Hi folks,

I have a setup for my SV that I'm pretty satisfied with. I tried the other tunings on this forum for this car but none really suited my driving style. I'm sharing my tunings for possible feedback whether it works for you or not, or whether it needs to be finely tuned even further.

The car has everything imaginable installed from the tuning shop including soft racing tires. The only thing I didn't install was the aero kit of any kind from the car maintenance (I find them to be ugly with the exception of 'front', but I haven't bought it yet).

1st optional tuning:
Transmission top speed: 242

LSD
Initial: 20/20
Accel: 30/30
Braking: 60/60

Torque: 35/65

Suspension
Height: -10/-10
Spring: 10.5/10.5
Dampers Ext: 6/6
Dampers Comp: 6/6
Anti-Roll: 5/5
Camber: 2.2/1.8
Toe: -0.16/-0.03
Braking: 6/5



2nd optional tuning:
Transmission top speed: 242

LSD
Initial: 10/10
Accel: 30/30
Braking: 30/30

Torque: 20/80

Suspension
Height: -13/-13
Spring: 14.0/14.0
Dampers Ext: 4/3
Dampers Comp: 4/3
Anti-Roll: 4/3
Camber: 2.4/2.0
Toe: -0.10/0.02
Braking: 6/5

Its a good tune fella, ive knocked about 600ths of a second of my TGTT laptime, but i know it can go faster, i just cant seem to get a lap to stick, its that damn 1st corner lol
 
Very stable tune, however, for my driving style I couldn't handle all that understeer. Below is some changes I made based on your tune that worked best for me. Also regardless of understeer I felt that 9.5 is to low for the spring rate on racing soft tires.

Downforce: 30

Transmission: same

LSD (This is mostly what I changed to help that understeer issue)
Initial Tq: 10/10
Accel. Sens.: 18/18
Braking Sens.: 25/25

F/R Tq Split: Same

Suspension
Ride Ht.: -10/-9
Spring Rate: 13.5/14
Dampers (Ext.): 7/7
Dampers (Cmp): 5/6
Anti-Roll: Same

Camber: 2/1.8
Toe Angle: Same

Braking: Same

The changes to LSD make the car MUCH less prone to understeer (which I can't stand), but I still can't quite get rid of it in high speed (140+ mph) cornering.. :(

The changes I made to the suspension make the car IMHO a lot more maneuverable and agile in low/medium speed S's (specifically the ones in Suzuka) and chicanes.

So ya, let me know what you think.
 
Do you understeer when entering a corner or when exiting a corner? If it's entering a corner, you can turn down the braking sensitivity. If it's exiting a corner, you can turn down the accel sensitivity. The problem I find with this car in particular is that you have to pretty much set up the car either for purely high speed tracks or for purely low/mid speed tracks. It's not a very versatile car where one tuning can work for the majority of tracks.

Are you using a driving wheel? I'm not entirely sure how oversteer/understeer works on the DS3 controller since I've been using my DFGT since day 1. I don't find it to understeer too much with the wheel, but the Murcielago SV in general isn't very stable when braking into a corner.

I'll give your adjustments a shot. I should have mentioned that I generally use spring rates of 10.5/10.5 on most tracks, 9.5/9.5 on bumpier tracks. Glad that there are other owners of this beastly car!
 
Ya I love the car, I use Logitech G25 wheel and i found that it understeered a lot entering and exiting a corner. After my adjustments it no longer understeers at all entering and only exiting on high speed as I mentioned.

I definitely agree with you on it not being versatile, I usually tune most of my cars on Suzuka full because I find it has a good mix of high speed and low speed cornering.

Hopefully some more Lambo fans can join in!
 
When you used my setup, did you originally have a problem during corner entry, corner exit, or both?

I just tried your setup on four different tracks. I felt the car was way too unstable during braking and during corners, even if it improved corner exit. I felt my front tires were giving out way too much/too often. For the LSD, maybe turn down initial torque or accel sensitivity, but keep the braking sensitivity the same (from my settings). I feel the Murcielago SV's braking overall is way too unstable whether it's a straight line brake or corner brake.

I also feel that overall the stiffer spring rate in your setup provides less grip to the road. Maybe it's dependent on driving style. Thanks for the feedback btw. This car is a difficult beast to tame! Regardless I made some minor updates to my original post reflecting some of your findings as well as some of mine on different tracks. I dropped the LSD accel sensitivity, increased anti-roll, increased spring rate, and changed the rear toe angle.

I really don't have anything to add to this discussion, with the exception that this is my favorite car that I've purchased, and I love you guys for this thread.

I'm an admitted amateur at tuning, but I know it's value so big 👍 for your guys' homework. I really don't have the spare time to test so this really means alot to me.

Keep up the good work, guys! :cheers:
 
So I played with the tuning and decided to take a completely different approach than my original post. This is the 2nd optional tuning that I added to the original post.

Transmission top speed: 242

LSD
Initial: 10/10
Accel: 30/30
Braking: 30/30

Torque: 20/80

Suspension
Height: -13/-13
Spring: 14.0/14.0
Dampers Ext: 4/3
Dampers Comp: 4/3
Anti-Roll: 4/3
Camber: 2.4/2.0
Toe: -0.10/0.02
Braking: 6/5

Let me know what you guys think.

Why would you guys bring the top speed down to 242. That's way too slow for some races. Or is this a "city" setup?
Click to expand...

You generally want the car to reach its max speed right below the rev limiter on the last gear. Setting the top speed any higher doesn't necessarily mean the car can go faster. This top speed number is to set the gears, not the engine power which is pretty much predetermined by a variety of other things including horsepower, weight, etc. It's a balance between top speed versus acceleration. You accelerate faster when your top speed is lower. You accelerate slower when your top speed is higher.
 
sorry I haven't ben able to contribute lately, I've got final exams in school so I have to hold off playing GT5 which is a pain. Thanks for your comments johan, its weird about the lsd breaking settings, I know it's a mid engine car so I expected breaking to be extremely unstable, but it never became that way for me, although I always try to break in straight lines with mid engine cars. Did you have ABS to 1?
 
The amount of understeer is a little much for me as well. I'll have to tweek it a bit to see if I can make it more stable. I do enjoy a lot of oversteer in this car - it's crazy!

I've been using ur original setup with success. I'll have to try your new setup. Did you run faster times with the new setup?
Click to expand...

The new setup has a little less understeer. I personally got a faster lap time with my 2nd setup but it really depends on your driving style. Pick a track that's relatively smooth/even and has twists/turns with some straights. Try each tuning to see which you prefer with your driving style. From now on each time I post a tuning for any car, I'm going to provide two different tunings and let you guys pick which you prefer. There are no hard set rules as long as they all work together in the end.

And always remember, drop your spring rates a few clicks and raise your ride height a few clicks whenever you take any car on a bumpy track.
 
Hey guys.
First, Thanks for this great thread !

I Got my Murcielago SV and tried the latest jjohan35's setup, but I'm struggling with oversteer, I changed the LSD configurations and nothing worked :indiff:

I bought the Chassis Reinforcement on Tuning shop and it helped a little , but the oversteer at the end of the corners still persists.

Any Suggestions?
I'm a novice on GT, but I used to make some modifications on GT3 (even if not worked lol) :gtpflag:

And.. sorry for my bad English:indiff:

Try the first optional setup. Did you max out the mods? And did you buy soft racing tires?

This one is great mate!

Great job!
 
I love the settings and the small differences in detail.

One thing is left, braking on the end of the starting grid on Nürburgring GP is feeling me sitting on a carusell, turning round and round and landing in or near the sand.

Over and Understeer is no problem with these settings..but..

Best Regards

Jochen

This is a problem with many mid-engine cars you usually need to break in straight lines to avoid spinning out. You can eliminate this mostly with tuning however it will increase the understeer of the car dramitically. I personally prefer to live with breaking in straight lines instead of lots of understeer, but if you want to try the first setup posted then you can see if you don't mind the understeer.

Excelent work, thanks for sharing it!

Just one note: 242 miles (I guess you are using miles) are 390 km/hour for some of us...

Where can I change Downforce???
 
thank you for the tuner settings! I was having a hell of a time with this car! I was at the point where i was just gonna sell it and buy something else! but after these settings I can actually drive it and win!
