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 Hnic "Will Hom" <[email hidden]> a �crit dans le message news: [email hidden]...

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 :) Andre

Andre, This I don't understand. I have the "pressure sensitive" setup myself, by putting in a rubber-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? JensSchumi 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.
