    Ok, I see what you mean about hot wire based MAS. Even my old '94 Ranger has one. I remember it detonating at high load when it got dirty. Now after reading up on how the closed loop systems with hot wire based MAS work, I know exactly why it was detonating.

    I was under the impression that the volume of air coming in remained constant.

    You didn't have to be an asshole about it.

    Denser air has more oxygen, so less air is allowed into the cylinder.

    My apologies if I was wrong on that point. I guess "rich" was the wrong term, as it implies that there is an imbalance in the fuel/air ratio. What I meant is that higher oxygen content in the air require more fuel to bring the FA ratio into spec.

    I assumed that the volume of air taken into the engine remained constant, relative to the temperature, and that the engine adjusted the fuel rate to maintain the proper ratio, and reading up on MAS I see that wire based ones can detect air density differences.

    Anyhow, the losses we all see in cold weather are probably more do to higher friction, rolling resistance and longer time to warm up.

    I don't get the point of your little lesson. I was assuming we all were aware of how modern engines dynamically adjusted the rate of fuel flow.

    The sensor detects the amount of unburned oxygen in the exhaust, and thus the fuel mixture ratio. The engine computer modifies the mixture based on the sensor's output;

    Exactly. This illustrates my point. Denser air has more oxygen, which causes the engine to inject more fuel into the mix.

    Modern engines account for this and attempt to keep the intake air temperature within a certain range, but when the outside air temperature swings between temperatures of 100 degrees in the summer and 20 degrees in the winter, as it does here, the intake air temperature ends up varying wildly.

    Between the summer and winter extremes, the intake air temperature (as reported by my cars computer) varies by at least 60 degrees (F).

    I'm not sure how much of an effect this has on overall fuel economy, but it is a factor.

  7. Re:10% Ethanol on Is E85 Dead Now? · · Score: 4, Informative

    It's not the ethanol that's sapping your fuel economy, it's the climate. Cold air is denser, and causes the engine to run richer, i.e., inject more fuel into the engine. This gives you a bit more power, but at the expense of fuel efficiency.

    The denser air also provides more wind resistance.

    Also, your car takes much longer to warm up in the winter, and until the car reaches normal operating temperature, it runs extremely rich.

    Wet and/or icy road conditions probably also sap efficiency too.

    Nonsense.

    First of all, this guy explained that it was "slack space" which he used to recover data. He was talking about sectors that are deallocated when you delete a file, something that anyone can recover files from.

    Second, those hard drive platters from the space shuttle were not written over with zeros, or encrypted strong crypto. And there is NO WAY the platters were heated to 3500 degrees. The patters would have been completely destroyed by that much heat. I just Googled and found the story on the hard drives. As I suspected, the platters were not damaged that badly.

    I saw a forensic expert that works for local law enforcement give a presentation for a local community college "intro to computers" class awhile back. 90% of what he told them was bullshit. He told them, that once they saved a file to their hard drive there was no way they could really delete it and that he could always recover it. He went on and on, belaboring the point that there was no way anyone could ever hide anything from him. I was working on a computer in the class, getting it ready for an upcoming engineering class in the same room, and didn't want to start anything so I just shut up, but I mentioned to the instructor and the class members later that the guy was full of shit.

    It kind of disheartening that a moron like that qualifies as an expert witness for law enforcement.

    I bought a trip computer (a cheapy "ultra gauge") and has turned out to be very accurate with calibration. Without any calibration, it was a little off, but it allows you to calibrate it by entering in the actual gas used vs the recorded gas used when you fill up. I use the "same station, same pump" method too.

    The big benefit to the trip computer has been the feedback it gives me. It taught me is that my '04 Sonata's computer is brain-dead; it doesn't intelligently cut off the fuel when you coast, so putting the car in neutral uses much less fuel when coasting to a stop. I get an extra 5-8 MPG over EPA as a result of the what the trip computer has taught me.

    My '08 Honda Pilot on the other hand has a very well programmed computer. No matter how carefully I drove it, I could never eek out more than one or two extra MPG out of it.

    This is quite plausible. With my phone, the Epic 4G, a local root exploit was available for use for at least 6 months before they finally released the phone's Gingerbread update recently. While it was useful as a one-click-root solution, it could have also been useful as a tool for malware authors to embed their crap into the ROM.

    Now, with the Gingerbread ROMS, new kernel exploits are already being discovered and put to use. I used one to root my wife's Epic 4G Touch, which was only released in November.

    Undoubtedly the kernel exploit will linger for many, many months until Samsung releases a new ROM update.

    That differs from Android, in that phones that are only a few months old don't get Android updates - certainly not promptly, and often not at all.

    You can't do an one to one comparison of iPhone to Android. iPhone is a premium product which ignores the low-end market, while Android devices vary from bare bones, entry level, barely-better-than-feature-phone phones to super high-end devices that compare to exceed the latest iPhone hardware.
