WRX MY16 — Stage 2 ECU Tune
- Optimized engine control parameters
- Enhanced turbocharger efficiency
- Improved throttle response
- Refined fuel injection mapping
- Increased power delivery
This MY16 WRX went through a Stage 2 calibration to suit basic supporting hardware. Workshop dyno figures came back at 114 kW at the wheels, up 6 kW from the 108 kW baseline, with torque lifting from 285 Nm to 290 Nm.
The numbers suggest a cautious approach, likely prioritising reliability over peak output. These FA20DIT cars respond well to tuning when supported properly, but this file kept things modest. Could be the owner wanted daily drivability maintained, or the hardware didn't leave much room to move.
Stage 2 on these platforms typically means an exhaust and intake at minimum. The torque curve would have smoothed out even if the headline figures stayed conservative. Useful for a car that still sees commuter duties on 98 RON.
Why are the power gains so small for a Stage 2 tune?
The 6 kW gain suggests either conservative tuning for reliability, limited supporting hardware, or a baseline that was already fairly healthy. Without knowing the specific mods or fuel type, it's hard to say where the ceiling was.
Is this file suitable for a MY16 WRX with similar mods?
Only if the hardware matches exactly and the car has been properly assessed on a dyno. Every FA20DIT responds a bit differently depending on condition, fuel quality, and specific parts fitted.
