Built around Honda’s 2.2-litre i-DTEC, this Stage 1 file targets a wider, more elastic torque band for daily driving and towing alike. DPF regeneration logic and EGR flow are fully disabled, freeing the exhaust path and keeping intake charge clean. Torque, boost and smoke limiters are rescaled with balanced AFR to protect the stock clutch while adding urgency from 1 700 rpm. Cold-start, idle and part-throttle maps are refined to retain OEM fuel efficiency on cruise, yet deliver earlier boost and crisper throttle response under load.
