I wish I could program it to be like that all the time, really not a fan of sport throttle.
Got it, so no need to change drive mode, I can directly hold DSC off without being in Sport or Sport+.
Good to know!

Yes, but keep in mind, without an LSD you will shred your inside tire if you really push the car. With DSC off. Im on Ohlins coilovers and before the LSD I would smoke the inside tire on long sweeping turns.

DSC fully off will disable the rear braking in corners? (fake torque vectoring).

In full off the eLSD activates so even then your rear brakes are being used.

Only way to stop it is to code off eLSD.

Im not sure tbh, Im just saying what happens. I wasnt able to do it at first, but as I learned the car better I couldn't drive it at the limit without ruining tires.

eLSD (where ABS is used to mitigate tires rotating at different speeds) only comes on in DSC-off mode. I have a mechanical LSD and have eLSD coded out, as I've never been impressed with how it works, and found it to be more of a nuisance than anything else.

In Sport+ the stability control parameters are significantly reduced; with a mechanical LSD, I almost never feel it intervene, even on track.

Which LSD do you have? Are you able to feel a marked difference/improvement even with all the "nannies" on like in Comfort, Sport modes?

DSG off as in fully off, or SPORT+ also counts?

My 2 cents. I've experimented with both Sport+ and DSC off. In Sport+, I feel traction control kicking in and hurting my drive off some corners, which is why I tried DSC off. With DSC off, my rear tires were just spinning more off the corners, so that didn't improve my drive either. My lap times between the two were about the same, so now I just keep it in Sport+ mode for that added bit of spin protection. Maybe that will change the more track driving I do though.

I found that as I gain more and more experience, my lap times improved with DSC completely off. DSC will act as a "coach" so long as you are paying attention to that yellow light. If you see that light flash as you come out of a turn and add throttle, then you know you are either applying too soon or too much. However, it's easy to rely too much on DSC to save you and instill bad habits if you are blinking constantly. Try turning it off, since you are getting the same times, then you won't lose anything. You will learn more about your car and you will get faster and faster knowing how to modulate the throttle and manage your rear traction. Added bonus: even if you lose a bit of traction, you can be on the throttle a bit sooner since DSC won't be too aggressive: sometimes you want a small amount of slip. This is one thing the non-M F30's need: M Dynamic Mode to allow for more slip while still being there for extreme circumstances where you have violated the laws of physics.

eLSD only comes on with DSC fully off; Sport+ has reduced thresholds, but no eLSD.

For a while now I've been saying that Sport+ is awesome, as it never seems to intervene even when driving at (or slightly past) the limit.

Well, I learned something recently when working with a tuner... long story short, back in 2016 when I had my eLSD coded out, the coder apparently coded out all stability control in Sport+. So all this time running in Sport+, I had no stability control at all active... which of course explains why I never felt it intervene : )

Oh, and along with killing Sport+ DSC, they also disabled ABS. Which makes sense thinking back to the occasional brief lock up on track over the years. (Nothing dramatic, as I was always able to manage it... but I always wondered how I occasionally overcame ABS when threshold braking!)

So I guess I have no idea how invasive Sport+ DSC might be...all this time I thought it was great because it seemed to be sophisticated enough to let me drive at the limit and leave me alone when I didn't need it!

That's kinda funny but also interesting. Are you going to fix the ABS or do you just like having your car act like a proper, old school race car? 😁 i've been running DAC off since my first track day. Definitely the way to go. Couple times I didn't hold the DAC off button long enough and I could tell the car didn't feel right. Shut it off and I had control back. If you drove anywhere near the limits of adhesion, it will cut into II ur fun. I've been wondering lately how I can have Dynamic Stability Control off and have everything else set to Sport+ on the track. Any idea how hard it is to code out, or even how to go about coding out DSC in Sport+?

I recently installed an MPerf LSD. If I full disable DSC, will I be full mechanical LSD or will I have the eLSD intervening? If so, running in Sport + would mean no eLSD but nanny intervention considerably well past the limit, right?

With a mechanical lsd you'll never get enough slip back there for "eLSD" to trigger. It's really just the car applying ABS to one side to mimic a mechanical lsd.

Max slip with the Mp LSD is ~30%, so eLSD would trigger somewhere above that as no coding is needed to go to the Mp LSD.

As for tire pressures I have RE-71R square setup and 36 PSI hot seemed to be the best for me so far.
I ran with Sport+ on at Road Atlanta this weekend, first time at the track and didn't know it so well. I think I will continue to leave it on in the future as I have worked on my throttle control with the sport+ mapping. The technology is much improved over older version in BMW. I didn't realize it until I got an E90 335d. The F30 version of sport+ is LIGHT years better. I will probably continue to leave it on for the safety margin. I did feel it kick in once downhill between 11-12, and it's so subtle you hardly notice it, just a lack of acceleration really, but it doesn't lower/cut the power, it's like auto maintenance throttle. Wouldn't let me add any more at a certain point.
