USED JDM Subaru Legacy EZ30 Engine Control Unit ECU – OEM Part #22611AE972 / 112000-7304

Restore factory engine management and reliable performance with this used JDM OEM Subaru Engine Control Unit (ECU), part number 22611AE972 (manufacturer reference 112000-7304), designed for Subaru Legacy models equipped with the EZ30 3.0L H6 engine. Imported directly from Japan and sold by J-Spec Auto Sports Inc., this ECU is the correct factory computer for early EZ30 applications and is becoming increasingly difficult to source.

This OEM Subaru ECU is programmed with original factory calibration to properly manage fuel delivery, ignition timing, and engine operation for the naturally aspirated EZ30 flat-six engine. Using the correct ECU is critical on H6 Subaru platforms, as mismatched or aftermarket computers often result in poor drivability, check-engine lights, or improper engine performance.

JDM ECUs are highly sought after due to their origin from low-mileage Japanese vehicles, where strict inspection laws often preserve electronic components in better condition than many U.S.-market alternatives. This ECU has been tested and verified for functionality, ensuring it is a genuine Subaru unit and ready for installation when paired with the correct wiring harness and engine setup.

Whether you’re replacing a failed ECU, completing a JDM EZ30 engine swap, or restoring a Subaru Legacy to OEM-correct configuration, this engine computer provides a reliable and cost-effective solution without the risks of reflashed or cloned units.
