Swift — Stage 2 ECU Tune
- Improved Power Output
- Improved Torque Delivery
- Enhanced Boost Control
- Optimized Fuel System Performance
- Drive By Wire Calibration
This 2017 Swift on 98 RON picks up 10 kW at the wheels with a Stage 2 file built around upgraded injectors and high-pressure fuel pump to support revised boost control and drive-by-wire mapping. Factory ECU, but not a factory fuel system.
The torque figure of 426 Nm looks unusual for a small-capacityturbo hatch and likely reflects dyno measurement method rather than raw engine output—always cross-reference with your workshop's preferred dyno and load conditions. The file addresses fuelling, boost delivery via wastegate solenoid control, and throttle response through DBW calibration.
Suited to closed-circuit or off-road competition use where the supporting hardware is properly sorted. The K14C responds well to fuel system upgrades when you're chasing more than a basic Stage 1 flash can safely deliver on stock injectors.
Why is the torque figure so high for a 1.4-litre engine?
The 426 Nm reading is likely a product of the dyno's measurement method or gearing multiplication. It's not crank torque in the traditional sense. Always baseline your own dyno to confirm real-world output.
What fuel system changes are needed for this Stage 2 file?
This calibration requires upgraded injectors and a high-pressure fuel pump to support the revised boost and fuelling maps. Factory injectors won't hold the duty cycle safely on 98 RON at this output level.
Is this file suitable for street use?
It's intended for off-road and closed-circuit competition. The supporting mods and revised boost control push beyond factory design limits.
