Default Jdm Ecu

I try to put a jdm V7 ecu in my 2002 wrx (EDM) but i dont have any signal of the ecu .
I put again my car ecu and itīs ok.
I put the jdm ecu and i found the two conectors of the power supply the reading is 0V and when the factory ecu is connected the two wires have 12V.
Itīs the immo or another problem.

Your WRX doesn't have AVCS, the V7 STI does. Won't work.
