Can some one explain what the dccd does
i just want a simple explanation of what each bit does
auto
lock
green light lol

Also how can you check its working as it should - is this sumot a garage can do?

thanks

 

This isn't going to help you much but honestly...just leave it in auto!

 

It's a dial in the car that allows u to alter the power levels between the front and rear diff. Can't remember the exact figures. There should be previous posts on here about it or even search on google

 

Had it in my last 2 cars never had it out auto

 

It's a scale of how locked or open your centre diff is.

If it's locked, the same torque goes to the axles regardless of traction.

If it's open, the power will follow the path of least resistance and will keep powering the spinning axle if one end breaks loose. Typically on a car that's turning whilst on the power, an open centre diff will encourage oversteer and push you round.

The adjustment **** allows incremental adjustment between these two scenarios.

Auto is very slow go react when driving on a circuit and I always use manual settings in track. On the road auto is fine.

 

Thanks all
what does leaving it in lock do when you pull off on a normal road?

I pulled off in lock by accident today and my car juddered big time. Put it in 2 auto and it was fine

 

That's normal, even says in the handbook I believe.

Imagine a car moving when there's any amount of steering lock. All four wheels will be spinning at slightly different rates.

By locking the diff, you're effectively forcing the axles to spin at the same rate - so when you turn, either you'll get a clunky/bouncy experience or if you're going fast enough - you'll get one of the axles sliding!

 

i only ever use lock on the start line then flick it to the back, lol

 

I could never launch with it locked, how to break something.
I like mine turned forward a notch.
Think it Helps initial turn in loads, car feel a bit livelier tho

 

I`m talking 6 speeds and only for the initial get off the line with the gear already loaded up,

Did`nt realise it was you yesterday having launch issues on the start line, would have come and said hello if i`d known.

 

Cheers mate - uve put my heart at rest - thought it was a big problem and was worried it was gna cost me ££££ lol

Thanks everyone for ur input

 

No worries mate, was annoying really, I only managed one run plus the sighting lap on the handling, did a 26.5 so was up there.
Can't understand why I snapped 2 shafts. Then again the 2 previous sprints I've given the car hell on the launches. I few people said I would snap shafts at some stage

 

Your car looked mint by the way Gaz, really really is shrinking. Again I would have come and said hello had I not been up to my eyes in it

No worries mate, I saw it go both times but did`nt realise it was you, you didn't look happy the 2nd time mate

 

I was frustrated because going by my one and only time I was looking competitive and was sure I could get my times deep into the 25's.
That's motorsport tho lol
I only live 20 mins from elvington, so glad I trailered it now haha

 

Thats usually the way it goes mate, lol, I didnt do bad with standard(remapped) power, In fact i did really well pmls, Goes to show its not all about big power cars although i lost a second or two to the big turbo guys down the main straight and back part, ....the excuses will never end

 

I thought the handling circuit was really well suited to us lower powered cars

 

Low powered eh...you should try it in a full fat 182

 

Lol, I dont think anyone above me had less than 450 bhp...you looked like you were having fun tho

 

28/43 was a decent result as I had to drive back to Essex with the same tyres and I beat that caged track toy 'Teg so I was well happy. Only FWD to go quicker was Si's old track caged Dimma 205 and I think that runs an Mi16 lump

 

My blob STI doesn't have DCCD and when I was looking to buy it, a lot of people were put off with the car because it didn't have it.

To me I couldn't care less, so why is there such a hype with it?

 

these cars are all designed with safety in mind for your average driver; so the chassis is set up to understeer. DCCD allows you to address that set up without messing with your ARBs...turns the car from a bit of an inert lump into something far more entertaining to drive

 

You did well on Friday in that clio trails! Switching the tyres round bought you some time by the sounds of it.

I think I did alright too seeing as I was just there to fling it about a bit and remember what it did.

As for the DCCD thread, for those that know how to use it it makes a massive difference!

Standard gearboxes are viscous and redirect to wherevers slipping so when your in understeer, throttles only going to emphasise it.

A dccd box is a rear biased diff with an electromagnetic clutch to effect the amount of slip before it redirects the torque, meaning the ecu can be tailored to anywhere between oversteer and understeer.

When on the road, leave it in auto and the ecu will do its thing redirecting where you want it.

When its dry and grippy and you want some fun (like elvington Friday) .... leave it in manual and wind it rear and you have a much more steer from the rear drivetrain.

Only time youll need it to be in manual and locked is on mud or snow, and thats for improved traction rather than lairy sideways.

 

Cheers Will, was fun...great to see the flying fridge moving in anger

 

Ah ok, I drive like an old man anyway so I think if I had it, it would be lost on me!
