so if in 200 degree mode on gt3, you have to turn the wheel all the way while driving through a corner before the tires would give way, but also when you are driving 5 mph and you turn all the way the tires turn almost all the way on the car...then in 900 degree mode on gt4, does that mean while going through a turn you will have to turn the wheel all the way to one side to get to the point where the tires are about to give way or is it gonna be like in a real car where you only need to turn the wheel a little bit? and what would happen if you tried to turn it past this point?
 
actually im considering returning it, i have 30 days to return it so yea. its kinda fun to use, but i like the controller better. im just gonna return it and get my money back then when gt4 comes out ill buy it again and try it on that game.

I've done some testing about the steering ratio of different cars, and found that all cars have the same rack and pinion in GT4P.

are you able to change it at all? I just don't see how you can use the paddle shift while arm-over-arming the wheel to take a sharp corner. It is easy enough for me to do in real life since I don't have paddle shifters on my STi, but I think it would be unrealistic to ecpect us to be able to shift like that in GT4 with the DFP.

then in 900 degree mode on gt4, does that mean while going through a turn you will have to turn the wheel all the way to one side to get to the point where the tires are about to give way or is it gonna be like in a real car where you only need to turn the wheel a little bit? and what would happen if you tried to turn it past this point?
If you do not drive on the limit, and the drift angle of the tires is low or zero, then you turn the DFP like e.g. only 60° for the first RH corner in Tsukuba.
When you drive on the limit of adherence of the tyres, you will turn the steering wheel to the point where the tyres are about to give way, that's correct. That point is - on street tyres - at +/- 90° to 135° (I did not really measure this out, so it might be some ° wrong, but it's the order of magnitude). On slicks the angle is smaller.
When you go beyond this point, you get understeer il almost all cases, i.e. the front wheels loose grip, and you turn the DFP further without turning harder.
In one very particular case, there is a school example of oversteer : with the 2001 Mobil 1 NSX in the long RH corner halfway on Fuji. This car has so much downforce that it allows to go full throttle through that turn. While you are accelerating through the turn, you actually don't have to turn the DFP tighter. You even have to steer less tight with speed going up! For those with GT4P and an ARMax or AR2v2 it's definitely worth trying out!

Unlike e.g. in Grand Prix Legends, it's impossible to change the steering ratio in GT4P. I think the reason you mention is exactly why there's a gear stick on the DFP. However, as far as I remember, I only had to use the stick in few occasions : mostly when I made a spin and have to manoeuvre back on the track :)
In "normal" conditions, the steering angle does not become so large that you can't use the paddles, even on street tyres.
 
Chime'n in cause I just got my own DFP ! (got raped at best buy though 👍 ) I have nothing bad to say at all about this wheel; very rugged, <2 degrees of dead force feedback zone (that's a very liberal number, mine has probably <1.5 degrees right now), and comfortable design to the wheel.

I was wondering if any other users have noticed an increased realism to the replays, (I'm playing mostly bmw demo and some tgs demo - I'm holding off on tgs for when I really can't wait for the game, or for when somebody figures out how to nix the time limit ;)), but it just seems like you can see the weight and momentum of the car far better in the replay when using the wheel, as compared to DS2.

Honestly, on my first couple of DFP laps on the 'ring with the 1 series, I would simply not breathe going through various sections because it was so intense and demanding, I couldn't believe the change in my view of GT, there's so much I believe you're not experiencing with just a dinky DS2 controller in your hand.

I also already built 80% of my driving setup. It has a honda del Sol seat and the feel of it is as real as it gets w/o a dashboard, door, center console, 5spd, etc... The other 20% of the build-up is going to be done in completely re-working the pedal platform so that I have hanging pedals with a nice dead pedal and the right distance to the floor and back-panel below the pedals. I'll post pics on the other thread as soon as I flat-black paint what I have finished and working so far.

:dunce: You didn't measure that, did you?

Because, if you did, there is me and k2racer having to change our DFP wheels ...

The main problem is the FF-less zone however. I took an angle-meter to measure how many degrees this neutral zone really is.
It varies between +2.5/-2.5 and +7.5/-7.5, and that depends of :
- tyres : smaller angle with slicks (seems logical)
- speed : smaller angle with higher speed (seems logical)
- force applied : I mean, if you apply a sudden force, the wheel turns over a bigger angle before the FF has the time to start working.


Could you measure the dead FF zone with an angle meter, and give feedback?
 
has anyone checked these out for sale here in the US?! I picked one up over the holiday weekend and will post a pic of my cockpit tonight.... The chair is perfect though! I'm loving it.

This probably has been posted but i've got a question regarding the wheel:
Are the pedals pressure sensitive (analog)?

the pedals are analog - the FARTHER you press the more gass/brake is applied. However, as someone has pointed out, they are not really pressure sensitive - it's just as easy to press the brake the last inch as it was to press it the first inch. This can be bad for trying to brake at impending lockup, but since I've only played with GT3 and GT3 has ABS that you can't turn off, I usually just mash the brake to the floor. Playing GT3 with TCS and ASM turned off is actually quite easy for me now that I am used to it and I have gotten pretty good at rolling on the throttle out of corners as my available grip increases.

Basically, there is no force feedback in the pedals...just a spring that pushes them back out at constant pressure all the time.

$79.99 @ a local Best Buy. You can get them on sale online off of www.bestbuy.com for 69ish rightnow. I think I'll start a new thread on the chair later today with cockpit pics.
I thought it was way more exepensive and it looks sweet but I'm not going to buy a wheel some time now,maybe for a couple of months! :)

I don't blame you for waiting to get a wheel, hey they might have the DFP:2 out before GT4!! But yeah the chair is cheap and well made and very comfy just to rock and lounge in.

Yeah I can measure it, but I know angles pretty well and it doesn't look anything more than about 2 degrees. If the play is bugging you, there probably is a malfunction.

Question, how much does this dead zone affect your ability to keep the car strait when you're on flat track ? Because I go like I'm on rails down the Nordschleife strait.
 
I only have GT3, but I have absolutely no deadzone - the wheel wants to shake back and forth fighting with itself even when I am stopped. 60% or 100% doesn't matter. I am hoping this is a GT3 thing and not a DFP thing.

The dead zone concerns only the FF. If I move the steering wheel inbetween e.g. 1°, the front wheels turn 1°, but with no FF.

I'd appreciate if you could measure your play.
 
i just got it today ...hum.......SSSSOOOO happy with it .
I have some questions about the degree! normallly

1. Is this steel wheel automatically set on 200 degree in any racing game???? (expect play it in
GT4)

2. this wheel got two front light, right?? but I dont no why the right light doesn't work ...? is this happend in GT4?? Coz I used it in NFSU2----->this game really suxs

NFSU2 only supports 200 degree steering, so both lights won't light-up, as a matter of fact I think GT4 is the only driving game that has/supports 900 degree steering, someone correct me if i'm wrong.

The right light indicates that you are in 900° mode or not. Look at the first post of this thread, or in your instructions manual, how to switch between modes.
 
Ok, so I know my Driving Force wheel has less radius than the 900 deg DFP...but is it worth the upgrade? I get that it's more realistic, but as someone pointed out, how insane is it going to be to downshift through a hairpin turn while cranking the wheel...?

*Ps, has anyone bought a refurbished wheel?
*PPs- if I decide it's worth it to upgrade, I might have the original DF wheel for sale...
 
Im pretty sure the way the new DFP 900 works is different to the old DF.
I think with the old DF, it works in a similar way to the DS, the steering turns gradually, with the new DFP the steering input is direct.

This is what i heard elsewhere and dont have the old DF, so i could be talking utter twaddle :)

Actually NFSU2 on ps2 supports 900degree mode and man does it make it better.
 
Is anyone having trouble with their DFP locking up? Mine seems to do it at least once a week. The DFP goes dead, the game thinks I have the accelerator full-on, and it won't turn. I have to press the start button on my DS2 controller, unplug and plug back in the USB cable to my DFP and then everything works just fine again.

Any help would be much appreciated.

Fortunately this did not happen here untill now :scared:
 
I am getting the DFP on friday, but Im abit worryied as many people have had problems, Does the DFP work fine for most people here?
