QR25DE SpecV ECU

The 2J Racing ECU is a used and tested engine control unit for the Nissan Sentra 2.5L QR25DE SpecV. It is available for model years 2002-2006. The ECU can be ordered in stock form or reflashed with an UpRev tune, which can disable NATS (Nissan Anti-Theft System) and/or add a performance tune for non-turbo applications.

If your vehicle is equipped with NATS (identified by P8, GU, or R5 ECU codes), the ECU will not function unless the dealer codes the key to the new unit or the UpRev flash option is selected to disable the security system. All ECUs are tested prior to shipment, and returns are not accepted.
