Default How to Use 04 Sti DCCD with GC8?

So I just bought my STi set up w/ Complete wiring harness, intercooler, airbox, intake, fuel pump, shifter hardware, fuel level sender, fuel controller, ECU, DCCD control unit, radiator, gas petal with TPS, all associated switches relays, fuse box's everything. Complete rear end. YAY!

Iím a little confused about using the DCCD with my 98RS. Since I have the complete harness and switches from the sti, I would assume I have everything required to fit in my car. I have heard there is a complication with using the DCCD with older ABS unit?? Re-wiring of brakes? Will they work with my stock braking system? Iím a n00b with this type of electrical stuff so all suggestions or directions to find info is greatly appreciated.

You will need dccd g-sensors and mor! Go to the www.Rocketrally.com he has some very cool DCCD ECUs that are easy to install for a great price! It will save you loads of hassle!

I am getting the complete gauge cluster, switch harness, knob, ecu, and sensors. I just want to make sure thereís no little things to worry about. Anything required besides hooking up the harness to the tranny, and g-sensors? Since it is monitoring my acceleration/braking is there any issues using my ABS system?

I believe you will need the STI ABS system and control unit which sends signals to the DCCD to to provide input for the auto option. I am hooking mine up without the auto option for the time being, but I am keeping all the wiring and sensors in case I want to swap to all STI hubs, ABS system and auto option in the future.

I talked with wrx_driver_2002 about some of the swaps he has performed, and he has kept auto in a Forester, but said it was a bunch of work.

I have my hands full with the engine, tranny, cluster for the time being. If you go for it good luck, it is achievable!

EDIT:

The STI ABS controller is integrated into the pump. I believe it's all or nothing.

I dont have AbS on my GL, so i think i can forget about the auto version and it will have to stay on manual all the time?
Hopefully i can get it working.

PS
mjd85la, i almost have the same project, but i think you have more components then me, are you going to put up a thread on your project too?

greets

It was alot of work to make the system work. The FXT that we did the 6mt swap in will be featured in Subiesport in the next issue, I believe. It required using the STI Abs Pump, removing the stock porportioning valve (Because the STI porportions electronically through the abs pump instead of mechanically through the porportioning valve) and adding the STI Coupler (on the right front strut tower) Rewiring the ABS System, Rewiring the dash for the STI Cluster, and lengthening all of the wires for the switches / sensors. We had to mount them a little bit different locations. I have pictures of the build process if anyone is interested. We ended up putting the Auto / Manual Switch and the Adjustment Knob in the location where the seat heater switches were in the center colsole. we moved the seat heaters to each side of the center console about where your calf sits when you're in the seat.

Adding the Auto mode on the WRX would be the exact same amount of work we had to do to the forester. IT's about as much splicing as an engine swap.

Here's the thread for the Forester:
