How much steering lock does the GT wheel use?

[INSANERAC3R]

I have a gran Turismo wheel from Logitech, Gran Turismo Driving Force wheel. Ive been playing a few games that let you adjust the amount of rotation the wheel uses, maximum of 900 degrees. It really feels like the wheel is not using 900 degrees in Gran Turismo.

How much does it use? I doubt its 900.

GT5 uses 900 degrees of rotation.

GT5 uses 900 degrees of rotation.

Are you sure? It feels more like 720 tops

It also feels like it gets less and less the faster you go in GT5 like its not linear either, at least not fully/

Yes I am sure - because GT5 has no internal way of modifying the degrees of rotation it will default - in the case of the Driving Force (Assuming you mean the GT) this default value is 900 degrees.

The sensation you're describing is the decaying sensitivity as you turn the wheel further.

The driving force wheel only has 200 deg total travel, if you have a dfp or a dfgt then it's 900.

My assumption was that he meant the DFGT since he described having 900 degrees of rotation in other titles.

 

[INSANERAC3R]

Yeah the Driving force for Gran turismo

It feels like PD calibrated it, and did not give us the ability to adjust it, I feel it is not 900 degrees by what happens in the game when I turn the wheel, even though the side of the wheels box says 900, it feels like PD calibrated it behind the scene to 720 or even less.

The decaying sensitivity as you describe sounds like its not linear , this further increases the possibility 900 full rotation is not used.

You could try messing with the 'controller sensitivity' setting, some claim it has profound effect while others cry placebo effect.

 

[steiner]

would it not server if you go into 3rd person view and have aclose look at the wheels and see when they stop turning?

I thought about that, but the wheels on the car move much more when the car is at a standstill vs in motion. It might still show a degree of no movement after a certain point, so I will test it out anyways. Ive tried to figure out a way to test while the cars in motion to see if there is visual motion after 350 degreese from center, but Im drawing blanks.

I do not think it defaults to 900 if un adjustable, look at Dirt 3 for example. You cant increase the degree of rotation, it maxes out at something like 360 degrees (at least on PS3) and there is no specific degree of rotation setting just settings to speed up or slow down the input acceleration or delay wheel input vs vehicle reaction.

 

[arora]

Why would the wheels turn less vs input while in motion? Maybe if you have aids like asm or active steering I guess.

I dont use any aids. But stop the car, turn the wheel 360 degrees and look at how much the turning angle of the wheels is high, but make the same amount of rotationon on the wheel while the car is in motion and the wheels dont turn to the same angle, seems like less angle the faster you go. No assist at all, no power steering, full FFB No ASM, or any of that, I even take the time to flick the track side to real. Could be PD is sneaking in hidden assist?

All photos were taken 'overspeed' to exaggerate the conditions and were taken at similar angles from memory to the best of my ability.​

With better wheels, GT5 has 100% linear steering. Try changing in settings to "Simulation", they say it doesn't change anything, but I've been using it since the beginning just in case and haven't tried the other options. It's in the controller options menu.

 

[Aquarelle]

Steering Types ("Simulation" "Professional" and "Amateur") have zero effect on any wheel with more than 200 degrees of rotation - it will change nothing; the same goes for Controller Sensitivity.

Nice photography UrieHusky.

If you have a Fanatec GT3 RS you can adjust the steering degree to your liking from 90-900

I posted this at another thread, not sure if anyone read it, but here goes :

Controller steering sensitivity does affect wheels, maybe all wheels, I have seen a post somewhere here on GTP which shows on video, how it affect wheels - he was driving Ferrari F1 car. I quoted it once, forgot which thread it was from, will look into it again

Okay, found it :

I am not sure if this is true, but here is another post from a member about controller sensitivity affecting his steering wheel :

I know this is an old thread, i was just searching and found it but it hasn't seemed to have ended with much factual information.

In Gran Turismo, the steering lock on your wheel is set to 900 degrees for all cars, however, the front wheel turning angle is set correctly to correspond with the steering wheel lock. The F1 cars feel very good and drivable to me after the spec 2 update. Just because the steering wheel turns a full 900° doesn't mean that the steering ratio is increased in the F1's.

In real F1 cars the steering ratio is fully adjustable within a certain range, meaning you can adjust how much the steering wheel turns and how much the front wheels turn, some drivers like Fernando Alonso and his team mate Massa both prefer a higher ratio (more steering). This is somewhat possible in GT5 by adjusting the steering sensitivity within the "Driving Options" in the track menu.

Here's a video of me with the T500 with F1 wheel doing a seasonal event at the Nurburgring 24H layout. I have all the driving aids turned off, this includes the ABS at 0, the steering sensitivity is at 0 as well and i actually prefer it this way because it allows for more precision, it feels like the front wheel angle is about 14/15° at 390/400° steering lock, which is realistic. If you increase steering sensitivity, it increases the front wheel angle while maintaining the same steering wheel lock which shortens the ratio, same effect as in real life:


Also, as a visual reference, look at this video of Fernando at the Ferrari test track in the F10:

Just did some testing, and found out the lower the steering sensitivity, the less you have to turn a wheel to do a turn. -2 did sharp corners with a lot less turning of the wheel when compared to 7 at Monza, I thought it was the other way around, so I now have a way to get faster lap times.

At least now I know you can change it, with the f1 car I had to crank that thing to get through the first chicane.

This has helped me and a buddy with G27's out immensely!! Good call on the info!!

G27 support 900 degrees i think . not the DFGT

 

[Aquarelle]

Nice photography UrieHusky.

Thank you.

The DFGT is a 900 degree wheel.

 

[Mr Evil]

The DFGT is a 900 degree wheel.

nice . but i like G27

I was hoping someone would post that, I searched a bit for the original thread but had no luck.

I'm not convinced or concerned tbh, gt5 worked fine for me as far as steering wheel inputs go, iirc I used to use 4 on the scale with a dfgt and was able to punt all my mates just the same

Could it be that it only works on certain wheels - T500 or cars, like the F1 in the video ?

Possibly, I've never found it to have any effect what so ever on the wheel and it could be people adjusting their lines without noticing to convince them selves that it is in fact the case.

nice . but i like G27

Well that's nice, however we're not discussing wheel preference.

 

[INSANERAC3R]

Those pics show clearly its the same at a standstill and moving so it was just in my head. But with all those pics did you test any to show a difference if any around full rotation?

I'm not sure I understand the question, sorry. Could you be clearer?

Wheel turns 450 degrees in either direction from center. Is there definitive motion on the front wheels from like 400 or 425 to full 450?

My suspicion is somewhere between 360 and 420 it stops. Im NOT saying its like this I'm just suspicious.

Yes, the last two photos depict "Full lock" (450 degrees of rotation to the left). 👍

The difference isn't easily noticeable since it's only an extra 90 degrees of additional rotation over the 3rd and 4th photo but it's certainly there to the same degree as the difference between 90 degrees of rotation both at a standstill and while moving and straight on.

I can take a photo at 180 degrees and completely straight if you need those references, however I'd imagine the point has been proven well enough by now

what about rate of rotation, possibility its progressive decreasing rate or increasing up to full lock?

 

[LERK84]

900° Logitech wheels use 100% linear steering (no change in "rate of rotation" of wheel) 450° one way on the wheel is full lock on all cars, 225° on the wheel is half lock on all cars. Obviously some cars will have more steering lock than others. Also Drift trial gives cars an extra bit of steering lock as opposed to Online, A-spec, or a Time trial.
