Forza 5 - Jelly Cars, Boneshakers and general mucking about

When tuning turns deliberately bad....

Hopefully we'll have some form of in-game tuning soon, at the moment you have to edit files by hand.

I was forgetting about TCSE , the Torc Car Setup Editor....
http://community.speed-dreams.org/viewtopic.php?f=3&t=306

This gives you a graphical way to tweak the cars, just can't do it in-game yet. I suspect that the in-game stuff won't happen till we move to a new menu system as the current one is very painful to work with.

What settings should we make available to change?
    Brake Bias
    Alignment (Toe, Chamber, Caster)
    Suspension
    ...

Hello Simon it is cool to raise the topic of in-game setup edition. It is a must in race car sims today. I think it would be cool to have a default setup wich can't be edited and then have the possibility to create/import/install setups wich were created by users without limits. That way one could have one or more setups for each tracks (race, qualifying, rain or dry...). So far I haven't seen diferent types of tyres in speed dreams but it would also add possibility and realism to this high potential projet ;)

Well to be honest I would think of everything that can be modified in reality. Just thinking of these options:

Suspension:
- Ride height (rear/front)
- Spring stifness (rear/front)
- Anti roll bars (rear/front)
-Toe (rear/front)
- Camber (rear/front)
- Damper compression (rear/front)
- Damper rebound (rear/front)
- Rebound velocity (rear/front)

Brakes:
- Braking bias (rear/front)
- ABS influence (rear/front) (depending from speed)

Engine:
- Restrictor system
- Maximum revs (for endurance and reliability)
- Turbo pressure
- Engine map (for fuel consumption)

Gearbox:
- Editable ratio for each gear

Differential:
- Limited slip dif maximum values
- Traction control influence
- Power distribution (rear/front) (for 4WD vehicles only)

Tyres:
-Type (hard,soft, medium...) (rear/front)
- Tyre pressures (rear/front) (left/right for ovals)

Aerodynamics:
- Wing angles (rear/front)
- Winglets angle
- Brake cooling (rear/front)
- Engine cooling (rear/front)
- Air brake angle

That is all I can think of for the moment. I don't know, as a non programmer, but I am not sure the current setup system is the most flexible to have many different setups. I might be wrong, but I fear there might be a risk to break backward compatibility there so that setup aspect deserves a lot of attention.

Have a nice evening

That's a big long list! I don't fancy coding that menu... but most of those are already handled by the sim engine. So if you wanted to trim these you could. I think you need to copy the installed car's XML into your '.speed-dreams-2' folder (can someone confirm exactly where?) and then tweak away.

The way the parameters work is that various files are loading in sequence and the values/ranges are 'merged' to end up with a final value to use.

When in the garage menu I would think that the most sensible approach is to have the user work on the current car, and have the ability to save settings off to a 'backup' on disk. The for a particular race, the user can select to reload a 'backup' setting or restore to default.

The tire selection is interesting as a future feature. At present there are parameters for tires, for example:
http://sourceforge.net/apps/trac/speed-dreams/browser/trunk/data/cars/models/sc-boxer-96/sc-boxer-96.xml#L368

Perhaps we can pre-define some parameters to model road/slicks/wet-weather tires to be easily imported during tuning.

Tuning by adding files in the user config directory does not work properly. I've entered a bug here:

I found this video of an rfactor mod for the NSX very interesting. Lots of ideas of the scope we should look for when providing some tunability.
