Bought the Mustang.

Tuned it a bit, to reach the min weight and power required.

Now it is time to set it up correctly.

Shaved more than 6 seconds to my first try with the rented Mustang... Just below the bronze time.
Just a bit of work and I'll get it easily (which will get back the credits and more).

Breaking points not spot on yet, and car needs a better setup.

And I hope to reach silver with more training (and maybe better tune when more knowledgeable drivers will share theirs).

Feeling like a snail in a greyhound race in this thread, but I enjoy those Sport Mode TTs I am just beginning to discover.

got to 1:29 in the mustang in session 1 - i basically used praiano's tune - (i max upgraded the car, changed some of the downforce, added front brake balance, and set the max speed to 240 / didnt edit the gears much). tcs 1 without any other assists.

will be interesting to see how it evolves this week, i'm guessing i won't be 25th once there is a common tune! top is in the 1:27s already.

As usual very helpfull to compare feelings with reality.

I want to spend some time from the couch to see what correlation there is between TT rankings and Dailies rankings.

Is it true that the distribution of classes is also found in the TTs? Obviously speaking of statistics the outliers are minor details.

I have almost everything ready at the level of formulas and graphs, but I'm short on data. I have downloaded a few pages of the rankings by hand, but I don't have an automatic tool.

Is it too much if I ask you to pass me an XLS with columns of times and DRs?

I'd happily share it if I had it, but I only scrape name and time. @skidmark69 might be able to help, as I think he scrapes all the data.

What a great time!!, thats fast dude!

This was so frustrating, this morning i took Mushy out and had time for 10 laps before work, until now i didn't feel the BRZ, this morning i was on fire with it, lap 9 i did a 41.082 with 2 huge mistakes?!

All or nothing in lap 10! but stuffed it up quite quickly with 1:30 on the Time trial timer........,
If i had swiched earlier and commited to the BRZ i'm sure i would make it, but thought sticking with the 911 and 200% commit in it would pay off..... :lol: :lol:

But..... started the new time trial at Laguna,
The good news is i was 7th :) this morning ..., bad news was there were only 7 participants......:lol:
I drifted that GT to 4.8 % of the world record on the first official lap :lol:, what a hidious thing to drive,....tuning is key :grumpy::boggled::lol:

I cannot imagine doing the TT right at the end of the timer... The pressure must have been insane, what a way to get the adrenaline rushing (before breakfast!?! :lol:)

That's great figures, cheers for your gold!

I was under the impression that good drivers like you do not have big difference between PB and optimum, but looking at your post it seems that your delta is similar to mine (I'm not speaking of the actual time, just the delta :rolleyes:)

Am I right and this difference is just becuase you were in a rush for the finish of the TT?
Click to expand...
Well, I'm not sure it's useful insight but during the middle of the TT when I hit the wall my delta was roughly my PB and I wasn't improving each lap. At that point, trying to go faster in my head was just braking later and that was losing me a lot of time so also my lap times weren't consistent/lots of crashing/lots of penalties.

What happened yesterday was that I took a long time off, re-watched the WR replays and started again. I noticed that I was oversteering the car causing understeer and braking too late; big time killers in the BRZ. I tried to reset my brain and muscle memory for the car and find new braking points slightly earlier (I think there is a lot of lag in my TV so I have to find my own braking points before ones you see on replays, lap guides etc..).

This tactic gave me the magic moment where you suddenly go faster after 100's of miles of suffering, it's the best feeling!! Suddenly I was in the ghost or within a car length or two until turn 5! The reason I had such a high delta is that came late last night so whilst up to turn 7/8 I was consistently fast, I still hadn't got consistency with the new braking points/steering angles on the last part of the lap. Looking at my PB replay I missed the apex at turn 7, got some scary oversteer after turn 10 and went wide with excitement at turn 12/understeer. So even though the first half of the lap was super quick I never got time to polish the second half of the lap and get that absolute beauty :).

I think the lesson is, we can always go faster and we can always find ways of going faster :odd:

Watching @Mistah_MCA live stream of the new TT... This looks TOUGH. I'm excited! I've got TC1 and CS Strong ready to go :lol:

Quite enjoyable TT despite it being on a track I’m not on the best terms with. Always enjoyable with Gr.3 though and it was cool that several cars could manage some really good times. I had a little bit more than this in me (perhaps a 39.9 or 40.0) but couldn’t quite get it all together and 1’40.128 is my final time.

Click to expand...

Great work! I finally finished in the 1'45.000 group so once again I earned bronze, but I really didn't try hard enough. I wish the cars I use didn't slide so much cause that's where I lose a second or two of time.
 
Famine
It changes with the fastest time. The target is within 3% of the record, so if the record gets faster the gold time does too.
Click to expand...
That's why I thought that the bronze time was around 1'36 and I was surprised to see 1'35.XXX, at the moment I put that on my memory faulting me...

Ok, well bronze will not be that easy in fact 😅

Yep, gold is +3%, silver is +5%, and bronze is +10%. The game does in fact show you this information, and converts them to target times alongside.

yes I've seen those percents but I did not catch that not only it set the time to be in one of the three levels, in comparison to gold time, but that this gold time was also dictated by the world record.

basically used praiano's tune - (i max upgraded the car, changed some of the downforce, added front brake balance, and set the max speed to 240 / didnt edit the gears much). tcs 1 without any other assists.
Click to expand...
Tried to apply Praiano's tune too, did not touch the downforce or brake balance.

I maybe made a mistake by going a step too far in weight reduction, I thought it would do like in the previous TT where it levelled HP and weight to what's required but no. I had to add ballast to get some weight back. At least I can play with it and move it forward or backward depending on how it affects the car.

If you could share your tune, that would be cool :)

forgive the phone photo, properly uploading takes me longer than it should!

Note: I’ve already tinkered with this but haven’t matched my top time. I had the weight a little further back, and the front frequency and front camber higher ( 2.4hz and 2.5 I think) on my top lap, but the rest is the same* (post edit: 6/6 roll bars, 2.4/2.5 freq, 2.5/2.5 damper, i also move the wait around). If someone can figure out the gear ratio calculus on this I think 240 max speed is close to having the gears set perfectly for the turns / curves.

Right, I've given it a go just to see what it's like but I think I will focus on Daily Race C for now and then wait for a decent tune to emerge. Can we widebody the car, I can't see anything that says yes or no!? I did a quick tune and gave it a go, it's a lot of fun! I think this is going to be my favourite time trial yet, I'm really starting to enjoy the road car TT's. Countersteering STRONG I recommend for anyone who might be struggling at the start. Get that on, get your braking and turning points right and focus on getting the car turned in before getting on the power. It seems to have a lot of torque low down so getting it straight before full beans and early upshifts sound like the order of the day!

I might duck in and out but Daily Race C has got my blood pumping (or boiling.. mainly boiling so I'll be there more for a bit). Looking forward to seeing people's tunes because I think making this car less lively will be key to a quick lap

I'm going to have nightmares about this lap time challenge.

This I don't doubt, it was SO entertaining to watch though! :lol::cheers:

Isn't this car quite cheap compared to the nsx? I know I have one gifted as well, but not sure if it was from cafe or ticket.

I think for the nordschleife TT the track was a bigger issue than tuning. Personally I saw little difference in time between tunes, even though they required different driving styles. Since there's no PP limitations there's no weird tunes/pp glitches which differentiate the cars as much in terms of performance.

I think this will be an interesting test to see the effect of tuning at least, cause the track is short enough that it's possible to master in a reasonable amount of time.

YouTubers will have decent tunes out tomorrow anyway
Click to expand...
Yeah, experimenting with tunes on a short track can be fun. I think there will be a few ways to extract a decent time. Nordschleife TT was off putting thanks to the time commitment and regularity of mistakes. An average driver can nail a decent time with enough laps. But you really did need to be an Alien for the Nurb TT!

For people who are just starting/learning to tune a car (Or who just don't want to spend the time on it) these are the 3 easiest and yet biggest changes you can play with to make the car handle how it works for you and all are quick and easy to put back if they have a negative affect. Copying an aliens tune is fine if you can get within a second of them and drive exactly like them, but if you're struggling a little fine tuning to match your driving style could be the difference between Gold and Silver or Bronze.

Focus on the turns you lose time or spend the most time on when tuning though. It's all a compromise. If you find the alien tune is oversteering for you, add some rear downforce or shift the weight to the back. If it's understeering, shift/add to the front. It's not about what is fast for someone else, it's about what is fast for you.
 
1:29.9 - I know that there is half a second in me if I nail an absolutely clean lap. I am not sure what to do with car setup.

Is the concensus of opinion to buy all tuning parts and then use the power restricter to then reduce the bhp, or is that a waste of credit and does it not make any difference how you get your car to the max bhp allowed?

I follow you totally about alien tunes but Praiano's tune makes a basis on which I try to build.

The 3 easiest changes, if I follow you correctly, are :
  • down force
  • break balance
  • ballast position
?

that's a good question, I was wondering nearly that when upgrading my Mustang. I opted for the minimal amount of credits spent regarding power and weight (but mounted everything that was required to use Praiano's tune).

I was messing around earlier, have a decent build but still needs a good tune on it. I went wide body, full weight reduction, full aero and all the adjustable racing parts.
Then added back weight and limited the HP. I will be able to get a silver with it with a few more laps, but I'll need TC1. I put alot of dowforce on it but I think I can dial that back a bit, seems pretty stable mid corner it just wants to break loose on the exit. TC1 helps save it. Again I'm no tuner, was just curious to see what I could do on my own. Going to wait around now for the dust to settle and see what rises to the top.

EDIT: my build wasn't too far off from the video below, but I modified it to match Mistah_MCA and am about one second away from the current gold time.

I have the data saved in a different file format than excel, but here is a link to a text file with time, DR, and time trial ID https://we.tl/t-dVYTqyNcFt

It's 31 MB which was too big to attach directly on here. Guessing you'll have trouble opening the full file in excel since it's 2 million rows, but you can split it by the time trial id to get individual ones.

Not sure how half_sourly gets the data, but I just do it by running a python script and using a package called selenium. If you're interested in this kind of stuff you can get it up and running pretty quickly by just following some tutorials online for web scraping.

Not sure if there's a quicker way to get the data since it is dynamically generated through JavaScript on the website, but if anyone knows of a way please share.

I did have a brief look at the code PD use on their site back when I set the script i use up, but one look was enough to realise it would take more manual effort to decipher that than just get a script to open each page of each time trial and download the data.

Interestingly though if you capture the responses from the website using tools that do that there is more data available than what they display, including which car people use. I just haven't had time to sit down to see if I can automate capturing that data automatically, but might do that in the future if I have nothing to do at work cause I think seeing car specific leaderboards for the gr.3/4 trials would be interesting.
