It's the bomb!!! Turn it on, and just step on the brake, apply the clutch and the revs are matched for the down shift. So cool for a manual transmission@!@!

 

Nice, but we don't need another thread on this. [blue *****]

Strange, I searched for syncrorev match but never got any hits.

Either way, it's cool. Maybe even enough to get me to trade in. And thanks for the link.

EDIT: If I could spell synchro then this tread would not have been started. Oh well

 

I'm glad it can be turned off! Making a perfectly rev-matched downshift is very rewarding.

 

No problem

Maybe they've improved the transmission in such a way gear shifts are super silky smooth. I'm sure SynchroRev won't work with current Zs with notchy clunky gearboxes since getting in gear quickly is hampered by something getting in the way.

 

It probably has a gear and clutch position sensor, so it can tell when the car gets in gear and when you`re releasing the clutch. In theory, it could work with the crappiest of trannies.

 

I couldn't disagree more with the 'notchy clunky gearboxes" comment on 350Zs. Both my street and race 350Zs have beautiful actions in the riflebolt-like shifter. If you know how to heel-and-toe downshift, the shifts are light, easy and direct. As for "getting in gear quickly is hampered by something getting in the way", what you're referring to is the syncromesh mechanism that matches the speed of the input shaft with engine RPM. That was a great advance at one point and anyone who has driven a dogring racing or non-synco gearbox can attest.

The point is, while Nissan developed another technological wonder in SyncroRev, don't discount how GOOD gearboxes have become, especially with the 009 version 350Z 'box!

 

Interesting. I have a CD -008 transmission that was replaced in Jan '06. It was great the first few months, and then it started getting more and more clunky. With the cold weather settling in, getting in gear is getting difficult. It seems like downshifting is smooth, but upshifting is a pain.

[crossing fingers] the latest transmission won't have this problem... it kills the fun when my wrist aches from rough gear engagement.

 

Again- don't just cross those fingers! Learn how to heel-and-toe and it will ease those downshifts by a thousand times. And for smoother upshifts, try holding the gearshift **** lightly with two fingers and your thumb. Wait just an instant between shifts and make smooth, deliberate movements to engage each gear on the upshift.

 

I have a confession.....i do NOT know how to drive stick yet haha. What a car the 370Z would be to learn it on haha

 

The OP said it only works when your foots is on the brake? Does it only work if your foot is on the brake?

At least it can be disabled.

 

Let say you're driving in 4th gear ------> coming close to a bend/turn --------> use brake to slow down the car a little -----------> clutch in -------> shift to 3rd (this is when car will rev match) --------Clutch out -------> resume foot on the gas padel.

Watch this video and it'll give you an even more accurate idea

It's lame.

If anyone owns a manual transmission and can't even do something as fun (and necessary) as rev-matching, then they shouldn't even be driving an MT to begin.

I'm glad there's an off button. I like doing my rev-matching myself

 

I understood how it works, my question was whether it only worked when brakes are applied. I rev-match downshift (actually I double clutch, but same premise), and I often do it without touching the brake. In your example (not race driving, just spirited driving), I would double clutch before a turn to slow down and not use the brakes at all. In fact, I hardly ever use the brakes even driving around town. I rev-match every downshift including when I need to get a downshift in from 6th to 2nd or 3rd. With rev-matching I can get into gear smoothly and goose it like butter. Without rev-matching it's much rougher and harder on the car. Obviously if you need to pass some douchebag in a diesel pickup truck you wouldn't want to hit the brakes to get the rev-match to happen.

All that said, I hope it's a feature that remains "OFF" even after your shut the car off. Unlike VDC which always turns itself back on. I'd just assume not have this feature. It might be cool if it didn't require the brake as I could become lazy in my style of driving and not double clutch, but to only work when using the brake would throw me off especially the occasions I heel-toe (brake and rev-match simultaneously). What happens when someone like me who does this like breathing and doesn't always think about it tries to heel-toe with this feature on?

I really hope they make it a feature that stays off when you shut off the car, I'd hate to have to remember to turn it off each time.

 

I'll give it a shot, thanks! As for heal-toe, I don't track so I've grown accustomed to blipping the throttle to downshift before applying brakes.

 

I just read the brief description on the NissanUSA site that has the 20 slides or so. The slide for this feature doesn't mention the brake. It does mention that it monitors speed as well so I'm thinking for 6th to 5 downshifts and relatively mild downshifts at low engine speeds, it may not even operate.

Didn't seem like they were using the brake...

 

Seemed like it wasn't really doing it.??

 

No we did not.... No brake, does not matter what speed you are going, or what gear you are in - works right up to redline. You can even skip gears and get a dead on match.

This was a very quick test drive, we only had an hour, and we were on a public road so we could not get on it hard. We will do more testing next week when we have the car for a few days.
