Official Nissan 370Z Synchro Rev Match Transmission thread

[Surly]

Looks like this is an old thread, but I have to say I think I prefer SRM off for daily stop and go driving. There's something initally cool about the throttle blip when going from 3rd or neutral to 2nd for a simple turn, but it seems to wear off fast. I feel with SRM off I get a much smoother, linear acceleration and shift from 1st to 2nd.

If I were on the highway I think SRM is great, just not so sure I want it on every day.

My comments may be a bit biased considering 80% of the time I am driving an Acura with a manual transmission, perhaps with it off it's just an easier transition between the two.

^ Very true.

It will just happen quicker if you have S mode on and putting in the clutch while in gear will just return the revs to redline if the rev-match is still working. (unless there is a saftey feature that deactivates this once in overrev).

On the other hand, it could save the day...

Lets say your on track, heavy on the brakes while downshifting to fourth, you suddenly hear engine cut-off (redline) due to the rev-match feature trying to match your engine speed to the road.

"Oh SNAP! I was about to downshift into second and blow my motor!" you say, as you immediately stop and go into fourth instead = Synchro-Rev Match (and rev-limiter) saves the day!

The problem is finding a track guy with a humble enough ego to get use to it.

Every once in a while an automotive technology will come along that has me yearning for it to trickle down into other cars. Sometimes it's a small thing (satellite radio) and other times it's a game changer like the Synchro RevMatch manual transmission found in our long-term Nissan 370Z.

The ease of making rev-matched downshifts differs based on pedal placement, throttle tip-in, driver's foot size, position of the moon, familiarity with the car, and of course, driver skill. I don't claim to be a heal-toeing maestro, but I find our M3 and Mini Cooper S to be incredibly easy ... the Challenger not so much.

But none of that matters in the Zed (which is spelled as such for my fellow Canadians out there). Once I got beyond the initial trepidation of dropping the clutch without matching revs, I found myself downshifting a lot more. At traffic lights, I'll go down through the gears just for the hell of it rather than coasting in whatever gear I was in. Sure, there could be a "lost art" element to this new technology, but I think it makes shifting your own gears more fun.

Now if only it was attached to a more pleasant engine. So here's hoping that the remaining purveyors of manual transmissions develop their own Synchro RevMatch. As Howard Hughes said 1,988 times at the end of The Aviator, "it's the way of the future."

Even though some of my friends don't like the Z but they have all praised about the synchroRev match technology. One of them (who drives a bmw) is totally amazed by the SRM and wishes if BMW would adapt this technology on the upcoming vehicle. I personally love the feature and still haven't turned off since I left the dealer lot. I gotta say, thanks Nissan to bring something new to the table.

AK, I haven't turned mine off either because of it's awesomeness. Is anything affected in the long term by keeping this system activated? I wouldn't think so, but I'm not too technical, so I thought I'd ask.

Does DRM (or synchrorev) work with 7-Speed Automatic using Manual Paddle shift?

Of course. Every automatic transmission by default has "synchro rev match"

You may have misunderstood my question. I know automatics will syncrev and the 370 has DRM in Automatic mode. However, what happens if you paddle shift the 7-Speed Automatic - Manually -? Do you still get the benefit of DRM (or syncrev matching)?

It's all a smooth transition whether up or down. Paddle shifters or not.

Ok, excellent. Thanks for the answer.

Does anyone know yet whether a change in the final drive gear (from the stock 3.69 to say, 4.08) would affect the function of SRM?

[bezzita]

Hmm, with this upshift feature...changing to lighter flywheel wont have much impact then??? Usually most people worry the RPM will drop much quicker with lighter flywheel and it would be harder to shift-up (have to shift quick enough) so the RPM wont drop that much...?!?!

[kannibul]

FWIW, synchro-rev works on the 7AT, I noticed it today on both ends - downshift AND upshift.

[shabarivas]

synchro rev does not exist on the 7AT - you have a torque converter

LOL - ok, try again.

[ImportConvert]

I loved it, except when I shift into neutral I waggle the shifter to ensure that it is not somehow still in gear. This drives it crazy. I know, it's a personal problem.
