Ford Focus Mk4 1.5 T Ecoboost — Bosch MG1CS017 Calibration File JX6A-14C204-EBD Stage 1  14C204

Elevate your 2020 Ford Focus Mk4 1.5 T Ecoboost with a comprehensive Stage 1 calibration that strikes the ideal balance between everyday drivability and spirited performance. Beginning with a bespoke turbocharger boost strategy, the map dramatically reduces lag, delivering a crisp surge of torque from only 1 500 RPM through to peak power. Injection timing and quantity tables have been meticulously re-engineered to optimize fuel atomization across the rev range—this results in a beautifully linear power delivery curve, eliminating flat spots and smoothing throttle transitions, whether crawling through city traffic or accelerating onto the highway.

Advanced torque and boost limiters are recalibrated within OEM safety margins to unlock an extra 30 Nm of mid-range torque without compromising component longevity. Secondary systems are also refined: EGR flow parameters are adjusted to minimize soot buildup in the intake manifold, while DPF regeneration thresholds are extended to improve filter life under mixed driving cycles. Cold-start and idle stability maps have been enhanced to ensure smooth, stall-free startups in all temperatures, preventing rough idles and hesitations during stop-and-go conditions. Transmission adaptation tables for the automatic gearbox are fine-tuned to match the enhanced torque curve, providing seamless, confidence-inspiring shifts under load.

All calibration data undergoes full checksum correction for seamless flashing via Autotuner OBD or any bench/OBD tool compatible with Bosch MG1CS017 ECUs. The result is a thoroughly optimized driving experience—combining refined street manners with a pronounced performance uplift—without sacrificing reliability, efficiency, or comfort.
