just fitting a new box to my rally car fitted with a dccd.2 question.if i dont power the dccd will this have any negative effects on the box?if i have a push button on the steering wheel which powers up the dccd for stage start to give max traction to all four wheels then drops the feed when button released,is this ok also?Idont have the funds at the moment to buy a contol unit.thanks in advance neal

 

Sounds familiar!

The dccd will run in open without the controller and will be a bit tail happy on lift-off in a bend etc, but not too scarey.
I rigged-up a 'start' button once for hard starts on a hillclimb.

The wires can be arranged to simulate the switched 'locked' position on the knurled wheel (do you have one though?).

I placed a momentary switch on the left spoke of an aftermarket wheel and a curly cable from that to the control wheel by the handbrake that I installed.

tbh I never had the nerve to use it AND I did not feel I needed it as the starts were hard enough in dccd setting.

You are really missing out by not having a controller, but one from Product would be the right way to go as it will do everything you need.

Fitting the stock dccd controller is a pain in the ***!

Neil,

Long time no see....
Arron and i have just done the very same thing to our 93RA rally car...
Although we have fitted the gems controller from steve simpson.
As Graham has already said, the diff will run in the open position with no power connected, but 12v will lock it. Im not sure if its a good idea just to put 12v straight to it though...The input to it should be current limited in some way.

hi 911 and j-k
thanks for the replies,i think for the time being i will run with no power(cant afford controller at the present time!).i am doing a rally at abingdon on june 10th,with work and other things going on i think run as is.
cheers neal

 

FWIW:
I wish I had stuck to my gut feelings and bought a Neetronics unit instead of the Subaru parts, time wise much cheaper and less frustrating option.

I know someone with 2 controllers and he has just installed the Neetronics to good effect (a hillclimber).

Erm... who would that be ?

 

Dunno, some fast Scottish guy.

Did all your programming work out John?

Neal,
Take the car for a thrash to get the feel of it, if you run the diff open, I've just done the same in my rally car and to say the first stage was a voyage of discovery was an understatement. Rubbish stage times but great fun, till number 3 rod decided to make a bid for freedom 6 corners from the end of the rally. API to the rescue new engine should be on it's way soon.

One question for you all if anyone knows I'm fitting a dif controller from rallispec that a family member brought over last week on the wiring diagram i states that I should have a black and dark green wire from the box, I seem to have 2 black wires, does it matter which way I connect them up to the wiring loom or is there any way to chech which way round they go?

Thanks
Huw

 

There should be indeed a black and green wire!
My Type R box was so (V6) so look closer as Dark = black almost..

 

pretty sure it doesnt matter which way round the wires go from the dccd controller to the box.

Try this diagram.
I used it and all worked well.
