UKGPL Season 22 (2011-2012) Porsche - Nürburgring (Nordschleife) - Feb 3

[b_1_rd]

Well, I had a poor start coming to a stop avoiding sky's spinning car and then had a front row seat while at least one other car went sailing in to him :/ and from there on it just got worse.

Dispite trying lots of different combinations of setups I still get a random issue under braking. I'm not standing on the brakes, indeed on most occasions I'm using less than 1/2 pressure and still get front lock ups. I have no more time to mess around with it, tweaking for hours just to end up in a hedge after 5 minutes so I will no longer race with GTs.

Anyway, well done to any that finished.

[Rainier]

I had a nice battle during the 6 first laps with JonnyO and Fulvio and a the start of the 7 laps I was comfortably 5th without any hope for the 4th position (Fulvio) and with an advantage of over 20 seconds on the 6th (JonnyO), but...

...but I started to race in the brainless mod and try to beat my PB : I spun and the race ended for me against a tree !
Congratulations to the podium, all finishers and especially to Jonny0 and Pierre D
Sorry for my team, for the next race I will try to buy me a brand new brain    

[Pierre D]

It was clear from the beginning that everybody was faster than I no matter how I spell it. "11%" looks better than "a full minute" but it is still the difference between my best lap and Tristan's.
You know what ? It's like custom bikes vs cafe racers, if you like it, why are you trying so much to put an end to the experience as soon as possible ? 
Rules of the Ring for me: stay out the way, be polite, don't allow your mind to start roaming.  Last night was a great one for me. I was lucky at the start and then lap two 9:31.93, lap three 9:31.04, lap four 9:30.37, lap five 9:30.11.  The mind roaming part hit me at the 6th lap and I made several mistakes. I talked to myself, we both agreed we had to be more careful and we managed to finish before sundown.

Congratulations to Tristan and Maxime.  LOL Racing has done it again !

hi Steve ,



Steve I got the same trouble yesterday .
But must say I never had this before so constantly while racing Porsche online .
During qualy my first 3 attempts ended very early coz of this .
During first race lap I lost control heavily 2 times and final at L2 . Results in car falls headlong .
Strangely this syndrome to me had been present very very rarely during practise offline ( against 6 AI ) maybe off about one time out of  12 laps .

I am unable to make sense out of it . Didn’t had a single issue last race at Sepang for example

Even this thread  didnt spent any light on whats the reason realy is .
`Locked brake issue on Gtmod  `
http://srmz.net/index.php?showtopic=6986

But one thing for sure ; it couldn’t been cured by setup work afaik.

Only thing I noticed , that it seems to be extreme worse the moment your are close behind another car under breaking . To me it looks like draft effect measurement and GPLs slow speed grip issue as an addition do force the locked brake effect .

But still , as this isn’t constantly happened , I havnt a clue .

Something to do with specific  tracks ? or server settings , or client settings , or bandwith quality in general  ?
As it seems  my fps never drops under 35fps online ( using gplshift device , fps shown at right upper corner  ) I guess it had nothing to do with fps drops . But I am not sure , especially this time many drivers report they got pure fps …

Apart from said all above ,  I hope you will change ya mind and keep up with us ,  enjoying this nice Porsche .

I think you missed the point Nicky. I wasn't moaning (well, just a bit!). I am physically not around at 9pm to start the server so I start it at 8:30. I only get back around 9.20 so I join with ten minutes to go but I have to start the servers earlier so that the race can start on time.

[BadBlood]

After getting going (probably last)

No you weren't

I saw you and Geoff having a tangle and decided it was easier to let you both go. I was pleased that I kept you in sight for a lap.

Try to avoid this behaviour raising the front of the car, softening the springs and having a brake bias more to the back so that the braking force to the front wheels are extremely soft. In any case remember that the friction the tire can offers (grip) is a costant value that is spread in two parts during corners permitting the car to turn and at the same time to brake. When that costand vale will be overtaken (because of turning too fast or because of braking too hard or both) then the tire will slide and when it happens during corners the car will go straight ahead. This happens to me several times so I've tried to avoid this raising the front of the car, softening the springs and shifting the brake bias to the back. And this is not enough sometimes tho so the only thing that remains to try is...to brake gently and before.
If anyone knows much more it would be nice to explains own experience to solve this problem.
Thanks.

Also Tom Guerout had the same problem at Solitude (last season) after the long straight and he went off road as well.

I believe these unwanted lockups, are caused by the car's handbrake.  It may sound odd, but that's an in game feature they are all fitted with, without most drivers realizing it. 

When you arrive at a track with a slope, such as Spa, your car should realistically roll down the hill.  It must've been decided, this would be inconvenient, so a pseudo-handbrake was added.  As soon as the car starts moving, the effect is released.  But for some strange reason, the GT's are triggering the handbrake, while the cars are still moving.

GPL physics are complicated - that's why the Sim is so good, but it also means any strange behavior is difficult to fix.  For us, the fastest lockup release seems to be, to add speed, as if you were on the startline.  By doing this, brake lockup on corner exits, should no longer be a big problem.   

[JonnyO]

  Finishing 4th was greater than expected!

  Much of the race was fantastic in a dispute with Rainier, but then I was tired and could not keep up.

  I'm sorry for Rainier, he left the last round.

  Congrats to the podium!!!!

In a track like Spa, my Porsche rolls alone down the pitt stalls if I don't press the brake so I don't know what do you mean with hand brake !

[maddog]

You make an interesting point Sergio.  All the F1 cars when stopped, will stay stopped. But  I just tried a GT at Spa, and it rolls when it arrives, so the automatic handbrake is faulty.  I think it switches on at the wrong time.

[clouds]

I don't know how the handbrake is implemented in GT mod but if it is, in the reality the handbrake applies only to the back wheels not to all the 4 wheels, so it seems strange to me how the front wheels are so involved in this kind of problems, anyway the problem is real for sure.

[s2173]

I still have the problem too... lately I got used to it, with softer springs and bump larger than rebound it seems to be minimised... also at crucial spots, where I know they can lock, I slam the brakes and release them very fast several times in row, making the car feel like a rocking chair. Maybe some setup with more weight at front? Anyway, I still make my setups mostly randomly, and im still slower with gt's than with any open wheel car....

The F1 67's do roll down at Spa

Excuse me a mo'  . . . "Grumble, grumble!"  Ok, that's better!  Any other sensible ideas, on the cause of our GT's, rotationally challenged inclination, please post here.
