A gtr2002 driving style question...

GTR2002 tyre squeal, brake lock-up and axis sensitivity

Jon asked how much tyre squeal was acceptable in GTR2002, and Marc Collins asked why he could not lock the brakes at speed. Damien Smith and Jan Verschueren explained that downforce at high speed stops the brakes locking the wheels, as in GPL. They also clarified that 50% axis sensitivity in F1 2002 gives a linear response for wheels and pedals.

How much should I be squealing the tires in this type of racing? Is all the way through turns ok, or just every now and then?

Excellent question. And if you could (this knowledgeable respondent), please also tell us if it is normal not to be able to lock up the brakes even with your foot to the floor...

Quite normal if you've left the ABS setting too high. Failing that, it might be a controller sensitivity issue. Gerry

> No ABS, obviously! Ever heard of a race driver going into the first turn with cold brakes and not being able t stop? That's the way these brakes work. In GPL, if you're doing 320km/h and hit the brakes on full, they don't don't lock-up immediately despite having much less grippy tyres and miniscule downforce compared to these GT cars. I'm sorry I can't give a scientific explanation, but I can assure you that these brakes perform true to their real life counterparts.
seems like that would have to be the aforementioned controller sensitivity. After I turned off abs, it took me a while to figure out how to keep from locking them up. I couldn't even go 1/4 down without locking them. "Gerry Aitken" <[email hidden]> wrote in message news:[email hidden]...

So are you saying that the cars constantly have cold brakes and they never warm up, or are you saying that the friction force of the brake pads is not enough to overcome the inertia of the spinning wheels at high speeds? JB

No, he's saying that the download generated by the aerodynamics is such the brakes cannot provide enough force to lock the wheels at speed even if full braking is applied (there is a limit to how hard the virtual driver can push the pedal in the game). As speed decreases so does download (with the square, actually) so you have to release the brake progressively as you slow down to stop the wheels from locking. Also, as you start turning in, total grip of the tyre is being shared between braking and cornering so you have to "trail" out of the brake even further to prevent lock-up. Another phenomenon which can be observed in the mod. For best results in this area, IMO, the axis sensitivity for your pedals must be set to 50% (linear) in the game. Jan. =---

I'm saying that even when they are at optimum temperature, they don't have the friction force to instantly lock the wheels. Not even the Porsches ; ). As I say, it's the same in GPL - even those '67 cars with their huge brakes can't lock the wheels instantly at very high speed.

But shouldn't linear for split-axis devices like pedals be 0%? Correct me if I'm wrong. Right now I have 50% axis sens. for my steering and 0% for my brake and gas (Act Labs Performance Pedals). -- karkrazy AT softhome DOT net http://karkrazy.m4driving.sm

The X-axis appears to behave differently to the other axes. If you depress the pedals in the axis setup screen, you can prove to yourself exactly what's going on. With your throttle and brake set to 0%, you'd find that

If you were to set the pedals to 100%, you'd find that all of the braking/acceleration would occur within the first little bit of travel. The pedal/steering sensitivity numbers are relative to their stationary positions. Unfortunately my wheel doesn't have enough resolution/travel to use 50% (full linear) steering so I have to back it off a little. 50% is very important for the pedals - particularly the throttle.

Okay, you sold me on the idea. :) I did some testing in the axis setup screen and noticed what you described. I guess this would be true for the clutch as well? Okay so 50% is linear, 0% is non-linear, then what is 100% then? -- karkrazy AT softhome DOT net http://karkrazy.m4driving.sm
