Listing an 2007 Subaru STI ECM/Immobilizer(CJ) my coworker/accomplice just pulled out. Works fine! I assume it will work with that entire range/body style STI. If anyone is wondering, though, I will check with parts to find out for sure.
This ECU was replaced in a car for no reason, because the ECU is in perfect working condition.
