Re: Setup Thread

Incidentally, I finally broke the 2 minute mark at Sebring last night. Actually managed to do it on 3 separate laps with a mostly full fuel tank and only one of them had an off track.

I'm hoping I can run low 2's for the race but the car gets a bit skittish later in the fuel run particularly in the last turn. It really feels like power on oversteer as the fuel burns off so I'm not entirely sure how to mitigate it?

I'm starting to think that as fuel burns off the car leans more heavily though the turns leading to oversteer. The only way I can think to correct it is to stiffen the suspension a bit but with all the bumps at Sebring it may do more harm than good.

Re: Setup Thread

Nice job. I'd be curious as to what adjustments you'd make to prevent that. Traction control? Not really sure how to balance it out to prevent that sliding late in the race.

I don't have the pace that I know I'm capable of mostly due to the new wheel. But I seem to have enough consistency to race probably mid-pack. I'll look to race probably tomorrow.

There's nothing wrong with your pace at all and I'd wager you're closer to the front than you think.

I only wanted to break into 1:59.xxx just to see if I could on full fuel; I won't be taking it to race (I hope).

Traction Control may not be a bad idea Daunt but I've heard that when it kicks in it costs you speed. My guess is that dialing it up may hurt my speed onto the straight but probably a lot less than a spin would lol.

I'm ready for race right now and have a decent qualify time of 1:20.4xx (full tank) which I'm happy with but I just need a few longer stints to make sure I don't spin like I did last week.

I absolutely love the Macca more and more everytime I belt in but for the life of me I just don't notice sometimes when the car is ready to spin. I got spoiled in the Z4 and the Ruf as they both are very black and white when there ready to go but not the 12C.

I may actually experiment with force feedback settings for this vehicles profile and see if I can exaggerate the feeling of slip.

I've gotten to the point where I can save the car much of the time if I'm aware control loss is imminent but if I have no clue I'm on the razors edge the car gets away from me 9 times out of 10.

Glad you're getting into the swing of the car. It can be a harsh car.

The way I see it, regarding losing time due to dialing up TC late in the race, you're going to be losing speed anyway nursing the throttle on because it can't handle what you were doing before. And the obvious losing time if you spin.

I've not tried it, but now I really would like to do a run and try it out. This has been two weeks in a row now where this has become a serious issue mid to late in my runs.
 
Re: Setup Thread

Just out of curiosity Noel, do these larger files take more than 15 minutes to upload online? If that's the case then it could be a Session ID issue which we'll be stuck with because I can't risk extending the session longer than that (for security purposes).
Compressing it into a .zip did work. I still think the file size is the issue because it got quite a bit smaller now (not a bad thing to do anyway). The cutoff seems to be at around 8 MB.

The upload time is probably not a problem. The whole file uploads in about 5-10 seconds.
 
Re: Setup Thread

I've done three races now and I'd say the tires losing grip is quite normal. It seems to be most noticeable past the half-way point of the race.

By then I get understeer in the slow corners, as well as T17 and I need to be more careful on the exit of T17 as well. I also notice when my line is not quite accurate in T11 it has a tendency to break loose at the rear. That is when the tires are worn a little.

Traction control should help at least somewhat in making the car safer with tire wear. They say indeed that you can be faster when it's turned off but the difference should be small. I haven't noticed any. Also, to get that little speed increase you need to be accurate with the throttle otherwise you're just spinning speed away or you're too afraid to give enough power. I might be doing one of those things sometimes but I just like to drive with TC off.

My second race was crazy, top split of 3. Let me show you how I got 12x halfway through lap 1:
[video=youtube;_Iw5ZYbDX0o]https://www.youtube.com/watch?v=_Iw5ZYbDX0o[/video]

For the first one I can't really blame the guy that rear-ended me. I also tapped the car in front of me. The problem is, you hear "green" and everyone charges ahead. Everyone, except the leader...
This wouldn't normally be a problem, but the 2nd position jumped the start. I think he also got a black flag for it because he stopped at the hairpin and then quit :)

The second 4x was with the green car. It's a good example of what we had a discussion about Duke. If you're almost next to someone and that someone moves over in or right before the braking zone there is not much you can do. To be fair, I did the same thing to the guy behind me on the corner before. If that guy had hit me I would take responsibility for that but he could brake in time (nerf BMW plz).

Then right after I hit the green car he decides to cross into my line in the corner for some reason which turns his car around (after which about 3 more cars crash into him).

The last incident was with the yellow car. It looked like he got scared and assumed I was gonna dive bomb him. That made him slide a bit and drift into my line.

I agree that some of my moves were a little aggressive but I don't think any of them were wrong. I was clearly behind slower cars as I gridded 3rd so I didn't see a reason to stick behind them, losing valuable time. I got lucky in the end because I still managed to climb back to 4th. It wasn't my fastest pace either because of all the damage.

Re: Setup Thread

What a mess! I'd say the 1&3 were definitely not your fault. 2nd was just a racing incident. You made contact and he figured (I think) you backed off and then decided to come down.

Re: Setup Thread

OMG what a nightmare, none of that looked like a top split race to me lol.

You're IR and SR must have taken a beating in that race lol.

SR -0.35 which put me to just over 2.00 :p.
I gained iRating though, +48, because I finished 4th in the #4 car. After the first few turns I was below position 20 but a lot of people in front of me crashed in that race.
 
Re: Setup Thread

View attachment Suzuka_custom_QUAL.sto

Car: McLaren MP4-12C

Track: Suzuka
Type: Qualifying
Season: 2014 - S04
Properties: Wing is at 4 to make all the heavy turning doable. Will hurt on the straights but I think they are a less important part of the track. There is 20 L, which can be decreased somewhat for a fast qualifying lap. Interestingly, I feel like I have more grip on lap 1 than on lap 0 through the esses. Haven't bothered changing the shocks, they seem to be working for me here. Turning while on the brakes can be dangerous, mainly at T1 and T13 but that should be expected from a McLaren. Otherwise, it should be pretty stable.
I might have lied a bit that I do T7 full throttle. I try to find the right turn in point at which I (try) to go full throttle. If you get the turn in right, it's possible to go full throttle from there.

Here is a low 1:58. I spent quite a lot of laps trying to get into the 1:57's but the first and last sector are hard to do consistently fast. So is the double (edit) right (with the curbs). I lost .20 sec from my previous best time there.

Re: Setup Thread

I turned some laps last night but found it impossible to get through the track consistently.

I was taking late apexes on the esses focusing on keeping toward the middle to middle right of the road to get a good run up the hill straight'ish. That one section is what got me into the 20's but there is a ton of time left on the track, I just don't know how to get it?

I know I'm losing time in the double right and probably some time coming out of the hairpin. Also doing the double turn just before the run up the hill is killing me as well as I just can't find the proper line or pace to get through that section.

With a lot more practice I think I could hit high 19's but there would be no way I could take that to a race. Race pace for me this week would likely be in the high 20's, possibly low 21's. :eek:

Am I missing something? high 20s? What track were you driving??

Re: Setup Thread

I meant 2:00 and 2:01.
I figured but wasn't sure if you were just that slow. I was about to celebrate at finally being better than you duke.

We should get in the habit of posting these with our setups:

suzukaopts.jpg

This was after some qualify setup practice. I went into a Q session and murdered my SR. The kink (T14) is disastrous with qualify fuel. I can take it with a slight lift in full fuel but with no weight in the back (Now I have to assume that's where the fuel is) taking it like I did is impossible, the rear end spins out every single time.

You can really see how inconsistent and terrible I am with that though. Over a second difference between my OPT and BEST. And I worked hard at that best lap. Probably could get it below 2:00 but would be too much wasted effort. Need more consistency. And this will never be my race pace.

Re: Setup Thread

I did some research into the fuel tank with Akkip last weekend and we found some pictures that clearly show the fuel tank right behind the seats and in front of the engine.

That means the weight is lightened reasonably consistently over the course of a longer run in both front and rear making the ride height probably a little higher and the suspension slightly less compressed/pre-loaded.

It actually explains everything really and how it affects your lap-times depends primarily on your driving style. I know both Daunt and Noodle were having oversteer issues whereas I was having more pronounced understeer and power on oversteer only.

Incidentally Daunt, was that time posted with Qualify fuel load and if so, how much?

Re: Setup Thread

Very interesting about the fuel tank. That is an ideal spot to put it I'd imagine. Those McLaren engineers... geniuses.

Yes. Car is much easier in the esses. As I said the only time I have major issues with lower fuel load was in the kink T13. You can see that it is 4 tenths off my opt. My race pace will be in the 2:01s I'm sure. If that. I will definitely be on tonight practicing, probably moving into full fuel run practice.

Re: Setup Thread

I'll try to be there but I'm more annoying than normal because I'm clearing my throat constantly. If it becomes bothersome then tell me and I'll leave.

This cold/flu whatever it is won't decide on whether it wants me sick or healthy it seems.

Re: Setup Thread

I've done almost zero close proximity practice here, and no passing. And here at Suzuka I feel like it is very difficult and very important. So if you're on that would be sweet. If not, that's alright, I need practice anyway. If you're annoying I'll just run you off the track. Probably not on purpose with my driving.

Re: Setup Thread

Alright, I'll idle in Teamspeak tonight but I'll probably be sleeping it off a bit so just yell at me a few times and I'll get there.

I can't say how long I'll be around though. Last night I managed about an hour or so and that was plenty :icon_confused:
 
Re: Setup Thread

Apexes are very important on this track. The corners from T3 (first left) up to and including the long left up the hill are all strung together. If you deviate from the line there you will pay for it pretty much the rest of that section.

To me, it feels like I have to push the car past a comfortable point. But if you push too hard you will have mini slides during or right after turn-in which slow you down.

Daunt, don't you mean the kink at T14? The sooner you turn in there, the earlier you can go on the throttle again. I try to stay away from the green stuff right next to the rumble strip on the outside because that's almost guaranteed to make you spin horribly.

In the McLaren iRacing forums Antti has posted a setup and replay too. He somehow managed a 1:57.2. I'll probably try his setup too to see if it makes a beneficial difference.

Next week is the second race of Masters of Endurance, at Suzuka. The weather seems to be slightly slower than the official series weather. They're speculating a qualifying cut somewhere between 1:58.5 - 1:58.8. That means that any team slower than that wouldn't make the top 60... crazy.
