With the Sport throttle, it increases both throttle sensitivity and slams the wastegate shut to make for much more meaningful in-gear acceleration. That's what I like the most about the Sport throttle when driving a 6MT. With an auto, you've got WAY deeper gearing and quick shifting transmission logic so running around in Comfort doesn't feel remotely as laggy and neutered. On the track, I would be in DSC Off because the Sport throttle could be a bit too much. However, when in Sport+, the stability control does do an excellent job of keeping the rear end pretty tame. The LSD in my car doesn't hurt ether.

I've seen this chart many times, and have studied it.
There are some similarities but also some differences. Maybe there's a change between generations of software, which wouldn't be uncommon from BMW or any other OE. As things progress software tends to change.. The post marks M135 from '10-'13. Then someone added M240i on top, with a note that the M2 has one similar (does that mean it differs slightly?). Who's to say the 2014-2016 m235i is the same-is my point. There may indeed be some slight differences between generations. That a side, it does show that in Sport+, traction or dsc is still active. (which is what I originally pointed to anyway) |

Do our cars apply differential braking as a matter of course in certain enthusiastic driving scenarios with certain driving modes?
I’m asking because I feel some odd behavior in tight turns during spirited driving at relatively low (sub 60mph) speeds. For example, the car may feel like it grabs on the inside and turns in more as it nears mid corner. I’d like to know what’s causing that sensation - differential brakes? Artificially (computer) Increased steering angle for amount of steering wheel deflection? German chassis black magic? And if it is artificial (computer driven) what modes turn it off? |

So will “DSC off” (long push of traction button) turn that off? For some reason I’d still like to know how the car naturally behaves -if that’s possible. |

Don't quote me on this but I think the mechanical LSD (if present) will interfere before the E-LSD does... when in DSC off mode. These cars don't really have an "Everything off mode".
And by E-LSD... I mean wheel speed sensors and brakes because these aren't M2s with real E-LSDs. |

Because the car gave me no indication whatsoever that what I was doing was risky enough that it needed to save me. To the contrary, it felt like “oh, you want to do that? Here, let me help you.” If it was just helping, I’m deeply conflicted about that. If it was saving me, I’d like some indication (feedback) from the car that I’m nearing a limit. |

2) That's called "torque"; as I suggested, our cars have a decided surfeit of it for daily driving. The only place I've found it particularly useful and handy is on a race track. 3) You'll need to learn your car's limits by driving it near those limits, and they're very high, I believe. DSC isn't anything dramatic, so perhaps you can practice moving the car around under you to the point that it kicks-in, releases, kicks back in again? That's why I suggested the Stonestown parking lot late at night when you've got a bunch of space to work with; alternatively, the roads going up Mt. Tam would be more fun, but I'd recommend doing that during daylight hours when traffic is light. I'm too busy looking at the road to spend time looking at the dash, but maybe it flashes a light or something shortly before DSC kicks-in, I don't know?

Definitely find some open lots or empty back/industrial roads (what ever works for your area) and let her rip with the aids on, then turn them off briefly and see the difference. |

Which, I also find weird myself. Which is why I tend to drive in Sport+ more. (the "twitchy" throttle feels more like it should, and makes the zf8spd feel more like a MT) Last edited by atek; 08-26-2022 at 04:28 PM.. |

Re: "There are just too many things and driving modes.", I couldn't agree more. That aspect of the car is overdone. I think the ability to turn DSC and DTC on/off have genuinely practical uses. Modes affecting throttle response, adaptive dampers, power steering effort, and engine mapping had to have come originally out of the marketing department. A set of all-purpose sports dampers is what the car should have come with; throttle/steering/engine mapping are best left to the aftermarket. That stuff, coming from BMW, is just frou-frou. I understand not everyone feels that way about these features; it's just my opinion. It's also why I knew before I bought the car that I'd soon afterwards have coilovers and a quality tune installed on it.
