Opel Insignia 2.0 CDTI A20DTE EDC17C59 ECU Calibration File | Software 543039 / SW B12024 | Stage 1  - Releases

The calibration applies **Stage 1** logic to the 2.0 CDTI A20DTE, targeting an earlier boost rise and steadier pull through mid-range gears. DPF regeneration routines and EGR flow are fully disabled, reducing back-pressure and keeping the intake charge clean. Torque, boost and smoke limiters are rescaled with balanced air-fuel targets so the six-speed gearbox remains within OEM load margins. Cold-start, idle and part-throttle maps are refined to preserve factory fuel economy on cruise while delivering crisper urban response.
