favorite dccd setting for track event?
�

well i'm new to the opportunity of being able to adjust the dccd so i was just curious as to what everyones preference was? and what car did you previously come from before your subaru ex)fwd, rwd, awd. this of course effects preference because of what your acustom too.

DCCD set to auto for track days. I've tried a few other settings and auto seemed fastest.
I used to race a GT-3 RX-7 (RWD).

Honestly, the auto mode is fastest in my experience (in autox and timed track laps). I haven't switched it to manual in while, but I think I will play with it some this next track season. I also don't think I've given the manual mode enough time on a track I know well. The times I have had it in manual (set to open, full rear) I feel the car tends to oversteer more (as expected) where in auto mode you'd be able to get the power down in a corner just a hair faster.
The only other experience I have in HPDE is in a WRX, although my BMW 525i (91) is pretty fun for a big ol'car.

We use a differential controller that let us use it in an auto mode we have found that his works best, so for stock the auto mode is usually the quickest

I've tried different settings at autocross and hillclimbs. Sometimes various manual modes felt better, sometimes they felt worse. [u]Times[/u] were always faster in auto, so I haven't played with it much this year. I used to autocross a RWD Miata.

I just started playing with mine. I was told by an instructor that drives 2 different AWD cars, that it would be more controllable on a dry track (2+ mile road course not autoX) adjusted all the way to the back. Because you could get the rear end out a little and subsequently plow less in the front. From what little I've experimented with, I agree.
It may be because my last car was a Cobra and I'm used to driving with the rear end loose all the time. I will do more research at the track.
Not that you care about this but I think on wet asphalt I can perform some semblance of a donut with the DCCD in the full rear position. Donuts and good looks are the ONLY two things I miss about the Cobra. :alien:

My instructor and I played with it on a short course with a lot of braking... felt no handling difference whatsoever. (Mosport DDT)
The effect has a lot to do with what modifications you've made; the closer that you've brought your car to neutral handling, the more significant that DCCD adjustments will be. Poor friction conditions also make the effect more noticeable. With 24mm sway I notice more of an effect.
In heavy rain at the same track on a later date (with sway bar), I found Manual with one notch rearward from lock to be the most predictable. Then just dial it back to your comfort level of when you want oversteer to occur.
Drifting in deep snow, the conditions change so quickly that I usually use auto in this case. Full lock isn't that bad, either.
The fastest AutoX'er in our league used auto all year. The second fastest used manual with one above full rear lock.

To go quickly it depends on the conditions and track, auto is easy to get speed out of but not 100% predictable, i prefer playing with the manual settings.
I havnt driven the auto setup that much though.

I have always used fullauto in the dry.
In the wet you will definitly want to try 1 or 2 from full lock.

I have always been fastest when autoxing with it set to the rear. I tend to understeer like crazy when in auto.
| Subaru Gwinnett | 01-11-2005 08:09 PM |
The '04's have DCCD-A and the '05's get DCCD-B, which throws in the yaw sensor. The transition of torque exiting the corners with DCCD-B is AWESOME. Stock suspension will likely do best in auto in both dry and wet. As you stiffen the suspension you will likely want to play with near full lock in the wet.
The road race car with 670 pound springs front and rear was a nightmare in the wet in auto. It would push horribly on the way in to the corner and as soon as you picked up the throttle at all it would "lightswitch" into oversteer. Not uncontrollable, and actually quite fun to drift off the corners, but not fast. In the wet 1 back from full lock was very predictable and quite fast. Full lock understeered more and less lock was more of a switch.
The '04's are awesome track cars even stock. Tire pressure, front camber and sway bars and they are just sick. That said, even a stock '05 in the dry has truly shocking corner exit front grip. It's not fair to all the other cars ;)

In the 04 I felt like I needed the DCCD to full rear to compensate for the understeer. The first corner I took at an event with the 05 I almost plowed into the inside pylons as I was turning earlier like I would have in my 04, but the 05 gripped like mad. So far I have left the DCCD in auto with the 05, but its only been 2 events so far (rained out the other ones so were canceled), and can't tell which I want to use yet. But I think I might prefer the manual full rear as I have been a RWD guy for most of my life. I just can't feel I want to trust a computer to do the handling for me. In my old BMW Z3 Coupe I had DSC (Dynamic Stability Control). In the dry, we all would turn it off. But one event at Buttonwillow it was raining like mad. So I left it on thinking it would help in the wet. When I went to brake for a corner, I expected the car to go one way, but the DSC kicked in and made the car go the complete oposite - taking me by total suprise and I almost went off course. Never left it on since!

The DCCD computer is simply smartarar than you or I.. Auto mode is the best, IMHO. I've played around with manual settings on track, mountain road and autocross. The car never felt faster (and times never reflected an advantage) in manual mode.

You cant really compare dsc with the auto dccd. The dsc is designed to keep the car from getting away from people, it doesnt always achieve that but its design intent is saftey. The dccd really doesnt do anything to improve safety or traction control, its just made to get you in and out of the corner quickly.
| klattery | 08-10-2005 09:45 AM |
Last season I ran Auto mode on my completely stock 04 STi for autox. After several tests with expert codrivers we all got fastest times with Auto mode. Car did not turn in as nicely as full rear, but it pulled out far better.
This spring I installed a Cobb front swaybar and added negative camber up front on stock camber plates to -1.5 (I highly recommend these mods for retaining stock class). These changes improved front grip much better, and you can pull out of a turn faster. Now my fastest times are with full rear.
All of this assumes dry conditions.

The problem I've had with auto mode is that at the limit of the car, mid corner, the DCCD changing settings does upset the balance of the car. At 80% of the limit of the car it's not an issue, but the faster you go, the bigger problem it becomes. Because of when and how it happens, it makes sense that Auto mode is faster on an A-X course, but I have found my fastest lap times in manual mode closer to full lock than you might expect, with the car understeering a bit more than is really comfortable. If the car understeers and is 0.5 sec/lap faaster than neutral handling, well, it's still 0.5 sec/lap faster. I have had the same reaction in every 04 STi (haven't driven an '05) I've driven on track, and I've driven a couple with different levels of prep.

Feel doesn't matter worth a dork.
The only way to know how to set it better is with a stopwatch and a good testing driver (fewer of those than good race drivers) and a lot of time at that track - then you only have the answer for that track. For anyone doing a DE - there are a multitude of other things you have to be more concerned with than the DCCD setting - leave it on Auto you aren't a consistent enough driver to lay down two laps at the same time with the same settings less likely determine which setting is faster. The point of the DE is to become a better driver - not fiddle with the car's settings you can't win a DE.
However for skid pad work, low lock is best:

kinda curious... I haven't tracked an '04 STi in the wet, but autoxing it in the wet, it seemed to be VERY touchy ie snapping from understeer to oversteer in a hurry. I was more comfortable taking it out of Auto just to make it more predictable, since in auto mode there were numerous times where I'd use the same throttle input in the same corner and get different results in terms of rotation.
Does the '05 behave any better in the wet? It seemed like the '05 was a bit more controllable in rotation while exiting corners in the dry than the '04.

I found throttle steer very predictable from hot august conditions to downpouring october conditions in Auto mode on the track.
But any discussion of transition such as this isn't really good guidance for the original poster - unless we are going to discuss the suspension setup that gave us the results we mention.
I mean I ran -3.0* front camber, -2.0* rear camber on pink springs and hardened top mounts and front and rear strut bars plus cusco ARBs and a 4 point roll bar - my good experiences in transition can't necessarily be carried over to a stock suspension and oem alignment. Oh and add to it my exhaust and ecutek tune and my torque available was also significantly different. Then add to it that I used Ferrodo DS3000 pads on the track, so trail braking changes the entire attitude going into and through the apex. Driving my car and my friend's essentially stock car were totally different transition responses but they were consistent within the car in auto mode.
But the educational experience from the DE environment wouldn't have been improved in either car by messing with the DCCD out of Auto.

I have never done any testing in the wet, we just struggled keeping the car on track ourselves, but Javid here on the boards has had great results in running 2 from lock in the wet. We'll test next time we have a track day.
We were on fairly done MXs, which suck in the rain anyways, and the car was on skates. The second you got in it, the tires would light up and you were sliding. With my dry experience, we never even thought about taking it out of full Auto, but will try it next time it rains.

I think in a DE environment there may be benefit to taking it out of Auto and just leaving it somewhere. That way you take the computer's inputs out of the equation and leave the car's handling solely up to the driver. I think there's benefit in learning to be an adaptable driver who can manage equipment well, but managing non-linear differential behavior is a bit above what the average beginner/intermediate driver can figure out. I think most advanced drivers would be a bit confused by drastic changes in behavior mid-corner.
| RyanC | 08-10-2005 03:45 PM |
I run my mildly modified '05 (STI pinks) with the DCCD in Auto mode all the time on track. I never noticed the effect kfoote mentions, but I do notice that the ability to pull the car out of a turn is just awesome. The car will start to plow a bit on some turns, but feeding in more gas gets it back to neutral in a hurry. Now, I haven't experimented with a manual mode, just because I am new to this car on all the tracks I've been to this year, but with me leading my class for the season and one track record, I'm not going to change my style heheh

full lock was prdecitable,
dry track i have run auto and liked it, look forward to wet track

having done a ridiculous amount of active differential map development on these cars, I can mention to you a few things
(all the notes below pertain only to extremely agressive driving)
when setting the dial to low lock (note term usage as opposed to the misleading phrase "full rear"), you stand a very high likelyhood of breaking rear driveshafts (or conversely, in a special situation with a lot of power, a front driveshaft). Essentially in open mode, the diff will spin whichever wheel has the least resistance, which is usually the rear. As soon as it hooks up, blammo. Although many people claim to run 'open mode all day long with no problems', all I can say is that this may have been in a less abusive manner than what I am deeming 'extremely agressive'.
when setting the dial to auto mode, the ECU does not factor into account some tricky situations however does make it relatively easy to drive as it uses generally low values of lock (hence, oversteery but not too oversteery), except in a few cases, the few that you are most likely to encounter
Although there is the limited use of G sensor and also the use of yaw sensor in 05 cars, there is no calibration for grip, i.e. with changing surfaces and grip levels, what works in one level of grip is totally wrong in another
although lower lock is easier to drive, more lock is faster, and hence you want as much lock as you can get away with without making the car impossible to turn
aftermarket controllers do exist to enable the 'extremely agressive' drivers to have maps tailored to their driving style and/or car use (i.e. drag maps, fast road, dry track, wet track, ice, etc.). The most beneficial use of an aftermarket controller is full lock application under braking, which trails off with some throttle application. This makes it almost impossible to lock up a wheel (with abs disabed) under very heavy braking.
It should also be noted that the abs and auto mode also have some quirkiness, for proper active differential management disabling the somewhat 'unresponsive' ABS in our cars is preferable.
So what I tell people is, run it on auto, and if it is too oversteery, crank it up as far as you can while still being able to turn in (more lock *is* faster but less fun unless you really huck it in the corners), and if you are at the point where you wish it was doing something else, then its time for an aftermarket controller.
most people are not even using their front tires (i.e. are in counter steer correction, as opposed to slightly rotating understeer) so auto works for most.

This is basically the same conclusion I came to. Running the car at full lock, the car launched like crazy coming out of the corners, and very shortly afterwards I found the edge of the pavement coming out of a corner that I never really considered a corner before.

I found myself faster closer to full lock also, but I believe that's more due to my familiarity with FWD cars. I'm just more comfortable and faster in a car that understeers. Running it at full lock or close to it made the car more stable on braking and I could drive it deep into the corner and get on the throttle faster than with auto. Running it on open was hopeless for me, I've never raced RWD cars and I pretty much am lost when the rear starts coming around.
All this was in autocross situations though (~10 events), and the clock backed up these statements. I do think the results are highly dependent on my driving style though.

wow, thread from the dead.
Short answer is auto is great for the dry. The only time I suspect the Center diff is acting 'twitchy" (changing settings on me rapidly) is coming out of hair pins. This has never been really drastic, just something I have noticed after 10 hours of playing at a local track. Alot of it may be the rear bar and dampening. Even if this is due to the dccd, i find it quite fun and it certainly is very fast once your used to it.
In the wet use 2 from full lock. In the wet you can quickly see why, try a couple settings (2 from full lock, open, and auto), drive safe, have fun. Note that even in the wet you want to put the c diff back in auto for tight turns in the paddock / pits; else, tires will slip and the c diff will make funny diff noises.

Enjoy the track.
Short answer is auto is great for the dry. The only time I suspect the Center diff is acting 'twitchy" (changing settings on me rapidly) is coming out of hair pins.

Note my comments for wet are for tracks only, auto seems to act just fine in the wet on tight autoX corses.

i have played with the car a little more in the dirt and earlier said i liked locked, which is FUN and you can get loose and control it...
but i went back to auto, did cleaner lines that felt very slow but the clock said they were much faster---so much for how it feels!?!?!
