Well I love the Sport button :)

[M@r]{]

I meant to post this up the other day. I've totally ignored this since buying the car, just figured it wasn't a big deal Throttle Response. But the other day on the way home via some tempting looking country roads I switched it on. It does really make a difference, I found it made you want to drive quicker, hard to explain really, made the car feel quicker?

And where I think it helps a lot is when you're trying to do a bit of heel and toe. I'm normally ok jumping in a car I don't know and doing it, but for some reason I've been struggling in the Z. But this makes it easier. I think what it is is the difference in height between the brake pedal and acc. pedal. In non Sport mode you have to press the acc. pedal down quite far to get the revs up to match, and this causes you to push down on the brake harder (using the same foot to do both obviously) But with Sport on you don't have to press the acc. pedal down as far to match the revs therefore making it easier?

Anyway having read a lot of people saying they don't like or don't see the point in it I thought I'd put a positive point of view across (and also as I'm currently on a road to hate with these German pieces of crap I'm desperately trying to keep a positive mind )

That is all, carry on

Do you think it uses more fuel with Sport button pressed?

Depends how you look at it. On its own no, the Sport button wouldn't use more fuel. However with it selected you are going to be accelerating harder which will use more fuel? Thats my understanding anyway.

And having covered a 120 mile trip from Telford consisting of 80 miles motorway sitting at 70-75mph and the remaining 40 driving through town and on country roads with the Sport Button on, the OBD said I averaged just over 29mpg which I thought was very reasonable 8)

People really don't believe how economically these motors are! Ive been getting 26 average with town driving! Dont be disheartened! Did you get the bits sorted in the end?? Sometimes they need a bit of love then it will start appreciating it .

Maybe the previous owner wasn't too kind to it.

My sport button is race gas/meth mode
Also ess added sport button memory so if i turn it on it stays on, and vice versa.

Exactly as I've said every time this discussion has come up The same is true when double-declutching, and with rapid upshifts at maximum attack. The muted response of the first part of throttle pedal travel is very frustrating when driving properly :evil:

In fact, even smooth, gentle pulling away in traffic is easier in sport mode (with a warm engine at least) as a small amount of pedal pressure leads to a predictable rise in engine revs rather than nothing at all.

I press the sport button before I start the engine and don't feel the need to turn it off.

Essentially:

[zero pedal press in sport mode] = [zero pedal press no sport mode] = [zero throttle opening]

[full pedal press in sport mode] = [full pedal press no sport mode] = [full throttle opening]

[required throttle opening for a given rate of acceleration in sport mode] = [required throttle opening for a given rate of acceleration no sport mode]

[throttle opening in response to 10% pedal press in sport mode] > [throttle opening in response to 10% pedal press no sport mode]

Therefore

[required pedal press for a given rate of acceleration in sport mode] < [required pedal press for a given rate of acceleration no sport mode]



A given rate of acceleration in either mode uses an equal amount of fuel

However, a given amount of pedal press will give a greater amount of throttle opening in sport mode, with a consequent faster rate of acceleration in response to that amount of pedal travel. This will burn more fuel.

Sport mode just changes the throttle map to one with no toe phase and a steeper gradient in the early part, but the same start and end points (throttle fully closed, throttle fully open)

Not sure I agree -- if driving "properly' the only time the throttle pedal shouldn't be buried in the floor is when you're on the brakes.

Cornering on a track must be fun in your car, if a little slower than everyone else :?

What do you mean? I'm sure he corners faster than anyone...it's just that every corner is at least 360 degrees, some 2 or 3 times that

 

[Darren Slone]

On our meet today had the sport button on all the time, much better IMO , only managed 20 mpg not the higher figure others are getting :?

It was amazing though!!!!!

So do I
with it activated it takes off like a startled rat (auto)
