Synchro rev questions
 

Hi guys,

I am looking at a 6MT car with the synchro rev. I had a few questions about it if someone who has it will fill me in :)

1) Does it rev-match on upshifts as well as downshifts? How does it know if you're going up or down? Like if you are cruising at 40mph and want to downshift to get more acceleration, or let's say you acceelerate to 40mph briskly, then let off the gas and cruise, then want to shift up a gear to drop the revs... how does it know what gear you will be going into?

2) Does it ever get it wrong? Like you are coming to a light so you push the clutch in, and it thinks you are going to upshift when you were actually going to downshift.

3) Is there any way to "cancel" it (without pushing the button)? I don't always shift linearly... I may pull out from a sidestreet, get on the gas hard in 1st and 2nd, but then want to just shift into 4th to cruise. If it's holding RPM's at (for example) 4000rpm waiting for me to shift into 3rd, how do I cancel that? If you release the clutch while the shifter is in neutral, does it cancel it? Or if you blip the gas, will it cancel the auto-rev? Is there any way to cancel it other than pushing the button (which obviously you wouldn't do every time you wanted to shift non-linearly)

yes

no

its fine, dont worry much. it works fine

It looks and sounds like it rev matches on upshift, but it doesn't say anywhere whether it does or not . I think there is a sensor at each gate that lets it know when and how much to rev depending on current transmission speed.

upshift or downshift the computer doesn't care. it just matches engine rev to drivetrain speed when lever enters gate.

so yes, the car does rev match on upshifts.

it does. push your clutch in and get it ready for the upshift, you will see how rpm is kept high to prevent it from falling

Ahhh really? So it is detecting which gate you have entered to match revs? So if, for example, I did a 1-to-3 shift, it will match the revs for that?

If so, that is awesome and totally eliminates my concern :)

Should be no concern. The system has been out since 2009 with no real problems. Plus if your getting SRM that means your getting the Sport package and we all know the sport package is the best option to get on the Z. :stirthepot:

Yes it detects the gate before actually shifting into gear.

:iagree: If you push the clutch in at speed. Then bump the different gates (without entering the gate) you will see the rpms try to adjust.

nissan has done your thinking for you, therefore just get it

All are correct. :tup:

I could be wrong (probably am), but it seems that the car maintains the revs for a moment while you are disengaging the clutch and selecting a higher gear. That's what it feels like to me.

Yes, this was already mentioned. It has no idea if you're going to shift up or down initially so it just sets the revs in the middle ground until you pick a gear.

when you are coming to a stop and clutch in to go into neutral, it will blip the throttle as if you were downshifting. i had some ricer think i was revving at him at a light because of this. :shakes head:

Easy fix, just don't do that :) Just leave it in gear until you are almost stopped and there is no issue.

Thanks for all the info guys - now it's just back to the haggling game with the dealer. They were telling me the leftover 2010 I am thinking of buying is worth a lot more because there are no 2011's available due to the Tsunami, and that a 2010 is worth the same as a 2011 because they are both new cars :).

That's all true, right?

:stirthepot:

Will depend on the dealer. There is definitely a lack of inventory but some dealers are still willing to deal. Do a search on cars.com for 2010's and check out the prices. Many are discounted or at least were.

yep thats what im doing now :tup:

It's going to vary by location, but in general it's true that the Z's are in short supply. Short supply = more $$$. My dealer tells me that there are no 2011's to be had around here, mine came from 400 miles away. I don't know if the 2010's are going for 2011 prices, but until (and IF) the 2012's start getting here in number and the backlog orders for those that lost their ordered 2011 to the tsunami are filled, I'll bet you'll be paying a lot more for 2010's than you would if there had been no tsunami.

As to Synchro-Rev Match, it's very cool and a great addition.

there are no concerns
 

if Top Gear didn't have any problem with it we're good to go

Wow, I was just kidding about the price thing :)

These cars seem to be sitting on dealer lots for months... people are saying in the buying forum that the going price is $1000 under *invoice* for a 2011. I have a verbal agreement from my dealer to sell the 2010 I am looking at for $3200 under invoice.


We shall see how it goes - don't believe the dealer hype that these cars are hard to come by - no way. Nissan is doing $2,000 rebate to the dealer through July 6th and 0% APR for up to 5 years on financing. They don't do that unless they are hurting to move the cars. It's nothing against the car, I think it appears to be the sporty car deal of the decade, but reality is they are selling way below invoice.

Meh..just drive it like you want, regardless of what the ricers or anybody else thinks. In the end, you're the one that makes the choice not to race. :tup:

I will admit that the SRM has scared the fvck outta me a couple times when I was in 4th, reaching for 5th and accidentally pushed it up to the gate that would've taken me into third! My zed responded immediately with a WOT shriek and I very nearly spilled my Orange Shasta!:ugh2:

LOL. That used to happen to me to. Scared the crap out f me.

I bought a 2010 model new on March 27 of this year, which is the dealer's year-end, I believe. They gave me a discounted price of $3000 less than MSRP because they wanted it sold before year-end. It was the last 370Z they had, plus it was exactly the trim model I wanted, Base/Sport in Black Cherry with the mudflaps.

With that said, another dealer ship within a couple hours distance has 3-4 2011 370Zs all sitting in their lot. No point in my opinion to get the 2011 when you should get a 2010 for a discounted price. Don't let the dealer try and talk to you into paying MSRP for a 2010 now - when you go to sell the car no one will know it's only been used for 1 less year, they'll just see 2010 model year and it hurts your resale value. If you scan the forums here you'll see there aren't any major anticipated changes to the 2012 model year, so you're guaranteed to have a "new" appearing Z for at least 1-2 more years if you buy right now.

And by the way, don't even consider buying without the Sport Package...the car should have never come without it.

The rev matching is as close to perfect as its going to get IMHO. You can throw it in any gear AT ANY GEAR and the down shifts will match perfectly. But it doesn't mean its OK to drop it in a lower gear that's out of range. Some including myself, will say that it seems to match up shifts. I say this because, when its off, my up shifts don't feel as smooth as when it's on. How it does it?! I dunno. But I also think there are sensors in the gates. The computer will calculate and bring the revs up as soon as you trigger one of them. Then you drop the clutch and mash the pedal. It will do it all day without fail.

As I said, it's going to vary by region. This region...short supply. YMMV.

Turned off the SRM the first week I got the car, have not used it since.

alright the purist has spoken we all knew it would happen, now yes it does work flawlessly and that pisses off some people who think they are better than the machine. If you hold the gas down it still powershifts, if you don't it still engine brakes, when you push the clutch in with the shifter in a gear it will hold rpm's for you until you move the shifter incase you let the clutch back out, when coming to a stop i just push the shifter to the right (not in any gear) and it won't rev at ricers or the police and old ladys, (you can actually rev the engine while driving through town just by bumping the stick to left should you see something to rev at)

I had one small problem with the syncro rev system: it doesn't seem to rev match when downshifting from second into first. This was only an issue in autocross.

I bought my 2010 Nismo last month for about a grand into the dealer holdback. 2010 will save you some coin if it's all the same to you.

Ummm the only time I shift into first is while at a complete standstill. I don't think Nissan intended for us to downshift into first while rolling.:confused:

Works for me. Never do it on the street but in auto-x I've used it a couple of times when they add in a turn-around.
