Downloaded the 2 files and they both say GT4, now in the link you list GT4, GT5P and GT5 but the documents itself only says GT4, should i assume it works the same in GT5 as in GT4 and thats the reason nothing is updated? Im confused if this is the correct guide or not, could you please verify what is what?

cheers

For the most part it transfers to GT5... we're still debating the changes from GT4 to GT5 as you can find there is a lot of disagreement in the random subject threads on everything from LSD tuning to Suspension Dampening theories...

these guides completely changed my approach on gran turismo, thank you Scaff brilliant job!

[Memnoch83]

Thanks for these !! Actually only signed up here to thank you guys (found out about this forum from iphone app)

Thank you very much for the guide. I had as close to no idea how to tune as you could come and I started my first tune last night. It's really awesome the difference you can make in the car's response. I only tweaked a little bit and a very squirrely car is now very manageable.

[Tintorera]

Thank you so much for these excellent guides Scaff. I enjoy reading the good discussions on brakes etc.

I have a question regarding brake bias tuning in GT5.
By deafult all cars are set up with a brake balance of 5/5 in GT5. When reading your guides that would mean that all cars are originally set up with the same amount on braking force on the front and rear wheels(if I read it right). This would make most cars extremly rear biased, but I don't find them to behave that way with the original settings in the game.

My question is, would a brake balance setting of 5/5 in GT5 mean 50% braking force on the front and 50% braking force on the rear axle or does it mean the "neutral" or factory setting of that particular car with i.e an actual 70/30 brake balance?


Best regards

Titorera, Most cars in GT do have a heavy rear brake bias, this is one reason it is almost impossible to drive a car with the default brake settings with ABS off.

secondly the size of the rear brakes in comparison to that of the front brakes has in my opinion been factored into the equation. So most cars will have some front braking bias for this reason, A perfect example of a car this shows up on is the Nissan Fairlady Z. This car has monster rear brakes and as a result pretty much always suffers from rear wheel lock, even on a setting of 0.

Hey NMRacing and thanks for your answer.

If you read the articles from stop tech, they state that most cars are by factory deafult front biased, for several reasons.
I find it confusing that PD is altering the brake characteristics for most crars from front to rear biased as the original setting in the game.

I agree that when tuning brakes I normally get a much more stable car when setting the brakes to ie. 6/2 rather than the original 5/5.
And I understand the basics of tuning, after reading the brilliant guides(Scaff) and these good discussions in the threads.

It just puzzels me that on this matter the original setting in GT5 would not correspond with the original bias of the same car in the real world.

Now say thank you

i know I'm going to get flamed for this because it'll be posted elsewhere and I'm just too dumb/lazy to look for it, but I gotta ask how come you always have to add 20 mph or so to the 'geared' top speed when you set the gear ratios on the fully adjustable gearbox?

I set for 249 for La Sarthe and the car is maxing out at 232. I figure it can't be aero, cos then I just wouldn't hit the limiter at all.

If you decrease accelerator input, it wil reach a higher top speed.

You'll find the point right before the rev limiter "kicks in" and ease off the throttle so you maintain that RPM. (ie. rev limiter @ 8500RPM keep it steady @ 8400) That should be close to the max speed you set in the gearbox options.
20mph sounds a lot though...??

is the gear what give me a torque or it is the clutch .
I have Impreza AWD 1998cc (2.0L) non turbo with 160 bhp model 2006
I lost the feel of torque at 5500 rpm . I already changed the clutch . but still it's same .

All of the drivetrain upgrades can change the handling properties of the car and the delivery of torque. Flywheel upgrades, carbon drive shafts, the most noticeable for 4WD is Torque Sensing Center Differential. If you want the manual torque distribution feel then go back to Driver Controlled Center Differential or the Standard Center Differential, whichever came with the car.

thanks , maybe I need check the Differential oil .it's Standard Center Differential I didn't change it
I miss for that torque

Hey guys I know Im late but just wanted to say thanks for the guides they helped me out a bunch.

I will have a go at answering the actual question you have asked rather than tell you to ease off the throttle to avoid hitting the limiter. Which, before people get offended is a very good idea because that allows you to run closer ratios and still maintain strong top speed as hitting the limiter drops your speed considerably before the engine kicks in again.
So, the reason why you must set the gear ratios for higher top speed than you actually can reach is quite simple and visually available for you to see. When tuning the transmission look at the ratio graph which shows the spreads between gears, you will notice a horizontal red line across the near-top. This is your engine's rev-limiter. So the answer is, the entire area above this red line in top gear (whatever that may be for each car) is essentially unattainable speed because the engine cannot physically rev fast enough to achieve this speed courtesy of the limiter.
My advice, have a look at the transmission ratio graph (every car is different) and take note of how low down the graph the red-line occurs. Set the top speed irrespective of the red-line to what you want to achieve and look how far along the graph the peak point occurs (the light-coloured boxes help alot). Now set the transmission such that where top-gear meets the limiter line is at the same point along the graph as the peak point of the desired top speed. This will allow you to achieve that speed without any worries.
Hope this helps,
Xerxes.

Ok, now for what I was reading this thread for;
Thanks alot Scaff! These tuning guides are great. Downloaded them a couple of months ago but only really started using them in the last fortnight. Very comprehensive and helpful. Look forward to the GT5 Revision. Cheers.

Thank you very much! I feel like even though I'm a newbie I'll have the upper hand on the sim and other players!

nvm, found the answer a couple of post up...
