ProAce 1.6 D-4D BOSCH EDC17C60 021971 — ECU Tuning File Stage 1  - Product specifications

Toyota set the 2018 ProAce 1.6 D-4D’s Bosch EDC17C60 calibration up for fleet-grade durability, which results in a deliberately gentle throttle map, modest boost demand and relaxed rail-pressure ramps. This Stage 1 file tightens those areas while preserving every factory safeguard: driver-wish and torque-limiter axes are rescaled for a more immediate response; turbo duty is raised inside the OEM exhaust-temperature envelope; and injection timing is advanced only in the mid-band so idle refinement, cold-start manners and altitude corrections stay stock. EGR flow is reduced with diagnostics re-balanced to prevent DTCs, keeping the intake cleaner over high mileage. All sensor-plausibility checks, limp-home pathways and catalyst-temperature monitors remain active, so the ECU still intervenes if mechanical limits are approached. The result is a van that pulls more confidently through everyday gears, handles motorway gradients with less downshifting and retains the emissions self-check integrity demanded by professional operators—all without hardware changes.
