QuoteNearly every piece and component of the 370Z has been rethought and redesigned, including a shorter wheelbase, greater use of lightweight body materials, larger engine with 26 more hp, a new 7-speed automatic transmission and the world?s first synchronized downshift rev matching system for the 6-speed manual transmission...

The manual matches revs for you?  Hope you can turn that off.  It'll drive those of us who actually match revs on our own nuts.

I would find that extremely annoying.

Exactly how does it know which gear you're going to downshift into, or whether or not you're going to downshift at all?

Interesting concept, but completely useless.
Maybe we need to start off small. I mean, they don't let you fuck the glumpers at Glumpees without a level 4 FuckPass, do they?

Back when I was working for a trucking fleet, I seem to recall hearing that one of our rigs had a gearbox that would match revs for you.  Maybe I'm mistaken and it was just synchromeshed.

Never heard of that, but there's lots i haven't heard of.

Still, I wonder: how would the computer know what I want to do? I mean, sometimes it could predict it perhaps: but it can't see a corner ahead or read my mind.

Imagine the horror of being so sentient and intelligent you can predict the future and read minds, but the only decisions you can ever make are things like "3rd gear or 5th, coast, or blip the throttle?"

Maybe you put it in gear, let it rev match, and then let the clutch out.

Assuming the throttle is DBW, a setup like that would be a cheap way to extend the life of the synchros, since it would only require software changes.

If the transmission had a sensor pack either in the shifter detent it could tell the PCM which gear is being selected and match accordingly, but that would require that you declutch, stick the shift lever into the appropriate detent, and then wait for the PCM to rev match it for you before releasing the clutch again.  Sounds tedious when I can do it without too much thought on my own already.

I couldn't even imagine downshifting without rev matching.  I tried to explain it to my friend once by showing him what happens, and the first three times I tried it, I rev matched.

It already has the side profile, I'd imagine that the original front would only be an improvement. :huh:

It's pretty simple IMO

When ur cruising it's no biggie.

When ur accelerating u have ur foot to the floor so rev matching is obviously not needed.

When u are playing Keichii Tsuchiya on your favorite mountain pass, odds are u will need to rev match during braking... ECU senses heavy braking, u press the clutch pedal in. Starter switch on the clutch sends signal to ECU, ECU says "hard braking + clutch in = rev match to previous gear". U aren't gonna downshift two gears in one gear change to get into a corner, at least unless you like changing motors.

Only other time u "need" to rev match is if ur on the highway gearing up to pass someone or just floor it. ECU can say, 'ok cruising in top gear at 60mph... clutch in, coasting, prob. looking to pass. Rev match for a 3rd gear downshift'. Cause really, 330HP in a car this size is enough to accelerate from any speed in any gear respectfully on the highway, so I can't imagine downshifting in this unless I wanna floor it/hear the engine scream.

Seems simple to me. I bet it will be implemented smoothly, Nissan wouldn't roll it out if it wasn't. And more importantly, for u Schumachers, it probably has an off button.

Like someone said it's most likely in the interest of gearbox life.

Why the hell did you just go an entire post using "u" instead of "you"???

Secondly, do you really think that I'd never need to downshift two gears to enter a corner? What if you're going from a straight away into a tight corner? Sure, you could do two quick downshifts, but sometimes I'm lazy and don't feel like doing that.

I go 4-2 or 5-2 for corners all the time.

Where are all these blown up gearboxes they're trying to save us from anyways?

I'm sorry, but there's no way for the computer to know when you're going to stop braking and which gear you're going to be choosing. It could be as drastic as a 5 to 2 downshift

I'm guessing since NYC streets are mainly like +++++ I have never had the chance to do a 5-2 downshift. Again they could turn it off. Thinking about it more though it just seems like a stupid gimmick, but it wouldn't be that hard to implement.

All this could be done using an advanced shifter gate that has the ability to sense what gear the stick is about to be moved into. In alot of stick you can feel almost two resistance points as you slip it into a given gear. Now imagine if there was a sensor pack that could sense this "initial" movement and then rev match by the time the stick is fully moved into the gear position. This would mean it would be able to match any compination because it isn't thinking which gear you came from, just where you are going. All the computer needs to see is that the shifter is starting to be moved into 3rd and then match the revs for the speed in that gear. Complicated, yes. Pointless, to me. Novelty, certainly. If executed well it could be a "good" feature meaning it wouldn't completely piss you off(GM skip shift anyone?). I think it is completely possible and even possible to integrate it well enough as to make it seem "natural". I personally would care for it though.
