Drive by wire?

[BobsTrail]

I think the throttle control is not linked to the pedal but is sofrware controlled. I was on a freeway doing about 60 in Select shift 5. I pushed it full to do a pass and it dropped down to 2nd or 3rd gear and reveved up over 5k. I let off the skinny pedal and it stayed up at 5k for a second or two before dropping down. I felt like it was doing a runaway acceleration. I did not try it again, the high rev sound was scary.

A one time glitch or has anyone noticed this?

Factory mats in garage and Huskyliner appear to be in place.

If you're in a lower gear at high speed, you DO realize that the revs are going to be higher whether you're on the "skinny pedal" or not, right?

Toyotas don't do runaway acceleration.

Um, yes it is linked to the pedal, that's why it downshifted when you floored it. When you floor it, it will downshift as many gears as is appropriate for your current road speed, up to near red line. If you let off the throttle, it will hold that low gear for a few seconds in anticipation of you again wanting to accelerate quickly, which is much better than it shifting back to 5th and having to downshift again if you want to accelerate quickly.

That's exactly how it behaved except it went down one gear too low and could not accelerate. Sounds like I should have given it time to upshift.

I don't want to be a dick, but "high rev sound was scary"? This is a little ridiculous. Take your 4Runner out to an empty road and floor it, over and over again, then jam the breaks a bunch. Learn how the engine sounds, how the transmission reacts and what the breaks feel like. Loud noises, high revs, and the transmission holding gears are all totally normal. It's a machine, not an Asian school girl.

Yea, the entire drive train is a little awkward in these trucks. They hesitate to downshift initially and then they sometimes go to a gear where there is simply no speed to gain or give some very harsh acceleration when you did not really want that much . Then it shifts and kills the timing and sort of stumbles......

Overall bad design, but they do some of this BS for reliability. It is what it is.....

I would describe the throttle as a very gradual analog device up to 3/4 or so, then it is pretty much an on off switch. Maybe they drive this way in Japan LOL

I thought you drive-by-wire and vehicle stability control went hand in hand. You can't have the computer applying the brakes if the gas is still on.

When I say drive-by-wire, or anybody else, I mean electronics, not a cable hooked up to the pedal.

then jam the breaks a bunch.

Mine does not have breaks, it has brakes.

Actually the newer Toyotas and those that have undergone the BST Campaign WILL kill the engine to idle if the brake pedal is held while accelerating for too long.

Am I the only one aroused by engine noise?

I love the smell of a diesel in the morning. :whip2:

 

[sandcrawler]

i always find it weird when folks complain about the "diesel note" of the 1GR-FE.
apart from its reliability, that's, like, my favorite thing

Burrrn :flame:

 

[555R]

the drive by wire is weird...dont try to left foot brake while on the gas as it completely shuts off the throttle...makes for an interesting deceleration. i found out by accident and hit the brake by mistake when i dropped my red bull down there

 

[ejgroth2620]

So are you confirming the newer 4Runners have "drive by wire", aka ETS (electronic throttle system)?

Yes it is drive by wire. Have a look under the dash and see where the wiring harness plugs into the top of the accelerator pedal.
