Just got home from the hospital...The Army likes to cut people open:

Sorry for the crappy pic, had a "tympanoplasty" done, other ears gonna get done in a few months, surgery sucks, that is all.

Tympanoplasty is the surgical operation performed for the reconstruction of the eardrum (tympanic membrane) and/or the small bones of the middle ear

Probably something to do with Japanese translation.
I have a noob question that I didn't want to make a new thread about for fear of looking stupid. Since our cars are wired to activate a pair of injectors every 2 cycles, does that mean we are injecting fuel during the intake and combustion strokes? So essentially during the combustion stroke, fuel is pooling against the intake valve, reducing atomization of the fuel and efficiency? I can't imagine how ANY car manufacturer would think this is a good idea when they were designing their ECU.
Conversely I would assume cars with sequential fuel injection get a crap-ton better mileage, and they are easier to tune pulsewidths and VE because you don't have to compensate for the pooling fuel.
I am just guessing on this though because I cannot find anything on this. Am I right in my assumption?

The difference is pretty trivial. Idle emissions are slightly reduced (particularly during warmup, when the head is cold), but there's not a huge difference. The fuel sprayed against the closed valve doesn't disappear, it just has to wait around a little while longer, so it's not quite as perfectly atomized when it goes it.
Think about this: The intake cycle comprises only 25% of a full engine cycle. (Yes, I know that there's overlap, but let's just use the 25% number because it's nice.)
At high load and high RPM conditions, injector duty cycle is often 60-80%. That means that even with all for injectors on separate channels and ideally timed, you're still shooting the majority of your fuel when the inlet valve is closed.

Nice to see that someone else around here understands the truth.
My uncle was an OR3 stationed at Norton AFB who actually did some of the rigging work in the soundstage where they built the moon sets that were used for filming the Apollo 14 and 15 missions. Pretty neat stuff- apparently Arthur C. Clarke was a consultant on the project, and apparently, DoD actually funded a lot of the visual effects budget for the production of "2001." They used the movie as a test mule to develop and refine a lot of the VFX techniques which were then used to do the moon landing footage.

I should name the mustang.
What would you call a girl who started off as white trash and later grew up to run with M3s (whatever the human equivalent of that would be)?

Oh yeah we really did not land on the moon either.
