X-Trail 2.0 DCI BOSCH EDC16CP33 500066 / SW-394500 — ECU Firmware Stage 1  - Copyright info

Although the 2009 Nissan X-Trail 2.0 dCi already feels lively, its factory Bosch EDC16CP33 calibration is set up with generous safety margins that leave close to 40 Nm of untapped torque on the table. This Stage 1 binary reshapes the main torque model, driver-wish and smoke limiters, lifts turbo duty ceilings and re-aligns rail-pressure targets to exploit that reserve without breaching EGT limits. Mid-range punch improves markedly, giving crisper throttle response and quicker overtakes, yet fuel economy in steady-state cruising remains unchanged thanks to refined partial-load injection timing. Cold-start and altitude compensations are preserved, and all diagnostic trouble-code paths as well as limp-home strategies stay active, so drivetrain safety is never compromised. Designed for six-speed manual gearboxes, clutch-torque monitors are adjusted to stay inside stock hardware capacity, ensuring long-term reliability. The file flashes through any EVC-compatible tool in minutes and is intended for engines running stock turbo, intercooler and exhaust after-treatment; no mechanical upgrades are required. With the calibration loaded the X-Trail pulls harder from 1 700 rpm, holds power to 4 300 rpm and delivers an estimated 190 hp while retaining the smooth drivability expected from a family SUV.
