Does anyone knows the exact differences in the normal vs the sport mode or where can i find this info?

Thank you all

 

I haven't checked the owners manual but I'm sure some info is in there..

Sport button changes the throttle map and I'm guessing now VVT timing along with the exhaust bypass valve open/close rpm. It will also sharpen the shift points and delay till a higher rpm

To feel a change, coast at a constant speed with steady throttle.. Now push that sport button.. Should feel the car accelerate and depending on the gear it might downshift if your in D (which you shouldn't be btw unless parking or long distance highway )

 

Thank you--

I was looking for the specific technical data as to the difference in the maps etc...

 

Driver demand pedal Tq stock





Driver demand pedal Tq sport

pedal count on "y" axis and RPM on "x" access. Reads the driver demand torque in N-M.

Hope this helps

 

Great info! Looks like all they do is ramp up the torque earlier in pedal travel for "better throttle response". Similar to that of those SprintBooster pedal devices. Max power levels unchanged

 

Can someone explain that in plain English ?

 

There is a table in the engine computer that is called the throttle map. It translates every millimeter of travel of the accelerator pedal into a certain percentage of throttle opening at the engine intake. A "linear" curve would be one where there is a proportional one-to-one correspondence change. So a 0% pedal you are at 0% throttle opening; 50% pedal = 50% throttle; 100% pedal = 100% throttle, etc.

There are devices out there like the SprintBooster, that fool the computer into thinking the pedal is in a position different than it really is. 0% is still 0% and 100% is still 100% but all other points in between are "tweaked" electronically. By doing this, you can make it so that 10% pedal translates to 15% throttle; 15% pedal = 21% throttle; 20% pedal = 28% throttle, etc.

The result of this is that, for the initial portion of the pedal travel, the throttle opens quicker than it normally would and that makes the car feel more responsive and creates the illusion that the car is faster because pressing the pedal the same amount your foot is used to all of a sudden is converted to a larger throttle opening than before.

On the Vantage, when you press the "Sport" button, the engine switches to a different table that has this same curve-altering behavior as a SprintBooster. So the feature is already built right in to the car and no external device is necessary. Some engine tuners will also modify the values in the throttle map table to make your car feel quicker.

Too much of a good thing, though, can be a problem. If you increase the curve too much, the car starts to feel "twitchy". Just slightly tapping the gas pedal makes the car lunge forward. This makes it more difficult to finesse your speed in situations such as parking where moderate applications of throttle prevent you from lunging into the car ahead of you.

HTH.

 

Thank you very much!!!
