Default Needing some help

Ok I am very much a noob to the scooby world but I am learning. I have done a lot of searching and have not been able to find the answer to the question I have so please do no flam me too bad. I have a 02 wrx that busted a cam gear and suffered a engine failure we are unsure of what caused the gear to break but the engine was seized up. I attempted to find a USDM motor for a reasonable price and was unable to do so. I then purchased a jdm motor (Ej205 with avcs) I understand I will not be able to use the avcs function with out a jdm ecu which I am on the hunt for. I have found a complete donor 04 Sti that I would like to install the 6speed and the dccd function but I have read that that this is also wired in the sti ecu. My question is this if I use the USDM ecu from the sti will I be able to use the avcs of the jdm motor I have and the dccd? What is the best way to get the function of the dccd and the avcs? Thank you in advanced for all your input and advice I appreciate it more than words can describe.

Quick answer just off the top of my head here.

The JDM engines use different cam position sensors than the USDM engines (cams are actually different as well), so I'd say that even if you used the full USDM ECU, you may still run into calibration issues with the JDM engine.

Also, for the DCCD, there is a separate DCCD ECU that is the brain of that system, and it also talks to the ECU and gets data from different sensors through out the car (ABS I believe and a couple of others).

So the short answer is that it is not going to be a simple plug and play swap for either function FWIW.

Check out DCCD Pro for the DCCD function.

Good luck with the project!
