Braking Too Easy?

by Michael Sisso » Fri, 08 Feb 2002 11:51:05

Hi all,

I have driven about 50-60 laps in F12001 and have noticed that the
braking seems too easy. I have *all* help options turned off (unless I am
missing some super secret options.)

I am used to the GPL cars and having to be oh so careful with regards to
steering, rpm, and brake inputs when braking hard. Add in gradients and
GPL is even more challenging to the hard braker.

Any time I brake hard in F12001, it seems as though there is no way to
get the back to trade places with the front, and all my experience with
GPL, real life driving and reading (Going Faster) whispers to me that
this cannot be correct. Heck, I have steered in one direction or another
and all the car does is slide straight on. With all the weight transfer
it doesn't seem right.

I was thinking maybe modern F1 cars are just like that, but I just tried
out the GT mod V2, and it is the same deal.

Anyone else notice this?

Michael,
I think that once you start taking wing off you'll be able to get your
car to swing around anytime you want! Changing brake bias alone should
help to get you spinning in a corner.

Wow! tell me your technique. After many months of F1 2001 I wish I could
find a way of avoiding the back trading places with the front under braking!

I have the same problem as the original poster and my technique is
simply 'mashing the brake down all the way until i slowly work the gas
pedal'.  This works pretty well since the brakes don't lock up above
50mph.  No reason to use anything but full pedal.

..but stability goes if you brake hard and change down the gears quickly!
serious amount of weghtchange forces in place there. watch the back coming
round then!

Keep some slight pressure on the gas, and keep the revs down (i.e. don't
change down too soon).  This is realistic, I have seen comments from F1
drivers that you cannot just take your foot off the gas and expect the
car to go straight.

For the original poster, try boosting the brake pressure.  That option
is not in the normal setup menu, but it can be done with Turner's setup
tool, which you can download from http://members.rogers.com/nwalkz.  I
think there is also an advanced options menu available somewhere that
allows you to do it.  Even with full brake pressure you will find it
hard to lock the bakes at speed, due to the high downforce on the tires.
This, too, is realistic.  But full brake pressure did seem to decrease
my stopping distances.

No - I'm spinning all OVER the place under braking...

Eldred,

I was spinning a lot too, until I realized that it's the same as GPL,
only everything is happening much faster, and with less margin for
error.  So you have to keep the revs down under braking and turning, and
you may need to keep some very light pressure on the throttle at the
higher speeds where the braking force (and consequently weight transfer)
is greater.  Also I think you will find that the GPL technique of
keeping the revs low, using a lot of diff. lock, and pushing the car
through the turn with just the right amount of throttle still applies,
but again with a smaller margin for error.  Same skills, different feel
and timing.  Knocked a couple of seconds off my times at A1 and Monaco
after I realized that.  My lap times still suck, but less than before.
;o)

Regards,
Hal

Yes Tony, I believe you have...  I've never spun on the 401...THANKFULLY. :-)
But, I almost hit a bridge abuttment in a rainstorm at night.  The road
narrowed by a couple of feet almost before I realized it...whew!

I haven't totally gotten used to using the throttle while braking, even in GPL.
 I just recently started trying it.  So, it will probably be even tougher in F1
2001...

Heh, you could probably spin for several hours on the 401 before you hit
anything, it's so flat out there....

Sorry Eldred - just trying to enhance the reputation that started
the whole St. Eldred thing!

Incidentally have you come to any conclusions with the controller
settings for F1-2001.

I have yet to find that magic "feel" setting - but judging from
other posts others I feel I am missing something - any further
thoughts?

Cheers

Try setting speed sensitivity to 5% and also X-axis to 5% - you may need to
play with those numbers depending on your wheel, but that should be a good
starting point.

I find this hard to believe and I think people saying this are
rationalizing a huge flaw in F1 2001's physics modeling.  Within the
past few years I can remember several instances in real life where
people locked their brakes and/or got incredibly tail-happy when
braking.  In F1 2001 you can HAMMER the brakes, with the brake bias
set fully to the front, and until you slowed 50mph (or downshift too
quickly) it feels no different than braking with the bias set fully to
the rear or anywhere in the middle.

If your argument were true, then a car with a front/rear wing ripped
off should be able to lock up the brakes above 50mph, since downforce
would be reduced dramatically (what with the ban on ground effect).
Yet, without a front or rear wing, I still can't lock the brakes up
above 50mph unless I frantically downshift too fast.  To go further,
by the same argument, if I were to lose my front wing and I have the
brake bias set fully forward, then I should have no problem locking my
front wheels at any speed.  But I can't.  Because the braking model in
F1 2001 is flawed.

Also, the downforce/grip keeping the brakes from locking argument is
flawed when grooved tires are taken into account.  There is less grip
now when braking then there was the last year before grooved tires
were introduced, and yet people could lock their brakes up then too.

For information's sake (or at least demonstrating beyond a doubt that
I'm an idiot =), are there any legitimate articles on this phenomenon
on the net anywhere?
