Point= 1:1 = invalid sometimes...(i.e. when not practical refer to paragraph #2 in linked post)
4AT BTW
I dyno in 2nd which is not 1:1 since it's less strain on the engine, gives a smoother curve and does not deviate much from 3rd.(less than 1whp).which in fact is 1.000:1 on any 4AT A32/33 Maxima.

What the heck is all the fuss about discrete ratios in the CVT? For a launch or on the dyno, fine, but are they really useful otherwise?
I was always under the impression that they were really only there for the tardcakes who think that the ability to let you pick your own gears makes your car "sporty"...

That's the main reason they are there. But hopefully it helps on the dyno.

my car will see 99.999% dury in DRIVE.. 
if i want to row through gears i will take my supra out. This is purely to find out what kinda power they make, and if i decide to dyno mine, what gear to do it in. on the supra. 5th is 1:1,, but maney people dont want to run up to 160mph on the dyno so we dyno in 4th.

It's a Constant Velocity Tranny. It is basically infinitively variable gears. It uses this weird twin cone setup. They've been out for a long time now, just that no one uses them because of durabilty issues.

CVT = Continuously Variable Transmission.
And it's power handling ability that's hoding them back, not durability.

Doodfood has got it. I think audi had it on their FWD A4 a while ago.

Well I think its definitely an upgrade from 5AT's thats for sure, but I'll stick to my manual, I like to be in control and I'm not feelin the 3 tranny coolers..
Cedric/ Gloria? I assume..

ok i went to new model training on the 07 maxima and the reason we went with cvt in the maxima is 2 reasons 1 better fuel economy, thats the most important and 2 in xtronic mode it feels like a manual not a normal tiptronic
i guess thats why it's called an xtronic cvt transmission,
by the way it's very reliable,.

1. Over the years, Nissan gradually moved the Maxima up-market until it eventually became something that virtually no one wanted with a stick.
2. Manual Maximas never sold for shyte in the US, even when the Maxima was more sporty.
3. The CVT is good enough that many manual drivers can be sold on it.

I can agree on the first two.. but on that last remark I think you should reconsider what you said, if not, then be slapped.

Why? I didn't say it's the right choice, or that most manual drivers could be sold on a CVT. Believe me... I am the LAST person to endorse ditching a manual for anything on any car that's remotely performance-oriented. I'm just saying that there are a lot of people who mostly drive stick because they think it's faster, more durable, and more efficient, and that mentality is fairly vulnerable to a pro-CVT argument.
If it makes you feel better to think I meant "weak-minded FOOLS could possibly be convinced to take a CVT over a manual", then that's what I meant.

much much better, A+ revising. yeah I can agree, then again on those mornings where your half asleep and dont feel like shifting or late nights when youre half asleep CVT would be nice.. then again the manual probably has kept me alive by keeping me awake. And, if by some stretch you do pass out the clutch releases and hopefully you stall somewhere where you wont cause too too much harm.
So manual FTW, but everyone with a brain knows that.
