Suzuki Swift Sport 1.6i 16V Stage 1 (125PS / 5M) - Reviews

Factory mapping for the 2008 Suzuki Swift Sport’s high-revving 1.6-litre M16A engine is deliberately conservative: ignition advance is pulled back around peak volumetric-efficiency, throttle and torque limits cap the mid-range, and fuel-enrichment strategies prioritise emissions over crisp response. This Stage 1 Denso N2E62M00 calibration re-profiles the driver-demand, torque monitoring and electronic throttle tables for a more linear pedal feel, then carefully extends load axes on the ignition and VANOS cam-overlap maps to unlock cleaner cylinder filling above 4 000 rpm while retaining safe knock-control headroom. Fuel-delivery targets are smoothed for a steadier lambda trace under transient loads, catalytic-converter temperature protections remain active, and all OEM diagnostics—including misfire, O2-sensor and CAN plausibility routines—stay enabled to safeguard reliability. Cold-start and altitude corrections are preserved, so day-to-day drivability and start-up manners stay strictly stock; the car simply breathes more freely and responds more promptly throughout the rev range.
