Help me learn how to accelerate hard with the dct

[Silverlining_m2]

Ok first y'all I apologize. This is my first ever dct car. I'm adept at driving a manual, and obviously an automatic is well, automatic.

My previous bmw was a stage 2 tuned 435i rwd with a zf transmission. With all sport modes on I had to feather the throttle a little, but was capable of running 0-60 in the 4.2's

I know 0-60 doesn't mean shit. I know the f82 isn't a drag car. But I did read it runs a 4 sec 0-60. I also read it accelerates faster in all auto mode, with d3, and s3. Whenever I do that, the car bogs down when shifting from 1st to 2nd. I believe the traction alert flashes and the car pulls power, shifts slowly (kind of rocks your head forward) and starts accelerating hard again. Mind you I made it there in 4.37sec anyway.

Aside from just NOT just turning all the traction nannies off and driving in sequential mode, what am I doing wrong? I'm pretty certain I have purchased a good running and well maintained car. It would be one thing of I was missing the shift points manually, but it seems the dct itself is missing them under WOT? Or are the nannies ruining all my fun?


Yes I did search the forums for this specially but didn't find anyone else asking this. New car. Just making sure I'm not missing something.

You need to take everything off, set it all to sports+ and do launch control. Make sure you warm the car up first and you have really sticky tires! Only way to get proper 0-60!

[Cajun1]

In a safe environment, which cannot be stressed enough, nannies off and be very careful! These cars have power.

I'm positive my Burger tuned 2015 335XI will crush my pure turbo stage 2 15 M4 outta the hole. The power vs traction variance of the M4 is outta control!

Try MDM, switch to auto and set your drivelogic to setting 2 instead of setting 3 and see how that goes. Still gives you a little bit of nanny. I've found drivelogic at setting 3 upsets the tires too much.

Thanks for the replies. Ok so clearly it's "nannies off" for the win. I'm astonished how much it wants to disrupt my acceleration over just about any tire slip at all. It is for real bogging the car down when it chirps the tires into 2nd. I already had her sideways earlier with the traction control off so I'm aware of just how free she can be in the rear. How fun though! A driver's car!!

Like others said, all nannies off or at least try MDM mode. Standard TCS setting is wayyy too intrusive, I've had the car pull power at 100mph but that was on winter tires...in Mexico of course. Can't help you on DCT settings as I've never owned a DCT car.

[bsmf8x]

The bogging down is 100% traction control and has nothing to do with the Dct if you're in s3/d3

You can try shifting even at 7k and you'd probably get similar acceleration also it keeps the car in the power band I know a lot of people who race shift at 6.6k but not sure if that's bc of their tune

[HyeM3]

Factory rated 0-60 times are usually conducted in perfect conditions, often times on a prepped surface, and with a 1 foot roll out. So that 4.2 you got is pretty solid on the street. With a 1 foot roll out you're probably at the 4 sec factory rating. As others have said it's best to turn the nannies off, the traction control on these cars is very intrusive unless you code in the euro or gts mdm. It's definitely what's causing the car to bog

Doubtful.

The traction control is much improved in the newer software revisions. After getting my 2015 updated I found the intervention is much less harsh without much of that bogging down effect and it allows a little slip even with it fully on. Makes accelerating fast from a standstill easier.
A dealer can do it. Or you can go aftermarket with THOR and flash the CS software.

Run street tires on both side by side on a regular street. A video of a drag car with drag wheels trying to set a record doesn't mean a thing. I own both of them and I know the results. If you doubt it, than give it a try if you own the same 2 vehicles and let me know the outcome

[deeldoo]

F8X would get gapped by a prius from a dig to about 60.

People don't understand that first gear is for burnouts, second gear is for power-sliding/drift, 3rd gear is for racing.

Don't bother launching this thing, unless you want to end up in someone's living room

Stock turbos fall out of boost past 6.6K so for roll racing and best times you shift before redline

Hahaha truuuuue.

Also drive 6mi/10km before you use the launch control.

It's stated in the manual as warmup for the car.

Bone stock F80 running 11s. Doesn't seem like there is any traction issue here either. Might need a driver mod

I thought mpss WERE good tires lol. And mine are brand new. I will say its only 50° here though. I will look into the update.

A prius runs a 4 sec 0-60? lol

9.6

MPSS are good tires, the 4s are better
