As I never heard about such a "tuning" thing like an enhanced throttle control I seek your advice here.
What for is the device and how does it work? Obviously it isn´t an typical chip tuning with more torque and power.
But how does it work and what would be the reason the manufacturers don´t build their cars this way from the start?
Or to put it in other words. Where are the downfalls?
What you buy in a modern vehicle is something setup for optimal/general response + economy.
The factory could theoretically set it up (tell the computer (via your right foot pressure/movement) to accelerate with the slightest of pressure/movement. But it's not a Lambo!
That setup would be a problem in stop-start traffic , and offroad where you would be leaping all over the place , especially when you hit a bump.
But an higher than stock response is practically useful under some circumstances, and also enjoyable if you are a sporty driver.
The TC can also be set to "slow" . That gives more control when you are offroad or reversing, reversing up to a trailer etc etc.
So a TC gives you multiple options , factory mode , valet mode (safety factor), offroad control mode , economy mode , launch mode (traffic light hero) and a higher response mode for towing responsiveness , overtaking.
You select the mode you need for whatever situation you are in.
If you know "Sports" / "Sports plus" mode on some cars , that is what you can achieve with the high response settings. Without the change in suspension settings though, it's all analog underpinnings!
No downfalls if you preselect what you need for the upcoming driving situation.
It does not change turbo lag , fuel settings , anything other than the way the vehicle responds to your right foot pressure/movement.
It cannot harm your engine.
Yes it could be fitted ex factory , but perhaps there are safety factors , end user errors of judgement etc. You wouldn't trust most motoring journalists to be able to operate it ....
And you'd pay for the privilege of having it fitted.
