Hi Guys,

I got my first ITCC race on Sat 9 June. I'm racing a Nissan Skyline GTS--t Type M running 271hp/1100kg (as per regs). I've been running tests the past two nights and I'm still 1-2 seconds off the pace @ Grand Valley East Reverse.
I know there is a thread for all the tunes available but, I can't find a circuit tune for this 'Liner.
Maybe I need to adjust my driving style ...(very aggressive):guilty:
Any and all help is appreciated ...

I was just waiting for you to post the shiny. :lol:

And yea, I've got a few of these R32s lying around and too much time to kill, so post the full settings and we'll see what we can all do to help.

Also, "1-2 seconds off the pace" isn't quite enough detail. What are your current lap times, for a start?

Sorry for the double post ...

Guys are running between 1:07:xxx and 1:08:xxx on GVE Reverse.
My best time was a 1:09:058 on a very hot lap.

Hmm…mind giving me a link to the thread? I want to see what regs you're running under.

What tyres are you using? Sport softs or racing hards?
 
Car feels stable but hardcore understeer on corner exit.
A little twitchy on corner entry but gets to grips in no time. She lets the rear tyres go every now and then (which is not often) but once they gain traction she understeers like a slingshot.
Speeds not the issue. Top speeds on the straight are averaging 220-230kph for all.

Not too surprised, actually. I should have known that much about the car from just looking at the spring rates…I'm being a bit daft today, it seems. :ouch:

I'd either flip the spring rates around or have it at something like 7.5/9.0, maybe even higher. Don't fail me again, guess tuning…

Also, I noticed that the regulations are fairly loose, you can run any parts you want as long as it's within the power/weight boundaries, right? If so, ditch the close ratio 'box and get a fully customisable one.

As long as its in the power/weight boundaries its legal.
I've got the FC box installed in the car, but I have absolutely no clue how to set it, that's why I've stuck to the close ratio box.
And for interest sake, the best weight distribution I can get with the car is 53/47.

Get the F/C 'box, and use the simplest gearbox tuning method known to man. Well, to me, anyway.

- Top Speed setting -> All the way left
- Final Gear setting -> All the way left
- 6th Gear/Top gear -> All the way right
- Try to make all the rest look linear to 6th.

Eh, I've not got a usable version of this car, so I'm persevering with a R32 Type S '91, quite a few differences, but the chassis should be similar enough to get an idea as to how it drives for you.

From the looks of it, if you're understeering, reverse the spring rates as Onboy said, set a lower front roll bar number than rear roll bar, and set negative rear toe to about -0.10, see if those help. :) I would set front brake balance lower than rear too, although that might make the rear step out under braking.

Guess tuning ftw. :lol:

Anyway, I ran your setup, RS tyres with a Type S, slight difference in power and weight, but same weight distribution, 1:08.947. Nothing seems to be obviously wrong with how it drives, however, there is the understeer you mentioned, mainly coming out of that last corner. If you want to fix this through your driving, short shift into a higher gear.

Also, gearbox. Set the final gear to 3.600 first, top speed setting to 112mph, then set final to 2.500. Top speed might be a bit too low, being 155mph on my car, but GVE doesn't need that high a top speed.

:)Good to hear that its the car and not the driving lol. I will definitely try the short shift when I'm on testing tonight, and the gearbox setup sounds feasible.
Thanks Onboy ...

Eh, news gets better. I detuned a GTS-Type M to your required specs, applied the tune with the new gearbox, 1:07.514. :lol:

Ha thanks, so you running the 7.5/9.0 springs?Do you mind sending me the setup so I can test it?

:ouch: Ahh damn ... back to Racing 101 I guess ... Thanks for the effort anyway Onboy ...

Well, if there's no qualifying, then you shouldn't be so worried. We all drive that bit faster than harder than we should do when there's cars to chase, so you'd make up some ground there.

What time is the race, if you don't mind me asking? And you should try flipping the spring rates regardless, since the car needs to fit you, not me. :p
 
Plenty of advise for you to be getting on with..!!

If it were my car, I'd look at lowering your INT on the diff, 40 seems high to me (I'll await a slap from OnBoy, I don't like high numbers for my diff). I'd also look at increasing the front spring rate. I know the others have suggested flipping them and what-not, try everything 👍

Your front toe might be loosing you grip on corner exit, trying reducing it a little. Follow the above advise for rear toe too.

Also adjust your brake bias to the rear, as suggested above, this will get you into corners better and hopefully improve your line for the exit.

Finally, take all OnBoy's suggestions for the gearbox. If you fancy though, you can also use the following method too.

- Final Gear setting -> All the way right
- Top Speed setting -> All the way left
- 1st Gear -> 20% (consider each ratio as 0-100% on the slider, ignore the actual numbers and just use the segments shown)
- 2nd Gear -> 30%
- 3rd Gear -> 40%
- 4th Gear -> 50%
- 5th Gear -> 60%
- 6th Gear -> 80%
- Final Gear setting -> Adjust so that "Max Speed" is about 10-20mph above your actual max speed on the track, maybe a tad more. This gives you some drafting speed, should you need it.

You may find that 20% on 1st gear bogs down on a grid start, so you may have to up it to 30-40%. I've found that keeping all gears, bar 6th, within 20-40% gives you good access to power. Bump 6th gear (or whatever your last gear is) by 20% or so.

Good luck, let us know how your testing goes 👍

Unfortunately its a 3 round event, and first round grid is based on Qualifying. Its all good, cuz this is my first sanctioned (proper) online race, so I'm looking forward to testing my skills against other drivers. I'll be happy with a qualifying/race finish of 10 maybe 8 position.
Not expecting to much, just trying to be realistic.

Race should start at 22:30 (CAT) ...

Eh, actually, I'm not too sure about the LSD now…I always thought that higher meant looser…but it doesn't seem to be the case anymore…I'm so confused by the LSD. :lol: Awaiting slap on the wrist from MCH. :lol:

Eh, that works, but it's better with actual numbers. Taking that last bit into account, the basic gearbox settings should be:

Final Gear- 3.650/2.500
Top Speed Autoset- 112mph

No tyre wear, right? If it's on, then we need a rethink.

"The race settings will all be set to the most realistic settings (Boost: none, slipstream strength: weak, grip reduction: real, tire/fuel wear: ON etc.)"

Tyre wear is on ... :nervous:
 
May I chime in? As far as the LSD goes, might you try 15/28/10. And maybe try extention dampers 8/6 compression 4/9. But just guessing :dopey:
 
Thanks for all the help guys. Some good ideas to tweak.
The only problem is I'm stuck @ work and I can only get testing at about 18:00 CAT.

Less extreme on the toe and raise the car a bit, as well as less camber, basically.
