The 16V uses a pressure regulator that opens around 5.8 bar.
The 420 & 560SEL's fuel pressure is 6.2-6.4 bar. The only difference is the regulator. The injectors from the 420/560 engines also flow more fuel, but the line connections are different.

Yes the O2 sensor info to my meter allows good info on fuel mixture.
