[Cats_PJs]

First I have to thank @EDK for the new tune, it made a huge difference. I did change a couple things, it was just too hard to keep pointed the right direction.

Toe 0.0/0.0
Brakes 2/2
My gears
LSD 5/60/7

New splits

24.765
55.149

Still getting the hang of t2.

 

[EDK]

First I have to thank @EDK for the new tune, it made a huge difference. I did change a couple things, it was just too hard to keep pointed the right direction.

We were just doing some testing for the online race this Saturday, and I ran some with this tune and with my first tune, that a couple of the guys were using. First tune is definitely more stable, this one is faster.

Were you having trouble keeping it pointed in the turn 1/hairpin, or other places? I kind of just chuck it in there, let it do what it might, and adjust for the exit. Did experiment with some different BB settings, even, and also front bias. But landed back on rear bias being faster for me.

I'm normally not the "loose is fast" guy, but this might be an exception.

 

[Cats_PJs]

Yeah, that first hairpin was tough and the final chicane. It was even squirrely in the fast right in t3,quite the wild ride. Good stuff though.

 

[mr_lab_rat]

Working on a much milder tune.

24.917
55.167

.3 at the line.

The lap was still far from perfect. I think most of the gain came from the tune. I could probably get two more tenths out of it if I drive better

 

[Mamba]

Let's do a quick survey.

@manumanu19 @Doodle @RS__96__oO @kreezydoed @jonjig

are you all running with or without the rigidity and which tune? Your own, Kevins, Mine, Kevins and mine combined, or Safeways? If running a public tune, has it been modified a certain way?

Running it's the wins tune the original one played with ride height but ultimately came back to 62/62 changed front toe to -.15 that's the only change I stuck to. Btw no rigidity yet

 

[mcsqueegy]

First go:

24.809
54.981

Using a low downforce setup is quicker if you can nail the first few corners, i found 2 tenths to T2 but couldn't improve overall time

 

[mr_lab_rat]

I think I'm done for the day. I did the body rigidity thing. Doesn't seem to make much difference.

Got better splits but not much time gained at the line.

24.900
55.083

 

[ItsAllAboutWins]

Thanks @Doodle and @manumanu19

It appears that no rigidity may be the way to go.

no rigidity, put a tune of my own. i can post this evening if you guys want, but don't know if its any better, haven't tried the others. I know i have negative front toe like manu, nose up, but more downforce than most it seems (max front and 290 back). it helps me a bit for the last chicane

Its up to you if you wanna post it. I was more curious about who was using the body rigidity. Thanks Koen. Glad to see you back this week

[Thematic]

555 km in, probably submitting next but not sure about satsun/mon yet. First "session improvement" was a forgotten time, then decided to do another consecutive lap from just 154 kph and landed at minus half a second.

Used EDK Tune 2.

25.152
55.935

 

[iainoflo85]

I think I'm done - despite finding a tenth in sectors 1 and 2 I'm still 2 tenths down at the line on my best lap from today.

Somehow the 24.xx sector 1's seem like an impossible dream for me, I cannot see how it's achievable at all - closest I've got is a 25.09 and then had a 55.40 so I know if I can gain time in sector 1 it will impact my sector 2 time and perhaps a faster overall time, but I cannot get a 24 T1 no matter what I've tried - does anyone have some advice.

Still using the same tune - tried EDK's version 2 tune and couldn't get comfortable and I found it slower for me rather than faster, even with Baron's adjustments.

For T1 I go full throttle untill the curb on the left (stay as far left as you can), that is also my turning point, you can be aggressive there, then control the brakes for a nice turn in (I use first for turn in, and shorshift to second to accelerate out).

Don't go to wide in the hairpin, take it short, you will go faster with a wide line, but it takes to much time. Avoid the curbs coming out of the corner, it unsettles the car and cost you time

Hope this helps you a bit.

No rigidity, ItsAllAboutEDK tune, down force changed to 80/90.... submitted my time on Tuesday Wednesday (lol) and haven't had time for another try with any other settings..

 

[mr_lab_rat]

I do go wide and deep into the s1 hairpin. Yes, it's slower but you get it back in s2 by being faster down the hill. I have seen 30.0xx sector times.
In the end I end up with the same T2 so I don't think either method has major advantage.
It could be different if you run much lower or much higher downforce.
I'm at 100/120 now.

Yeah, a lot of it does come down to the downforce you are running, which I'm pretty well convinced is down to driver preference. I said my 2.0 tune is faster, but what I should have said is that it is faster FOR ME.

I was about 0.5 per lap slower with my original tune, and was losing 1-2 tenths at T1, which I think was mainly down to straightline speed. But another D2 driver running my original tune set the fast lap for the test room. On a half tank of fuel with fresh tires, but still, was an impressive lap.

Once you alter DF, you have to change the suspension and LSD to make it match. So just find a tune that fits your style and start grinding out laps. 👍

Running without rigity improvement, low downforce and itsallaboutEDK tune.

Btw, i just realised i posted the wrong splits these are the correct ones:

24.762
54.912

 

[Thematic]

Slightly slower first, but third isn't bad at all.

25.183
55.666

Nice splits. 👍

--
Hope this helps you a bit.

This. Adopted as my braking point and gained consistency for the corner. 👍

 

[iainoflo85]

Thank you @kreezydoed somehow it helped - I was braking at the start of the rumble there, this time I lifted and flung it through that first bend and braked hard. After a few attempts I still couldn't find a 24 - I got .005 though once. Then I thought I'd change the downforce - used @mr_lab_rat 's 100/120 DF and combined it with the kamikaze first sector and got these splits after some time for a .07 gain at the line:

24.897
55.331

I think perhaps I really am done now, but I'll keep going regardless in hope of further improvements - perhaps I could get another tenth in T3.

 

[Bertracer]

You keep mentioning my tune but I only shared it in a private conversation
It's no secret and very basic:



I hope I didn't break fetchy with this

Sorry mate!
About to give it another go with higher lsd settings and get that thing sliding under throttle a bit more.
Anyone played with a bit of rear or front end ballast bias? I'd have thought we'd lose time unless can fine something that really helps in the tight corners.

Didn't even notice ballast could be adjusted.

Every tune on here seems to be giving me the same time, not sure yet which I'll stick to

Didn't realize I had the same time as @RS__96__oO how was your T3?

 

[Carlos Fandango]

Had my first run on this last night. Banked a 55.55x T2 with a nice T3 then went back and ran a 55.3xx, again with a good T3. On review though, I had a barrier touch right at the end of T2 exiting the last right. So back to the track again, and ran a 55.26x but lost a little in T3 to my previous dirty lap to end up hundredths down at the line…at which point I couldn't save the ‘best lap’

So in summary, I’m mid-pack in D2 for now, but need a clean lap to cement. Using the Brandon vs. Kevin mash-up tune that most others are running, with ‘tweaks’ to suit my ham-fisted driving style!

 

[mr_lab_rat]

For T1 I go full throttle untill the curb on the left

I brake and turn in a bit before the curb. I actually keep the throttle on and apply partial brake. I call it "tiptoeing through highspeed kink method"
But my T1 is not very fast (the best I got was 24.85x).
Here is the tune to confuse people even more:

mr_lab_rat's tune version 2.0 (with some of the tuning explained)

85/55 (known trick for reducing FWD understeer)
7.50/5.00 (the car is light and the track is bumpy)
3/2 (again, light car)
6/4 (this is good for bumpy tracks - quickly putting the wheel back on the ground after a bump)
3/3 (I tried everything here, default seems the best)
0.5/0.2 camber (again, a lot of time went into this)
-0.05/+0.05 (I have no idea how you make it through s1 with rear toe out)
3/2 brakes (more aggressive brakes can be probably used but my old wheel is not very good for modulating brakes)

EDK's original gearing but extending 2nd and shortening 3rd should help in s2

7/21/5 LSD
100/120 downforce

 

[Mamba]

24.733
54.850

Lost a lot in sector 3 need to find it with similar splits now. That chicane is so nerve wrecking

Here is the tune to confuse people even more:

Agree with most of your assessments, although camber, toe, brakes, and DF I think are more of a personal preference thing.

I like to keep front toe neutral, as I find changing it causes the car to "walk" at turn in, and I want my turn in to be incredibly accurate. Once I turn the car, I tend to let it do what it will until the time comes for throttle. Accurate trail braking is very important to keeping the car under control between the kink and the back of the hairpin, but as long as your wheel lock is controlled, having the car set up to rotate provides an advantage (IMO). Another way of saying is that I probably am not feeding in nearly as much steering lock as the people who find my second tune unstable or unsettling are.

I might try upping my rear Shock rebound. Agree completely with you on the rebound helping with the bumps, while bound needs to be soft. And on springs, and ride height.

I'm not sure how the rear biased aero is affecting the car for you, I assume it makes it tighter, something I am trying to avoid.
