So I'm looking at buying a 2002 WRX with an 05 STI engine swap. The seller says that the transmission has dccd, but the controller isn't hooked up or something. Im confused as to whether thats even possible and if so what bias does the transmission have then? If anyone has any knowledge on this and can give me some information I'd greatly appreciate it. The rest of the build seems pretty good other than having no boost solenoid or controller(apparently the shop just went straight to the wastegate and it pushes 22psi), but that should be easy to implement.

Thank you.
