Throttle Controller Dangers?

[zkattac]

Im tempted to get one, but there has to be a reason there's a delay between us pushing the pedal and the motor responding. Maybe it's calculating air, fuel, etc needed? And what about if you have a tune on your engine and transmission could the instant throttle response mess with the tune?
Like I'm said im tempted but I'd like to hear some definitive information to convince me.

How much more information do you want to see? Like any other mod you have to weigh the choices to do it or not. What about getting it tuned? Maybe there is danger in doing that? What about motor work like replacing the cam? Air intake? Tires? Gears? All of those are performance mods that people do to change the way the car responds, and the VTC is just another one of those mods.

I haven't tried the controller myself, but keep in mind that the factory tuning is done with the general public in mind. That tip-in on the throttle is because you don't want every yahoo with a V8 and a heavy foot to have the kind of power on tap that comes from the factory in modern performance cars.

There are also concerns with stress on driveline parts, etc. There are a lot of reasons why the car is tuned the way it is from the factory but you could make the same argument against any mod.

I've seen some interesting counterpoints against the use of the throttle controller. I'm holding off for now, seeing how they work out for other folks.

Take the precautions necessary to protect a car, maintain oil changes, and don't push a car to its limits all the time. My rationale for my mods. I'll keep smiling until my reasoning fails me

My tuner tells me GM has some built in safety parameters built into the OS surrounding the TB opening rate (I'm paraphrasing him). What I took his comments to mean were it prevents you from getting sideways. Others have mentioned that these TBs don't flow well off idle so I imagine the DTC just opens the blade wider faster. The down side I see would be the blade being open too far to early and hurting performance, sort of like putting a Holley Dominator on a street small block. It would actually lower the velocity of the intake charge, but based on user's feedback, I doubt there is a lot of that going on.

With the Vitesse controller you have 9 settings to choose from that increase throttle response, you can experiment with it and see what setting you feel most comfortable with in everyday driving. I usually run my V6 on SP5. It takes the sluggish feeling out without being too fast making it dangerous.
Mostly the factory tune is for emissions and fuel mileage. I really doubt it's for reliability reasons. These cars are pretty reliable at stock HP and torque. Adding power is when I would start worrying about reliability.
Again I say find a setting you are comfortable with for everyday driving. Then when you want to play you can bump it up higher if you want.

As I've stated in several other VTC threads, my theory is the factory lag in response (and it's only like a second) is there to allow the computer to analyze the traction control and stabilitrack requirements based on the anticipated acceleration depending on how much the go-pedal is being mashed. If there was no lag, a hard start would spin the tires immediately... before the TC/ST system could react to prevent it. That is the only potential "danger" of the VTC, but it's one of those driver responsibilities that one must exercise.

But it's just my theory.

I used the "computer" in my head to make those calculations. When we had
Mechanical throttle linkage , it didn't seem to be a problem then.

I was trying to experiment with the launch control at the track just to see how it would do, but it seems to be too much a PITA to deal with. Then when I use a 26" DR, all the nannies hate it. Some things are better left to the end user.

dude just dont get it ,its not for you .....

Just remember....no modification is dangerous. With that being said, it is the person behind the wheel and their foot on the gas peddle, and their ability, or lack there of, that can be dangerous. I just installed the VTC and love it. No company would be allowed to make a dangerous product. Ever modification is done to enhance the vehicle. I can put 1000 hp in a car and it will do NOTHING until I turn the key and mash the gas....how I handle it is up to me. Just my two cents.

That's not at all true.

I 2nd that. Everyone is looking to make a dollar but reputable and reliable companies don't intentionally make dangerous parts for the sake of their business...and for some, morality reasons

While I agree with No company would be allowed to make a dangerous product being false, but most companies are not INTENTIONALLY going to create a product that will break/harm/hurt your vehicle or yourself. It isn't exactly good business to break the device it is put on.

Then again people are shady individuals. Businesses are just collections of these people.
