HI !

I am a GPL fan since that game has been issued, and nothing else matches it
since, IMHO.

I did not hear of CTFJ utility

Is this hardware or software ?

If it is software, where can I download it ?

Thanks for help

This was what I said here on RAS more than a year ago, but Randy
Cassidy (himself :) then replied to my post, saying that this wasn't a
really good solution.
The problem is: Especially at non-flat circuits, like da Ring for
example, this doesn't work. When you have to brake when you are
driving up a hill, you have to press the pedal less far to brake than
when you have to brake when you are going down a hill.
So it's important to set the maximum lockup so that you can still
brake when you are going down a hill. But that means that for the rest
of the circuit the wheels will lock before you hit the braking pedal
at maximum travel.

So, it helps a bit, but it's still far from the perfect solution.
After reading that reply I bought myself some decent pedals (the CH
pro pedals), put a squashball under the braking pedal, and since then
I'm really in braking nirvana :)

Hey, wait a sec..
I remember talking about this more than a year ago here on RAS, And I
just remembered that the topic 'braking nirvanna!' was also the same..

Is this some kind of timewarp?

Andre,
This I don't understand.
I have the "pressure sensitive" setup myself, by putting in a ***-doorstop
and tweaking the locking-point with a trimmer.
I can feel differences in tire-lock at:
different tire temperature and believe it or not:
different fuel loads

I cannot feel any difference when braking uphill or downhill.

Am I missing something?

BTW: Extremely interesting that you can tweak the GPL-brake-travel with CTFJ. I
tried this with DxTweaks to get rid of my trimmer, but wasn't successful.

As an example I want to use on of the Ring corners, but I don't know
the name. I'll try to explain which corner I mean:
After the jump at Flugplatz, you have a full speed straight.
Then a sharp bend to the left.
Then a sharp bend to the right, after this corner you immediately
drive under a bridge.
Then you have a fast left-right-left section.
At the end of the corner is a fast lefthander, this is the corner I
mean.

Ok, you enter this corner at full speed in 5th gear. Since you're
going steeply uphill, you only have to press the braking pedal a
little bit. If you press further the wheels will lock up.

If you're braking on a downhill section you have to press the braking
pedal much further to lock the wheels.

So the 'tire-locking point' varies and using CTFJ isn't the perfect
solution for this.
