So I've got a DCCD box out of a 2008 STI and would like to be able to use the adjustable diff if possible. Firstly the electrical side, not sure they ever fitted DCCD to a V1/2 Impreza so am I likely to find a loom to fit or mechanical speedo clocks with the diff lights?
Secondly, I am running a standard R180 rear diff. Pretty sure this should be fine with the DCCD box but have heard talk of a sensor that needs to be connected to it, could someone clarify please? Cheers

 

I believe your final drive is different which means you need the matching rear diff for the gearbox, yours being a 4.111 and the sti having a 3.900.
Then you need a controller for the dccd, neetroniks? do one though you may need some additional wiring/loom.

 

The rear diff is a 3.900 from a STI 7 non DCCD, I take it that makes no difference then Tony? Yeah looking at it aftermarket controller is the way forward, will scour the net and see what sort of money they are.

 

Neetronics is by far the best one to use.

 

Yeah have been looking at the Neetronics but its £580! That's more than I originally paid for my WRX!(owes me more like 10k now but not the point!)
Is the DCCDPRO no good then? seems to do everything needed including locking the diff whilst launching but for half the price.
From what I've read running the box without any controller will make it almost rear wheel drive and wont work on most dynos so definitely need to get it sorted.
