Optimal Acceleration w/o Launch Control
So - after having this car for almost a year and 16k miles - the rush I get from this car's brutal acceleration still has not gotten old (love that flat and precise cornering too)!
Anyway, I've been trying to find "ideal" settings to use for optimal acceleration, depending upon whether or not I want to minimize wheelspin. Here are my thoughts thus far: 1) Maximum Rate of Acceleration with Minimal Wheelspin: A great combination of settings that I like for max acceleration in 1st/2nd gear while simultaneously minimizing wheel spin (whether or not during shifts) is: Throttle: Sport EDC: Comfort Drivelogic: S1. 2) "Fun" Acceleration - Still very Quick/Some Wheelspin: My favorite "fun" acceleration combination (where I don't care quite as much about wheelspin) is: Throttle: Sport+ (to get best sound from exhaust) EDC: Comfort Drivelogic: S2 (With S3 max throttle, the shifts are so firm that the DSC in full or MDM mode will cut power during the first couple of shifts - S2 gives you the chirp of the tires with only a small amount of wheelspin and very little if any cutting of power while in full traction control or MDM mode). Thoughts? |

Still trying to figure this out. If you mash the pedal, the car revs until about 3300, then dumps the clutch, and the tires light up. Try to stall up the Rams by pressing the pedal and brake together, and the clutch engages immediately and bogs the engine. Still working on mashing pedal then pulling off 1/4 to limit slip after clutch engages at 3400. LC at 2600 on a clean street/track still the best method.

I'd say DSC off, Engine in Sport+ and DCT in S3. I lightly dab the throttle to get the clutch to engage and then mash the throttle to blast off.
That kick in the butt with every upshift just rocks There is only one way to fully appreciate the fury of the S55, and that is with DSC off. Be ready to catch it though .

When I had DSC ON, S+/S3 and tried to mash the throttle, DSC intervened often :, can you please explain "light dab"? Thanks |

So yes, to truly appreciate the fury of the S55, you need to have it all off. You need to be conscious of the additional risk though and be ready to catch the rear if it steps out (and likely will). What I mean by light dab, is a slight push on the accelerator to engage "creep" mode. Same as when you are in traffic or parking and want the car to move forward slightly. This gets DCT to start engaging the clutch. You can then aggresivlely roll on the throttle without getting a clutch dump and resulting burnout. I also found that Euro MDM is so much better than the North-American-MDM. With the NA-MDM, it would cut power on every upshift. With Euro-MDM you get much smoother acceleration.

- Pic 1 shows the lights for MDM and "DSC off", in this mode MDM still intervenes, so for a novice driver it's better to keep this for some fun and some security. -Pic 2 shows and additional text at bottom right of cluster where all safety electronics are disabled, a mode for instructors and experts such as yourself Now that I get all this, even w MDM I found myself like riding a bull in a rodeo I need me some class time and practice at an M school. My wife said why is the car so unstable I said, honey, I need to learn how to ride this beast. |
