Is it a dog?

Lol! I hope they don't actually think it takes time off their 0 to 60 or 1/4 mile times.

 

Haha. You got me curious! It’s more like ten blinks.

 

I have a niece who was a track star. She had several national records in mid-distance runs and on relay teams. Full ride to OSU! We asked if she was going to try out for the Los Angeles Olympics and she told us "No" because she was a 1/10th of a second to slow. Not many of us are going to race 4Runners at Lion's Drag Strip or race at Indy or Le Mans. I proved everything I had to prove, to myself and others. I'm old and don't need 750 hp Mustangs that spend more time up on hoists getting worked on. My "Blue Beast" will still pass most cars on Stephens Pass or Loveland Pass. That's all I need it to do. If you consider that a "dog", fine. To me, a dog was my '82 diesel Scout that wouldn't pass a desert tortoise without downshifting or my FJ40 that wouldn't go faster than 60 mph (uphill, downhill or up the side of a tree).

 

Depends on when you start the clock. Is it when the tires first start to move? Or when the foot first stomps the pedal?

 

Either way, makes no difference. Those devices only amplify the signal from the pedal to the computer. If you stomp the pedal, it doesn't matter if you have one or not.

 

Sorry, BG, but I think it does make a difference. The Pedal Commander (or Sprint Booster) doesn’t make the throttle react faster than your foot. It removes a programmed delay that forces the throttle to open slower than your foot. The throttle response controllers allow the throttle to get to 100% open more quickly.

 

Wasn't a full tank, but this was what I got driving in Moab that day shuttling our mountain bikes around. This thing was amazing though, we drove from SLC to Moab, then drove around for most of the week before needing fuel again. I actually really enjoyed driving it. I often think to myself that I'd like to have a Burb. I wouldn't have got this generation though, the GMT800 generation is kind of the sweet spot (IMO) for reliability and comfort.

 

Unless that is an OEM Toyota pedal assembly and a Toyota throttle body being controlled by a Toyota ECU, that really doesn't prove anything.

I have heard people say that it removes the delay. But, I don't see how that's possible. Here's why:

If the delay is created by the ECU, then it is created after the signal reaches the ECU. There's no way for a throttle manipulation device to change that. Also, if the delay is created by the pedal, then that delay is applied before the signal reaches the device.

So, I'm not really sold by some guy playing around with some generic pedal and some generic throttle body on a table at an event where he is trying to sell a product.

If I saw a demonstration where someone showed the actual response of a Toyota pedal with a Toyota throttle body, I might buy into it.

I'm not saying they aren't nice products. Obviously, everyone who has them thinks they are great. I just have a hard time believing you can remove a programmed delay from the throttle response without doing actual tuning.

 

Yeah, foot to the floor it doesn't make a difference. At part throttle is where you notice it. With mine, I noticed that it is less hesitant to downshift, so the downshifts seem more seamless, and you don't lose as much speed on hills.

On my stock pedal I notice a dead spot kind of in the middle of the travel, that you have to push through in order to get it to downshift. Running a throttle controller device seems to eliminate that.

 

The signal sent from the pedal to the ECU is modified.

 

Well, yeah. But, I still don't see how it can send a signal beyond full throttle.

My understanding was that the delayed response of the plenum was programmed into the ECU. If that's the case, nothing that device does can change it. And, if that delayed response is coming from the pedal, then it is created before the signal reaches the pedal commander.

So, I still don't believe those devices can make the plenum open faster than I can make it open by stomping the pedal to the floorboard. And, I don't tend to believe some guy trying to sell a product at a booth at some auto show.

 

That demo shows nothing. There’s no ECU in the mix.

Also you can stomp on it for the same effect. I have a PC and have had it off for a month. I don’t miss it.

 

How it does it exactly... Witchcraft.

Joking aside, it definitely does help minimize that delay in throttle response. I was skeptical at first too until I decided to just try it myself. pre-PC, it wouldn't matter how fast I stomped that foot to the floor, there would be what seemed like full second delay between that and when the car started moving. Now it's pretty much instantaneous. My 2 cents...

 

Conceptual illustration. Not accurate, but correct in essentials.

 

I'm not sure what you're trying to illustrate. We all (or, at least most of us, I assume) understand that the pedal commander manipulates the signal from the throttle pedal to the ECU.

But, I see no reason to believe that it can cause the plenum to open faster than if you just slam the gas to the floor. I'm pretty sure that would require actual tuning of the ECU, which that device does not do.

 

Never mind. I like you too much to alienate you over something as trivial as this.

 

You're not going to alienate me.

I understand what those things do.

But, some folks seem convinced that by manipulating the signal from the pedal to the ECU, it can make the ECU do things it's not otherwise capable of, which I don't believe.
