GT40 TT - 1:22.512 - 90° ATM

BB-5

AT doesn't help in this event since the climbing sectors have to be driven by 1st gear.
Unfortunately AT, with my driving style, was frequently using the 2nd and loosing a lot of time.
So the I changed tracklines and braking points in order to get the 2nd-to-1st AT downshift around 92kmh.
Not perfect but reasonable trade-off...

Ciao
 
Re the high front low rear... it’s been a tuning glitch since GT6... Increases top speed and reduces under steer... top speed effect has been there longer.

Completely unrealistic. Shows up some fundamental issues with the physics engine. I would think they are too complex for PD to fix without completely redesigning the engine.
 
I guess this is my limit

Are TT final results available somewhere or do they erase 'em? Just to check if I ended up below #1000... :D:D
 
Thankkkkssss!

Played LeMans 330 P4 TT on cockpit view w/G29 and manual gearbox, couldn't do better than 3:39:317, gosh... What's everybody here's method so to speak?

1. Use praiano63 car setup
2. Watch one of the top replays, try to keep in mind racing line, gears, braking points, when to use half acceleration, trail braking etc.
3. Memorize your sector time and try to improve each sector individually
...
5. PROFIT! :)

P.S. Changing the view could help also
 
Thanks, I will, except maybe cockpit view which I love sooo much...;);)
Problem was too, I actually didn't own a P4, far from it, just rushed one BMS after another to reach 20m having discovered it on youtube last Wednesday by sheer luck... I finally did it on Sunday April 5 late night, thus trying TT barely 3 days, and learning the car straight into it... Gonna spend a whole lot of time at the wheel of this beauty for sure!! Cheers :gtpflag:

Really don't think I gained $20 million worth of fun in the P4, mostly it was aggravation. I for one am glad it's over.

Now I await a decent tune for the 180.

You can use it in the GT League pro nostalgia race at Circuit de la Sarthe for a fun way to earn some Cr. back, but getting clean race bonuses can be tricky. :crazy::scared:
I enjoyed doing that a few times with the power bumped up a couple or more notches and no need to use the 'aggro' rake settings. :D

Thanks mate, did a couple of laps in the Nostalgia race and added 2 X $160,000. Yep easy money, the only thing I changed apart from the power was the FG.
Then I decided to have another crack at the Lewis Hamilton races, Nurburgring in particular, haven't finished Golding all the others yet though.
And after a hour or two at it I Golded with 5:45.101.

Then Golded Brands Hatch, 4 left to Gold now.

Did I read that right?
Power/Weight Limit: 448hp/792kg for the 180?
Click to expand...
Yep. But also:
Other than that, tune the car how you wish — though it’s unlikely you’ll reach the game’s stated power and weight limits, which seem to be glitched remnants of the previous Time Trials.

I’m thinking of using zero camber nor toe for the rear wheels on the 180, but having a bit of camber on the front wheels, so that it has more grip, and/or maybe using some toe-in on the front wheels, as well. Is there advice that I should do otherwise? I want to configure the suspension to have as much grip for rear wheels as possible, given that this car seems prone to over-steer and especially given the power/weight “limits” for this time trial.

I’m also unsure of how I should configure the LSD. I can’t even say I know how it works, let alone what I’d be changing if I moved to the full-customize LSD. I mean, if the car is prone to oversteer, wouldn’t I want the setting that risks more understeer to compensate?

I also have no idea what to do with the other parts of the suspension, like the anti-roll bars or the spring frequency.

It almost makes me wonder if tuning is just an afterthought for PD, and they’d rather focus on stuff like the driving. Hopefully they’ll fix the reverse rake exploit in the next game, and fix (or add) a bunch of other stuff while they’re at it.

For example, I like the idea of each car having realistic transmission types and assists when driven stock, complete with a way to map a button for the clutch.

EDIT: If PD was smart, they'd be taking notes from the tunes being used for the Time Trials and fixing the tuning issues, either in an update for GTS, or in the next game. What a joke, for GT to call itself "The Real Driving Simulator" when it still has issues like this. I can only hope the larger staff will help with these issues when the next installment comes out.

I wouldn't put too much faith in PD. If they can't get it right in 20 years, slim chance they can rectify it for the next game. I'm pretty sure Kaz knows this glitch, but he chose not to meddle too much with physics development because that isn't what Gran Turismo is about (despite "The Real Driving Simulator" tagline would have you believe). The series at this point is riding on brand recognition, being a graphics showpiece for every PS generation and spearheading the esports wave. Fixing the physics from the ground up would require lots of coding, testing, and rebalancing of all the cars. And for what? The major proportion of GT fanbase wouldn't even notice it. The FIA races are all fixed setups so it doesn't affect it either. It's a huge time/money/effort for not much benefit.

Compared to the true sims (e.g. AC/rF/AMS/iRacing/RRRE/LFS, and to some extent PCARS), where their entire premise is on delivering the most authentic simulation possible, if they mess up physics they will lose their core fanbase quickly so it makes sense for them to spend lots and lots of time getting it right. But for GT's purpose, I suspect Kaz believes the current physics approach of being good enough for 90% situations is adequate.

BTW, regarding tuning help, I would advice you to read up on the basics. Asking scattergun questions in lots of different parts of the forum will get you nowhere. Here are a few threads to get you started (yes they're older games, but the basic principles still apply):

https://www.gtplanet.net/forum/threads/m-specs-pocket-guide-to-gt3-suspension-tuning.28326/
https://www.gtplanet.net/forum/threads/gt5-tuning-guides.135268/
https://www.gtplanet.net/forum/threads/general-tuning-guide-updated-1-09.297354/
https://www.gtplanet.net/forum/threads/gt6-tuning-guide-1-15.319562/

Once you understand the basic principles, test them out yourself by experimenting. Once you do that enough you'll figure out tuning by itself eventually. When I started back in GT1 I didn't know anything either, but through many years of experience I can get a car to 90% of how I wanted it to behave. The real talented tuners like prairano can get a few extra tenths more, but even a basic tune is better than nothing at all. Also don't forget the actual driving technique itself can get you a huge laptime. Tuning is just the cherry on top. I myself always practice on default setup first. Once I hit a wall, then I start tinkering 👍
 
Perfect analysis... Have to say with a wheel GTS is satisfactory enough... Even not being an exact simulation (that really attracts a minority anyway, though maybe the 'important one') the driving feel is now at a very good level, and the whole enviroment is crafted in a way that somehow compensates [some lack in accurancy], an excellent mix of realism and fun which hits the jackpot apparently... AC for PS4 has got nowhere near the same graphics (don't know about PC) so yeah, car behaviour is nearly perfect but more often than not it doesn't catch your eye somehow (sense of speed first and foremost)... What PD should improve dramatically is AI behaviour and challenging, we keep praying for that since day one, here's hoping the power of PS5 would allow it (together with their own will... :banghead:) Online department, for which the game was 90% conceived, is fantastic on my part... 👍👍:gtpflag:

Haha, I suppose it's still technically "The Real Driving Simulator" and not "The Real Tuning Simulator." I honestly prefer learning more about the racing/driving part of things more than tuning, anyway. I mean, I think part of the fun of tuning, at least for me, is testing your own tunes and at least getting a basic enough tune so that can compensate for some characteristics of a given car, such as oversteer or understeer. I don't think it's as fun when you simply copy somebody else's tune. That said, it's fascinating how much of a skill ceiling there is to events that permit tuning, like the time trials. I often find myself within the top 1000 or so even with some minor changes, like to the gear ratios. But I suppose it's also very much like you said, where a good tune enhances a good driving line, but can't replace it.
 
Some success with the Laguna TT. Was In 10th earlier today (1.36.9), but still a second or so off 1st.

Running max front, min rear ride :rolleyes:, with maxed springs, shocks and ARBs (to minimise weight transfers), toe 0/0.05, camber at 2/2, diff at 60/60/5, and a super short flipped transmission (but don’t think gearing makes much difference as top 10 are using very different ratios). Changing up early (c.6.75k) and short shifting to minimise wheelspin on corner exits. BB at 0.

But this car has so much power vs its grip that is more about brake and throttle control than fine tuning the settings.
 
My fastest time at the Ferrari 330 P4 Super Lap was 3:37:000.. Now I'm entering the Nissan 180SX Super Lap.
 
Don't know how exactly I got up so high in the rankings, never did it even into a thousand. Of course, there is one more week to go, but still a very good result for me.
Maybe it's because it's my first time using manual and not auto, although it doesn't seem like that could give such a boost with this car/track combo.
