With stock suspension the CSL is an absolute dream on the 'ring, so it'd be surprising if it wasn't good on semi-racing susp...

yeah, the car is brilliant with the stock internals... and with a full race suspension... but the CSL seems to really not like the semi-race setup.
+ i really wish we weren't using porting and ballancing... the added revs make the engine feel completely different. oh, and the semi-race muffler ontop of the added revs make it sound like an angry honey bee. :/

anyway... i hacked my full-race suspension settings into something useable on the semi-racing:

spring: 9.2 / 9.0
height: 87 / 87
shock: 7 / 6
camber: 2.5 / 0.5

first splits:
44.709
1'18.976
1'47.153
2'37.859
3'15.915
3'42.430
4'32.346
5'14.333
5'35.483
6'17.954

that certain minute barrier is hanging infront of me like a carrot on a stick.
I think its totally possible. especially since i've seen 44'2 in sector one... thats a half second right there. just gotta keep pushing. 👍
 
Wooow Dr W , that T10 Time is a sizzler. ( sure your not self medicating ) ;)

My T10 - 6.31

Any tuning gurus out there with an explanation of the interworking of Springs and Dampers would be appreciated muchly 👍

Im afraid im not sure either Steve on this....I think the stiffer the springs - the stronger the dampers must be set but im not 100% sure.

Well im finding the CSL to be a tricky little customer so far, I originally set out thinking it was understeering and tried to set up as for previous weeks and got my T10 down to about 6'21.9xx.....

However i changed my "B" setting in my tuning screen the exact opposite of my first settings and found the car quicker although didnt make a clean time, the difference was in the back end feeling more planted and the sensation of the rear pushing me round the track was more pronounced, with some fine tuning i think i can improve a few seconds maybe, the CSL seems to like a softer set up as vexd said already, maybe its that the semi race settings are stronger by default than the sports, im finding a lot of understeer this week but one things for sure that its a blindingly quick car, destroys the Skylines time but you always feel like your going to come off at the next corner...........??

Anyway, front settings slightly higher than rear seems to be the way to go, so im off for another hour with the Coupe Sports Lightweight 👍

cheers

I usually do.

Its fast alright, but does it stick?

I lose it thru Flugplatz on 2 out of 3 starts, and then i can lose it anywhere else with a random misplacement of the (insert thottle/brake here as req'd)pedal and absolutely no warning.

Skittish is the best pseudo-english word i can think of to describe it.

The problem lies in the amount of power we are playing with and the weight balance just isnt quite right.

so much for near perfect BMW 50/50 weight distribution, once VEXD has had his hands on it, the handling sux!!

Nevermind, back to the grindstone.

Good luck everyone....

Interesting to compare, the power to weight of the Skyline Week 5 was 317BHP/TON with the CSL coming out at 342BHP/TON, it was about the step up i wanted for week7, im not so sure the power is the problem, its more the set up of that semi race suspension for me, touching the grass is a no no unless you want to see what its like reversing round the circuit, at least i have it able to take a bit of kerb now instead of wanting to lift off for orbit upon the slightest suggestion.....!!

Still no clean lap for me :( Two nights running, only 2 laps complete (and way slow), lots of off road excursions and lord knows what else ... if it's bad, I've done it. Come off before the start line, lost it numerous times on the first corner, not seen T1 too many times. Think I'll give it a break for an evening or two and hope I find my groove later in the week.
 
I can win alot of money again with the dtm races, so I am back in to compete :)
My first clean lap was 6'54.094 at T10

Nice one good to see you here 👍

Im going to have a last attack at this on sunday i think, turned out to be a tricky week but im still deeply in love with this car..... :)

cheers

Dave
 
Oldly enought, i like the M3 standard better then the CLS for some reason... but this car is stunning.

Sadly i really don't have much time to work on laps 'cause of work and gf. But its still a blast! ;)

I still think it would've been more fun with the Esprit : )
 
Dave_George
Hi RedOak, I would prefer you use semi race,using sports suspension would defeat the object here of trying to understand how to set cars up on semi race, with the ultimate goal being to correctly set up race suspension 👍

regards

Dave
Dave,
Respectfully if this is the point I'm going to completely miss it. Unfortunatley, I only have but so much time to put into this...so I slap the parts on, do mostly random adjustments and run for about an hour. I don't have time to run some laps...and adjust...run some more...adjust some more...run even more...you get the picture. Each lap takes too long at least for the amount of time I can devote to this.

I would benefit more from some "hand holding" through the setup process. If the point is to learn to set up a car, it would seem that running the same car week after week would be a better way to teach this. As it is I spend most of the time I have just learning the different handling characteristics of the "car of the week". If we ran the same car I would get to "know" it better and could focus on the setting nuances. It would be helpful for someone with a real touch for setups to guide me through stuff.

Someting like:
Week 1 - Car in Stock Form
Week 2 - Same Car - Add the first level of adjustable parts. Use default settings.
Week 3 - Have a knowlegible tuning person guide us (me) through some settings...one item at a time. This might take be in the format of suggested settings run some laps to get the feel of it...adjust the settings run some more laps to get the feel for the effect of the changes an so forth.....this might actually take a few weeks
Week 4 - Add the next level of adjustable parts. Use default settings.
Week 5 - Repeat "Week 3"
Week 6 - Add the next level of adjustable parts....
and so on.

Maybe some setup god could actually map out something like this that could be worked through at an individual's pace based on how much time they can put into it. It may take one person a week to work through this vs someone else it might take several weeks or even months.

Pardon my ramblings but after reading your post (that I realize restated your original goals) I realized I am not going to learn very much from this whole process. IMHO each week there are too many variables (car, car layout, HP, etc.) to really begin to understand the settings (for me anyway).

But I guess this is a function of the amount of time I have to invest in this series and not a fault of the series itself.

So I'll get off my soapbox now. I probably should've addressed this in a PM.

- 2 complete laps (unclean)
- then 15 restarts or so
- finally a clean lap
- 76.7 total miles

T10: 6'31.201
 
first clean lap, 6'37.xxx, 300 total miles

still using stock semi-racing settings

If the point is to learn to set up a car, it would seem that running the same car week after week would be a better way to teach this.
True, that would be a more scientific way of doing but I think it would be boring.

The way I do it is buy the new car, change oil and take it straight to the track. I like to see how it behaves before modification. Turn off the driving aids and try for a clean lap (doesn't always happen, 1 hr).

After an hour playing around with that, I take it to the tune shop and do the full mod job. I go back to the track and try to make a clean lap. I seem to be able to make a clean lap pretty quickly since I've already warmed up in the first hour. Usually less than an hour will give me a smooth, clean lap (1 hr).

Then I check out the forum and see what other people are doing. Then I go back at least one more time during the week to change the suspension settings and try to improve my time (1-2 hrs).

So, yeah, 4 hours is a lot of time just to get one fast, clean lap, but that's how I enjoy doing it. I'm not the fastest driver, but I like going through the process and I just like driving the cars.

For me, the "hand holding" comes in the form of Dave or Small_Fries posting their settings. I plug those in and see if I like what they did. Sometimes I do, sometimes I don't. By the end, I feel like I have the car set up as best I can for me to make my fastest lap.
 
How are we handling time submission if the PM service isn't restored? Email or public post in this thread?

I have a clean lap to submit (though, there's room for improvement if I can find the time for another session).

OK Goixoye you could have addressed this in a PM, but as you put it on here i feel its only right i respond on here. :)

When i take into consideration the fact i have to test cars for the following week of the series i actually run the same if not less time than yourself on this, usually i am able to produce a good enough lap in the first couple of days to submit, i spend the extra time i get/dont get trying to better my basic time.

The 1st original goal for me was to provide a series dedicated to the Nurburgring and all of its greatness, to do that in 1 car would have been boring i feel and more an object in car tuning than a race series.

My 2nd goal was to offer you guys which car you drove every week and then in a controlled way up the power and power to weight ratio every week along with the rest of the tuning parts until we reached racing machines.

I am trying to provide a certain element of "Hand holding", I try to update the results and feedback thread each week with what sort of set up seemed to work and we seem to have the basics in place to tackle FF/FR/MR/4WD cars that display bias to understeer/oversteer, ie we seem to move in the right direction each week.

You mention having a "set up god" walk us though each week, but who is there to do this?? GT4 physics are different from real life and as far as i can tell nobody seems to get a "correct" answer on gtplanet when asking about settings and tuning of parts like suspension. Maybe what the NRS is doing could provide some sort of results for others to look over and apply to their own car/track situation and help them move forward also....?

Im not sure what else to say really, The result and feedback section i was hoping each week would get visited a lot more.....which would help situations like yours, I dont know.

Im still enjoying producing this series each week but taking the critical comments and the negativity is quite hard and i feel its getting worse perhaps, why not just enjoy it regardless!!?

I would be interested to hear others thoughts and comments on this, is the NRS a bad idea?

Dave
 
Dave,

I'm sorry I sounded so negative. That certainly wasn't my intent. I have enjoyed the series...even though so far I don't think we've gotten to drive the car I voted for yet.

For me the merit of the series is in the competition. And learning the Nurb. It's actually fun to drive the various cars with various layouts. I really enjoy stepping the HP up each week and watching my time come down. I've become hopeful that by the time this is all through I'd actually maybe be able to beat Mission 34.

When you restated one of the goals of the series (to learn setups) I realized I wasn't going to achieve that and became a little dissappointed...I remember when the series was first proposed I thought I'd love to learn how to do do set ups.

I know where I'm going to finish each week...usually somewhere not too far behind Koly...no matter how much time I put into things. So I'm considering dropping out and possibly devoting the time to trying to teach myself how to do set-ups. I'm not quite sure how to do this. I guess I'd start like I've noted above and see where it goes.

I realize it might be boring to drive the same car week after week but how else can you learn set ups....same car...work with just one set up item at a time until you learn it effects. I guess one could make moderate increases to HP or changes to tires to make the cars feel different to keep it interesting. That would produce quicker times amoungst competitors and that way it could continue to be interesting despite use of he same car? Maybe the initial car chosen could have a racing counterpart...RX7 or RX8 or NSX or Ford GT or Subaru Impreza or.....???? That way maybe at some point in the season you could switch over?

I'm truly not trying to be negative or belligerant or hurt your series. I'm also NOT lobbying for you to change the series. I was just brain storming some way to achieve the goal of learning to do set ups within the context of a series with competition.

I'll stay out of your threads with these sort of comments.

Truly I have enjoyed the series to date. You'd think that like driving the same car each week would be boring that driving the same track each week would get boring too but so far with various cars, car layouts and increasing the HP it has been quite entertaining.

Its ok Ronny, regarding knowing where you may finish each week, im the same! Im always seconds away from the quick guys and know that its down to my car control and experience with OLR, im fairly quick on the Nur due to driving it more than all the other tracks put together since i bought GT4.

I hope that you stay with the NRS til the end, the series is stronger due to the people who show the dedication to run each week, your one of them, im sure your set up knowledge will be better by the end. (And you have come up with a fantastic idea for a follow up series 👍 )

Dave
 
Goixoye, you're a better driver than me ... I *Still* haven't had a clean lap and probably will not be submitting a time this week if I can't nail one :(

No setups this week? I'm finding the car is skittery, exhibits understeer and oversteer tendencies and bounces too much ... and when the back end loss traction, it's all over. I'm trying to tweak stuff here, but really having no success.

EDIT: 6'28.889 :scared:

This is waaaaaaaaaay harder than it should be :p
 
damn... i just realized i forgot to send my time in LOL...

oh well...
 
Er, RedOak, the deadline is 9pm GMT on the 5th.

That means there are about 16 hours til deadline if my maths is correct.

Plenty of time to submit.
 
Right, lets have a speech in here....


Excuse me if i rant.

@Koly, get those ride heights up, and the springs set to 10.2 front and 10.0 rear and use 2.5 front camber, and 0.5 rear and then remember this:

When braking, start to turn the car into the corner, this will increase your stopping distance, the more steering you apply, so compensate, think ahead. As the car nears the point of no return for the corner ahead RELEASE THE BRAKE. The BMW will then start to pivot on the settings listed above, and once its nose is halfway towards the direction you are trying to go in, APPLY GAS and the ass of the car will do the rest.
Opposite lock depends on how smoothly you apply the gas.
Hit your right foot down too hard on your purple framework, and the ass is in the grass, but apply smoothly like you're trying to stand on some jello without breaking it, and you will sail through the bends. You arent far off a target time anyway.

@ everyone: 5 or 10 seconds are lost on the ring so VERY VERY easily, dont lose heart!
I often complete a lap in a car, and im 11 seconds off the nearest minute barrier (most stock cars of 276 to 330 BHP will finish a lap in 8'11 on N2 tyres on your first attempt) and i dont think "oh god i managed the fastest time there and im still 11 seconds off a 7 minute time"..... i think: "hmmm..... ok straighten that bit up where i clipped the grass, get the Karussell right, and through the twisties i need 2nd not 3rd in places to drag the revs back up, and hey presto! i have a 7 minute time..."

This is how to look at the ring.
10 seconds is not unachieveable at all.

@ Dave: Dave i love this series, and provided i can get to a pc before 9pm tonite, i will be submitting, but i forgot to check my overall submission time before work this morning and so may not get home in time to look at it, we'll see, but anyway, i think the way you are addressing the views of your racers, and the circuit/series in general is adult, concise, and correct. Hats off to you.

I thoroughly enjoy what i read in here, and what we have run so far, and i dont want it to stop.
Thank god Goixoye came up with a plan for the next one!

Speaking of which:

@ Goixoye: Tuning is a royal pain in the ass, its time consuming and often you end up with a worse car than you had.
Things to consider:
A car that has been tuned for someone else, will not necessarily work for you.
Each element of the car affects its handling, including drivetrain (ff, fr, 4wd) gear ratio (more or less grip through power delivery) spring rate and ride height (depending on course).

The consistent element in this series is the track.
The Nurburgring is used by the man for testing cars in all situations, because it has all situations within one lap.
Its too bumpy, yet has flat sections, its twisty, yet has flat out areas of massive straightline speed, thus it is a nightmare to tune for because it has everything.

I approach GT a different way, and maybe it will spread some light for you.

Firstly, i dont intend to offend, so dont find me patronising on purpose, its just being VEXD all my life tends to make me speak like this, but hey, im trying to help:

If you have a particular car you loved from the first corner you drove round, name it.
This will be a particular type of drivetrain, more than likely FR.
You liked this car because when you turned left, it went left, and when you turned right, it went right.
This car is what you should turn every car you drive into.
How do i do that though David, you say? This is my point David, you say....
Well, ask.
If you dont know, then ask.
Small Fryz is one of the biggest hoarders of information i know, both in his head, and in his multiple PC's at home.
That guy can research and tell you anything, and the difference with him is, he will.
If you ask, he can tell.
Trust him, he doesnt know everything, but he has it all written down from the people who do, if he doesnt.
The best thing to do with any car you are trying to tune and arent winning with, is look at what it doesnt do that your favourite car does, and then try to rectify that.

Hell, i remember one week, we were racing Integra Type R's round deep forest in GT3 WRS, and we used some settings that turned the car into an FR! i know what it loox like, but we did!
That thing had oversteer!!!
Its front wheel drive for blummin's sake.
:irked:
Anyway, what im trying to say is you should try to recreate your favourite car all the time, by altering the handling, and always remember to lap a track.
If you change a setting, then take one corner and think you have felt the difference, you havent.
Lap.
Then decide if what you have done is right/wrong.
Put simply, the gearbox ratio if shorter will give you more grip, due to intense power delivery. A longer box means the car can wallow in gears, and if it isnt being told a direction to purposefully travel in, then it will be more likely to drift around on the course.
The ride height lowered will give you more stability on Motegi, cos its flat, but not on the ring. raise it if youre sparking in a replay.
The springs need loosening if the circuit is bumpy at all, unless the car is wayyyyyy to soft to begin with.
Look at replays.... are the wheels dissappearing under the arches on bumps? maybe its too low/soft then.
Camber adjusts whether a car oversteers or understeers through turns.
Slide the bar wayyyy up on the front first, then see how it turns, anywhere between 2. and 4. degrees is fine.
You dont like what you get, slide the rear after you've slid the front back to where it was, and try that. Got something better?
Try to equalise somewhere.
Lastly, cos im running out of skin on my fingers:

The tyres we use, the brakes pack we use, the top speed of the vehicle we use and most importantly, the weight of the vehicle we use all have an effect on whether its going to go, stop and turn when we want.

Always consider these things when tuning, write them down, and think ahead.

GT is always pre-cognition, you should turn before you think you should, and stop before you think you should, and try to guess the cars characteristics before you drive it.

Good luck to you all, and please feel free to rip my comments apart, i have that kind of a life on a daily basis, the GTP racers will make no difference.

I EXPECT Small Fryz to do it.


I hope this helps.

Keep it up Dave, i love what u do.

VEXD out

:irked:👍
 
oh man!! LOL you're right! Usually its on sunday, but since the NUR incident... ahhh and such a good time. Excellent! :)
 
Time submitted, and voted for week 8 Lightweight challenge :scared:

Great post there Vexed, thanks for taking the time to offer some suggestions and
advice on how to go about the black art of suspension tuning (muchly appreciated ) 👍

Good luck, See you all at the finish line ( if you wait for me that is :sly: )

Steve
 
I believe my final splits were

44.4
1'18.7
1'47.1
2'37.8
3'15.6
3'42.7
4'xx.xxx
5'1x.xxx
No idea
6'18.4

Found an extra .6 last night, but its too hard to get those splits consistantly. Was hoping to get around 6'16.5 but no more time.
 
eh crap... i had a crazy busy weekend and forgot to submit my time, and going to be at work + classes well past the deadline... :(
oh well; happens to everyone sooner or later.

if anyone was curious, my lap from the 30th was 7'03.something-i-can't-remember

eh well... always next week.

Put simply, the gearbox ratio if shorter will give you more grip, due to intense power delivery. A longer box means the car can wallow in gears, and if it isnt being told a direction to purposefully travel in, then it will be more likely to drift around on the course.
The ride height lowered will give you more stability on Motegi, cos its flat, but not on the ring. raise it if youre sparking in a replay.
The springs need loosening if the circuit is bumpy at all, unless the car is wayyyyyy to soft to begin with.
Look at replays.... are the wheels dissappearing under the arches on bumps? maybe its too low/soft then.
Camber adjusts whether a car oversteers or understeers through turns.
Slide the bar wayyyy up on the front first, then see how it turns, anywhere between 2. and 4. degrees is fine.
You dont like what you get, slide the rear after you've slid the front back to where it was, and try that. Got something better?
Try to equalise somewhere.
Lastly, cos im running out of skin on my fingers:

The tyres we use, the brakes pack we use, the top speed of the vehicle we use and most importantly, the weight of the vehicle we use all have an effect on whether its going to go, stop and turn when we want.

Always consider these things when tuning, write them down, and think ahead.

GT is always pre-cognition, you should turn before you think you should, and stop before you think you should, and try to guess the cars characteristics before you drive it.

Good luck to you all, and please feel free to rip my comments apart, i have that kind of a life on a daily basis, the GTP racers will make no difference.

I EXPECT Small Fryz to do it.


I hope this helps.

Keep it up Dave, i love what u do.

Maybe the initial car chosen could have a racing counterpart... RX7 or RX8 or NSX or Ford GT or Subaru Impreza or.....????
Ooh! I like this idea but maybe with a twist...

How about each car is used for 2 weeks.

Week 1 - Stage 1 modification package
Week 2 - Stage 2 mods (full racing suspension, tire upgrade)

Stage 1 mod package:
- sport suspension
- low-end tires
- various other goodies for moderate power boost

Stage 2 mod package:
- racing suspension
- tire upgrade

This way, we can see the difference the suspension tuning really has on handling performance (and the effect of non-power upgrades on lap times). Perhaps the tire change over-complicates things and should be left out but I think it would just make it more enjoyable.

@ Dave: Dave i love this series... i think the way you are addressing the views of your racers, and the circuit/series in general is adult, concise, and correct. Hats off to you.
Ditto
