Genuine OEM Subaru Engine Control Unit (EGI Control Unit Assembly) – Part #22611AD730 – EJ20G (1997–1998)

The Subaru 22611AD730 is a genuine OEM Engine Control Unit (EGI Control Unit Assembly) engineered by Subaru for select models equipped with the EJ20G turbocharged engine, produced between April 1997 and July 1998. This factory ECU is a critical component for maintaining correct engine operation, drivability, and reliability on late-1990s EJ20G platforms.

Designed and calibrated by Subaru, this ECU manages fuel delivery, ignition timing, boost control, and sensor communication exactly as intended for the EJ20G engine. Using the correct OEM ECU is essential on these engines, as mismatched or aftermarket ECUs often lead to check-engine lights, drivability issues, improper fueling, or boost irregularities.

The 22611AD730 ECU is commonly required for JDM engine swaps, ECU replacement, or OEM-correct restorations, especially on vehicles originally built within the 1997–1998 production window. EJ20G ECUs are increasingly difficult to source due to age and limited production, making genuine OEM units like this one highly desirable among Subaru enthusiasts and professional installers.

When paired with the proper wiring harness, sensors, and drivetrain configuration, this ECU ensures stable idle, smooth acceleration, and factory-correct turbo performance. It is the correct solution for customers who want reliability and originality rather than reflashed or modified alternatives.
