I've often wondered about this. In the early '80s, GM started pressurizing
their carburetors, and some ad guy with a lot of contempt for his
customers' mechanical knowledge, called it a "throttle body injector",
which is a name that could in truth be applied to any carburetor,
pressurized, computer-controlled, or not.

Sounds to me like manufacturers with real fuel injection, immediately
got on the bandwagon with names like "direct injection", which seems
to mean "ours is REALLY fuel injection".

Besides these, anyone know what "Tuned port injection" refers to?
Inquiring minds want to know.   :-S
