M Sport Button

[mmm-five]

Yeah hold a constant throttle on and press it... might get a bit of acceleration as it magnifies the input from the throttle to be less proportional.

I never get that, and have to release the throttle slightly and reapply to get any effect.

However when I switch off the sport mode the engine revs drop instantly and the car slows slightly.

Same here.

Never bothered with it on the E46 M3, don't bother with it on the Z4MC either.

I thought the throttle response on the M3 was lethargic without the sport button on and I automatically pressed it when I started the car. Conversely with the Z4M I find it a waste of time and never use it.

Automatic accelaretion of the vehicle possible??? WTF :?

Mine does this too. I always lift off the throttle before putting it into sport.

I haven't tried it in the M but it happened like that in my old M54 3.0 Z4

when i press my sports button my penis enlarges, is this normal?

 

[ChawenHalo]

So definitely no effect on ESP? :? If that the case then I tell, this car is playful on hot tyres! NO light flashing whilst getting tyre skeeling

I hate the sport mode, even on track use. The throttle pedal is too sensitive, and it does not make the car going faster at all for me (even slower regarding lap times). For me it's useless, or at least a kind of placebo.
I don't know if it has any effect on ESP, anyway I always disconnect it when driving "fast".

That's how I find it with the 3.0 Si. I'm not sure if the revs actually drop when taking it out of Sport Mode, but it certainly feels 'heavy' all of a sudden. Can't say I notice any difference to either the steering or the clutch.

I am slightly surprised about the wording in the manual, because the system only becomes active when the gas pedal is pressed and the button is pressed, after releasing the gas pedal again.

When on the pedal, pushing the button again to turn Sport off, the system immediately deactivates.

On a Z4M it is purely a difference in pedal press to throttle ratio that changes, which means you need less pedal movement for acceleration, and makes the car feel nervous because any change in pedal angle will have a stronger effect.

So yeah, placebo effect

agreed .. completely useless on the z4m

The standard mode is already too aggressive in my opinion.

It's snake oil as others said, the map is identical, it doesn't even make it more drivable. It just adjusts input sensitivity, it can make heal and toe easier though. But I've learnt to be a bit more direct on the standard position, which required a bit more focus initially

I wish we had an M engineer on this forum.

Why? To ask why the button doesn't do more? It changes the input required on the throttle for the throttle position at the engine end.

In normal mode you press the peddle down 20% you get 20% throttle, all the way up to 100% pressed gives you 100%.

With Sport button on you press the peddle 20% you get 30% throttle, 40% gives you 70%, 50% gives you 100%. - all numbers are for illustration etc, this isn't actual figures etc.

It does not change steering (we don't have elec steering on M), it doesn't change dampers (we have normal simple oil filled dampers), it doesn't change ESP (you can always get some slip with TC on), it doesn't change gear change speed (we have a stick) - it's only there because the marketing boys asked for it!

I have never seen anything (from an official source) that says otherwise.

Turn key, start engine, roof down, dsc off, sport on.

clutch in, first gear, drive.

On my M3 all it did is change the throttle response to a linear response from a learned curve response, ( The car jumps if you are on the gas when you press the button) and it increases the fun factor by 2x. :wink:

I use it everyday! BMW's throttle response is horrific!!!!!

Absolutely! Out of sport mode, the throttle does almost nothing for the initial part of its travel.

agreed .. completely useless on the z4m

Really??

We should not talk about the same Z4M model :lol:.

In my E46 M3, I found the M switch much too sensitive for daily use, although it was pefect on the track.

it was great when letting friends drive it! They were invarably like, Man! this thing has soo much power!!

perhaps his throttle sensor got out of tune. lol
