My Tuning set up for the Nissan #23 GT-R LM Nismo for Nordschleife (Nurburg) (The Ring)

Hi Everyone
I will give you my Tune for the Nissan #23 GT-R LM Nismo for Nurburg. The tune was set up with a steering wheel and peddles using just manual gearing, ABS on and Traction on. I had a lot of trouble getting the rear end to stop stepping out when braking into very slow corners. This tune is the best I have been able to get the car to handle when braking for slow corners. On the fast corners it handles superb. It will take a few laps to get use to how the car reacts, but be careful as the car doesn’t like it if you catch a curb wrong or take the car into the corner in the wrong gear. And you will be able to adjust and tweak the setting to your own preference and driving style. ENJOY!!! I got the time to a respectible clean 6:03.527 with a few mistakes but no fowls.

The largest Restictor Plate

Thanks RDB. It will be fun to try your tune and see what you did. Since I haven’t done that yet, I could be way off, but usually when a car’s rear comes out during braking it means there is too much rear bias. I will move the bias forward to see if that improves. The high speed braking may be OK because the downforce holds it down.

Some of the curbs at the 'ring are huge, so nothing may help. But…usually if a car gets thrown off excessivly by curbs, or rough roads, softer springs help. But then you may decrease cornering ability. If you are tuning for one track like the 'ring with it’s big crubs and bouncy roads, a softer suspension may help.

If you already know this prefectly well, and have already tried it, my bad.

The rear was stepping out with the default settings. Before you put the setings on the car. just try driving it with the default settings and you will see what it mean.

Will do.

DRB, I tried you tune out. Boy, the car doesn’t work stock. Your tune is better, but it has it’s problems. Biggest one is the diff. is set wrong for this car. The car still oversteers at slower speeds, and the bottom hits the ground. I think you had the caster and camber right on. I had one tune in FM6 that worked best with the bottom hitting, but this car doesn’t need it. This car with a nutural tune has wild oversteer at slower speed combined with slight understeer had high speeds. I tuned it and shared it in game. Below is the exact tune if you want to mess with it yourself. Let me know what you think. Same upgrades as you have.

I tried this with a few changes (most notably Differential Acceleration at 40%) and it handled pretty well. It won’t beat the 787B but at least it handles well now. You just need to be attentive when applying throttle post-apex, as too much will cause severe understeer (TCS off).

The huge oversteer at low speed vs. the understeer at high speed is what took a while to tune this car. Finding the right compromise, as I coudn’t find an adjustment where both were fixed, will ultimately depend on driver and track. That’s why I’ve always felt that people who really want to experience Forza fully, should learn to tune. No one tune for any car can be perfect for all tracks and all drivers. I’m always changing my tunes.

JuiceMcGoose1 thanks for the feedback on the setting.

Yeah I forgot about the car being Front Wheel Drive when I was tuning it, hence the Differential settings being wrong. lol.

I tried your settings, but due to my driving style I was still losing the rear of the car on one or two corners. So I adapted my original above tuning and incorporated some of your settings with a little tweak here and there to suit my style of driving.

It takes a while for the rear tyres to warm up so I had to do one warm-up lap, then one flying lap of Nurburg. And with just two small mistakes (but no fowls) I got a clean lap of 6:02.592. That would put me 215th on the leaderboard. But it will not count, as my fastest lap is in the #55 Mazda 787B position 86 with a 5:49.941.

So the end result of the Tune is:

In my opinion this thread is exactly what these forums were designed for…friendly and constructive feedback between members which can positively affect everyone. I’ll be trying your tune(s) out tonight…thanks guys!

Yeah, I don’t think this will be a leaderboard car. Just something different. I can’t drive it in cockpit though.

Agreed; it’s a fun oddity and I have gotten a few Top 100s already (Sebring Short) but it’s no match for the 787B.

I’m finishing up a paint today but I’ll try out some of the tunes here to use as a base for mine.

I’ll have a go at it tonight as well using stock build, mild-near-stock tune that I’ve tried out at LeMans last night. Top speed hurts on this car (compared to other LMP1s).

Are you guys also seeing ULTRA fast fuel consumption? I ran out of fuel in middle of lap 4 at LeMans.

To tell you the truth I have the “Damage, Fuel & Tyre Wear” turned off

Hi all
Just tried the tune out on Le Mans Classic track and I did a time of 3:18.161 which put me at position 108 on the Leaderboards on the “Sorted By Europe” board. The car seemed to handle pretty good. You can view the lap replay to see how I drive.

By the way, why the multiple leaderboards? Why not just have the one Leaderboard for everyone?

That’s a friggin’ fast time at LeMans, let alone doing it in a FWD GT-R LM Nismo!

Also my P978 run at Nordschleiffe was 6:13 on 2nd lap (could not do more because fuel ran out, LOL). At Nordschleiffe your tune, I suspect, would be GREAT, because the default tune was a bit too tight and I felt the need for a touch more downforce.

Why can all threads be this calm and constructive! This is what FORZA is all about. I will try these tunes with my own one handed driving style. Keep up the great work guys.
