Genuine Plug-In convenience with modern G4X architecture, advanced tuning and motorsport features.

Purpose-built for the WRX Version 3-4 the WRX4X is designed to fit directly into the factory ECU location using the factory mounts, original wiring loom and connectors. No rewiring, no adapter looms, no compromises. It retains all factory functionality, delivers seamless OEM integration and includes a startup map to get your vehicle running quickly. The result is a clean, simple, reliable installation that maintains a stock appearance.

Features include dual CAN Bus, Flex Fuel, Flexible Engine Protection Limiters, CAN Keypad Control, Open and Closed Loop Boost Control, Dual Closed Loop Lambda, VVT Control, a built-in Trigger Oscilloscope, compatibility with aftermarket displays, Direct Automatic Transmission Control and 512MB of onboard data logging.

Drawing from Link's championship-winning G4X platform, the WRX4X also supports advanced tuning and motorsport features including Nitrous Control, Launch Control, Anti-lag, Cruise Control, Traction Control, Race Timer and Power Management, Gear Shift Control and Paddle Shift Control.

A Link Plug-in ECU is the ideal solution when available for your vehicle and the wiring remains in good condition, providing modern engine management without the complexity of a wire-in installation.
