If you're concerned about auto rev-match, it can be coded off in all modes; again, not something you should worry about until the car comes. Living in NorCal, unless you decide to take the car on a ski trip in Tahoe and have to drive in snow, Eco mode will be useless anyway.

From the interview with Juergen Poggel:

Quote:
In the SPORT and SPORT PLUS modes, the waste gates remain closed under partial load and the mass flow is routed through the turbines, to ensure that the turbo chargers are already rotating at a higher base speed even in standby. Moreover, certain special engine control functions are brought into play that accelerate activation of the turbo chargers. This means that the car responds more closely to the accelerator in SPORT and SPORT PLUS modes.
Would be nice if someone could explain that to me like I'm 5.

Alls I knows is I can hear the turbos better in Sport+ so it's gooder.

I have a '15 that I own outright and I'm not worried about some cooling fan wear. I'm not even worried about the crank hub.

The GTS DCT flash solves the jerkiness problem. 😉

Not my ‘18.

I’m in sport mostly and efficient the rest of the way.

Wouldn’t be concerned. Just be careful. Respect the power.

Sport+ for me all of the time as well - with DSC off (oops, did I say that ). The "bucking bronco" issue is definitely more likely to happen with a 6MT in Sport+ vs Sport/Efficient (happens to me occasionally). But proper foot control can prevent it.

I wish there was a way for there to be separate controls for Sport+ throttle and the rest of the Sport+ engine setting. Because that damn throttle is the worst. Yeah, we can learn to control it, but why do we have to? There's other benefits to driving in S+ on the street, but they're somewhat ruined by that touchy throttle

I know it's not exactly the same thing but my old E90 had a "power" button whose sole purpose was to make the car buck like a bronco when you weren't careful. I mean the fucking thing didn't actually add more power or anything. But the great thing about that button is that I could keep it off forever. I'd gouge it out of the console if I weren't worried about resale.

This is what keeps me from using sports+ all of the time. I plan to drive my car for many more years and most of the time I'm in moderate to heavy traffic where I cant take advantage of the throttle. I cant be bothered to tweak it either every time I want to pass someone or take off at a light, so I make due with regular sport mode. I wish the throttle mapping could be adjusted independantly of the other sports+ features.

Aren't the waste gates closed anyway until they reach the max preset boost pressure regardless of throttle mode?
ISTM that once you are "on boost" the full throttle acceleration rate is the same regardless of throttle setting.
Is there an overboost facility?
I'd love to read a proper explanation of the cars boost control.

My rule of thumb is Sport+ once warmed up and until I encounter stop/go traffic. At that point it's more work than fun.

Have any of you seen any disadvantages in keeping your M4 in Sport+ all the time (even in rain), i.e. harsh ride, lack of traction, etc?

Thanks
don't ever put it in sports+

you'll lose control of the car

you can't handle the power

the car will break

it farts too much

Efficient is only for keeping the neighbors from hating me in the morning. Otherwise Sport+ all the time...only because of 6MT and like to rev match for myself. I never had problem with throttle response in the '15 or the '18. Butt dyno feels the same to me between the 2 cars in sport+, but the diff in the '18 is much more tame.

Of course could get a custom engine program that would shut off rev matching in efficient and/or sport. But won't do that under warranty.

I find that in normal (slower) driving, revs drop too much on upshifts with sport +. Am I missing something? I often want to be able to shift casually, not in human DCT mode, and that causes rev drop in both efficient and sport +. Sport seems to work best. Perhaps just a personal preference thing ?

Sport+ most of the time and Sport only in bumper to bumper

I sometimes need to go with sport in bumper to bumper because the car can just jump so fast and some other cars don’t accelerate that instantaneously.Basically I use sport to not bully some of the non performance cars.It doesn’t really become necessary when you are behind something else high performance .
For some odd reason it’s never ever been a problem when I am behind another M Car. I CANT FOR THE LIFE OF ME FIGURE OUT WHY ?

I find the rev drops to be too slow on Sport. I occasionally let the clutch too fast on 1-2 shift in Sport and the car jerks.
