Nissan GT500 GT-R '08 Nurburgring GP/F tune

[jucksmanBR]

Hello, Guys!

Can anyone help me with my tune? I'm preparing my car (a Calsonic Impul GT-R '08) for an online championship, and have gone as far as I can with it.

With 503hp and 1100 kg my best lap at the Nurburgring GP/F has been 1:53.9 with no aids and my average lap time is 1:54.5.

I've seen videos of people lapping at 1:51, 1:52 with these same specs and I know I'm absolutely at the limit of the car with this tune, so I assume the biggest part of the time gap is due to a better tune.

Here's what I got:

Aero: 40/65
Tranny trick to 290 km/h top speed
LSD: 8/60/5
Suspension:
Height: -2/1
Springs: 16.0/13.0
Extension: 8/6
Compression: 4/6
Anti-roll: 4/6
Camber: 1.8/1.4
Toe: -0.10/0.10
Brakes: 5/9

I'd normally rip my skin out rather than say this, given how much I hate the R35s, but this is as damn near a perfect tune for the Calsonic R35 as you'd find on here. It actually drives well…and I want to die now that I've said that.

If that doesn't work all that great online, try this and this and finally this. 👍

Thanks! I've tried the last 3 tunes you linked, but I didn't know the first one. I think I'll take a look at it and make some comparison runs. :-)

Oh? If so you'd probably find that it might not be as good then, since it was tuned for offline rather than online.

Have you tried all the ones available, if not, try this one as well.

You sure have a lot of info on the R35 Onboy

You must know your rivals, inside out, in order to have a hope to bring them down.

I have much to learn, oh wise one

Okay, sorry for hijacking you thread. I'll leave now

Eh, I've just started.

No, stay, I ain't going to touch the set up sheets on any R35s as of now. You do tuning, I do the bull:censored:ing.

I told myself that I wouldn't tune another one after the ToF shootout, but....maybe

It would be near impossible to make one better then the ones you have listed though

Praiano's tunes are great, but oddly enough they didn't suit my driving style at the GP/F...I tried adapting those, but the car only got slower. I'm a very agressive driver, so not every tune suits me...

 

[jucksmanBR]

Does anybody have a personal online tune to share?

 

[CyKosis1973]

Have you tried CSLACR's..?? He's been banging out the GT500 cars recently and there's only one of his cars that I've driven, to date, that I didn't like (and he took the time to do me a custom set of dampers for that car, so)...

[jucksmanBR]

I'm actually using his tune right now. It feels good on track, but I think I'll have to induce some oversteer into the car to help cornering..

If you're using the one first linked for you (https://www.gtplanet.net/forum/showthread.php?p=7097930#post7097930) and you want to induce oversteer, there are 2 quick and easy ways to get it.
A: drop the rear ride height. He's got 5/10 on that setup, which I call a 'rake' of 5. On GT-R's I only run a rake of 1-2 based on how much power you have. The more rake you run, the harder you can stomp on the gas out of a corner, without experiencing wheel spin. Try 8/10 or 9/10 and see what happens. If corner exit gets a bit sketch, go back to 6/10 or 7/10.
B: Add some negative rear toe. Not a lot, but -.03 to -.08 should help.
C: Just noticed, his LSD DEAccel is at 9, GT-R's are pretty stable, I'd drop it to 5 and see how you like that.

You probably don't want to do all 3 of these at the same time.
Do A, then C, then B, until you find the balance you like.

Thanks a lot for the suggestions, Adrenaline! Now I have a whole new car in my hands, lapping in 1:51.2. Also, my soft tires lasted for 9 laps while testing in my online lobby... :-)

Probably just a lucky guess.

- Update: sadly, I've lost my final tune, so back to square one... :-(

Did you lose it, or is it the one you sent me in a PM to fix? I'll run some laps later today, but if it's the setup you sent me in PM, it has major flaws, that can easily correct some of your issues.

This is my base setup...I lost the finished one, that you helped me with and now I just can't find the right direction again...

 

[Adrenaline]

I don't know... It seems pretty simple. Read post #14. It has the link to the 'base' and then includes all of my recommendations, of which you seemed to be happy with.

Regardless, here's what you PM'd me:

This is my current tune:

Downforce: 40/65
Transmission set to 280km/h

LSD: 8/10/5

Suspension:
Height: -15/-13
Springs: 15.1/13.4
extension: 3/4
compression: 7/5
anti-roll: 6/4
Camber: -1.0-1.5
Toe: -0.00/0.50
Brakes: 3/1

All aids off. Abs 1.

Biggest issues:
- Understeer at corner entry
- Snap oversteer under hard acceleration
- General lack of grip

Here's what I would blindly change:

Downforce: 40/60 (Less Rear, personally I only use 40/50)

LSD: 7/10/5 (Helps with some of the sweepers. The Accel depends on inside/outside tire spin, can't know without driving, unless you tell me.)

Height: 9/10 (Positive ride heights, not negative, way too many curbs.)
Springs: 15.1/13.4 (Try increasing both by 10% in isolated tests from the rest.)
extension: 3/4
compression: 7/5
anti-roll: 6/4
Camber: -1.0-1.5 (I'd probably go 1.0 front and back, but this is more fine tune based on feel after other tweaks. More rear camber usually means a more stable rear end of the car during the center of the turn, less and you can induce some oversteer rotation.)
Toe: -0.00/0.00 (+50 in the rear is horrible, front toe is a fine tune for corner balance. - for better turn in, + for better exit.)
Brakes: 1/3 (Rear bias, so you don;t overload the front tires on entry, aka understeer at corner entry)

Congratulations, Adrenaline! You've been elected my official race engineer...lol

I used your tune and the car feels much faster now. However, I couldnt translate This speed into improved lap times:

- the car feels over responsive now, so its very hard to be consistent. Its too aggressive at turn in and i cant easily find the apexes at turns 6 and 7
- still have some snap oversteer exiting both these corners, but I think its due to the cars over responsiveness.
- a little too much wheelspin exiting turns 1, 3, 4 and at the last chicane.
- still unsure about transmission settings for This track. The final speed at both straights is about 255km/h...what do you suggest?

 

[Adrenaline]

Toss me your current settings so I can see where you actually ended up with your current version.

 

[jucksmanBR]

I used only the settings you posted yesterday - didnt want to fiddle with them too much and ruin the car again...

 

[jucksmanBR]

Best lap: 1:53.7 - found major improvement with this tune. I still feel that there's more grip to come from the suspension and I'm still not 100% happy with brake balance - I wanted to be able to 'dive' more into the corners - but the snap oversteer is gone and traction is much improved...

Things I'd like to improve:
- A little more mechanical grip
- Better braking - i.e: braking later

What's your tire wear look like?
On corner exit, which tire is spinning? Inside or Outside?

Tire Wear is about 5 laps with racing softs, mostly because Im still not being very smooth. Inside tire spinning at

Do i keep aero at 40/60, or bring it down?

Camber: 2.5/1.5
Toe: -0.20/0.10 - -0.08/0.00
Brakes: 3/6 - 5/6

Modified.
LSD might need raised a bit higher from 12 yet before both wheels let loose at the same time.

Do i keep aero at 40/60, or bring it down?

Probably 40/65 unless it's PP regs, in which case 40/55 is probably a good high aero starting point.

Did a quick test this morning and the car feels very good. The lap times were not significant because I didn't get into the groove, just cruised a little and felt for the car's reactions.

I will make a more through test tonight, but it's looking good! :-)
