Z NISMO discoveries

[PDX_Racer]

Great feedbacks!

How have the RE-71RS been holding up, being they’re not rotatable? I’m contemplating those or A052s for general use plus some track days here, with summers having high temps.

I’m using GY Supercar F1 3R for my track Cayman but those are 100TW, too soft for dual duty.

Thanks.

I got 3 national tours (RedHills, Lincoln, Bristol), 3 pro solos (Atlanta, Lincoln, Bristol), and numerous regional events out of them. I counted that I had over 100 runs before they pretty much heat-cycled out for national event use-but they still had tread. They would probably would have been fine for regional events-but I only had one additional set of wheels, and wanted to have new tires so I could try to not embarrass myself (failed).

The RE-71RSs seemed to handle heat pretty well-right up until the last few runs. Oh, and I do have proof of 1.5G lateral on them (two different courses).

Without turning off Emergency Braking, it's really difficult to get the wheel straight enough for the computers to allow the car to "not kill you."

This probably isn't as big a deal for track use, but for autocross we spend most of the course with the wheels NOT straight.

Interesting... but I’m confused with the Emergency Braking and why we have to disable it because when you go into VDC off it already disables it!? I think I’m missing something here. So you are going into VDC off beyond Traction Mode right and then disabling Emergency Braking in the settings, right? Are you telling me it doesn’t disable in VDC mode even though it’s says it is? I’m so confused and hoping it’s a special hidden feature!

PS: Or are you going beyond the VDC Off mode that locks the VDC from being disabled, the so called Valet Parking Mode?

Well, Nissan doesn't actually "turn off VDC" - they change the tables so that the limits are higher before the computer starts to interfere. Yes, I'm holding the VDC button down for 11+ seconds to go through the TRACTION light coming on then going off. There's a VDC light under the bottom-left of the digital display. When that light goes off, almost everything is "off" (well, the limits are so high that it will be difficult-but not impossible-to reach those limits).

However, apparently turning off VDC doesn't disable the steering angle sensor. Turning off Emergency Braking apparently raises the allowed steering angle.

The course on Thursday had a lot of tight (pin) turns. I was able to use the throttle (gently!) to rotate the car on corner exit.

I’m extremely confused because from what I know we have Sport+ with VDC OFF Traction light on some nanny’s then hold it down again an VDC Remans off but Traction light goes off this is supposed to give you more slip angle. But in saying that the Emergency Braking is off as soon as you enable any of the VDC Off modes, so very confusing.

If you are right though and it that’s a hidden mode then it’s very misleading because that’s supposed to be the VDC button lock mode, the so called Valet Parking mode, so I dunno what to say, but I will say Nissan has lost the plot and this is the most retarded Track toy I’ve ever seen. If you can’t disable everything except for the obvious ABS then what’s the point at all? All this is going to do is frustrate drivers and cause more issue like brake pad wear and even snap oversteer when it decides to brake the outside wheel and throttle cut when exiting a corner on track so what’s the point, but to hurt laptimes? No wonder it gets wiped out by the GR Supra on track when it should be right up there with it, pathetic from Nissan, I’m now thinking I’ve made the wrong choice and wishing I had got a GR Supra instead.

They didn't make it as a track toy. Designed to be a great looking cruiser- which it is.
Reason at track days 95% of the fast cars are Porsche, GM, BMW. Also look at the top times posted at tracks for street cars.

This thread is about discoveries I've made about the NISMO-and how to make it a better "autocross (and track) toy."

Nissan-like all of the other car manufacturers-are beholden to lawyers so they don't get sued into oblivion.

As far as the confusion about why "VDC off" doesn't include "steering/throttle interaction off"-see the above paragraph. With just VDC off, you aren't going to get the car so out-of-control that you're going to injure or kill yourself because too many people will turn off the nannies on the street, and then get themselves into trouble-and maybe kill someone.

Save this information for the autocross course or track. Don't be an idiot and try it on the street.

Very well said, apprec your experiences with the various settings. Try these - most nannies OFF - only in controlled environments, track or autox. The Z is true and true Nissan with the added safety nets for street use, intrusive at times. Like what's been detailed, most can be turned Off. It's not a mishmash of technologies like Toyota/BMW which I know can give sudden snap oversteer easily with everything Off.

If snap oversteer is a problem-even with good drivers-that's usually an indicator that there's an abrupt change, either the computer stepped in when it shouldn't, or suspension hit a bump stop, or some other change.

I'm just going to have to drive the Z to the edge-like they are with the Supras. I'd like it if there were more NISMOs (or even Zs) out there. Come out and play, I've done a lot of the work, I'll gladly share any other information I have.

Verified at yesterday's autocross-disabling "Emergency Braking" in the Driver Assists menu seems to raise the limit on how much steering input can be active when accelerating. I've now gone from no throttle on corner exit to traction control ("blat") on corner exit with the throttle on.

So:

• Select SPORT+ mode
• Hold down the VDC button until the TRACTION and Vehicle Dynamic Control (VDC) off indicator light turn on and then back off (VDC off light is in the Warning Lights part of the instrument panel, below the left side of the display)
• Bring up the menu, select Driver Assists, and turn off Emergency Braking.

Now I can add throttle at the exit of a corner, if I start getting excessive wheel spin, traction control kicks in (spark cut).

Wow I wish I read this thread last night. Was at CMP today and I finally felt confident to try driving without the Nismo traction mode but turns out I misread the manual and disabled everything. I was pushing it twice... I also didn't realize I still needed to disable the emergency braking because I saw it lit up on the dashboard when I disabled the driver aids. I'm probably an idiot but I feel like they could have worded this a bit more clearly... at the top it says to turn on the traction mode perform the following steps...That made me think you need to follow both steps to get to the traction mode

Have you seen any issues with the Nismo transmission not upshifting into 4th and 5th gear using paddles? I had this happen a few times every session. It happened trying to shift early and late.

I'm generally doing autocross, so I'm in first through third most of the time.

The only time I have any problems with the gears is when the transmission is cold, then I get a delay shifting 3 to 4. That doesn't happen any other time.

I have a 2023 Z performance,and my z is manual . Can I use the same steps to close the vdc ?

In the 6sp perf. You can only turn off traction control by holding the tc button for 2 seconds. Or hold the button under the brake pedal. Disabling the pedal switch completely shuts off any form of traction control. Traction control button does not. When tc is off, you get a solid 3 seconds of wheel spin before it cuts you out. It wont get in the way of track activities unless you are drifting. Most of the time, it will be the fuel pump losing pressure due to sloshing out of the corner rather than tc hitting from loss of traction. However I have not tried to disable tc and then go into settings to disable auto braking. It shows the light as off but apparently on the Nismo it’s not actually off, so this might help a bit, I’m not sure. I know for sure that with tc disabled and you try to drift, it will let you swing for 2-3 seconds before the ESC light kicks on and stops you.

thank you very much! So if I want to drift, do I both need to hold the button under the brake pedal and turn of TC?
