Title: Season 19 - World Endurance Championship on practice server
Post by: Wally on September 26, 2017, 11:19:37 PM
The XGN Tue Practice server currently has the season 19 cars on it, at Mugello. This is just to try the cars and for you to experiment with the LMP1 MGU-K settings (wassat, I hear you ask), rather than to have a race night at Mugello. We'll have a couple of fun or practice races in the next two coming Tuesdays (to be decided), until season 19 proper starts.

But in the meantime, jump on the practice server and try some cars, set some times.

Only the Porsche LMP1 has 75% restrictor to bring it closer to the Toyota and Audi LMP1 cars in lap time. All other cars have no restriction.

It's also a good opportunity to experiment with the MGU-K (Motor Generator Unit-Kinetic) in the LMP1 cars. You will need to map a KERS button so that you can manually activate it. Also get familiar with how your HUD of choice displays how much KERS you have left to activate.

Each LMP1 car has 6 MGU-K modes, which give different profiles for how the energy is harvested from braking and applied automatically under power, which are explained by AC's Aris as:

Quote
The Low setting uses less battery, especially on higher speeds/gears
The High setting uses more battery in higher speeds/gears

The Preserve from Aggressive setting, changes how torque is transferred to the front wheels, depending on their slip and thus using more or less battery and heating/wearing more or less the front tyres. Obviously the aggressive setting will give faster lap times but put the front tyres in more stress as well as consume more battery/energy per lap.

Keep in mind that LMP1 drivers use as low a setting as possible and manually boost the ERS with the button in order to overtake slower cars or defend their position.

Some people say it's best to use the "Charging" mode, which doesn't automatically deploy the KERS but leaves its deployment entirely up to you via the manual button activation, so you can choose exactly when to use it. The amount you can deploy resets at the start of each lap (but not how much you have harvested).

In addition to this, you can also cycle through the MGU-K modes on-track with Ctrl-2.

For those of us who don't own the ready to race dlc you can't actually join the server :(

Just a heads up...

I'm not sure what car comes with what DLC any more. There's too many cars and DLCs for me to keep track of. The people who have the DLC want to use it, so I generally just assume everybody has the DLCs.

All fixed. Turned out I had to update the OSRW version of the track. Note that this was necessary (at least for me?) even though the practice server is not using OSRW version.

A point on the KERS.

As Wally pointed out, you can harvest as much energy as you want/can, but the deployment is limited.
And it's limited by energy deployed, not time.
So if you use a low or preserve setting, it deploys at a lower power level and gives you more time on boost.
But when you use the button it deploys at the maximum allowed, so less time, but more instantaneous power.

AND, to make matters worse, each car has different characteristics.
For example;
The Toyota (on low preserve) uses almost all it's allocation automatically, leaving just a small amount of time for manual boost.
Whereas the Porsche (on low preserve again) uses much less automatically, leaving much more for manual usage.
And weirdly the Audi still boosts in charging mode, which seems counter-intuitive. ???

So my point is (I think), if your smart you choose a GT3! :o

It is complicated, it's true. I think the best option so far in each of the 3 cars is to leave the MGU-K in Charging mode and deploy the KERS manually.

But Seanus and I just had a 6 lap race at Mugello, and the cat and mouse deployment of KERS at different times to try to overtake or defend, while also trying to preserve energy for later in the lap, was a really interesting element of the racing. I saw that Seanus was using his KERS to catch up, but rather than panic and use my own KERS, I knew he'd use it up while I still had some in reserve for later in the lap to pull away again. It will also take some situational awareness of how clear the track is in front of you to make use of the boost, and also to think if you're going to need to save it to pass some upcoming GT3's ahead of you without getting held up. It will be fascinating.

Fair call mate. I thought it would have been ok to run the GT3 cars without having the content.

Looking at Gratulin's response i'll try and update the track now and then retry tomorrow night. That aside I see a good excuse for some more DLC haha

The only thing discouraging me from using charging only is the boost is most effective in the lower gears.
I'm usually too busy correcting power oversteer exiting a corner to push a button! :o

In the Audi I had to stay in charging mode as it was the only mode that left any boost for the main straight.
Even the Toyota could only use low preserve, and I'm not quite sure when you would use any other mode.
Hotlap mode in both cars saw me run out of boost after half a lap or so, which I'm sure is not the quickest way around the track.

Mugello is a bad track for regeneration in general.
There's really only the one big stop at the end of the straight, the rest are smaller braking zones and much more flowing.
The Audi is even more handicapped in this respect as it has no regeneration on the front axle, which is more efficient.

Hey Wally,

I fear there is a bit of a problem with the LMP1s. I wanted to try the audi. I worked on it for a few laps and tried to learn the MGU-K and then I went for a few all-out laps on softs. I managed a 1:34.6.

Then I took the Porsche with 75% restrictor and on one single lap, all default, I did a 1:33.3. That sounds like a 2 to 3 seconds per lap advantage...

EDIT: I should clarify that my few laps do not mean so much. Just an alarm bell. Nothing more. Will test more, of course.

Personally, I was only 0.2 secs faster in the Porsche than the Audi. Different drivers will extract more or less out of each car. Seanus and Mael are very fast in the Toyota. I'll have to keep an eye on it and see if the Porsche still ends up too fast on the practice server times, and maybe go to 80% restrictor.

Maybe you're right. I seem to have a disproportionate gap between the cars compared to the others. Maybe the audi and me really don't like each other.... I guess I'll take the porsche now. I also like how it drives more.

Only joking, I have no idea what I'll drive, I can't test till Thursday when I get home. I was thinking of racing lmp1 only because I've never really driven them yet and since since signing up with you guys that's all I've been doing, which I like btw. I've been out of my comfort zone and trying new stuff, it's cool. While away all can do is go by comments here from you guys and watch YouTube videos on the different cars.  8)

All three of the LMP1s feel different to drive in some way. It might be just as important to choose a car that you feel comfortable with. You'll be driving it for an hour, after all.

We've never raced the LMP1s in a season before. I'm mostly looking forward to KERS strategy.

Ok... tech support please...

I've purchased and downloaded the ready to race pack. Rebooted A/C. "Server contains unavailable content".

Recall seeing there was the OSR pit box comment somewhere a while back. Go and download the OSR pack from the forum link. Reboot A/C. "Server contains unavailable content".

Any thoughts as to what on earth i'm missing here? This is driving me nuts.


Update:
Ok... just realised the issue. It's the porsche causing the issue as its another DLC again. Looks like I might be out for this season. Just spent $120 on a new game, bit hard to justify to the minister of finance another $25-30 for "another game" right now. Will see how I go.

a quick test for me offline, i drove the porsche on charging mode to try and simulate the 75% restrictor and i found the times it did was the same as the audi around the nurburgring but 10kmh slower on straights, but the toyota was way quicker to the tune of 1.5 secs but again 10kmh slower down straight to the audi so a restrictor wouldnt work i think the toyota may need ballast since it makes all its time in the turns.

Mmmmh... yes, that sounds more or less like the impression we got from the practice race. I guess it's tricky. I am not in favour of large ballasts, but maybe we could give a small one and let the tracks decide which car is faster.

Post by: Wally on October 08, 2017, 10:49:54 PM
I won't be changing any ballast or restrictors now so close to season start. Some tracks are tighter, some are more flowing. There are many variables to balance, including driver skill, and don't forget it's also an hour race.
