traction control/ABS/stability

[pr0gress]

whats the point of turning these off performance wise? i can see race cars not having it (but why?) but your run of the mill production car all come with it, why turn it off in gt?

 

[LoudMusic]

By definition they lower the power output of the engine. When you turn them off you get more power to your wheels even if they're slipping. In some cases lowering the power for better grip can be a good thing, but when you're trying to go fast you want all the power you can get.

 

[enuttage]

In GT4? Can't speak to it.

IRL? Many reasons. And many of the same that were given in the 'Why Use A Manual Transmission' thread.

TCS, DSP, etc., try to self-correct when the car feels the driver no longer has control of the vehicle. Many times, the driver *wants* this result. For instance, when autocrossing, I have always disabled these features. When you're cornering and expect the car to follow a certain line, losing and gaining traction progressively, and the car suddenly 'corrects' for you, it throws off your entire driving line.

Same with launches. I don't want dialed back power to prevent wheelspin from a standing start. I want to be able to have full power available to me and then modulate throttle to control wheelspin.

Just my thoughts on why I'd turn them off in IRL. Dunno how well this applies to GT4.

edit: Make that the 'Perfect Shifting?' thread.

Most drivers in GT, myself included, find the ASM/TC get in the way. I don't know anyone who uses ASM who is a fast and competitive OLR driver. TC has it's uses and you'll see top guys using it on certian cars, but rarely over the 1 or 2 setting.

 

[LoudMusic]

Yeah, agreed. I sometimes have TCS set to 1 just so I don't have to feather the throttle quite as much. It takes the edge off.

 

[chameleon2]

I wonder if the TCM is the same for each car. Or does ie. the lancer have the ACD system and the impreza its own version of software? like in real life....or are the assist functions the same for every car.

And I found it hilarious that you can you put TCM on cars that don't have them in real life. Cars from 56 shouldn't be driving with computers.....

Given that ^^^ that is the case, I'd say it's probably an across-the-board cookie-cutter application.

That being said, these guys have surprised us with their attention to detail before, so you never know...

And it's oh so much more fun! Turn it off in all the cars you buy. The Cobra is just another car with the computer assists on. But when turned off...cor what a fun car!

Only cars I keep it turned on, although turned down are on ones with a stupid amount of bhp, where I just cannot control the wheelspin out of slow corners and lose time on the other cars.

like the cerbera speed 12? that thing is crazy, you can spin the wheels up thru like 5th gear

 

[Red Raevyn]

Haha, I agree, turning it off makes it a lot more fun. I remember a license test in Gran Turismo where you did the slolem on the test course in an Ruf, first with TC on and then with it off. I actually went quite a bit faster with it off, because that's the driving style that suits me, haha >_<.

want a real challenge..

speed12 + N1 tires + all aids off on Laguna

It will drive you insane!

 

[GT Freak!]

So is their ABS i GT4? I have had the ASC off for a long time, actualy feel like i am driving, not the computer. Also i have the TCS on 1 or 2 on my high BHP cars like the le man cars, but other wise i love having a FR car with around 300bhp+ and simulation tyres! So much fun! I cant wait till i get the M3 GTR in GT4, whack on some street tyres and start smokin it without any aids rounf the nurburgring!

how about power stearing? what is the justification of taking this away and not having i on race cars? why is it u have to fight the wheel in a civic, or any of the other cars that are regular production cars that normaly come with power steering?

When this is a point, would my DFP Wheel react different for a car with or without power steering?. I bring this up as I HAVE built and driven real high performance and race Porsches, but find no difference in the reaction of my DFP wheel at all, for the Porsches in GT3, but have yet to see how it is in GT4? I know that RUF is supposedly the leader in Porsche tuning ( which to stop you who do not know RUF's history and will start going at me !!! , I will only say I know they are accepted as a manufacturer under their own name due to the extent of their production statistics compaired to an original Porsche) but a normal Porsche is quite light at the wheel, but my DFP F,I,N
gets out of order as if I was clipping the curb the whole time, but I KNOW I aint so WAS UP with the game physics for this point in GT4? Is it the same?

Well beside that point to all that try 24hour races in one sittin like AE86. Hat off to you all, see you there !!!!!!!!!!!!!!!!!!!!!

Kind of like how all cars have ABS in GT3, Is this the case in GT4 also?

 

[animateria]

ABS is usually turned off cause it just seems to cause understeer (I think)... But I just have to have it on Several Cars since they(Me?) cannot control The hp...

For example... The Vette on GT3 drives like a dream and I don't need ABS cause it drives extremely well without it.... (At 811 hp)... But the Mustang can't handle the 6xx hp it has and spin out way to often... I have limited slip diffs and ABS to correct that from happening... And It works well enough for me...

TCS? Most cars I drive have them up 1 or 2 depending on how I like the feel of the car... (As an exception Mustang has 5) Without a Wheel its hard to control the throttle... so I need to correct it by using TCS...

I'm guessing all of these systems are not needed on a wheel because you can precisely control the throttle... I want a damn wheel!

 

[SavageEvil]

I guess that was an internal decision to make all the kinds mildly driveable for the masses, but they should have the option to have the car in proffesional mode, where the cars are exactly true to life, if it has no ABS, you will drive it without it.

Always found it odd that i couldn't disable ABS, and found it weird that LeMans racers had ABS at all.

Hey EVERY CAR in GT3 has ABS, you cannot DISABLE it!!!!!

A LSD will make your car not spin out?

Thats a new one.

In the environments I race in? Only one reason. Weight. A/C, cruise control and power steering would be quickly out the door (or out the hood) if I were a competitive driver and the class specs allowed removal of these things.

And once you're moving more than parking lot speeds, or even then in a light car, power steering is totally unecessary. The exact reason the Lotus Elise is sans power steering (can't think of any other currently produced U.S. models that don't have it). The car is not really heavy enough to warrant the assistance in said Lotus.

I may be misunderstanding you, but 'fighting the wheel' is generally what power assisted steering is improving upon/removing.

Nah... I read the descritions... More stable but understeery or something like that... Well... If it understeers I woudn't have problems of it spining out would I?
(Heck I just read the description I don't know much...)

In a RWD car, this makes sense to me. You're getting single-wheel traction. It tends to throw you off-balance pretty quickly.

Even in a FF car, it'll make you compensate/overcorrect.

LSD-less problems are why cars like the new MINI Cooper S, the SRT-4 and the Lotus Elise either have or will have LSDs. Heavy driving competitors are hindered by serious traction issues.

edit: It 'could' throw you off-balance pretty quickly, especially (I imagine) coming out of a corner hot, and in an 'overpowered' car.

 

[RobcioPL]

LSD on a FWD car helps the car come out of a corner faster.

 

[enuttage]

Yup. Otherwise you have single-wheel traction.

The MINIs are horrible about it, for a modern car. When my wife and I were autoXing hers, our standard 180 at the end of the runway we were using usually resulted in some really cool burning rubber on the front right, coming out of the turn.

Cool looking. Slow driving.

So is there ABS in gt4? I Mean can you switch it off? Not like gt3

 

[ak]

There will be ABS in GT4. It might be like GT3's where there are different levels of settings for the front and rear wheels.

 

[Minnesota01R6]

brake balance is not the same thing as ABS. brake balance controls the amount of hydraulic force applied to the front or rear pads. ABS is the car's computer detecting lockup and then pulsing the brakes at 60 times a second or whatever so that the car is controllable.

 

[kjakan.no]

I always turn of asm beacuse it seems to wear my front tires out quicker. And it is disturbing when it suddenly kicks in in a corner. The TCS can help you out a bit on high pwered cars if you use the DS2, but I think should not be nessary if you use a wheel.

Since when has an Elise been FF?

Mid-engined I think you will find.

 

[Div is back]

So can anyone that has GT4 can confirm that ABS can be disabled?

 

[enuttage]

I never said it was an FF car . Go back and read my post again. However, it may have been unclear. I should've separated the first sentence of that paragraph from the rest and had an unclear antecedent (I'll go back and fix it for you to help you better understand it).

I said what a lack of an LSD will do to a RWD car, and then said it affects a FWD car as well. Then I listed some example of various cars that don't or didn't have LSDs that do or will soon (SRT-4 and MINIs now have them - the MINI's is an option, Elises will most likely have them by next model year).

I'm currently selling Elises as an occupation, so believe me, I tend to know my way around them. Not even trying to be nice, eh?
