Forza 3 tuning help?
Discussion
Hi all
Im just going through the 'Event List' and i always try and use a car that i like rather than a car that is the PI that i need. So inevitably i have to tune that car somewhat, currently in a S650-ish Porsche 944.
The only problem of course is that when i race againt cars that were a high PI to begin with the always handle much better than me.
I use that Forza 3 tuning calculator and that does an ok job but what i need is some general advice on how to add overseteer, reduce understeer, turn in, etc. and other basic handling characteristics I dont want anybodys secrets, just general tips on how to set up a car.
All the storefront tunes seem to be Drift this and Drift that. Not my cuppa, well not until i become less rubbish at it.
Cheers

Oversteer / Understeer can be countered by reducing spring strength and roll bar for the 'end' thats causing the problem. Thats the simplest way. If you want a decent S class you are going to need to go away from the 944, what are you after, I'll see what I have and try and send you a tune to see it.

oversteer/understeer can also be controlled by toe on the wheels.
For example, on almost every single car I tune, I always add some toe out to the front wheels to aid turn in.
Also, getting the diff setup properly can make a huge difference to how a car enters and exits a corner.
This is exactly the kind of hint i need, cheer. What do you mean when you say setting up dif. I dont really understand diffs apart from the very basics.For example, on almost every single car I tune, I always add some toe out to the front wheels to aid turn in.

Also the ingame auto upgrade is normally good enough to beat the opposition.
Bear in mind your driving skills may also need to be upgraded, the tune cant do everything.
I have no problem beating the oppo, i just wanted some help to make the cars a bit easier to drive.Bear in mind your driving skills may also need to be upgraded, the tune cant do everything.
Basically, as you only have two settings.
Test the car, and if when exiting the corner with power the rear wheels spin up too much and you get big oversteer, you can turn down the accel setting of the diff.
I'm not 100% sure on the decel setting yet, I never usually fiddle with it much.
Its to do with slowing down and turning, I think its if you find your getting lift off oversteer or oversteering with no throttle, you can decrease the decel setting to try and get rid of it.
With the accel setting, don't drop it too far down, else you will find that you lose acceleration. If you have a play with the diff at 75%, drive the car, then set it down to 25%, drive it again, you should be able to feel the effect its having and you'll hopefully understand the setting more and be able to tweak it to your driving style.

What setup have you got?
I just tuned one up to R3 723 so there's a bit of scope for doing things differently.
I always start with the Colin Chapman maxim "Add Lightness". Do all the lightening you can - The main one, but also the flywheel, the propshaft and the wheels. Lots of other bits (suspension, brakes etc.) are lighter than the standard ones too. After that, get better grip - Widest tyres possible, then slicks. Don't bother going bigger with the wheels as it just makes it heavier.
If you do all of the non-engine mods (with the exception of the front wing) you should get to an A528, so add the race cams and exhaust to get back to an A650, which will be much easier to drive.
-edit-
Actually sod all of that, just make sure you have AWD and the front wing installed (AWD always adds a bit of understeer) and you'll be fine.

setup wise, i tend add a few clicks of camber, toe out, soften the springs and damping and open up the diff a little bit. then work from there. parts wise, it depends on the car. some times a race clutch will take 0.15s off a gearchange, sometimes only 0.01. light is good for control definitely too. I tend to go up in tyre compound before widening, as I prefer the feel of narrow tyres!
