WRXLink G4X PlugIn ECU for WRX V10 EJ25 2.5L

The Link ECU WRXLink is a G4X PlugIn ECU engineered to easily maximize the potential of your WRX V10 EJ25 engine, covering 2.5L models from 2004 to 2007. Featuring a 150 MHz microprocessor, this ECU provides advanced engine management capabilities. It offers precise control with ignition timing adjustable to 0.1 degrees and fuel delivery adjustable to 0.01 ms, utilizing a 32-bit floating-point calculation and a 12-bit ADC resolution. Key features include up to 6D fuel and ignition mapping, sequential fuel delivery, digital triggering for all OEM patterns, and OEM idle hardware support. It also includes advanced motorsport features such as antilag, launch control, and flat shifting, along with continuous barometric correction via an onboard sensor. The ECU supports individual cylinder correction, USB tuning cable, stats recording into on-board memory, and gear compensations for spark, boost, and fuel. Compatibility is specific: this WRX107X model is intended for the GD or GG chassis with electronic throttle and manual transmissions only. It is not suitable for GR/GH/GE/GV hatchback or 3rd generation WRX's. To determine the correct ECU, check pins A1-3: if they have wires, the WRX104X is needed; if they are unpopulated, the WRX107X (this model) is required. Some 2006 models may require this WRX107X even though the WRX104X generally covers 2004-2006. An air temp sensor is highly recommended for optimal performance, and most factory features are supported. Expansion options are available, with specific inputs/outputs depending on whether it's a 2004-2006 ECU (which has a blank expansion connector) or a 2006-2007 ECU (which includes an 8-pin expansion connector with various auxiliary inputs/outputs and digital inputs).
