Why I REEEALLY hate this throttle-by-wire crap!!! (YAToyotaThrottle prob)....

[Jeff7181]

Yes, I know how to rock a car out of the snow. I've been driving RWD cars since 1973 in Michigan winters. No slamming needed. Just gentle back and forth. Maybe, my experience is unique seeing my frustration is from my Prius. There is just no way to shift fast enough to rock the car out. The wife got it stuck last year trying to get mail out of the mailbox and the only thing stuck was one tire a little bit in the snow bank. It should have been a cinch, however there was no way to get the engine to to pull it out. As soon as the wheels spun a little, shifting in the other direction meant waiting for the wheel to slow down to almost nothing before the trans would even think about changing gears.

I fail to see how TBW is relevant. You don't even need reverse to rock a car out of snow... all you need is drive and neutral. In fact, unless you're driving an OLD OLD OLD car, I don't think you can even put a modern automatic transmission into reverse unless your foot is on the brake and the car is not moving. I've driven a 1977 Cutlass, a 1987 Lincoln, a 2000 Mitsubishi Mirage, a 2001 Sable and my 2008 Altima Coupe in the snow... NONE of them I've ever gotten stuck in the snow for more than 30 seconds to a minute and I've never used both reverse and drive to rock out of the snow.

my experience in mud (not much snow here) has always been to go forward, quickly brake the wheels, go reverse, rinse and repeat. you don't just need to brake to disable the shift lock, you need to brake to stop the wheels before you ask them to change direction.

2005 Nissan Altimas and 2010 Toyota Corollas can both shift directly from drive to reverse without touching the pedals.

I'll make a video of this tomorrow

Ridiculous piece of shit. The sprint booster just tells the computer you've pressed the throttle down farther. So at 80% of pedal travel, you're at WOT.

idk people tell me it doesn't do that, idk I got to look into it again.

 

[Viperoni]

A lot of people in this thread are forgetting that throttle-cable cars have Idle Air Control valves. I'm sure that the throttle plate closing slower is a bit more effective than an IACV, but after having driven a friend's 07 Civic Si... it's definetely not as much fun.

 

[BassBomb]

mine is fairly laggy at low rpm

otherwise, its ok except the slight pause before it notices you pressed down harder

Think about it for a second, what else could it do? Magically make the electricity go over the lines faster? Change the computer's programming to more quickly open the throttle?

You're unlikely seeing the lag of "electricity going through the lines" but what you may be seeing is lag from the computer. The inputs are nearly instantaneous but the computer reacting to them are not. It's also possible that the computer isn't lagging as so much as reacting slowly because it's trying not to create too much unburned fuel in the exhaust or something..

You didn't even read what I was talking about.

I was being sarcastic asking him how else the sprintbooster could work in any way other that it "lying" to the computer about how far you depressed the pedal.

oh, yeah I see what you're talking about now.. yeah it's unlikely they're re-programming the computer but just lying to it which is what most of these ad-hoc pieces of hardware do..

The worst ones are the "power chips" which are just resistors that lie to the computer about the MAF readings and lean the car out a little. Best case you get a 1-2% gain, worst case you seriously screw up the motor for lack of fueling.

I can do that in my car too...in fact I did it with my dad in the car at 60mph to prove to him that my car wouldn't explode at speed. E-CVT FTW

The LS1 (cable) in my Camaro and the LS2 (electronic) in my C6/GTO feel exactly the same. It's all in your head.

Not true. The PCM legitimately (purposely) slows the throttle response on many cars, including your LS2 and my LNF. Have you tuned the C6/GTO? You'd be surprised how much more responsive it gets that you haven't noticed before.

 

[Fenixgoon]

the 1.8T (cable) in my VW Passat feels entirely different than the various drive by wire cars (Chrysler T&C, Hyundai Santa Fe, and Nissan Maxima/Altima) I've driven.

THis is what I said, but my friend thinks it something else thats amazing.

It won "Best new Product" at SEMA so it has to be something good.

But if it in fact just does what you and I think, then its way over priced.


Its suppose to give the Cable throttle feel.

 

[ultimatebob]

Throttle by wire is REALLY fun when the gas position sensor malfunctions, causing the throttle to get stuck wide open on some back country road.

What I loved even more was how Audi customer service tried to blame the malfunction on a loose floor mat, and then stuck with me with the repair bill... just like Toyota is doing now :|

There's a backup system in my Jeep if the first one fails, It will switch to the backup system and let you limp home with the ETC light on.

 

[exar333]

Well ya.. obviously it feels different. It didnt really take long to get used to though.

This sounds like a quote right out of a Trojan commerical.

Anyway, back on topic: I agree that you have to be "choosy" on getting a car with a good DBW system. Some leave you "unfulfilled" and the lag is really annoying. :awe:

 

[JeffreyLebowski]

I hate throttle by wire. My 06 Silverado has it and I can tell the difference between it and my old Chevy C/K 1500 with a cable linkage to the TBI throttle body.
My truck and the POS Toyota Sienna we have both have inconsistant throttle response due to the electronic throttle.
That's why I much rather drive my 3rd gen T/A as it has a proper cable linkage.

 

[yh125d]

My car has 1/2" of throttle travel before it revs up at all. Makes it odd taking off (man). WTB cable

 

[fbrdphreak]

A buddy of mine has a Legacy GT with throttle-by-wire and he didn't like it either. My Tundra, same thing...it does feel different but you'll get used to it.

My Legacy GT has TBW/ETC, but I don't notice any lag at all. My 06 GTO though had very noticeable lag.

 

[lobbyone]

I really dislike the TBW, but I got used to it.

 

[JulesMaximus]

Uhhh what?

Fleabag has been inflating his brain to sidewall again.

 

[DivideBYZero]

I find it odd that people are complaining about throttle response when it could just be that your motor of choice would have the same response whether it were electronic, cable or a barrel of monkeys.
