Sport Button thoughts.

[shimmy]

If the sport button, when on,makes the car more twitchy at low revs surely at high revs it makes it less twitchy as surely it must be less responsive to pedal movement (at high revs)

Your thoughts please :supz:

At wide open throttle its the same whether on or off.

In sport, the pedal movement % increases the throttle open % compared to sport off.

It only makes the car more twitchy because most people are too agressive with the inputs. If you alter your input of pedal movement when sport is on and press the pedal slower and more progressively then it will take off the same as when sport not on.

On my old M3 and M5, which I guess both have a similar set-up, it always felt like the pedal:throttle opening curve had just been shortened.

Which, in turn, meant that the throttle was fully open before the pedal reached the stops. I never liked the throttle response in Sport mode - it always felt too twitchy and I don't see why that is better - if I wanted full throttle, quickly, I'd push the pedal down quickly. Irritatingly, the button also did various other things that I liked (steering weight etc), so I used to put up with the throttle response.

The CSL may be different - can't wait to find out!

CSL sport only alters throttle. Thats it.

Yes but more twitchy low revs sport on because you are playing with more throttle with less pedal movement.....meaning at high revs sport on you'll be playing with less throttle change with more pedal movement

Thanks. Does that include changing the behaviour of the airbox intake flap and hence the induction response/note at lower revs?

It does, but that will probably break anyway:hahaha:

Do you really give a shit:smt038:smokin:


I think it will have a ceiling, wherein the difference is non existant between sport on/off. Say 70% pedal movement above is always equal to throttle opening, regardless of sport on/off.

It's a rectangular, black plastic button. End of.

Nothing to do with high revs and low revs?

Shim I have lots of Sport Button thoughts, usually day dreaming at work! :drool: Oh by the way got the job and start on the 27th June :smt023
