What model Lycoming engine are you comparing with what model Continental engine?
Some Lycomings are fuel injected, and some are not.
Some Continentals are fuel injected, and some are not.
The 'standard' Lycoming fuel injection system is a 'mass airflow' system.
The 'standard' Continental fuel injection system is a 'continuous flow' system.
This is one of the reasons for the inherent dangers in the old wives' tales that circulate.
