Although there were systems named "L-Jetronic"
Sometimes it is taken as system family name of it's members:
L-Jetronic
LE-Jetronic
LH-Jetronic

What about 80's Saab, Volvo turbos?

AFM's act when pressure-differential is present. So in constant 2bar they
are shut.
Maybe they have AFM at the atmosphere-side and are "reading" air volume at 1
atm. No matter how much pressure will end up, ecu always knows the mass of
air and can set correct fuel.
