    Anyone know what might be causing a spike in the turbo guage/turbo on a WRX? My buddy has been experiencing spiking on the high RPMs and bogging. We are suspecting a bad wastegate spring, but of course the dealer says "you shouldn't be pulling the car to near redline in 2nd gear" and "it doesn't do that for us under normal driving conditions" and "You kids need to stop treating these cars as race cars, they are just sedans" That is the great service dept. at Morristown subaru in NJ. I'll probably refer him to patti after the district rep meets with him on the 29th. If they give him the same line of BS.

    We've got a great Rep. in that area, so hopefully it will be okay.

    I figure I'll let the system work the way it's supposed to and we'll take it from there if it doesn't work out. It's amazing how dealers almost universally give the same answers, as if reading from a script. Too bad there is no way to hold them accountable to SOA via contracts or franchise agreements or something. I know it's hard for SOA to control the service departments, so I don't blame them. :(

    Although I've heard that term may times, I really don't know what it means... I'm assuming it is electronic steering?

    I'm all for anything that makes life (or driving) better. If this is one of those features, go for it.

    Yes, meaning no steering rack at all. Not an electronic steering pump, I mean the entire steering mechanism. That would certainly allow for an easier LHD to RHD swap.

    The Passat has a drive-by-wire throttle. The stuff is trickling onto cars.

    I'm OK with it as long as they leave the feedback.

    You mean having servos actually control the steering? I don't think we'll see that for some time. It's one of those safety issues that most companies don't want to get mixed up with. I don't think we'll see brake-by-wire anytime too soon for the same reasons.

    I think the early systems will have a mechanical backup, probably by law.

    But think about it - airplanes have used the technology for decades.

    partially drive-by-wire? I know it has some sort of strange lever that replaces the traditional gear shift. Everything I've read about it suggests that it's unlike driving any conventional car.

    I can't get over the hunch-back, though. I think they swung for the fences and really struck out this time.

    But people really grade on a curve when it has that little propellor badge on the hood.

    I sent him a PM with a bunch of tips on how to deal with his problem. I've met the district rep. and he's a real good guy.

    Patti - you actually met him at the Philly auto show.

    I doubt steer-by-wire will come anytime soon. Even if it did, I suspect the loss of road feel would be horrible.

    It'd feel like a video game, basically.

    I think we'll see throttle-by-wire first, then brake-by-wire, because steering is probably where natural feedback matters most.

    Is pretty common now. GM uses it, Isuzu trucks have used it for about 3 years, VW? and a bunch of others IIRC. I agree brake by wire would come before steering by wire, it's easier to put in a mechanical backup system for the brakes than the steering.

    the Honda S2000 has electric power steering.

    Bob
  • paisanpaisan Posts: 21,181
    Bob, would that be electric driven pump or electric servos? The only electric system I'm familiar with is the one in the XT6 which has an electric motor running a pump for the PS, it is nicely placed back on the firewall, and doesn't burn up power from the engine, but trying to repair it is not fun.

    -mike

    Electric PS just means the assistance is electric and not hydraulic. You still have a steering rack and pinion, and all the associated hardware.

    But they say it consumes less energy, so it's likely that it'll appear before steer-by-wire does. I think Saturn uses it, and paisan's XT has it.

    The XT6 is hydrolic. The only difference is that it uses an electric pump to pressurize the PS lines, rather than a mechanically driven pump from the motor.

    Sounds good, replace "hydraulic" with "mechanical" in my post, in that case.

    Have any of you ever paid for an annual check-up for an aircraft? One of the reasons that it makes sense for fly-by-wire is the enormous distances between control surfaces and the controls in a large airplane, combined with the enormous amounts of maintenance and inspections and redundancy they have built in. All these factors combine to make the likelyhood of automobile steering and braking being totally electronic a distant, expensive, and maintenance-prone prospect.

    Trivia: In the case of the F-16, which was the first production fly-by-wire aircraft, I believe, the aircraft is inherently unstable. Thus the computer(s) fly the aircraft, and the stick just provides input to the computer to change the direction of flight. The original flight-control computers on it were actually analog, and IIRC, there were four of them running in parallel on each aircraft for redundancy.
    FWIW,

    Well, they've used steer by wire for the rear wheels in the Prelude and MX6 in the past, and I've never heard reports of problems with those systems.

    Plus, cars operate in much more controlled environments than air planes.
