UKGPL Season 44 (Spring 2024) 1967 F1 (Privateers) - Hockenheim - Feb 25

I don't know how people use 49 - 52 % brake bias and dont lose their cars. Is it the braking + accelerator technic?

Lasse Albrecht from asteroid B612 almost never lets off of the accelerator. His setup for this track has ramp angles of 30/85 and a FBB of 49%. This, obviously, is not for everyone.

With the default setup i found 48% brake and i have lost the car!Again remain unknow why,entering the race,both the setup swop on default.

I bought GPL in November of 1993

You mean 1998 ?


About brake, I used 51% during the qually but I didn't find it easy so I changed it to 52% and it was almost perfect for me with the Honda.

Racers excuse number 254: I run at 2 locations. I have been in Southport for most of last week, with my old PC and a G29
The G29 brake pedal has some rubbber thing when you press hard, so is easy to brake gently, works perfectly for 55GP mod
I had done a lot of practice there. I could do 55 secs fairly repeatably in the Honda, and occasional low 52 in the Eagle

I need to be here at my place near Rochdale this week, and there's a Thrustmaster Txxx here, which I am always slower with
for some reason. I copied all my setups for Hock, and went on line, and as Pepe said I was horribly slow. mostly because
this wheel is bigger, and the brake pedal moves too easily (I have a bracket with a rubber block, but it's not yet fitted)
and I was losing it all over the place. It's surprising how much difference one wheel can be over another  

I spent most of qual changing the setup so I could drive at any sort of pace. Was sort of ok for the race.
Spun off the line like an idiot... fortunately no contact. then managed some decent enough laps and caught up
when Pepe and Paul had an incident I passed and then followed a series of 1st Pepe then Paul trying to outdrag
the Honda down the straights   More than once we were side by side as the Ferri got better acceleration out of
the Nord curve, but HondaPower clawed it back. I managed to throw away 2 places on the penultimate lap
by spinning in the stadium, letting them both past  

My brake settings are usually 55-62 depending on the car. If I go lower than that I lose it into corners
I tend to brake quite late, some would say it's "trailbraking" but whatever it is I can't run low 50s
and 40 something is beyond my capabilities.

A good race, even if I was still a bit off the pace

Brabham blew a valve on lap 3, and I feel I was running so well . . . . . seems if anything can go wrong this season, it will!   lol

I agree with Axel.  Using a brake balance of around 50% is an acquired skill and is not always the fastest solution for ALL individuals. It is said that the very quickest guys use a 30/85 diff with 49% brake balance and the theory is that:-

Having the BB set to the rear allows the front wheels to continue rolling and therefore allows a "turn in" to the corner because a locked front wheel only goes straight on.

Careful pressure control on the brake pedal prevents the rears locking ( and keeping 20% throttle depressed also helps ). This is where it gets clever and complicated.

A 30 value on the power side of the diff effectively locks the two rear wheels together, and if 20% of gas is still engaged, then it is the power side of the diff that is operational. One might expect this to result in the car refusing to turn and ploughing straight into the scenery. BUT, careful and practised dancing on the pedals can effect miracles.
a) a momentary lift off of the gas pedal will engage the 85 coast side of the diff which will instantly cause the car to turn, and once we have it pointing towards the apex we get back on the gas ( locking the two rear tyres together again and giving a bigger combined contact patch to deliver acceleration out of the corner in a classic 4 wheel drift.
b) allowing the rear wheels to lock will almost certainly cause the rear end to step out and point the car towards the apex. This requires deft and accurate pedal dancing or the result is either a spin or molten tyres, or both.
c) a combination of both.

The skill factor is balancing all of the forces consistently ( this is where I go wrong 80% of the time ). The aliens amongst us are doing this instinctively without cooking their tyres and are putting in laps barely a few tenths different for the whole race.

 Practice and experience in setting up the rest of the car parameters is also required to make this work FOR YOU. Using someone else's World Record setup does not guarantee you an equally stellar performance.
The biggest factor in deciding race results is consistency and zero mistakes. Finding what works for you and allows you to feel confident about how you take the corners, lap after lap, will get you results. If you feel more confident with 60% front brake, you will be as quick and consistent as you can be.

One cannot make the jump from 60% BB to 50% BB in a single leap. Other parameters will have to adjust within the setup, so a slow gradual development is the way forward. Try dropping to 58% and after 10 laps decide what the car is NOT doing right in your opinion, then adjust other values to compensate, including how you are driving!!!. Always watch the laptimes and decide if things are moving in the right direction, not just for a single banzai lap where you leave 100mtr long black streaks on the tarmac at every corner, but has your average laptime over 5-6 laps improved?
The complex algorithm of GPL setups is what makes this game such a challenge, because altering one parameter almost always negatively impacts some other setting.       Good Luck

A new qually record had me making a tardy start from the back of the grid and by lap 7 found myself in 12th place ( amazing progress since I hadn't actually overtaken anyone ) then on the back straight the strain on the 3ltr V12 Honda cried "enough"  and popped a "header"  ( whatever that is ) and I rolled to a halt in a cloud of steam ( coming from me not the car ) .

Pity because uptill then I was in with a good chance of doubling my points tally .

Really have no idea how to get the rice burner going properly , perhaps I should try the 30/85 trick but I suspect maybe my choice of gear ratios was the worst ever .

[Philippe Girard]

Usually, I ride in 45/60, but here, in Hockenheim, I tested 60/85. I had a lot of fun in the big curve with this setting.
I am STILL at 49% BB.
But the most important thing in all these analyzes is that the pedals are the key!
As Tom Guérout always told me, the steering wheel is just an accessory, what is most important is mastery of the pedals. Especially in GPL.

[EvilClive]

FWIW.......I agree with Phillipe about the pedals, it is all about balancing the car and the grip.
 I ran 85/85 with 6 clutches in my Eagle for Hockenheim, 52% BB and the Sudkurve taken in 3rd gear. Brake early and a quick lift tucks the nose in and then carefully feed on the power so that I exit just about on the 10K red line to upshift to 4th. The 85/85 was a bit novel for me, but in testing I slowly moved to that value as I tried to protect the tyres and maximise that fast curve...it sorta worked  

[Cookie]

Clive you drove a very open differential with 3% locking f+r (ramp angels + clutches give a locking %)

I drove 30:30:1 (9% lock) what makes a controlled drift much easier for me

But this are only tiny bits of a whole setup you have to compose.

PS

Phillippe, a rampangle without the number of clutches is worthless!
The clutches multiply the locking effect, as Lee Bowden writes: only the locking percent count

I just used someone else's Mexico setup which worked out really well for me at Porto  (especially with retirements).

Same here (with more misfortune elsewhere) although I did click on the higher gears a bit, so the Honda could run for 6 laps without temps getting into the red.  Different matter with a tow however, I was seeing red & 204MPH at one point.

I got a lucky tow in the Q session & obtained a Honda PB.  Still only good enough to start from 9th.  Took advantage of misery elsewhere when I could.
Billy had to ease off at T2 and was absolutely mugged by the following bunch of cars.  I also had a comical run around the escape road.

Ended up 2nd for a bit. Ricardo had vanished.

I had a couple of Eagles pecking away at my back. Albert dropped away & had some close-running with Mikos for a number of laps.  Once past, he just drove away for a great P2.   

Still, happy to have gained some tokens & survived to the end!   The GPLRA lap chart suggests there was plenty of action everywhere.

Cheers,
Dave.

For BB I have tried different settings but always seem to work my way back to 52%.
Quite a decent race for me. Ferrari lacked the speed on the straights against the Eagle & Honda but the handling was pretty stable. Had various battles with Philippe, Albert & Dave R. My only real mistake was running wide at the Sachs curve. Without that I might have finished 4th, but happy with 5th.

[Pete Bennett]

I brake with my right foot so I'm a 61% Front driver . Seem to work.

[francesco]

Same for me, i use 60% but with 48(default) touching the brake my car fly away.

Fran, the race importer shows you drove as "Fran67 Molteni", which looks to be the right Player for the 67 F1 cars (assuming you follow the normal naming convention of a unique player name for each mod). This is the player that would have been selected in the iGOR window.
I suspect you developed your race setup using a different player. I'm sure if you look through the setups for your other players, you will find your race setup.
