ok here is the sets,
2 laps, wrong gears, and no tuning from what it had. 1.14.483. an easy few seconds improvement can be had on the tune its got. i am pretty rusty on deep forrest, but no excuses as i totally wrecked the first lap. here is the tune its got.
everything off except 1 on abs.
trans set to 193
565 hp
1085kg
-9 f/r
8.4/6.5
4/4
4/4
2/2
-1.3/.-0.5
-.02/.16
i never touched the diff.
easy tweeks should be higher springs and gears. i will be able to mess around tomorrow but im tired.

Just ran 1:09.594***
Impressive... well still working on mine, back and forth between the woods and laguna seca < camber tuning track... ran a 1:22.833 there with 532hp, which is about a second faster than I when it got there so if it carries over to deep forest should get another second, then I can tune that drivetrain up to max.
Kalmiya117, here's an idea for this thread, since you started it. If you feel like changing the first post and topic, perhaps convert this to a Tuner's Garage Time Trial Battle... put a few formal rules in place, like new time submissions must include a screenshot (ideally in frame with your psn id at top of screen, if it is... i cant recall... but if so we can verify it goes with submitted ghost) and ghost replay, then we can post the ghost replays in the top 10 it was a clean valid run and have our own leadersboard event.
Racers should be honest, and if they used a garage's tune mention it, then we have a column for a tuner credit also next to each entry. [Tuner X's; Personal; Modified from Tuner X's; etc.] If you have a super secret personal tune it doesn't have to be made public but just mention it's yours or the garage's (or modified from).
Be a fun way to keep an ongoing long running event format where tuners aren't having to meet a deadline for an entry, and test drivers can drive multiple tunes at their leisure.

For what it is worth, I used my 70 Challenger R/t RM to win the historical cup the first time. And actually here is a picture of it!
I know this is sort of off topic, but I would love to see your tune for the Challenger R/T.

Tuned mine myself and after that 1:09.594 last night I'm almost certain I can get at least 0.200 faster. I have to fix a little oversteer on corner exits.
One main problem I was having on DeepForest was the front end losing a lot of traction over the bumpy sections and especially topping the hill just after turn one(1). Its never good for your front tires to come off the ground*

Yep. Well that's grip for you, that means you have plenty of it on the rear tires which is good. Double clutch and semi-race flywheel make that wheelie popping more evident, too bad you can't down spec it on RM cars but on many standards, a sports flywheel and/or single clutch could possible give better lap times. Modify your driving and let off throttle for a fraction of a second at crest probably be best if it don't slow you down too much. I took a nice photo from one of my lap replays with mine launching off the top of that crest with all four wheels off the ground, it'll go with the tuning data when I post it, it just looks badass.
Are you driving with with pad and AT shifting, pad with MT shifting, or pedal and wheels? That would be useful to know as well for comparing our lap times. I'm only using DS3 with AT.

I'm on a wheel. Big difference. Better lines.. etc.
You need to run with Manual Trans. You'll be able to brake later with downshifting.

If you have some free time today (or anytime, it's a bit lengthy) would you mind reading the following write up I did and then run through it with your DFGT and report back your findings as to whether or not the results experienced with DS3 pad and AT shifting are reproducible with clutch pedal and MT shifting?
Edit: If that even has a clutch pedal? Googling it I guess it doesn't but I'd still like to see feedback from sequential shifting.
How to select and optimize drivetrain components, and the not so obvious effects.

Purpose would be to determine if you can notice any discernible difference in shift performance or engine braking by using the single clutch over the double clutch, or if the semi-race flywheel has a similar impact on your driving ability with a wheel. The results of testing with DS3 w/ AT was that the combination of single plate clutch with sports flywheel was superior to every other combination I tested (for supplied test car spec).

Care to share your setup? And are you using a wheel?

I am aware of this, but I was pointing out my test conditions for standard cars that can be down spec'd and just wanted his feedback on those scenarios.
And for his setup... he already did post it.

Opps, I did not see that earlier on my phone. A friend was wanting to improve his track times today and I tried his setup which was much softer than mine, and close to the guys above (dream) and I ran way quicker with less effort. So I guess the camaro does prefer a soft setting.
I went back and tried to get the lower parts to see myself. I personally never tested that theory.
And isthedream, that time is pretty good! I snagged a 1:10:763 today online with new-er setup but I will try yours out for sure! I would imagine with the wheel it is much easier to control and fine drive the car. I myself have never used AT. Can't stand it. I really wish my real life car was equipped with optional manual.
Maybe we can all set a date for perhaps, a Track day? That would be cool. Or, We have it setup where we each run say, 6 laps. And the others just watch. And overall see who can run the best laps?
Although the whole having a wheel deal does help out alot.

I tired using itsthedreams setup last night, and it seemed kinda pushy in the corners. I believe this shows a difference in the cars behavior between the DS3 and having a wheel.
To find a common good setup is proving to be difficult as they all have many variables. We are have different lines in a way, shift points.
Although through this thread I am learning and improving. I am now finding out the Camaro does seem to like the softer springs rates. I do believe alot of cornering ability is achievable through L S D tuning as well.
I ran a 1:10:763 with a friend's tune online the other night. The only issue was that his setup made my car kick out a bit on the first turn exiting which I felt made me lose a little bit of time. But the turn in, and cornering was better.
I also changed my driving style to stay in a gear longer through a turn rather than downshifting.
I have to say, this thread is achieving exactly what I wanted. Different Ideas, setups and thoughts that overall improve everyone's game play.
Although I am starting to believe that micro tuning does not change that much with the suspension. Anything less than .5 increments seem to have little effect other than looking important. Thoughts?
And I do encourage everyone to post a picture of their camaro! These cars look awesome in many flavors!

If it wasn't for micro tuning my tune would have been up 3 days ago, but I squeezed another second out of Laguna Seca, haven't tested to see as that transfered to Deep Forest yet, too many cars and other bits I got to get to irl.
I identified one suspension setup that's probably optimal for flatter smooth surfaces and one that's better for technical circuits, each has their strong suite so it's choosing between the two for which is Spec A and the alternative, B.
Always room for fine tuning
Just completed the 90 laps at Laguna Seca in 2:24:15. I ran the car detuned and normally aspirated @415 HP. I applied Kal's second tune as it seemed more pliant. I set the final drive to 180 mph and it felt high. I never hit 5th gear the entire race. My fastest lap was 1:30:788. Finished 6 laps up on the field. As for Deep Forest I can barely eek out a 1:14 using a DS3 controller. Don't know how you guys do it.

I never use AutoTrans! Yuck! I think the Camaro prefers a softer suspension due to its dimensions, longer Wheelbase and wider Wheelbase. The wheel definitely has it's pros.. Better control and Accuracy.. crucial things while racing.
Some people think MICRO changes help 'when really... they only run a better lap than that of the previous'.
The only reason I lowered my front springs/dampers is because on deepforest the front end tends to come off the ground on key sections of the track.
I'm up for a track meet. whomever add me on PSN- itstheDRE4M
edit!(* From my experience from using DS3 before I got my wheel. I used R2/L2 for Accel/Braking. Gives you so much more control over your throttle and braking since you can be on them both at once. It really helped me out once I changed it up. *)

Well I'm more specific in micro tuning than to look for previous lap over next lap, but new high lap time can be an indicator, so can my speed through the last bend on deep forest, and speed into the deep U with the concrete run-off if utilized correctly.
For fun, try putting stupid amounts of camber on your car... I was getting full four wheel jumps off the top of the hill crests for some great Hazard County Derby style action, lol... only now gotta tune the Dodge Charger RM for the Duke boys to run.
The bit about L2/R2 makes sense I have played it that in the past with previous GT titles and other racing games but I had just gotten accustomed to the controller defaults using stick now. I might go back to L2/R2 and give it some tries for lap time comparisons.
- 195
- itstheDRE4M
I use the Data Logger to compare setups. I discard the lap board when I decide to make changes, but I save my best GHOST* laps once 'I think' I've got a good tune.. then I try and get more grip out of it or better turning ability. It's good to compare the amount of G-Force the setup gives going through turns letting you know just how much grip the car is getting along with the speed going through the runs.
I just had better luck with the L2/R2.
Make your suspension stiff enough.. you'll get airborne over a speed bump.

I'll get around to doing a suspension tuning article one of these days when I get the time. I'm still refining my process and testing alternative theories I get from the other tuners, if I can replicate them and prove true I adopt them, and debunk the others so they can be safely ignored. Takes quite a few run throughs to get a detailed understanding of the process, but now I got the hang of it I can rough cars in with decent tunes in a matter of minutes. That said, I started three days ago with a car that was probably at 98% of its end potential, and squeezing the last 2% out is the real challenge.
Finally got around to playing with the car for a few minutes this morning. Ill definitely need more time with the car, as there is much more to be found.
For reference, I use a DS3 with X for accel & [] for brake, auto trans (Old School, I know, haha)
All aids off, ABS 1
Best lap: 1.11.044 with consistent 1:11.1 laps (only ran about 5-6 laps)
Aero: 18/45
Trans: 186 mph
LSD: 10/25/15
Brakes: 6/5
Suspension:
RH: -12 / -10
SR: 11.0 / 10.0
Ext: 7 / 7
Comp: 7 / 7
ARB: 3 / 3
Camber: 2.5 / 1.0
Toe: 0 / .20
This was very easy to drive and get consistent lap times. I left a tiny bit of understeer in the tune and the front end is still a bit twitchy (seems to be the nature of this car). Would appreciate some feedback on the tune.

Understeer and the front end is Twitchy.. Did you think that your front end was a bit too stiff maybe? I run a soft suspension.. I'll try yours later when I get home. But I found a softer suspension works very well with me.
Yeah I'm using a wheel, but I'm still running 1:09.4xx best laps without AiDs.
I know for a fact that your front end comes off the ground because with comp-settings of 7/7.. that's very stiff let alone a 11.0kg/m spring rate. And typically.. EXT should always have higher values than your compression, but.. that's cliche.
Why use a soft suspension on DeepForest? Because your front end tends to come airborne numerous times.
- Down the main straight before your descent down the hill into turn one.
- After exit of turn one(1) entering turn two(2). *Crucial for maintaining speed.
- After exiting the first tunnel there are two spots where a stiff suspension will lift your front tires.
MySetup-
You are absolutely correct. I fully intend to soften this thing up when I get some time to play with it. It lifts the front tires right at the end of the main straight and right after turn 1.
On most of my cars ext>comp, but for others equal values seem to work well. Sometimes comp>ext for me. Could just be driving style differences. I will definitely try your tune tonight and see how it goes. I doubt I can get under 1:10.xxx without a wheel, but Im almost positive I can get in the low 1:10 range. There was a lot left in the car. Ill post a new tune tomorrow, thanks for the help.

I ran itsthedre4m's setup when I got home and was instantly cutting 1:10.9xx laps. With a few changes to LSD settings and some minor suspension tweaks to suit my driving style, I was running 1:10.7xx with a freak 1:10.574 lap. Thats about the best I can do with my controller, I really need to get a wheel.
The car really really likes a soft setup, thanks for the tip. Also, I have been using Deep Forest for tuning a few cars here and there but I find it very difficult to get consistent lap times. If you change your line even the slightest bit it can take up to .5 sec off (or add it on) just like that. What other tracks are you guys using for tuning? I really like to use Nurb GP/D because I can get extremely consistent times on it, however, it usually causes me to set up the car too stiff because of lack of elevation change.
