C'mon @suomi1 ! Almost there mate!
Race engineer voice over radio: Head down. Let's nail this!

 

[Voodoovaj]

I think I have found another alternative to get more difficulty out of the races.
(Disclaimer, not to used to avoid the post pit stop rubber band IF you happen to get to first place. I haven't tested that yet.)

I found this after looking at a field of cars following a rabbit that was about 100pp better than the field. The field went after the rabbit for a while, but as the gap grew, they seems to slow down and rubber band back to me, so there was a line of like 10 cars just waiting nose to tail for me to pass them. So, I started thinking that I'll make the rabbit just fast enough.

(Recap) A few months ago, I set up a few races with "Rivals". Sega used a "Rival" for Ayrton Senna's Super Monaco Grand Prix. So, you didn't have to win the race, you just had to beat your rival. This is what lead me to rely more of PP for race balance than power/weight or BoP. So, this came to mind again.

I went through a few races (Group C and 90's LMGT) and I gave a few cars an extra 5-10pp (It seems 3-5 does the trick). 5-10 PP more than what is necessary for balance, so you intentionally imbalance these cars (just a bit). The cars should be about about 0.5 to 1 second faster than they would normally be (which is usually what 5-10pp gets you).

I take this handful of cars and I sprinkle them in the pack. Put one in the top 3, another one or two in the top 10, and maybe another just outside the top 10. The result seems to be that it pulls the field toward them, making the racing more competitive. Not just the boosted cars, but all the cars. They all start running at 100%.

Also, I turned on heavy damage. Definitely the way to go. It mixes up the field.

So far, I have only done 5 lap races, but try this and see what you think.


EDIT - I did a 15 lap race with 1 stop. All Abarth 500's tuned to 600pp except for a few at 610pp. I started last and finished 10th. I got up as high as 6th but I was passed on track by the regular cars on fresher tires. Seems like people racing. No overt rubber banding. This looks promising.

This is it, 24 Hours on GT7 at last !

Spoiler: RESULTS + some infos

Few (not new) things to say here, as Pody always find a way to mess with something.

First, every car that cross the line when the 24 Hours are elapsed have their race considered as finished, even if the leader is still racing. Normally the leader is the one who finishes the race and receives the checkered flag first, then comes the turn of the following cars on track so you have the real gaps.

Second, the AI is bad at calculating fuel needed for the last stint so it often pits for a last lap, even sometimes for a fictional lap as the checkered flag is already being waved.

Third, if a car enters the pit lane as the checkered flad is already being waved, or if a car is still into the pit lane when the checkered flag is waved, they are all immobilized in the stands and their race is considered as finished.

All of the three happened here, and the final ranking is all over the place which is sad after a freaking 24 Hours race... Take notes before the end of a long race because the replay can be recorded but won't go all the way through (about 17 hours of racing recorded for me, 3.9Go looks like the maximum size possible).

Here are the real final results (more or less), before everything gone wrong :
1 - Porsche #17
2 - Toyota #2 (+/- 1s)
3 - Porsche #18 (+/- 2s)
4 - Toyota #1 (+/- 10s)
5 - Audi #8 (+/- 10s)
6 - Porsche #19 (+/- 20s)
7 - Audi #9 (+/- 20s)
8 - Audi #7 (+/- 30s)

Quite different eh ? The rest is correct except for me, I should be 47 laps behind the leader too. I ended 1 minute and 17 seconds in front of the #97 Aston Martin, we were all in the same lap. I lapped the #51 Ferrari at some point but I needed to pit.

Spoiler: Few pics at dawn

No race report of course, That would take more time than the race itself. lol
Just to say I will forever remember an epic battle with both Aston Martin and Porsche in the middle of the night during at least 4 stints. Breaking free from the pack was no easy task.

I'll quickly modify the LMGTE BoP as soon as I have time. It's not bad considering the final result, but there's room for improvement. The LMP1 one, on the other hand, is working brilliantly.

I expected the pay to be higher IMO

Second, the AI is bad at calculating fuel needed for the last stint so it often pits for a last lap, even sometimes for a fictional lap as the checkered flag is already being waved.

This is why in my 1 hour races I went back to 1x fuel consumption. Because they were doing weird things like pitting with 5 laps to go for the first time, and then pitting again with 1 or 2 laps to go for more fuel.

 

[CodeRedR51]

In the process of doing a complete re-branding of my GT4 series. Changing most of the liveries, switching to Dunlop, and splitting the field into Pro and Am classes. Did a test race tonight at Spa since I haven't raced there since before Spec III and not much has changed. Still take the wrong line through Raidillon and slow through the kink before the straight. Also slow through Les Combes and Malmedy. Rest of the lap is pretty good. I did notice they carry more speed through Blanchimont than before but that's probably due to something I did.

Either way, this happened during the race and it's the first time I think I have seen an AI car spin another out.

 

[suomi1]

For me it ended up x1 fuel consumption was far more difficult to balance than x2. I run really long races most of the time so that matters a lot in my situation.

Not to mention that LMP1, just to take them as an exemple, would be able to set 26 laps stints. Which sounds, really weird to me ears...

I get the idea though. All in all it all depends on what the goal is, what cars are used and how you customize your race.

 

[Voodoovaj]

I put some engine swap into my F3500's and I adjusted the power levels to be closer to real output levels for the customer cars. I have a Nigel Mansell Williams Renault with a full power Renault v10 out front. Senna V12 McLaren second and Prost's v12 Ferrari 3rd, and so on.

I entered this race with a v8 Benetton, with a +/-90hp disadvantage. You can see the difficulty got to 7/9. I got up to 5th place in 5 laps and I think that was about as far as I would go. I stretch the race out to 10 laps and I got to 9th from 10th.

Waiting for a few replays download. Have some nice spots to spectate at CGV and YM.

 

[CodeRedR51]

Did two, 10 lap test races tonight at Road Atlanta with the GT4 series. For both, I started in P11. Before the races I decreased the AI downforce to 150/230.

First race, I went nowhere. Actually got passed by a Supra on lap 7, then an NSX took me out of lap 8 trying to pass me in T1. I was very slow down the long straight. Super tense race trying to hold position. Starting grid interval was 30 meters.

Race 2, adjusted my ECU +2 clicks and decreased the start interval to 25 meters. Had some good battles and made up 5 spots. Some of the cars in front of me in race 1 that were holding their own, went backwards in race 2. 🤔

Going to -1 my ECU for the next race and increase the AI downforce a bit since some of them appeared to be struggling.

Try what I did. Get rid of your rabbit and replace it with a car that's about 5-10 pp better than the rest. Add 2-3 of those cars. It seems to make everyone faster. I'm not sure why yet. I think it's something in the race code that pushes the AI to maintain a smaller gap, unless the lead car takes off, at which point they break off the chase.

I'm getting GREAT results.

Can we change car settings with BoP on? I know we shouldn't suppose to be able to change, but sometimes there are ways 😅

The PP spread in the field is like 617-628. Plenty of cars that could be up front if they want to be.

A quick question after a thought I had playing some Nordscheife races from the Power Pack earlier today...

Have any of you Custom Race creators had a pop at recreating the Power Pack races, maybe by attempting to decrypt the individual specs for the cars from the info that we can see?

I wish they let us buy all the tuned cars. I never thought the Civics could be so much fun to drive.

 

[GTvsForza]

I don't think there's a way to look at the telemetry of the AI cars.

doubt it - for now, at least. seems like tuning sheet is hidden so one would have to spend a lot of time trial/error tuning to create the same feel/performance as experienced in the powerpack. Color me interested to learn about this if someone is willing to invest the effort!

 

[CodeRedR51]

The PP spread in the field is like 617-628. Plenty of cars that could be up front if they want to be.

Update: Made some changes and ran another 10 lapper. Increased the power on the BMW's and the McLarens, then put the downforce on all of the cars to the middle mark. (175/275 I think) Started P11 again and finished.....P9. Only 2 spots gained in 10 laps. I can still see that I am a bit faster than the AI cars in the corners and still a little slow down the straights, so going to do a small downforce reduction on my car and give it another go...

Edit: Tweaking things here and there, last couple races were a P11 to P8 affair. Last one I actually lost a couple spots and had to get them back. Saved and shared the replay if anyone is interested:

Edit 2: Made a couple small changes and did a full 55 minute race. Changed the setup on one of the Supras because it's fast but a bit tail happy. Suspension tune must have been junk because that car went backwards quickly. 😄 My race was probably the hardest fight I have ever had doing this stuff. I did end up winning, but with 3x tire wear 8 cars made a second pit stop, including the top 2 cars. SO, we're going to put the original tune back on the Supra and change the tire wear to 2x, and go again. If that goes well, I'll do a full race at Suzuka to see how that goes since that's probably Sophy's best track. And if that goes well, I will start another 6 race season and live stream the races. 💪

What is your PP? Just try it. Make the first two cars 635pp. It's easy enough to go back

Top 2 cars in my race last night were 626 and 622. Im at 618. I am 99% satisfied with where I have it now.

If someone have old screen shots of the Daily Races or World Tours with the Route X road cars, that’s a start to at least get power/weight specs.

If I were to do it, I wouldn't be looking for exact specs. Near enough would do, just using the cars in question order to establish an interesting tuning grid.

 

[pritchyTim]

sounds clever (and correct)! though not sure I appreciate what you mean by “Route X road cars” and how old versions of those relate to the Powerpack tunes.

@benjoi84 if you can get a screenshot of that qualifying table (cars and laptimes), you’re probably in shape to recreate. Depending on what you are looking for, go from there. I’d personally try to create a balanced grid - tune my car to run a similar laptime as the screenshot, tune the rest of the cars to my car’s PP (+/- pending trial and error patience), applying the usual Custom Race techniques. Were you to prefer the spread of the powerpack, naturally you could downtune some backmarkers and soup up some Miyazonos. Where we’ll obviously fail to compare is in whatever tire diversity is programmed into the powerpack. Share your results if you’re up for it!

 

[benjoi84]

@pritchyTim I might do it, game time allowing.

There's more chance of that than 6 hours of Suzuka or 24h of Le Mans, anyway.

 

[CodeRedR51]

More testing, more tweaking. Edit: Ran a few more 12 lap races after posting this, first race I picked up 2 spots. Second race I passed 2 cars but one of them got me back before the finish. For the last race I took those settings and the only change was that I put slipstream on "real". Finished 3rd. Still a fun race, but way easier to pass. And the field shuffled a bit more too. But I prefer the challenge of no slipstream so I will turn that off again. Now to try these settings at Suzuka and we should be good to go.

Here's the current BOP:

Good battle here with the Ferrari with a smooth pass.



And don't be like me, pay attention to the blinky lights ahead so you don't almost slam into cars going on pit road.

I did a 90 minute race at Monza yesterday with my WEC grid (2 Gr1 Toyota, 18 Gr3, BoP on, Sophy on Professional, Weak Boost, Real Slipstream).

Key takeaways:
1. All AI cars maintained their pace during the entire race.
2. There were some pairings and the end results are mostly related to fuel consumption. The chevies are always last even if the start mid pack.
3. I need to check the replay in more detail, but one of the Mustangs and one of the Aston Martin pitted way early than their sister cars. This is odd. The Aston was leading the Gr3 class so maybe it used more fuel. I also need to check if they double stint the tyres or if they always changed them.
4. I started p7, was p9 at some point, but managed to climb to p4 before the first pitstops and saved fuel in the 2nd and 3rd stints (even used map2) and was able to keep the same pace as AI finishing p1 for the class. The Aston Marting did overtake me in the final laps because I was saving fuel, but had to pit again.
5. My best lap was mid 52, and the best AI did high 53. They are a bit slow.
6. The 2nd Gr1 car, managed to rear end me in T1 giving me damage (set on High) in with 5 laps to go. I still managed to keep my delta to p2 even with damage. The Gr1 car pitted to fix the car.

Monza is a slow track for Sophy. They slow down way too much before t1 and especially before the chicanes.

T1 didn't seem too bad. The 2nd chicane and the SS were where they seemed to be slower.

But I agree, it's not a track where Sophy seems to be fast.

Hi,

I am trying to come up with my own Multi-class race with 13 Gr.3 cars but I am out of ideas with the remaining 7 cars as I don't want to use Gr.1 or Gr.4 cars.

Are there any good suggestions? I dont mind making mods to all cars so they can be equally balanced.

Thanks

I used the Peugeot and Toyota GT-one as Daytona Prototypes. If you have multiples of those they could work as a higher class.

Well one hour at 24x Daytona 24H. By the GT-One’s clock the race started at 15:58 and end of the hour it crossed the line at 15:52. I crossed the line at exactly one hour and couldn’t complete the lap. P3 was just behind about to lap me.

Tough race. No bands of rubber to help me move up. Parked the 787B swaps and used the turbo set ups. The AI still not at full throttle helped their fuel economy(fuel /tyres at 5x/10x). All though I pit same amount of laps(5) for fuel, I was at 1% when AI were at 8-10%.

AI RX-8s just can’t hang on long straights. Other than that, feels good to struggle to keep pace.
