Is it better to use paddles for roll racing..

But when I hit traffic, I want to be in Sport, Comfort, Comfort, DSC, D1. So one press of the M1 button and I'm all set. If I set M1 to manual, then I'd have to also push the knob right. It's just an extra step I like to skip.

How do you get the desired Drivelogic level in S mode if both M buttons are set to D?

Correct me if I'm wrong but all this time I was of the impression that D3 will put you in S3 when you shift manually.

My understanding is that when you toggle between D and S modes, it remembers the last Drivelogic level that was used in that mode. The only default being D1, at start-up or when an M-mode is turned off (where the settings all revert back to the start-up defaults of Efficient/Sport/Sport/DSC-on/D1). So, if the last time you used S mode it was level 3, then when you switch from D to S, yes, it will go to S3. But it is not systematically the case though. This seems to be true even after the engine was started, which would mean there is no default Drivelogic level for S mode.

As another tidbit, I personally dislike S3 with DSC/MDM activated. The powershifts are too aggressive for the tolerance of the DSC and MDM thresholds and cause a slight power cut on upshift. I prefer S2 with MDM. I however do love the crispness of the upshifts and the immediacy of the downshifts in S3 with DSC fully off . IMO, S3 can only be really appreciated with DSC fully off .

It's not really redundant. Using the shifter lets you switch between D and S without changing gears. Using the paddles means you have to change gears. I use this feature alot when merging in traffic to prevent the D mode from doing something unexpected.

What is the benefit compared to just shifting your self? This seems over complicated. A stock f80 isn’t exactly hard to drive or time shifts in.

Hi, Im having trouble for doing a 40 roll and 60 roll. Please correct me if I’m wrong. So I put the gear knob to the left for S rather than keeping it in drive, I hold the downshift which will throw me in the lowest gear for that speed so say 40roll, I’ll be put in second gear. Then u floor it? Will it upshift itself? This is the part I’m lost at. I’m hearing put it back into D. Thanks

Simple... put car in manual mode.
Drop to lowest gear possible for whatever speed
You’re rolling from. Floor it on 3rd
Honk, keep shifting at 6-6200
Rpm and hang on. Don’t rev past 6200 the power drops off and you’re slowing down.

1. Hold downshift paddle
2. Kick Down
- It will drop it to the lowest gear possible
3. Shift on you own
4. Pass the car

Nope.

Unless you're running an aftermarket engine tune, you should shift at ~7,300rpm. You want to always keep in the engine on boil in the 5,500-7,300rpm powerband

Holding the paddle without engaging the kickdown button on the throttle pedal will only downshift one gear.

Using the "auto downshift" feature will delay your acceleration, you're better off selecting the right gear before the launch from roll. While at part throttle rolling at constant speed, you need flick the paddle multiple times until you get the desired optimal gear for the speed you are at (40mph -> 2nd gear; 60mph -> 3rd gear).

This is what I have also, set your M1 and M2 to auto shift sport on one and sport + on the other. If you I in manuals mode, no matter what gear if you go full throttle and switch, the dct will drop to the lowest gear always.

For roll racing (and running a stage 1 tune, for instance) would it be less effective (and more risky) to shift at 7300 rpm than let's say 6500 rpm?

Would prefer to keep in D mode for a roll race (for optimal acceleration) though wondering if s3 or d3 would be better in this situation, with aftermarket tune..

Not possible for me to say without seeing a dyno plot of your engine.

DCT shift points in D are optimized for the stock tune, so they might not be optimal for your specific tune.

What I heard was putting it in sport + then moving the shifter to S , doing the kick down which puts your rpms high then do the 3 honks or whatever then floor it is the best way , I may be wrong though

If it's a 3 honk race or you are side by side. You always want to be in manual and lowest possible gear above 4000 rpm. Shift at 6200-6500 max. The car will do the rest.

[TopJimmy]

Papa's right. You shift at 6500 max, unless you're running out a gear to 7100 to finish a race without an additional shift. On stock motor, stock turbo, with any tune, power drops off from 6200 onward. If you go into the 7K Band things start to wear, and there's no benefit.

Maybe I'm misunderstanding how the thread came to this point, but just no dude. For max acceleration, you shift our lovely S55 at redline.

You can go for it. I've done dynos and street logging and get no benefit. I was shifting high before but F80Paul taught me to shift at 6200.

[deeldoo]

The truth of the matter is you red line first and second.

3rd = 7k

Rest at 6500.

To the poster saying redline every gear, it's only suggested if your race is going to end up in the 270kmh+ range where you would end up out of your powerband early.

For reasonable roll races shift at 7k 3rd, and 6500 the rest.

[HyeM3]

For what it's worth, my dragy times consistently show my 60-130's are .3 to .4 seconds slower shifting at redline as opposed to 6500 rpm

This thread makes a 6MT sound like a walk in the park

LOL. 43 posts in a thread about roll racing an automatic.
