I’ve been using forza tune 6 and my lite knowledge of car tuning to tune my own cars lately, But I have a few questions and if someone could help clear them up i;d be so thankful. First off, is having 2.0 front and rear camber excessive (tyre wear especially) also could caster and camber be causing slight midturn oversteer? - ill lower ARB and suspension but certain ferraris will still slide all over the place, especially on off camber turns. Next: Where is a good base tune for aero? i Usually do three quarters to full on grip tunes and then a little before that with my all around tunes and drop it at a quarter with speed tunes. Lastly, are there ever cases where ARB in the back should be higher then in the front (im talking RWD since thats the main type i drive)
thanks for your help!!
Dont have the 6, but tried 5 and only thing I ended up using it for was weightdistr. If car is stable I would use laptimes to adjust camber. Camber is not the first you adjust but it can be used to correct over/understeer, yes. Tires will wear faster with more negative camber, and Acceleration and braking will suffer the more negative camber you use. I believe its normal to do full aero on griptunes. For ARB you stiffen rear to get less understeer on cornerexit, and yes, in some cases you use stiffer rear than front.
Im sure others can give more input, Im just a novice compared to the very good tuners you can find inhere.
forzatune does not work and it does not give you a better base tune to work from. i wish this wasnt the case and it was a simple as plugging in some #s on a phone app to get a good tune but the truth is tuning apps do not work. it is a shame perpetrated on forza players.
if you want something quick and dirty to tune a car use befuddles 3 minute tune in the forza 5 section. just drop the camber down to -1.5 front and -1.0 rear. or use the flash tune section in the forza 6 tuning section.
For camber I start with -2 front and rear, then go into test drive and look at my tire temps for inner/mid/outer and adjust camber accordingly for the turns. You can start at 0 and work your way more negative as well. Just make sure the tire temps are hitting the same temps in the corners. Try softening your suspension also, too tight and on shorter corners and such can cause a loss of handling and tend to have more oversteer exiting the corners. ARB I adjust according to weight distribution, if its greater than 50% the front should be less than the rear, 50% should be about the same, and less than 50% should be more in the front than rear. Also check your bump stiffness/ rebound settings, differential settings can cause the oversteer when cornering as well.
The current version of the Forzatune 6 app is the initial release, and unfortunately not as good as it can be,… yet.
The iOS approval process takes time, and so does the play testing and data gathering we need to do prior to making any changes and updates.
More to the point…
-
A softer suspension does seem to promote the grip associated with weight transfer. I am currently experimenting with about 89% spring strength on the stiffness slider.
-
A much softer ratio of ARB values seems to work well in both dry and wet conditions. We may be lowering that balanced value slightly also.
-
The current camber settings are too high, agreed.
Oddly the camber calcs from Forzatune 4 seem to be back in effect. Experiment with values front and rear between -2.0~-.8. Just check for even heating and/or adjust as needed go feel/response.
Also keep in mind that caster settings will affect camber dynamically thru the steering angles.
Steering difficulty/assist setting will also play a role here. -
If or when we see Ruf or Porsche in FM6 you may run into a case where a firmer rear ARB will be beneficial to the tune. Essentially, a rear weight biased RWD chassis could benefit from a stiffer rear bar depending on the tune and driver.
-
Aero tuning depends a lot on the intended build function. At a basic level just adjust it for top speed or grip.
The real fun for me is finding the right ratio of front to rear downforce, but I typically stay between 1:2 and 2:3, except for specifically custom builds.
Hope that helps.
I don’t use the app but -2.0 isn’t excessive for a race car. Most street/weekend warrior cars run -2.0-3.0 all day every day
Unfortunately Forza models very generic and unrealistic unequal length control arm type suspension for essentially every adjustable suspension.
Realism is not as close as it could be.
In FM5 the camber values were useful in the -2.0 or more area, but for FM6, like FM4, they seem to have dropped back into the -1.x range.
Especially in auto-x, and specialized time attack cars desirable camber values can exceed -3.0 IRL,… agreed.
In this game I run -2.0F -1.5R
