2011 STi - DCCD Explained + Mountain Road!

[nhirata10]

Are you sure that the center diff is forward bias? I was always under the impression that the DCCD was rearward bias? Because isn't the whole point of having a DCCD controlled awd system to increase mechanical grip while keeping performance? Plus on the Subaru global site, they say that the system "incorporates a 35:65 front and rear torque distribution..." So wouldn't it make sense that the words are respectively placed? Which would mean that the system is rearward bias?

opinion.

Great video!

[discogodfather22]

Nice of you to make a video. Not really any insightful information other than something read out of the manual or marketing material. The torque variation is 15%, it doesn't make that much difference. That's the marketing division pushing torque biasing.

What would be a good setting for snow driving?

Having my car in "Lock" and going around a fast corner is what cause me to total my car.

It pulled me off the road, hit trees at 60mph!

Live and learn.

[grove1104]

@HighCardWins Don't know what your talking about. I put my STi in full lock when I'm on my favorit twisty roads because that gives me the best grip because its a 50-50 torque split helping to eliminate understeer.

[GeorgeRR1978]

@grove1104 I am afraid to put in lock at high speed corners because I think that when you loose it, you just fly without any chance. I prefer the auto minus with more traction to the rear. What do you think about that?

[HighCardWins]

2012 STI on the way! But I hate the new wheels.

[AMTonyT]

If you have a 2007 STi, This applies to you too! The 2007 has a very similar or exact same DCCD setup as the GR(2008-present(2011))

[SparkDischarge]

@5:28 'mainly these cars are front wheel drive'

I think you want to go back and edit that out, because that is flatly wrong.

All the DCCD does is control the programing, which adjusts the generated frictional resistive torque, on the center differential

This is not a clutch that is used in lieu of a center differential, like the Subaru 4 speed/CVT automatics.

[onbooSTihooning]

@SparkDischarge I never said it was a clutch. I know that it is an electronically controlled system. I say that these cars are mainly front wheel drive because the front is where the majority of the power is delivered. How is that wrong?

[SparkDischarge]

@onbooSTihooning It is wrong, because the torque split of the center differential is rear biased. 41/59 in the most contemporary version (35/65 in the previous iteration)

So in a turn, if the computer decides to apply clamp load to the clutch, that increases rearward torque distribution.

It is only after the rear axle has spun up (hopefully you have counter-steered), then the application of the center clutch can transfer torque forward.

[onbooSTihooning]

@SparkDischarge From what I know, the torque split is max around 60/40. If you are right, that is news to me. Can you send me a link of this information?

[SparkDischarge]

@onbooSTihooning Go to subaru-global. commercial,

Go to the 'About Subaru', select 'Subaru Technology', then select the DCCD information tab.

[onbooSTihooning]

@SparkDischarge Thanks! Check out the video to see the correction.

[SparkDischarge]

@onbooSTihooning Correction, all you need to do is mute that part ;)

The rest is pretty good.

Im a newbie 2011 STi owner(5-door). Loved the DCCD vid. Very clear explanation. Thanks for posting!

[daezednz]

Nice clip mate, i'm in a older 2004 model but that helped make more sense of the controls. cheers bud!

[blowupuate13]

Oh thank you so much!! This makes perfect sense!!!

[elgusi2010]

Hey man !!! one of the best videos i have seen explaining the dccd, if not the best.

I have one question maybe u can help, wen street racing in a straight path, what set up is the best to have full power to all wheels? Thank u and great video

[onbooSTihooning]

@elgusi2010 Thanks man! I am glad you enjoyed it. I would try a variety of different set ups, but I think for maximum traction, try locking the diff. That would make sense to me.

[pghaffari]

nice video man, thanks a lot

[DVDA83]

Great job on this one.

[ZeroTechSkilz]

I also have the 2011 STi and was wondering your thoughts on the best set up for 1/4mile. I generally go auto- and turn the VCD to traction or green.

[onbooSTihooning]

@JackPipper Looks a lot faster then it is because of where the camera is mounted.

[Tylos47]

It would be great if you did a video explaining the launch control and how to use it.

[onbooSTihooning]

@Tylos47 I have not used it myself, but if I do, I will film it.

[Spartan198323]

do mind letting us know what u do for a living?

[grove1104]

@Spartan198323 My two cents on how to afford this car at a young age. I'm 25 and bought my 2011 STi with 7,500 miles on it for $27,000 in Aug of 2011. It has a reconstructed title on it and is as good as new thanks to *Silverline Automotive* where they specialize in rebuilding Subarus. Thats about $7,000 I saved!! I took out a loan for $23,000 and payed $4,000 cash, $380 monthly payment, insurance $750 every 6 months. It helps that I work as a Bellman/Valet and pay no rent.

i requested this video. Thanks onboosti!!!

STI RULES!!

OMG FIRST! i love when you post long vids!
