[T3] FI timing change for '72+?


Volkswagen Fuel Injection Technical Manual by Henry Elfrink
Page 16:
"Modified injection timing for type 3 engines
Starting with the 1972 model year, fuel injection timing has been changed for
type 3 engines.  A modified trigger contact unit changes the injection timing is
such a way that fuel is injected behind the closed intake valves for all four
cylinders."
Thus, fuel is NOT injected into an open valve, only a closed one.  Is this true?
Is there a way to identify if a FI car has this?  I didn't find any such info in
my Bentley.
