Mystery "Possibley" Solved - Major 0-60 Time Variations

my2004Z · 01-09-2010, 07:39 PM

Maybe someone else has covered this I'm too lazy to search for more than 10 minutes. I am convinced that the reason for such large variations in 0-60 and 1/4 mile times for magazines, car shows, and racers/drivers is the adaptive shift control on the 370Z, particularly the 7-speed automatic transmission. This might even be the reason for some of the "grinding" noises folks hear when stopping and the 7AT downshifts from 3-2-1.

Per WorldCarFans.com:
"The Adaptive Shift Control (ASC) is supposed to quicken the time between shifts to about 0.5 seconds, which may sound fine but it's something you most likely need to test on the road to see how well it really works."

My understanding is that the ASC monitors your driving habits for several minutes and starts adapting based on the drivers inputs. Is it possible that some of the tests are run with a few Sunday driver warm ups and not after flogging the car for 15 minutes or so? I notice a huge difference in the "kick" between shifts if I've been pushing my 370Z 7AT hard for a few minutes vs. driving like an old lady most of my 20 minute commute from work.

I'm just saying.... maybe this should be accounted for in the tests.
Anyone know of any tests isolating and measuring the ASC? Is this even something that can be tested?
