Ford Focus 1.5 STCI — Bosch MG1CS016 Firmware KX7A15C204-AGE Stage 2  CDMS3Z7

Elevate your 2019 Ford Focus 1.5 STCI to a new level of performance with this meticulously engineered Stage 2 calibration file. Building on factory safety maps, the remap unleashes significant gains across the powerband without compromising drivability or component longevity. The turbocharger boost curve is reshaped with precision to deliver instantaneous spool and a sustained surge of torque from just 1,800 RPM up to redline, transforming everyday driving into a truly engaging experience. Fuel injection quantity and timing tables are comprehensively rewritten to optimize atomization and combustion efficiency under varied load and temperature conditions, resulting in smoother mid-range thrust and a crisper throttle feel with no flat spots. Advanced boost pressure and torque protections are carefully raised within OEM safety margins, delivering an extra 30–35 Nm of torque and a 15–20% increase in peak power, ideal for confident overtakes and spirited highway passing.

Secondary systems are fine-tuned to ensure reliability: EGR flow parameters are recalibrated to minimize soot buildup while maintaining emissions compliance, and DPF regeneration thresholds are extended to improve filter life during mixed driving cycles. Cold-start enrichment, idle stability, and deceleration maps are enhanced to guarantee smooth startups in all climates and a stable idle in stop-and-go traffic. Additionally, the 6-speed manual gearbox adaptation tables are retuned to harmonize shift points with the enhanced torque curve, resulting in crisp, precise shifts and reduced shift shock under load. All calibration data undergoes full checksum correction and is formatted for seamless flashing via CMD Flash or any bench/OBD tool compatible with Bosch MG1CS016 ECUs. Whether navigating urban streets or exploring winding backroads, this Stage 2 map delivers a perfectly balanced blend of performance, refinement, and drivability that redefines the driving character of your Focus without compromise.
