Re: Extrude Hone (actually: injection types)

  Almost the same. I think the bimmer has multiport injection, a dry
  intake, with multiple throttles, yet another variation. You really need
  the individual-cylinder mixture control capability to meet today's tough
  emissions standards. Now just add fly-by-wire CPU control of each
  individual throttle position and you really have complexity!

This is what my friend's M5 does; 6 throttle bodies, each with its
own fuel injection port. It always seemed like way too much hardware
for my liking. But the paint sure looks nice :-)

Only my cat shares my opinions, and she looks nice, too.
