yeah, even tuned to lower power levels, so if you wish to unlock it. but it seems some of the turbo cars suffer from temp control problems.
I have always been MORE than happy with the N/A power levels of my 03. I guess I just don't get the need for speed I can't use really or the issues associated with it. I guess my dick is big enough
(just keeding with you speed junkies)

Remember that a manual rev match doesn't begin until the gear is selected and clutch release has begun. So all they would need is to know what gear is selected and speed, both of which are already recorded in the data box. So the software would then match RPM of current speed and gear selected on clutch release, which should only take about 1/10 of a second.
The could even take a short cut and match RPM once the gear is selected and speed is known, but that would mean higher RPM's on in clutch coasting unless the car was in neutral.

remember, the Miata is a true sports car. sports cars aren't about massive power always. it's about the chassis and capability of the car. the Z with 289hp was more than enough car for many people it's just that the mega cars from like Audi and **** with 500hp totally skew people's perceptions these days. if the car is fun to drive and is not underpowered, it's still a sports car!
I just can't imagine how exactly a manual rev matching would 'work'. guessing it'll be a trigger once the lever slots into the lower gear, cause otherwise it'll be guessing when you clutch in. will it be quick enough for a fast shift? I don't know. seems clunky but what do I know. need videos
and though it is smaller I saw nothing about it being stiffer.

The truth is that the current power is "enough" for anyone, me included...but that doesn't stop us from wanting more does it? Most of us like to mod to varying extents..partly from the enjoyment of doing it but also because we like the little performance edge it gives. Does it mean you roll down the street screaming "I've got more than you?". Of course not.. but each of us feels it each time we squeeze the pedal.
332 won't keep me from buying the car. Why would it 306 didn't? If I truly wanted more power and that was the bottom line.. I wouldn't be driving a Z to begin with. Still.. I would have thought they would up the ante a bit more than they did when moving to the 3.7.

Anyone else think the rev-matching manual is going to save Nissan hundreds of thousands in replacement trannies? I'm sure they'll still be people capable of breaking it, but I'm also sure 99% of the premature synchro wear out there is from people not rev-matching.

Mostly likely it means than when you do a down shift (3-2) the engine will increase the idle speed to match the input shaft speed. This will increase the smoothness of the clutch release.
Think about when you come to a light and shift down to 2nd at 40+ mph. With out a rev match the car lurches forward and engine braking occurs. With rev matching the relase is smooth and no lurch.

This computerized rev-matching has some potential, but I'd expect the system to become confused during very spirited driving. Even if it doesn't rev-match until you select a gear, I'd expect uneven rev-matching if the clutch is released very fast.
And since the threads have been merged, I'll comment on HP too. Regardless of old or new HP ratings, the 370Z will be quite a bit faster than the e46 M3. As it stands now, the HR Zs are already as fast the as the e46 M3. The e92/e90 M3 is another story though as that car will be a good amount faster than the 370Z for years to come.

I really don't see how the rev-matching system will accommodate this and anticipate which gear you're going into.

If you think about it, many times rev-matching occurs at the same time you're actually shifting. So if I downshift from 5th to 3rd, I'd have the necessary revs even before I shifted into third.
I really don't see how the rev-matching system will accommodate this and anticipate which gear you're going into.

With modern beveled syncros, the between gear shiftings before clutch release really doesn't gain much at all. It saves a little wear on the syncro itself, but its minimal.
If someone is doing it for smoother shifts, then the rev blip is too early to improve smoothness on the chassis.

I hope this is not just a gimmick...Do we really need it NO but if its implemented in a reliable way, doesnt get confused during spirited driving and doesnt have penalities if its used 
then Im for it... Im partial to doing it myself...I do it so often now that I dont know what ill do with myself in between stoplights.

The e92 isn't so faster... it's still a fat goat that suffer of an incredible understeer, especially after few laps on a track.
It's sharp, for the first few laps.. it's really sharp.. and looks neutral to oversteering for its 420hp... but the balance is quite understeering at the limit when the front tires start overheating.
we will see... we will see.... a cayman S can catch an E92 M3 on a track and sometimes be even faster (slow technical track) if the 370z is going to match or overtake the actual cayman... that's it. is going to be faster than a E92 anywhere but straight line and really fast tracks.

This is like a nightmare coming true = manual rev matching.
If VDC, Traction Control, etc in many cars have buttons to turn them off, I just hope 370Z has a button to turn its rev matching off or like an option/package which I will be avoiding because I really enjoy the spiritual driving.

I hate comparing stock cars versus modded cars, but I have to since there is very little to mod the M3... the mods are much less attainable for it. The M3 is making high 12s in the quarter, and I think the Z will be commonly capable of that with exhaust/cats/tune/intake... simple bolt-ons that many people would consider. I'm not talking about cracking the engine for high compression pistons, or cams, etc. I'm talking about $2000 worth of simple add-ons that are highly attainable and easily installed.
A modded 360HP Z has a very similar power-to-weight ratio as an M3. And the 400+ pound lighter Z will pay dividends on a track.
3200 pound Z with 360HP = 8.89 lbs/hp
3700 pound M3 with 414HP = 8.94 lbs/hp
8.89 > 8.94
Once again, it's all about the weight savings.
