I dunno but it does make tip in way WAY faster...so it might help ET some...
Nope. It's like a "feel good" tune. It feels good to the driver who is moving his foot, but the passenger and the 60' number on the timeslip never notice a difference.
This is not a Vendor thread. Please do not advertise here.
There is no, I repeat no vendor worse at crashing a thread then the CoWboy. He does it when he feels the most threatened which is always. And unlike other vendors, he bashes ALL vendors competing with him for your hard earned $$$.

I would propose that it should make at least a small difference; it might be immeasurable in practice. Electricity flows much faster than physically moving your foot further on the accelerator, so if you reach a desired throttle position 30 milliseconds sooner with a throttle controller the car is moving at the desired pace sooner. It probably doesn't translate into a meaningful drop in et but should be there in reality.

Oh! That's the guy that was adamant about the corvette tax not existing and being some big hoax. hahahaha! Your company is one of the MAIN OFFENDERS. He probably thinks that dealership service departments are great and they also are victim of some grand conspiracy
Although a throttle controller doesn't give the car more power, it seems it can enhance the driving experience, especially if your are driving through canyons and want more throttle sensitivity. Much like a short throw shifter doesn't give the car more power, just better control. It all about dialing it in to suit your driving style. I already have a Z06 exhaust and a tune but the throttle does lag a bit. It looks like the Vitesse brand wins the poll and I think Ill order one today. Thanks to everyone who participated in the poll.

Hey you, NutSac!. Well, I got nothin more, just never had the opportunity to say that on the forum before.

Here is what I know...I 've owned a car with it....You get more throttle with less movement of the foot and pedal...those movements no matter what take time and less time time is usually quicker ET.. If I can get 100% throttle two inches quicker than you then I'm ahead in time....or burning rubber sooner.
Seriously... the weirdest thing was I got a little better MPG because i was so aware of any pedal movement I learned to be softer on the pedal...

That's all actually true and you will pick up mpg on the highway once you learn how to drive the car.
OK, I placed my order for the Vitesse throttle controller. Hopefully, I'll get it by next week so I can see what all you guys are talking about... Vroom!

Since the 60' clocks measure to the closest 1,000th of a second, aka millisecond, and the timer doesn't start until the beam is restored, the tire diameter or how deep you stage can make more difference than the speed of your foot movement over a shorter distance.
BTW, throttle controllers don't change the acceleration/deceleration ramp rates of the stepper motor.

But I paid all that money. Surely it must do something. I'm sure I can feel it doing something. If I couldn't feel it, then I would have wasted my money. Yes. I'm sure I can feel it.

Deny it all you want. They definitely change the way the car drives, whether you think they do or not. I was of your opinion until I decided I didn't stand to lose much if I didn't like it. It's still on my car 4 years later and is still one of the most enjoyable mods I have done. So on this we will simply agree to disagree, although I have to believe you have never driven a car and tried the different settings out. I could understand if you said you didn't like it, but not that they don't do anything.
I don't currently have a dog in this fight but I've been watching the thread with interest. What I can tell you is I spent over 20 years of my life racing cars professionally and simple changes like remapping throttle response can often have a drastic effect on lowering lap times, or not.
I would love to see a shootout between the stock settings and the different controllers, but that will probably not happen. I'd also really be interested in hearing from anyone that has spent a track day with and without a control to hear your thoughts and lap times.
Anyhoo.... no matter what the $200 throttle controller actually does if it puts a big smile on your face every time you drive the car that's a cheap price to pay in my humble opinion.

Oh, it does something alright, but it's not changing the acceleration or deceleration ramps of the stepper motor. The throttle plate does not move from a dead stop at full speed, nor does it slam to a stop either direction.
What throttle controllers do, is electronically change the relationship between the distance of available foot pedal movement and the degree of throttle plate rotation. The stock curve is a slow progression to obtain smooth foot control at low engine speeds. A curve can be created to be a lower or higher progression or simply a linear progression. A linear rheostat is like your radio volume control or a light dimmer switch.
Linear is like cars with 1 or 2 barrel carbs that used a steel rod had, where you can change the rate of progression by moving the location of the connection on the bellcrank. 4 barrel and multi-carb cars slowed the rate by opening additional throttle plates progressively using mechanical or vacuum methods. Most all carbs on auto trans cars had a diaphragm to slow the throttle plate from slamming shut when the pedal was lifted. When cars with cable throttles became the norm, a progressive system was possible by using an eccentric on the throttle shaft. Electronics created far more choices than the old mechanical systems.
BTW, I have driven cars with the highly selectable Vitesse system and the limited Booster type. If I had a need for more control than my foot can provide, the Vitesse would be my choice, since it has slower than stock progression (aka delayed) user choices in limited traction situations.

I 100% understand exactly what they do, as do you. I am a degreed engineer with an electrical engineering background and I worked as a quality engineer/manager in tier one OEM supplier manufacturing for over 20 years. The throttle controller allows me to tailor the throttle exactly to my liking, which is more linear instead of the stock 50% pedal movement gives 20% actual throttle application. I have seen the graphs of the exponential curve (half parabola?) of the OEM throttle mapping.
Aggressive OEM throttle application is the reason some cars, like the 4 cylinder 2013 Subaru Outback I previously owned, feel much peppier than they really are.
I put the Vitesse on it's most delayed setting shortly after I bought it, and it feels like you are dragging a boat anchor. If I ever had to Valet park, that's the setting I would leave them with!
