SPORT Button: What does it do for a E85 M Roadster??

[suprtran]

On my E46 M3, the Sport button very noticeably changes the throttle response of the car. However, on my E85 M Roadster, pressing the Sport button provides no change from stock. Is there something wrong here? What exactly does activating the Sport button do on our E85 Ms?

It should be noticeable. It's noticeable on my M Coupe. The throttle is immediately more sensitive. I'm talking immediately.

Changes Gas Pedal Response and during cruise control it gets up to speed faster.

Waste of money to even invest into that. I never use it

By not experiencing any change or increase in throttle sensitivity, I have a feeling that my M might have aftermarket software installed that puts it into Sport mode full-time. Does anyone know if such software exist for this car? Car is a 2006 that was purchased 1 week ago @ 20k miles.

On the Z4M, you must release the throttle one time fully, after pressing the Sport button, before the quicker throttle profile kicks in. I believe that the M3 is different in this respect--on a constant throttle pedal, the M3 speeds up immediately when Sport is pressed. (I read that about the M3 somewhere, haven't experienced this myself.). Once Sport is active on the Z4M, the car WILL slow immediately if you disengage it and hold the pedal steady; it's different going out vs. coming in...

All that said, for me Sport makes the car undrivable. Way too abrupt and hard to modulate when you want things to be smooth on corner exits at the traction limit. It does, however, make heel-toe easier.

should work?

i used to turn sport mode on in my ZCP-M when i was bored in traffic. it's supid imho. i wish the sport button was like that for the RS4....change of exhaust note.

QFT.

Yes, but when u use it all the time and get used to it... Going back to non-sport mode feels like ur wearing concrete boots. I like the sensitive pedal and lighter touch. It's the second thing I do when I get into the car each time.

Should be very noticeable for a stock M...roadster or coupe. The throttle response is very noticeable.

[gatorfast]

Like others have said, should be very noticeable. Sounds like something is wrong with your car's sport button.

Ill also join the train of say ing the sport button is worthless though. Makes the car very difficult to drive. Id rather just have it in normal mode and press the throttle according to how fast I want to accelerate instead of getting full throttle at the slightest touch.

Don't press it unless you're ready to go back in time. It engages the flux capacitor.

I like the sport button. I don't use it often but I am absolutely positively sure that when I do my gas mileage goes down! The car "feels" faster because you don't have to press the pedal as hard to make it go. My previous car had a very sensitive throttle so I actually prefer the sport mode - however I don't use it often as I find myself speeding far too frequently. That and I prefer the better gas mileage. But I like it and I find no issues driving with it turned on.

On a z4 3.0 I had, the sport button was ALWAYS on, because the car felt slow as balls without it

on the Mroadster, I use it for 5-6th gears on the highway, every single time. The car is too slow and unresponsive without sport mode, in 6th gear

Even with a supercharger?

[ZStig]

Every little bit helps

I'm not making much torque at 3000rpm in 6th gear anyway.

In fact, I wish I could program the sport button to come on automatically the car is in 5th and 6th gears.

Even with the ESS tune, which tames the sport mode quite a bit, I have used it once.

Every time I press mine a police cruiser shows up in my rearview mirror!

my 3.0si is in SPORT all of the time as well for this reason, and also the electric steering. There is MUCH less bump-steer when in SPORT vs. not. the car is a lot more responsive with it on. you ///m guys don't care about that though.
