First of all, a 3 way catalytic converter does convert NOx, but it is very inefficient at doing it, which is why it's not used in open-loop systems. It can clean up some NOx, but it relies on the ECU to help minimize the amount of NOx in the exhaust in the first place.
Second of all, it's not the cat's job to burn unburned fuel. In fact if you run rich for an excessive amount of time, you'll actually destroy the cat.
Third of all, the ECU is not so stupid that it doesn't know if you are in gear or in neutral. Try plugging in a damn scan tool, and look at the parameter called, "Engine Load".
Fourth of all, the Impreza utilizes a MAP sensor, (or Manifold Absolute Pressure), which means that the ECU knows exactly how much air is present in the combustion chamber, as it is calculating it based on pressure and intake temperature as measured by the IAT, so the ECU will not be fooled by BOF valves. Besides stock setups have the excess pressure going to the low pressure side of the turbo. BOF that vent pressure to the atmosphere are illegal (at least in California).
One of the guys even verified that the injector pulse width goes to zero on his WRX during the conditions I mentioned, and shows the injector pulse width going > 0 when the RPM drops to around 1500rpm or so during deceleration.
I don't know what you're trying to prove, but perusing the link you posted, even people on that board says the subie has deceleration fuel cutoff. The one person that responded that it didn't was an idiot, becuase he said if the ECU cuts fuel while decelerating, the engine would stall.
Also, you are quick to judge just based on what you think you hear is unburned fuel popping in your exhaust. The only way to tell for sure is to plug in a scan tool. But I can tell you that if you really were running so rich, that you really did have unburned fuel popping in your exhaust, I can tell you that you would FAIL a tailpipe emissions test. One of the fail conditions I've seen in the paperwork (at least in the west coast), is unburned fuel in the exhaust.
The fuel map is irrelevant, the ECU uses other parameters to help determine what the actual injector pulse width should be.
For example, if you spin the tires, the ECU will may also cut fuel to limit engine power, despite the MAF reading air passing in. The ECU does not just blindly use the fuel maps and MAF readings when determining injector pulse width...
And for your information, Subaru does employ deceleration fuel cut off... At least I know the Impreza does. But otherwise pretty much all cars these days do, because of tightening emissions requirements.
You are so off, it's not even funny. YES, the fuel injectors DO TURN OFF. If you don't believe me, I can email you the pages from the factory service manuals from Toyota, Nissan, and Honda, which explain this feature, which is present ON EVERY fuel injected car. The main reason for this has nothing to do with fuel economy, it's emissions related. (Tho fuel economy is a minor side benefit). When the car is decelerating and the car is in gear, the ECU would normally decrease the fuel. Hoewver, this can also cause a lean condition which would in turn cause very high NOx emissions. This is why the ECU will simply cut fuel.
You can't compare this to shutting off your engine while coasting, then turning it back on.. When you "shut off" your engine, you are also cutting power to the ECU. When you start it back up, the ECU has to go through it's setup-phase all over again, as it has to figure out the crank position, cam position, etc, etc.
When you are decelerating, the ECU is simply commanding the pulse width to the fuel injectors to 0. It is still actively monitoring the rest of the engine.
If you still don't believe me, I can post a video of a scan tool plugged into a Honda Civic that shows the injector pulse width going to 0 whenever you lift your foot off the gas while the engine RPM is > 2000 RPM.
Great... So I'll make sure to have lots of "legal" music and movies on my laptop, so when they image my HD, I'll call the RIAA/MPAA and tell them the border folks just illegally copied a hundred gigs of their copyrighted works....
Personally, I think that's nonsense... Most Libel cases deal with the presentation of falses under the pretense that they are factual. This is something that an OPINION is not. No need to keep opinion to yourself. This is a free country. You can share your opinions, just don't try to claim them as fact, and you'll be fine.
Are you serious? Why don't we ban watches than, and have ushers posted at the doors to confiscate them from everyone, because they might hit the indiglo button, and disturb everyone.
They should board up all the bathrooms, because apparently it's disturbing to get up from your seat to use the bathroom. We should also ban food and drink in the theatres. The crunching sound of popcorn is disturbing. And the sound of people belching is annoying too.
It's already illegal to blast your stereo at 1am. It's not illegal to have your cell-phone on vibrate.... So if I'm a doctor, and I'm on call... Are you basically saying I can never go watch a movie at the theaters again, since they'll have jammers? Nice.
There are also some medical devices that use wireless technology to relay information between an implant and an external device. These people probably won't be able to go to the theater either...
Whatever. Just because it's shot on film doesn't mean it's captured or stored in high def. You work in the industry? I didn't think so. One of my clients is in the production business. Their filming equipment for HD productions is completely different than standard def productions.
If "everything" was filmed in HD, then you'd see more programs aired in HD on tv. A LOT of the content that is aired in "HD" is actually just upsampled standard def content.
If everything on film can be HD, than why do some people pay extra to get 70mm filming equipment vs 35mm or 50mm filming equipment?
The truth of the matter is, that there is a lack of HD content today. Its almost a chicken/egg problem. People don't want to replace with HD equipment until there is more content to show. Content providers don't want to spend $$$ producing HD content until there is more equipment to display it.
Too bad most things aren't filmed in HD. For now, other than storage space, there isn't much benafit to Blu-Ray. It's like buying an HD-TV and just watching regular TV. There isn't much HD-Content out there. (Yet anyways)
I have multiple voip clients at home, and I'm running a voip pbx server at work, all of which are behind NATs, and they also work fine. You just need to know how to configure them:p
The user is not the one that needs to make the change. The app developer is. If the app developer, for example, decided to use the Intel Performance Primitives library, to build an MPEG decoder, then the resultant decoder will be optimized for an intel processor.
The developer would be stupid to assume that using such a library would accelerate a non-intel processor. What I described was that Intel should not be responsible for accelerating code for a non intel processor. AMD is fully capable of building their own performance primitives library, that the app developer can use, depending on what kind of proc the system has.
You can't really shame intel for this. Nobody is forcing anybody to use an intel compiler, or the intel performance primitives in the first place. And when you link in these "3rd" party libraries such as the IPP, you are free to link in your own libraries to help you build your app, if you are running on a non-intel processor.
No this is not a matter of intel screwing over AMD. We're talking about the Intel Performance Primitive Library. It's a library designed to optimize code for Intel Processors. That is it's functionality. That is it. It is NOT breaking AMD processors. It's not going to cause it to not function. It just won't accelerate an AMD processor. It's NOT INTEL'S RESPONSIBILITY to do that. AMD is perfectly capable of building an AMD Performance Primitive Library, and giving that to MS to compile into the OS. The fact that they don't do that should say something.
One could also argue, that Intel is within their right to do that, becuase Intel cannot be held responsible if for example, AMD screwed up their SSE2 implementation. It's not like there's a certification process for getting an SSE2 logo. With that being said, Intel would be in even bigger trouble, if AMD screwed up SSE2, and the IPP library caused a crash on an AMD proc. It doesn't matter whos fault it is, from the developer's perspective, it could look like Intel is doing something on purpose to screw up AMD, when they weren't. Therefore, it's understandable that they didn't use SSE2 as the baseline.
Besides, from a developer's point of view, the developer is perfectly capable of doing an
A developer would be "lazy", if they just assumed an INTEL PERFORMANCE LIBRARY, was going to accelerate other platforms. You really expect intel to do all these ifs and checks, to see what a non-intel proc has, and do optimizations based on that? And then spend $$$ to QA that code?
technically, you own the DVD, you don't have a license, becuase a license was not presented to you before purchase. There is already precedence for this, with adobe. It was determined that sales doctrine applies, because you cannot present a user with a license after purchase, which essentially negates the purchase agreement, and turns it into a lease agreement.
Sure... Look here. They are priced right now, anywhere from $1000 US to $2000 US. Blank media is available right now stateside, for about $25 for the 25gb media, and $50 for the 50gb media.
I think I remember seeing somewhere that LG has one available, that will be closer to $900 US, which for right now seems reasonable, as they did just come out within the last year. Blu-Ray production is supposed to ramp up pretty fast this year.
I've seen DVHS recorders available right now for $300 to $900, so it looks like right now, BluRay is at the high end of the DVHS spectrum, but that could change quickly in the coming year or two.
That's what blue-laser DVDs are for. They can store up to 27gb per side. (54gb for dual layer). Toshiba and NEC are even proposing a blue laser standard that reuses existing DVD manufacturing technologies (for minimal transition costs), that will allow for 20gb rewritables, supposedly available sometime this year.
Actually, the Skyline is available in the states right now, as the Infiniti G35.
Part of the reason japan doesn't import it's cars here, is because the US, actually has some of the most stringent regulations when it comes to safety/emissions equipment. The R34 skyline wasn't imported into the US, because Nissan said that to convert the right hand drive skyline to a left hand drive model wasn't possible, because the necessary emissions equipment required in the US wouldn't fit on the opposite side of the engine compartment. It couldn't be relocated, unless the engine was redesigned either.
The Euro E36 M3 was only 240hp in the states and 280hp in Europe, because the 280hp EuroM3 didn't pass US emissions.
Some manufacturers also claimed not to import their supercars, becuase the US doesn't have low-sulfer gasoline yet, so it supposedly wouldn't work correctly.
Now lets look at the Holden Commodore which was imported into the states as the Pontiac GTO. You'll notice that the aussie version has a 14 cubic foot trunk, but the US version only has a 7 cubic foot trunk. It's because US safety regultions required relocation of the fuel tank, which ate up the trunk space. The aussie fuel tank is in the back under the bumper.
I'm actually more pissed at how the government funds drug research, and when the new drug is created, that private company gets to keep the patent... So the general public is then forced to pay out the wazoo for this new lifesaving drug, even though we fronted much of the money to research it.
