it came off of my 2003 wrx . its tuned for VF34, sti pinks, up-pipe, turboback and fmic . I dont need a stock ECU in return . So no downtime for either buyer or seller . Let me tell you from first hand experience , this engine management is literally 3 times better than COBB AP and its a conservative tune . Very impressive & big a*s difference .
