Bought a '93 Skyline N1 or something...Tuned it and put VCD on...and now it's bad...I tried LSD, but I got problems, any help?
 
No oversteer...But the under is heavy. I put the ASM Oversteer on 2 so it wouldn't slide out, I put ASM Understeer at 0...And TCS on 2...So I don't know the problem now.

turn off all your ASM and TCS. Also, use your VCD and put more % of power on the rear.(around 20-30% for the front). If that still doesn't help, then buy some suspension kit and reduce the spring rate on the front and raise it on the back. (or maybe...you could do a weight reduction on it too...but that is your choice)
 
I did all three weight reductions, and I refreshed the chassis, I messed with the spring rate too. I made it lower, higher, I messed with the shocks, the Stabs'. Almost everything in suspension, I don't want to put my VCD on, because usually for me, I don't know if this is a proven theory in GT4...Or any where in GT...It decreases me HP. It doesn't say it does, it just feels like it.

Rule of thumb:
Front spring rate is lower then rear, then less understeer.
Same for stablizer bars and shock absorbers.
Front ride height lower then rear = less understeer.
!!!Caution:The next tip MAY be WRONG, so don't think it is right for sure!Caution!!!
:scared: Front Toe: IF it is set to POSITIVE 1 or more, understeer = less... :scared:
I have tried this on my integra type-R in GT3 and it did reduce understeer ALOT...But this is GT4 so it is different...Maybe it will help or maybe not... :scared: :scared: :scared:
 
I'm gonna try that...Hope fully that would work...Except you're wrong on the toe...Increasing Front Toe will INCREASE Steering. So I guess it means that you can turn in faster or something. But I've seen no difference, and settings rear toe negative, will let you have greater control if you spin out I think, it works in drifting...
 
Firstly, everyone says to turn off ASM but if, for some reason, you can't dial out any problems and feel it's your only option, then you should note that you have your settings the wrong way around.. if you want less push adjust the ASM Under settings, not Over..

Though, I don't have to remind you that suspension setting is your best option..

Second, have you bought the Increase Rigidity option (rollcage)? I found this to be the BEST upgrade for increasing oversteer and decreasing understeer on my R32 GTR's..

Another tip would be to use a softer compound tyre up front compared to the rears. Though, you might have tyre wear problems in longer races unless you fine tune your suspension settings. Be careful with Toe settings as they increase tyre wear problems.

By doing these upgrades you'll find that the car will be quite easy to drift on any compound tyre (Normal or Sport. Remember to have a softer compound up front) and that IS what you want isn't it?? lol!..

You may even find that you don't have to make many suspension changes unless you want to fine tune it for particular tracks..

My last piece of advice would be to TUNE THE LSD which, in my opinion, is the most effective tuning aspect of GT4. See my sig for LSD tuning..

So, after I've "standardised" my suspension and transmission I fine tune the LSD BEFORE I start fine tuning the suspension.. THEN back to the LSD.. lol
 
Okay, about the echo's...What are you talking about? No, I don't have the roll cage installed. I tuned my LSD a couple of times, I did as is...for front I tried 10-20-5, 15-17-13, 19-23-13- 10-20-8. None of that worked. For the rear, I tried, 30-50-20, 20-60-10, 15-40-10, 15-25-10. As again, it didn't work. I took the VCD off because I find no help in it. So I don't know, I might dump my car and work with something else. BTW I have about 750hp.

I interpret this as huge understeer, and no oversteer.. am I right?
Try driving on N tires for a while.. S tires will feel like superglue after a while, and all your worries will be gone.

My best tuning tip though, would be to do the opposite of what KiwiBoy mentioned... except the ride height bit ;) It seems to me like stiff=grip and soft=loose in the world of GT4 suspension.. at least on N/S tires. Also: aids need to be off if you want to tune your car.. or else the ASM/TCS will compensate and blur out the changes you made to your setup. TCS is never necessary on 4WD cars.

I'd go for the stock LSD or a 10/40/10 rear and 5/5/5 front setup, springs at 10F 7R, dampers at 8F 4R, stabs to 3/1 and front camber up to 3+. This is my "default" understeer cure package and it usually shows some promise out of the box.

If nothing else seems to work, maybe you're just entering the corners way too fast. Try my tip with the N tires above.. and go drift more ;) After a while of that, you'll get a lot less understeer trouble... Another thing when turning 4WDs is keep the throttle input low/controlled. The more you floor it and the more you yank the wheel, the straighter the car will go, but I'll assume you already know that from all the threads around here ;)

IF you meant that the car was oversteering, then I'm with KiwiBoy on the suspension.. but the N tires/drift training still works marvels.

BTW: I think that 750HP is way too much for that car and still expect it to handle OK. Try detuning to about 600 max and soften it up a bit.
 
When does it understeer? Entry, exit, slow corners, fast corners, all the time?
Turn off all driving aids, put on N2s, take out the turbo kit and LSD and then find a basic suspension setup you like. Then add power and the LSD and tweak the power on/off response. The put on grippy tires and go back to the suspension.
FWIW, I've A-speced the EL Capitan enduro with my R33 LM Ed. on S1s in 430 PS tune and had a ball. Maxed out (755 PS) I've used it for the Nürburgring 24h (shared with B-spec Bob though) and find it still quite enjoyable to drive in that form. If nothing helps, remember too much speed into a turn will make any car understeer, and with 750hp that happens quite easily..
 
just lift off the trottle, tap brakes as you turn it.. it does the trick for me, even with more powerful cars. My GT-R32 had R3 tyres and way over 700 bhp, and it loved to go sideways.. unfortunately, i don't have settings to give, sold that car because it did wear out so badly during endurances. :ouch: :grumpy:
 
@Ske
I've tried your settings, and what I got was plenty of stationary understeer combined with a rather nervous rear end... Guess our driving styles aren't exactly compatible (DS2 or DFP?).
Anyhow here's what I use:
springs 9f/10r
ride height 120/120
dampers bound 6f/7r
dampers rebound 8/8
camber 2.5f/1r
toe 0/0
stab. 2f/4r

downforce 30f/28r

LSD initial 7f/8r
LSD acc 20f/25r
LSD dec 10f/35r

VCD Standard

it's a 96' Skyline GT-R VSpec LM Limited, stage 3 weight reduction, cage
 
@Verbal

Well, I gotta admit I didn't test those settings, and grip settings may not be what I do most of.. They're just what I normally start with to make an understeering car more driveable. But then again, I'm used to drifting so a nervous rear end is how I like it ;) I use a DF (not pro) btw.... And I always found that a stiffer rear made the car even tighter and harder to turn. A '96 VSpec LM would be a pretty different beast than the OP's though.. wasn't '93 Skyline an R32?

Also, your LSD settings seem a bit weird to me.. looks like they'll make the car very hard to turn while decelerating.
 
Yep I'm with you, lower spring rates in the rear than up front, but a softer sway up front. But keeping the power down is a must or the front end washes out.

You think? I wouldn't have expected the R32 to be all that different...

That would be more affected by brake balance and damper settings, and you're supposed do be done with decelerating on turn in anyway ;)
That setting keeps the back in check on power off, but it's not very hard to turn at all. You're right, this is no drift setup (though you can provoke it to do nice four wheel drifts), but very nice for several hours of sub 7' laps on the ring...

Well, I tend to trail brake and generally brake late for/into turns, so I like my cars to be a little more agile.. This would be a classic matter of preference and driving style, though. So, I guess I shouldn't argue more without testing the actual car :p

And yes, the R33 is supposedly very different from the R32 handling-wise. According to the GT4 "pros" even the various spec models in the same range has pretty varying specs, but not like that would matter much to general settings ranges for the general public...

:dunce:

Edit: A Nürburgring setup you say? I won't argue with you then.. that's the one track where I like tight cars. Trailbraking is seriously dangerous there, and some of those dips, bumps and offcamber turns demand some serious poise.. especially the flat out dip before Adenauer Forst or something (forgot the name). My settings are good for "modern" race tracks (ie most tracks in the game), but at the ring it'll be a pretty hairy ride ;) I don't really set up cars for ring driving.. I tend to switch to stock ride when I decide to visit it.

I find that the ring demands a totally different setup than the other, flatter tracks. Ring setups may work decently on Deep Forest though.
 
My N1 R32 with a stock diff, no vcd, very minor suspension tweaking and R5 tires F and R, is really neutral. Honestly, I don't think it's possible to make any of the AWD vehicles in this game handle 'great'. Especially if you are using S tires..

You have to be willing to compromise.
 
Well, I think everything handles great on S and R tires... I don't really use R's unless I absolutely need it to win a race though.. it feels like the car's on rails and you cant toss and slide it around. I guess that's what happens when you're sideways on N1s 90% of your GT time... ;)

I think the R34s seem pretty good stock on N and S tires, though they're pretty loose and dangerous to drive on the ring (at least the v-spec nür for some reason). The Impreza 22B is also great on stock suspension and S tires.. it's pretty tossable, which suits me.
 
When you are competing against other people for the best time, and when you have 700+ hp, anything less than R-compound tires is an instant loss.

Sure a stock Skyline handles ok with N-S tires. But stock is boring. :)

sorry for the OT

The R34 M-Spec Nür with N2s is quite a fun car on the Ring, check my gallery and you'll see what I mean ;)
 
Well, I tried all your guys idea's to tune my Skyline, and none of them worked. What a bummer, I did around 400 HP - 700 HP and put racing tires on, and VCD and LSD tuning and crap, and none worked. I'm realy bummed. I sold it though, maybe I could start on a different AWD car...
 
Same, get rid of LSD and VCD....they both screw up your handling. By adding all of that crap, you are overriding the ATTESA system which is the whole reason a Skyline holds the road the way it does. Learn to drive the car, don't just slam the gas and brake. Learn to glide the car around turns like its on rails. Don't push the car within a turn....UNDERSTEER will hit you like a train. AND FOR GOD'S SAKE, DON'T TUNE YOUR CAR ALL THE WAY UP....ITS UNREALISTIC AND DRIVING A CAR LIKE THAT WON'T TEACH YOU THE BASICS OF THE CAR'S HANDLING!!! Start with a near stock car and build your way up modestly. It's never failed me and I can say I've mastered and memorized the driving dynamics of my top 100 FAV. cars in multiple stages of tuning. Now, GT4 is like an arcade game to me...playing it now means perfect laps, almost no loss of grip at any corner, and hardly ever a loss (unless I'm heavily outclassed). Good luck and practice practice practice! :)
