Better With Synchro-Rev Off?

on street you can just do a ball of foot on the brake + side of foot on throttle pedal. in fact i do this on most of my cars (less z since i use SRM) unless im really on the brake and swing the heel around to setup the turn.

Ah ok, I'll give that a go.

I thought I was going insane. But I've been driving on/off VDC and VCD=OFF gives way smoother shifts, night and day difference.

I know it sounds nuts, but I don't care, it is true because I've tested it for a week straight.

I agree 100%, i also think that this car learns how you drive and adjusts, when you turn on VDC after a while it seems like it didn't make any difference then over time its starting to suck, then you turn it back on and its all good again...at least it seems that way to me, especially iwth 1st gear

I turn it on I turn it off I notice no difference. I guess I just know how to shift.

I didn't get the sport for the rev matching I got for the cool wheels and spoiler.

sorry to jumpstart this thread again but ever since i got my Z, the SRM doesnt feel anywhere as near as accurate as in the brand new demo cars i drove in the lead up to buyin mine second hand.

If any of you are keen for a little diy tinkering, let me know and ill give more details so we can collect some data here.
My thoughts are:
- Auto transmissions rely on input and output speed sensors to calculate a smooth shift
- Input sensor in our transmission would be the crank angle sensor
- Output speed sensor in our transmission is the one on the left side of the tail end
- If one of these sensors is not sending the right signal in a car with auto trans, sloppy shifts occur.
- My finger has been pointing at the output speed sensor for a while but cost and lack of availability here has put me off buying one and swapping it out.
- There is no SRM diagnostic and no SRM specific DTC so even if this sensor were to fail, all you'd get is S-mode error displayed on the cluster, afaik anyway. If any Nissan gurus have other info, that would be awesome. Maybe Consult has a menu for SRM?
- This is why i rule out my crank sensor because it has never spat a code for it, and the engine runs fine

I love the SRM and always keep it on.

Simply great for downshifting through a corner.

However, when coming to a stop I don't bother to downshift anymore, I just keep it in gear and disengage the clutch when the RPM's approach 1000. I find that with the SRM you just don't get the compression braking to make it worth putting the extra use on your clutch. I'd rather change brake pads than a clutch kit.

that's why i never keep it on. mines always off

i use 3rd when coasting to a stop. considering ive NEVER had to change a clutch on a car that i bought new (or used for that matter) i dont think there is any noticeable premature wear.

I like to shift to second so I can hear the revving... it makes me happy

=( now i'm getting paranoid before my trip in july that I plan on putting around 4-5k on towards the east coast.

you and 90st are probably seasoned drivers (i'm sure others are aswell) but for me i'm like... noob to manual so I've probably put my fair share of wear n tear.... guess i'll start looking at a quote for the HDCSC + Master + labour.... me no so good mechanically

Since the SRM has already increased the engine speed to the right spot electronically the output shaft does feel the resistance of the engine from the increasing RPM and therefore the vehicle does not slow down any faster than if it had been in neutral the whole time.

Hope that makes sense, almost confused myself a bit there.

well that makes sense, after you go

you should fine. there are a couple of people on here that did 5,000-10,000 mile trips with their Z's with no problems
