Lancia Delta help

[MockngBrd]

Anyone have any luck dialing in tunes settings for the street Delta?

i tried a number of tweaks but the car still understeers and drives quite... 👎

even putting the torque bias 10/90 doesn't seem to do much, car still seems to suffer from a lot of understeer.

Race tires and 70/30 split front to rear. Big turbo and a 20k transmission helps too. Its a great car once you lighten it a bit.

i'm running race softs and a stage 1 turbo now with a "fully" customizable tranny and fully lightened.

but wldn't increasing torque 70 front increase understeer?

 

[andyt11]

sorry, 70 to the rear, 30 to the front.

I've maxed mine out and lightened as much as posible. The custom tranny is a huge help too.

My next task is to set up the suspension / camber / toe and really get this car nailed. Its a rocket around the nurburgring, that track is so bumpy. Quite good round Edgier Mountain or what ever its called too. You can basically crack the wheels loose and drift the hairpins!

was doing some tweaking last night. I can't get the wheels loose but managed to at least make the car drive a little bit nicer and not push wide everytime.

Was doing some time trials@Tsukuba and managed a 1.00.9xx

will post some settings later.

Ill try around with it to, i only have done most the basics parts (except for a big turbo) but its a shame such a nice car handles poorly stock.

First and foremost, transferring all torque to the rear tires do not necessarily mean it'll generate oversteer, do not forget that this is an AWD - meaning the front tires actually help to maintain traction and pull the car through and out of corners. So I suggest reverting to 30/70 torque split, and adjust the LSD settings instead.

If you find that the car still understeers, then decrease the acceleration sensitivity on both ends (though the front should be 30-40% less sensitive than the rear). Initial torque can therefore be increased slightly and should remain even on both ends. On the other hand, braking sensitivity should be increased by equal amounts, thus more stability on braking. If you find corner entry difficult, then reduce front braking sensitivity slightly.

NOTE: Its better to start from aerodynamics before tuning the rig, as it doesn't have any detrimental affects besides decreased or increased top speed. Similarly, the LSD should be taken into account prior to suspension and alignment adjustments.

Try increasing the stiffness of the rear suspension. LSD should all be set to 5 (maybe 15ish on the rear accel) and I usually go with 15/85 on the center diff.

Also, toe out on the front ~.4 and if necessary toe out on the rear ~.25.

That should help it rotate.

some more testing, couldn't totally iron out the understeer but managed to get a sub 1min time (0.59.4xx) on Tsukuba with these settings.

These are by no means the optimum but the result of just fumbling about:
LSD F/R
5/5
12/5
11/11

Torque bia
30/70

Suspension F/R
Ride height -15/-15
spring rate 5.9/6.4
dampers (ext) 4/4
dampers (comp) 4/4
ARB 3/6

wheel alignment F/R
Camber 2.0/0
Toe angle 0.25/0.05

brake balance
5/7

let me know if it sucks

Not having much luck with this one. Tried the various tips on the thread but the main problem i'm having is understeer during the corner exit. As I advance the throttle exit the corner the car just doesn't want to turn. Any ideas on how to fix this?

It is a shame because its not like that in real life. I'm sure someone will correct me but at one point it was the fastest point to point production car available. (where I lived anyway)

I've been using it in GT5 a lot, i'd say its the car I've logged the most miles in. It's now completely maxed out and I think the best improvements were dropping some weight and putting racing tires on. Other than that I usually try to run slightly harder suspension on the front than the rear. Now I'm just playing with suspension settings to further dial it in but I'm enjoying it as it is.

I'd say its more suited to tracks like the nurburg ring too. Bumpy fast and twisty tracks. I've never had much luck on a flat smooth race track, there are better cars out there for that.

If anyone comes up with a good suspension setup I'd love to try it.

Once version 2.0 of my tuning app is available you'll have the perfect tune at your finger tips, e.g. No more understeer!

This works like a charm!

You need to bump your LSD numbers up, you're guaranteed understeer running it like that. Try the LSD on default and see if it's improved, it must be - then just keep going.
If not then your suspension settings must be wrong.
