S60 1.6 D2 Siemens SID807 VRCA1H0000000 — ECU Firmware Stage 1  - Copyright info

Factory mapping on Volvo’s 2015 S60 1.6 D2 (SID807) favours low-NOx emissions and clutch longevity, so pedal response feels muted and sustained boost is capped. This Stage 1 firmware readjusts the driver-wish surfaces, torque monitors and rail-pressure ramps for a quicker correlation between right-foot input and delivered torque, while turbo duty is lifted inside the OEM exhaust-temperature envelope to maintain component safety. Injection-timing advance is applied only in the mid-range; cold-start, idle and altitude compensations remain stock for smooth daily refinement. EGR flow is reduced and its diagnostics balanced to keep the intake cleaner without triggering DTCs. All knock, misfire, DPF and sensor-plausibility routines stay active, ensuring the ECU still intervenes if mechanical limits are approached. The result is a keener surge through common motorway revs and a more confident pull in higher gears, achieved with zero hardware changes and full emissions self-check integrity.
