I am the first to criticize BMW marketing. They do a lot of good work but often on purely technical points they just get it wrong or really stretch things. I don't recall preaching to you from BMWs press release on M-DCT about how the surge was created. I have other arguments and sources for that. I have indeed quoted that document selectively. Obviously I don't believe the quote therein of shift times in "milliseconds". It is just not possible. I may have used those times in simulations just to explore simulations but it reality it is not possible. However, when they say things like "lifetime fluid" or designed for hard track use, those things are either True/False or very darn clear cut. Read, interpret, filter with some logic and experience and decide for yourself. What you have in quotes above ("without the slightest loss...") is clearly marketing. PURE marketing. Think for yourself! The spark gets cut, the acceleration stops during that time, period. Logic and physics dictate a loss in momentum, however small. I am always trying to speak precisely and encourage others to do so as well. |

swamp,
I was only messing with you mate. You know when I discuss things they are at times very tongue in cheek and this was one of those occasions. |

Anyway, how do you plan to calibrate the accelerometer? More importantly, if we were to put together a setup, would you have access to other DC cars such as an Audi and a GTR? A Ferrari would be nice, too!

Access to other cars is indeed a problem on my end. Not enough buddies with nice rides. Have not considered the calibratioin of the accels fully. Many do come calibrated though with a mv/V/g spec or similar. An ideal test from my perspective would be: M3, GT-R, GTI, 430 Scud, Mitsubishi Evo, the Jag XK-R automatic and a top notch short throw MT vehicle. |

Another approach might be to simply post in other car forums and invite people with different rides to do a test. I bet folks would be up for it. And, I'll volunteer the "top notch" MT vehicle. Anyway, we don't have the equipment yet, so we'll see...

As far as a "top notch" MT vehicle, I think the M3 (and every other BMW) is out. Don't get me wrong, I have a 6MT on order and my E46 also had the 6MT, and I really like their feel, but even with an SSK, it isn't anywhere near as good or as fast as the MT in an S2000, for example. The throws are just too long and not nearly as crisp. |

Since this test has virtually no overhead once the equipment and the cars are available (the differential is not going to "fall off" or anything as some would like us to believe on that other thread), I suggest we do it both with MT M3 and S2000.
