!

If you can calibrate fine the injectors and tune well then injection calculation disabling the fuel trims then you can have an excellent MAFless with NO issues. But this need experience on ME7

there are plenty of cars out there using factory MAF ecus running mafless... i dont know how MAF based they are.. but GTRs come into mind.. evos.. sti's  most end up going speed density on factory ecus without issue.  its kind of commonplace

Those ECU's have speed-density as a control strategy built in. On ME7 it is still limp mode.
