I have a my05 sti with dccd,

I was wondering if anyone out there can give me a quick break down of the differece in setting's

Having only had the car for 4 day's I have spent most of the time IN AUTO !

I just wanted to know or confirm what I think.

eg

I guess when not in auto the YAW sensor is enabled providing help with traction.

Lock

Must mean 60% rear 40% front...but what about the arrows

larger arrows at the top...does that mean more power to rear and the smaller the arrow the for 50 - 50 split becomes ????

Hope you can help as the driver manual does not tell you anything !

I read that post a while ago and still have a question (a bit thick you see!)

Where it indicates various stages of lock is that relating to how close it's getting to a 50/50 split (locked)

As standard the car is 65% rear and 35% front torque split so the DCCD gradually changes this to equal torque as you push the dial forward?

This is my interpretation - is this right?

Well have done some more reading and yes ! The lock option would mean 50/50 split rather than a 65% 35% split....

Well thats what I think........anyone ?

fully forward is diff free so 36:64

fully backward is diff lock so 50:50

it reverts back to diff free.....standard position.....so 36:64 is standard

diff free under normal driving conditions, and "diff lock" on gravel, snow, in the rain

scoobydooooo

diff lock is 50/50 split . right ?? thats the same as a non dccd scooby , are they meant only for gravel , snow , and the rain ???

Fee Muir

thats just what I got from the post above....

don't think it means that you can only use the diff lock on gravel , snow , and the rain ...thats just what its best for.....

another thing....

if fully forward is diff free so 36:64
and
fully backward is diff lock so 50:50

what are the in between bits? its not like a switch between the 2....does it gradually change?

tuscan57

isnt LOCK when its locked???????

Fee Muir

yeah...and free is when its fully forward.....so what about in between the two?

tuscan57

also as the post was in 2002 think its not relating to the 05.....

Fee Muir

ah...right

anyway....mine is a 1997 car so it will apply

was just thinking about it today.....trying to find out more about it before picking it up

tuscan57

i was led to believe that the 05 had a more extreme difference between forward (locked) on the DCCD-A. and rear which is pretty much RWD.........

To save a new thread I resurrected this one.

What is the optimum DCCD setting for track driving on a 2005 (55) STi Type UK?
