WRX — Stage 1 ECU Tune
- 32% power increase
- 28% torque increase
- Improved fuel efficiency
- Enhanced boost control
- Optimized fuel delivery
This 2012 WRX file extracts a genuine 50 kW gain at the wheels without hardware changes, landing at 207 kW on the stock factory ECU. Torque sits at 300 Nm, controlled and usable throughout daily driving while pushing 1.3 bar of boost for closed-circuit work.
The calibration leans on factory injectors and high-pressure fuel pump paired with dialled wastegate solenoid control and drive-by-wire mapping. It's a straightforward Stage 1 package on 98 RON that gives your customer a noticeable step up without the complexity or expense of supporting mods.
Suited to weekend competition use where the extra 50 kW makes a difference without crossing into territory that demands clutch, intercooler, or fuel system work. Clean result from a platform that responds well when the boost and fuel tables are opened up properly.
Does this file require any hardware changes to the car?
No. This is a Stage 1 software-only calibration. The customer can run it on the existing factory setup with 98 RON pump fuel.
What boost pressure does the tune run?
The file is mapped to 1.3 bar, controlled through wastegate solenoid calibration on the factory ECU.
Is the torque gain modest compared to the power increase?
Yes. Torque lifts from 295 to 300 Nm—only 5 Nm—while power jumps 50 kW. The EJ25 responds more dramatically in the top end when boost and timing are optimised for 98 RON.
