The early M104 used the old mechanical CIS-E fuel injection, and the 3.2 liter in the 1992 300SE was an LH system, used only for this one year.
The 92 and 93 300SEs are identical, both using the same ignition components. Although the nomenclature was not adopted until later both used the hot film air mass meter. You may be right that the 93 124 represented an evolution in engine controls.
I am pretty certain that 1993 300SE's use the same HFM system that other 1993 W124's use (3.2 or 2.8).
I could be wrong, but I don't think so.
I cross-checked this with MBUSA's webpage, and it also shows that 1993 300SE's went to HFM....
