ive had a fiddle with it, but i'll be honest, im not sure what im doing! .. i know you can put more power to the rear wheels etc but do you need to put the lights to green at the bottom to do that?, or in red at the top? or into lock?? and what does lock mean??? lol

cheers!

drtchock

surely someone must know!! lol

Did'nt think mine was connected to owt!

drtchock

really suprised no-one seems to know!! surely theres some guys who do track days that know how to get the power to the rear wheels, it helps get the back end out

Mine's never been out of auto

I'd be interested to learn how to use it myself... and when you actually benefit from using it in manual.

I never use the water spray either... gimmicks eh!

drtchock

im pretty sure when its in auto it keeps it at a 41 (front), 59 (rear) power distribution..

when you put it in manual and push the roller up to 'Lock' that puts it in a 50/50 power distribution

if you roll it all the way back to the bottom green light i think thats something like 30(font), 70(rear) distribution.

i could be COMPLETELY wrong though lol

The thing i know is i have to roll it to the bottom setting to park it on the drive(cos it curves round whilst reversing)or it crabs like hell in AUTO!

It's not power it's shifting about.

Basically, fully open(green) will allow the rear wheels to break away or slip more, aiding turn in. Fully locking it will have the opposite effect.

drtchock

so would setting it to fully open (green) give you better acceleration from a standing start since more torque is going to the rear?

From a standing start, I'd just set it to auto and let the DCCD decide.

Layman's guide (my experience of it):

99% of the time on the newage car's just leave it in Auto, it does it's job well so should get out of virtually any situation (provided your in control of the car).

If you switch to manual (same as classic R/RA manual) then you have a few options that you only need to worry about:

1. Dial all the way back (bottom green dash light) is diff-free mode, steering will feel light and you will find the car oversteers more readily and the back is more willing to step out under power (have to watch it on this setting)

For dry weather and most of your driving use diff-free, when pushing the car dial it up to the 2nd green light (explained below) or 1st orange when you want max grip in the twisties at speed).

2. 2nd Green Light on the Dash (move the DCCD dial forward slowly till the light is on).

Not as much power will get fed to the rear wheels, this gives a good balanced 4wd drive from my experience but depends on what your used to. I like rwd car's and like to keep my car on this setting even in damp conditions so back steps out a little bit (but not as suddenly/violently as it does on diff-free) but the front end has enough traction and drive to pull me through safely.

3. 1st Orange (move dial further forward). You probably won't ever use anything above this setting unless it's snowing outside. At the 1st orange setting more of the power is being distributed between front and rear diffs so you get an almost full-time 4wd car (the centre diff starts to lock up so more of the power is transferred instead of slipping to the rears when you lose traction).

This setting is the safest in manual for wet weather driving and as I found out today you can drive at some scary speeds in the wet

That's really it, have a go in a safe place and you will have fun. When your parking etc leave the diff in diff-free or auto otherwise you put a lot of stress on the diffs (as you will find out, the car doesn't want to move at low speed).

Mikkel

Very useful, thanks. So you leave it with 2 green lights on most of the time then?

I may give it a whirl as also come from driving rwd cars previously.

Ditto, no idea how to use it out of auto mode + my car manual is in Japanese

My water spray is auto too

So bottom green or second bottom green for dry weather and first orange you come to from the bottom for wet conditions, got it!!

I've just started playing with DCCD on my Spec.D, and having come from rwd cars actually think that I prefer the handling with 2nd green light rather than default auto setting. Def. sharper turn in, more predictable and ride seems a bit more compliant too.

Mikkel

Same here. Just tried it this morning and it feels more balanced to me with that second green light on. Will be back in auto for the bad weather though!

magicgreg

Not had chance to test out the green light scenario as yet due to the appauling weather but did try the 3rd setting from the bottom which is the fist small orange light in the wet/damp.

The steering seemed heavier and more precise, more effort was required but it did seem to be a lot more controlable which inspired more confidence in chucking it into a corner in wet conditions.
