TT No. 50 - Lotus 480PP & 400PP

Its the position of your weight. Front vs rear weight position.

i get ya on the ballast right? Anyway im sure i can get into the 58's i can get about 2 car lengths a head of my ghost but then muck it up on the last few corners blah :ouch:
 
Been using Stotty's tune, but I'm just left hanging at just below 1.26.. got a 1.25:801, but I want mooooore !!! *lol*

Can't get in to hit the apexes properly, coz of my adapted driving style IRL (Club Rally) which was to rely a lot on using engine braking to decelerate just before turning in at sharp corners.. and I just can't shake that habit, so I keep understeering..

Any tips on improving that understeer? I've upped my TCS to 6 from the standard 5 to reduce the tendency of my tail sliding out when accelerating out of corners and my brakes are set at 9-8, but otherwise I'm in line with Stotty's tune..

And about the brakes.. strengthening them should provide me with more stopping power, but I do not really feel much of a difference.. can anyone explain why?
 
Just ran these. After roughly 20mins on each run with some tuning managed to get 1370th and 1317th. Pretty happy about those results at the moment. Might run again later.

Changing the braking balance does not make the brakes stronger or weaker it only impacts the rate at which you acheive the full braking strength. Higher number mean that you go from nothing to full braking faster. Someone did a really good write up on the effect of changing the braking balance in these forums but cant remember who. IMHO your brake settings are not helping you and neither is upping your TC which I think you may be using to try and counter the ill effects of your braking balance and braking style.

I suspect one of the reasons you maybe suffering understeer is that you are losing traction becuase of the fierceness of your braking and becuase of your style you may be braking way too late and are still trying to slow down as you start your turn in hence the understeer. Try lowering the braking balance to 3-2 and practice braking earlier so that you are not braking as you start your turn in.

You should try to reduce your TC settings as that will not help you get a fast lap time. I'm not saying turn it off all together but try turning it down to 2 or 3 maybe. The car really isn't powerfull enough to warrant TC up at 6.

FYI: TC and Stability control are the two worst options for slowing a car down.

Good luck and I hope the above is of some help to you 👍
 
Thanks Argon.. Will be giving it a go on the earlier braking ans going opposite on my previous settings.. ;)
 
I've tried many things attempting to improve on my 1:24.1 time, so far to no avail. However I agree that upping the TC will not help much as it slows the car too much in corners. I use either TC1 or none at all.
I did find that adding 2nd stage turbo helped a bit although the added weight probably cancels it out.
I will try lowering the brake balance to 3 - 2 though.

You're very welcome , pretty sure it will help as it's the late braking that's causing your understeer and as a result, is making every corner into a much sharper one meaning you are slower through the corner and importantly you can't get the accelerator down becuase you are still negotiating the turn when you should be powering out of the exit.

It's the late exit that I think is causing you to increase the TC to counteract the fact that you are bringing the power on when you are still at too much of an acute angle (still in the turn rather than in the exit phase) and are inducing power oversteer which you're then trying to correct with traction control which is not really the best way to tackle the problem.

Some of the more skilled members on here could explain this a lot better than me but I hope you get the idea that if you can sort your braking then you will be in a much better place to put in faster lap times.

Now if only I could be a little faster too but my problem is just plain lack of skill :D

Well I've been at this for a while now using my tune from the 500pp seasonal, got down to a 1:25.3 & really couldn't better it. So I loaded up stottys tune & just couldn't get on with it, especially the arse up/nose down stance, that said I did keep the box ratios the same & just changed everything else.

Suspension:

-20 -20
10.2. 10.9
6. 7
5. 6
3. 4

Camber: 2.0. 2.0
Toe: 0.00. 0.20


LSD: 10/19/20

Managed a 24:5.6, I'm pretty sure there's still room for improvement, but in my hands only half a sec or so, we shall see. Happy racing.
 
Thanks to CR for the car share. 👍

Still currently 8th @ Suzuka and can see more time to shave off but my spare time has run out, so that's it for me. It's a shame as I had just started to get really good times (.6's) at T1 which is very much needed to compete further.

It was fun while it lasted. 👍

Very good advice, and well written! Wish someone had given me that advice when I was beginning in GT5. I learned a most of those the hard way!

No problem. Glad to see you in the top 10.

As Argon says, from your description, it sounds like your problems are primarily due to how you're braking... too hard, and too late!

If you're using a wheel and pedals, and you're trail braking, you need to reduce the brake pressure as you turn in... the front tyres only have so much grip, and asking them to brake and turn at the same time will just make the car understeer. The adage to remember is the more steering angle you have applied the less brake pressure you can use. Turn the brake bias down, get most of your braking done in a straight line and for the time being, make sure you have at least a short coasting phase that takes you to the apex... you'll find you have much more front end grip whilst coasting. Once you get this to be habitual, you'll get to the stage you can go straight from the rake to the throttle.

This will also have a positive effect on your corner exits too... the less you're understeering at the apex the earlier and harder you'll be able to pick up the throttle on the exits. If the car is understeering at the apex and you try to pick up the throttle you will either get more understeer or you'll get immediate oversteer. It's the same as for entry... the less steering angle you have applied the more throttle you can use.

If you're using a pad you'll find trail braking more difficult, so get more of your braking done in a straight line and use a longer coasting phase.

It will probably feel slower to you as the car won't be sliding about and you won't have to make as may corrections... but your lap times will be faster :)

IMO, my set up has a pretty neutral balance and will take a LOT of throttle on the exits, so if you're getting understeer on the way in and oversteer on the way out you're pushing the front too hard. Forget the exit oversteer as that will take care of itself if you concentrate on getting your line and entry speed right.

Good luck 👍

Once again I thank you guys :)

I try never to do brake-steer, but yes, I brake hard and late, coz that's we do in the small classes of Rally where there's a lot of 90°, 180°, 360° (plus everything in between) and even figure 8's plus slaloms and such fun.. using engine braking (which isn't an option in GT5), left foot braking and especially the hand-anchor !! :) bad habits in track-racing.. hehehe

I have tried for some time now to get used to braking later, but my old habits keep creeping back in at some points and i loose it :) have to change my whole perspective of driving in GT5 and d*mn that's gonna take a while :)

Stotty, yes, your tune-up there is quite amazing, especially in defeating that typical tail-happiness of MR-cars + that hyperclose gearing.. has given me a whole new perspective on the whole tuning experience.. :)
 
I just got a 57.875 out of nowhere! I think I can catch yinato soon :)
 
I have managed 1:23.53 with DS3 without assists except from ABS 1..actually 190
Haven't tried Suzuka yet :)
 
Yea, you must have something wrong as that is a 129 HP car. If you are measuring in BHP, that could be the problem. Not sure how to convert BHP numbers to HP numbers but I do know they are different but the same when converted. Make sense? lol.

Decided to give the Elise a rest and have a go at Suzuka, using Numbnuts tune, although couldn't get anywhere near his gearing for some reason.
Anyway have managed a 59:819 which puts me @ #1537 position, 1:991 secs off the lead.

Can still improve on that but at 115hp and 200kg ballast I'm probably a bit underpowered. I find I have stage 1 Weight reduction and stage 3 Engine tune, which I think rules me out of getting any more hp.

I wanted to ask CargoRat if there is a difference between hp and bhp as I thought that hp (horse power) was just short for bhp (brake horse power).

I looked at the thread offered however it does not show hp and bhp, only hp and kilowatt, or whatever.

Anyway, 1:991 secs off the pace with 115 hp will satisfy me till I try again.

Disregard my comments about converting. There is nothing to convert as I was thinking of something else.(other units of measurements.) If you want to know about BHP and HP, read this.

http://www.differencebetween.net/technology/difference-between-hp-and-bhp/

Sorry for the confusion. Baisically, BHP is a different way of measuring HP.
 
""To summerize, HP is measured with all the accoutrements attached to the engine, to determine its maximum rate and speed. BHP, on the other hand, is more of a theoretical calculation, which is made under lab-controlled conditions, and without having anything attached to the engine.""

Thanks for that CargoRat, learn something everyday. One of my sons gets his V8 SS ute dyno-whatever every now and then, I now know a tad more about what he's talking about.

No problem. Just didn't want to confuse anyone or give any false information. Better to just give a link sometimes.

Hi dude, How are you taking the 1st bend are you breaking straight and strong and the gliding the corner on the apex or lightly breaking and then accelling a bit and breaking before coming out of the hairpin?? Cheers!

If you can get BHP up to 125-127 you`ll have no prob beating your time aswell as getting into 58's
 
what do you members think of a chassis reinforcement on the gsx? positive or negative? and do you make your gears a little bit longer or you made it short as possible?
 
i shorten the gears and adjust the the final gear, thats from learning from members on here,

On another note i just got a 59.056 made 2 notable errors could have been a mid to late 58's lap
 
If you can get BHP up to 125-127 you`ll have no prob beating your time aswell as getting into 58's

I just did a 59:748, puts me at #1392, unfortunately I can't see how I can gain the extra hp from 115 to reach 125-127hp as the car has stage 3 engine tune,

56.4% power and there is nothing left to get rid of, air filters etc, no down force etc.

I can probably get a but lower but probably not into 58's I don't think.
 
I've never shared a car before from someone, not even sure I know how to do it, but if there is someone with one with 125-127 etc hp who is willing to lend it I'll have a go and see if higher hp helps me.
