Understeer

Forza Motorsport Legacy Motorsport

Lads, I’m experiencing a hell of a lot of understeer at the moment and don’t know how to fix it. Wether it’d be part of my tune, the game in general or my steering wheel settings/assists (Thrustmaster 458). I used to play Forza heaps back in the day but using a standard controller and have never had an issue with understeer on the game. This is the first Forza I want to get into using a wheel.

What do you guys suggest? I don’t know if I theres already a thread about this but I couldn’t find one, which I’m quite surprised by, as it’s pretty much unplayable, for me anyway.

I’ve changed the steering to simulation and it’s seemed to have helped a small bit. Still got a lot of understeer though. I’ve got the same wheel settings as Stella Stig.

Get a car which has been tuned by somebody really good at tuning, like for example Raceboy77. It’s a quick way to see if it’s your tuning, or driving.

This to a point is correct but remember Raceboy is a controller player and sometime controller tunes dont feel just right on a wheel. Also remember so people are just really fst and a tune is not that important. Try looking on the leader boards for cars you want to drive and tunes for them. Then look at the tuners name and see if he she is a wheel tuner. It a bit of a pain to search sometimes for wheel tunes but it can be done.
I would like to think it is your setting and the fact that the wheel is not as quick as the controller. Im a TX user and always felt it was understeer based using the wheel so tunning I added more oversteer than one would expect.

Good point. I forgot about that.

Hi.
While tuning driving pull up your telemetry and look at the four green friction circles or tyre heat to see if the the fronts are going red very quickly or overheating.
If they are the chances are your wheel rotation is to low and your oversteering the wheel.
I am having a lot of problems setting my wheel up to how i like it. This game is terrible for wheel users it’s either to sensitive or dead feeling.
The settings i’m using at the moment are.
DOR 540 on wheel and 570 in game menu
In the fifty’s for vibration.
71 for force feedback.
All deadzones 0-100.
Iv’e been playing with sensitivity 1 and 2 and decided 1.5 would be ideal as 1 is a little to sensitive and 2 the wheels don’t match as i drive in cockpit.
Hope this helps,good luck.

try adjusting you front vs rear tire pressures or changing you front vs rear toe. i set my front toe - (pigeon toed) and the rear + that way the outside tires where the weight shitfs more grip to in the turns gets more traction forcing the front more into the corner and the rear more out further forcing the front of the car in. but that defect can be negated by steep banking like on daytona.

If the game is anything like real life in how it models suspension, which I believe it is because Dan G has stated every car has a different suspension set, your toe set up is neutral.

On real cars wheels that are driven toe in under acceleration. If you have a rwd car and you accelerate, if the toe was set to 0, you will be running a .1 in.
Conversely, non driven wheels toe out under acceleration.

I personally set my toe to this effect, because generally speaking you should always either be accelerating or braking, to do neither is wasting time.

Make sure you’re taking the line correctly and using your inputs wisely.

Do you need to brake or can you release the throttle and slow down enough with a down shift for example?

you have to do a lot of tuning to make the cars drive how they did in the 360 versions of forza.
i give just about everything the following settings as a default before i test drive it just to get it to steer the way i want it to. (which is a little loose, aggressive, and snappy)

28 front psi
29 rear psi

1.5 front camber
1.0 rear camber
0.3 front toe out
0.1 rear toe in
6.0 castor

then if i still get understeer, especially on a long turn, i do the following
soften the front springs
soften the front sway bar
add front downforce
add wider front tires

also keep in mind that if you have high rear downforce, 375 wide tires in the rear or a rear differential set at 80+ accel, or anything that heavily favors the rear traction, it’s going to push the front tires through the turn. you have to balance the traction. a loose over steery car is far easier to drive than a massive understeering boat with butter tires on the front end.
loosen up your differentials. i usually use around 50-60 accel for the rear
if it’s awd, send more bias to the rear. i use about 60-70% depending in the car.

i use a lot of other defaults for my driving style, but i left all that out. so all of that above is jsut for steering response and sticking the turns for the way i like to drive.

is it a typical leaderboard tune? omg no. but i can drive it like the tasmanian devil and usually get into the top 1%.

I too am experiencing a lot of understeer. I have the Thrustmaster TX458 and cars dont feel as they have any weight to them and I am loosing traction around most turns. It feels very different from Forza Horizon 2 and I have been playing a lot of Project cars so getting used to it may be an issue. Either way something needs fixing because I dont remember having this much trouble driving in Forza.

Thanks for the advice, everyone. I’ll look into tuning setups when I can, and I’ll try adjust individual things that may enhance my experience.

And Zoidberg, I actually found that Project Cars has a lot of understeer too, I swear it’s not just my driving. I know I can take the lines and so on.

You could try increasing negative camber or softening the ARBs …

14

Is the 458 the Thrustmaster with the bungee cord & no force feed back? Because when you turn a steering wheel beyond the point of grip the front wheels will then skid giving you even more understeer. This is not possible on the controller because of the speed steering assistance that is not on the wheel. If that’s what is happening you should be able to see your front tires cooking up in corners.
I find forza has a very fine line between the edge of front grip & turning past that point. I’m not sure you can feel that point of grip with a wheel with no ffb can you?

15

What car are you using and in what state (tuned, stock)?

Are you sure you’re not mistaking understeer with the resistance of the front tires during normal cornering? Understeering should be felt like a bit of a cliff when it comes to cornering, the steering wheel becomes very light and additional inputs make no difference, you have to wait for tyres to regain traction.

Lots of cars can go through understeering with no problems, if you take a stock FN2 Type R around the Nur, you can muscle it around corners and the limited horsepower will never throw it too far off line. Understeer can also be used to your advantage with FWD, AWD or very neutral RWD cars. I prefer understeer to oversteer, understeer is stable and predictable, it can be recovered. Usually, when you have strong oversteer using a steering wheel, you’re not going to recover it.

I suggest trying the Honda Civic FD2 Type R (2007) and the Mitsubishi Lancer Evolution 6 in stock trim for examples of manageable understeer.
