Ok, so got this problem, no idea how to rectify it.

No matter how little I accelerate around the corner, the tires spin and I near on lose control.

Can anybody give me some suggestions on how to fix it?

Current car I'm using is a Viper SRT10 ACR ‘08 tuned to Praianos guide. (But HP is about 970)


Cheers
 
Well if you have 970hp, sports hards perhaps and a controller then it can be quite tricky. Are you feathering the throttle or mashing it and just expecting 970hp to go through road tyres with no problems?

This. With 970hp and countless torques from
the Viper, you'll spin the rear wheels with any tyres if you don't use some throttle control, I don't think it's entirely the tune that's the problem
here. :p

Sorry, they're racing hards.

Not exactly mashing it. I was doing it bit by bit.

Basically, everything bought (Except weight reduction) and all settings followed per this guide.

Initial Torque = Front 0 Rear 52
Acceleration Sensitivity = Front 0 Rear 32
Braking Sensitivity = Front 0 Rear 37

Suspension
Fully Customizable Kit
Ride Height = Front -20 Rear -20
Spring Rate = Front 16.5 Rear 13.5
Dampers (EXT) = Front 6 Rear 6
Dampers (Comp) = Front 2 Rear 2
Anti-Roll Bars = Front 2 Rear 4
Camber Angle = Front 3.5 Rear 2.5
Toe Angle = Front +0.10 Rear -0.04
 
Your LSD seems very, very aggressive in general, but especially so for a car that packs as much torque as the Viper. Try something way calmer, such as
Initial Torque - 8
Acceleration Sensitivity -14
Braking Sensitivity - 9

Sorry but this don't have anything to see with my tune.
My tune is this one, it work good after 2.09, just put ride height 00/00

Sorry, I've used your guides so many times for so many cars, and they're fantastic! I got a little confused, I couldn't find your guide for the viper, so I used a different guide. I love your guides! :D I've been tinkering with settings for a while, and they never seem to get where I want them, yet when I used your guides, the cars drove unbelievably! :)

That looks about right...lol:tup: If you want more in depth knowledge as to how the LSD works, as you can't tune a car without tuning that, look here:

Hmm. Thanks. :)
I've given up trying to tune my own cars. For now. I've been using guides already available. But yes, I will be doing some reading. Thanks! :)

Im confused with lsd tuning, how would a lower lsd help since there is oversteer?

Because, the lower the Accel setting, the less power sent to the wheels, thus eliminating wheel spin. The higher the setting, the more power, with more chances of wheel spin. Sorry, not the most technical of definitions, but you get the idea...I hope. Read Hami's LSD guide, its a wealth of information.
 
Ok, so new problem :D

Trying to do the 24H and failing spectacularly!

Using multiple cars.

So far I've used the Toyota 7 Race car using praianos guide. Gave me excellent control over the car, but it's not fast enough. (Tops out at 200mph) I came in at 6th

I tried the Escudo dirt trial car. All I have to say...Wow! It's an awesome car. It's handling is incredible (When using Praianos tune) It got me 2nd place, but still, same problem. Tops out at 200mph.

Now, I'm using the C60 Judd Race car. Fantastic speed, with reasonable control. Even being extremely careful with the throttling, it always loses traction upon acceleration. No matter if it's around a corner, or on a straight. With this however, I've moved the ballast to +50 and added 88kgs (45/55) to put more pressure on the rear wheels. However it gives me fairly poor control and traction is terrible.

I haven't been able to use Praianos guide, because I can't find one for this particular car, instead, I used:

Every mod bought. Racing hard tires.

Suspension:
Ride Height: -4 / -20
Spring Rate: 12.1 / 10.7
Extension: 10 / 10
Compression: 7 / 6
Anti-roll: 4 / 4
Camber: -1.5 / -1.8
Toe: 0.04 / 0.10

Differential: 14, 37, 22

Aerodynamics: 60 / 80

Brakes: 7 / 7

Ballast: --

Engine: 100%

Transmission: 236 mph
4.500
3.000
2.200
1.672
1.280
1.000
2.550

Tires: Racing Hard


I'm trying desperately to complete this track. It's on of the seasonal events, and last race in the set.

Any advice?

Cheers

Use the Bentley race car. Easy fast, no problem of traction.... I have a good fast easy tune for it.👍

Lower the LSD so it won't be o tail happy

How do you get the Bentley?

I don't think I've seen it in the car dealerships.

Don't suppose I could tempt you to do a tune guide for the C60 Judd Racecar? :)

This car (Pescarolo) is difficult to tune and to drive. You can win a bentley at the 500PP brithish seasonal. You can make it easy with my lotus elise 111R 500PP comfort soft .
 
Lower LSD = oversteer, but less power sent to the wheel
Higher LSD = understeer, more power sent to the wheel
Shouldn't oversteer and understeer be flipped?

Be more specific, there are 3 LSD settings.

High Initial, usually means more understeer, better forward bite.
Lower Initial, usually means more agility, slower acceleration.

High Accel, usually means more outside tire spin
Lower Accel, usually means more inside tire spin

Higher DeAccel, usually means more understeer on corner entry/center coasting
Lower DeAccel, usually means better agility, but less stability, potential oversteer on entry.

*Don't care what the game says, don't care what real life says, don't know why the game says what it says. The above is simply what I've found to be true and accurate through my testing, tuning and racing. The who, where or why is absolutely irrelevant in my opinion.

Accelerating out a corner:
TOO LOW LSD ACCEL = power go to the wheel with less weight on it = Inside wheel(s).
It's safer, don't cause oversteer but you don't use all the power available, it's wasted and transformed in the inside wheel spin.

TOO HIGH LSD ACCEL = torque transferred to the wheel with more weight on it = external wheel(s)
The ext wheel spinning loose grip and cause oversteer.

You need to match the right amount of LSD accel to let the car or:
-Agressive (a bit + LSD value than the sweet point)
-Safe (a bit - LSD value than the sweet point)

Braking in a corner:
LOW LSD DECELL = car more loose and oversteer tendency
HIGH LSD DECELL = car more planted and understeer tendency.

The initial LSD setting is just a level adjustment that will increase or decrease the others 2 settings proportionally.

This is how i see this LSD :ouch: settings.

Hope i express me clearly.

EDIT: Adrenaline my friend, this is syncro of syncro. hahaha
 
That race is impossible! I can't do it!

Even with your guide, I can't keep the 111R on the road. It fish tails constantly! :(
 
Finally got the Viper how I like it! :)

Little bit of tweaking, No longer loses traction, steering is great. It's a little slow still :D So I think I'll have to see what I can do with the transmission.

Thanks everybody for your help!

It's greatly appreciated! :)

Wrong, a LSD does only distribute the given amount of power (if we ignore the loss).

First it's an ACR, then a C60 and now a 111r? What's next? duh...

Sorry. I thought this forum was to help people....My mistake.
 
Hey try LSD setting of 5/5/10 on any high power car and watch rear tires will both stop spinning up around a turn..

Thats what I meant. No need to correct me as I'm fully aware of what the LSD does and how to tune it. I'm just not the best at explaining things.
