Transit 2.2 TDCI Siemens SID208 FRQ61C4000000 / SW-DS-PBK21-12A650-BAB — ECU Firmware Stage 1  - Product specifications

Factory mapping on the 2015 Ford Transit 2.2 TDCi leaves generous safety head-room: the driver-wish surface is flattened to protect clutches, turbo duty is capped to keep EGTs low under heavy payloads, and rail-pressure ramps are tuned for smooth fleet drivability. This Stage 1 calibration for the Siemens/Continental SID208 controller re-profiles those areas without touching cold-start or altitude strategies. Pedal input now translates into torque more directly; boost demand is lifted inside the OEM temperature guard-rails; and injection timing sees a modest mid-band advance so the van pulls with less down-shift on inclines. EGR flow is trimmed and diagnostics re-balanced, slowing soot build-up without triggering DTCs, while every DPF, sensor-plausibility and limp-home routine remains active. The result is crisper throttle response, stronger mid-range haul and easier motorway cruising — all with stock hardware and full emissions self-check integrity.
