V40 2.0 D3 BOSCH EDC17_CP48 545298 — ECU Tuning Binary Stage 1  U102B

Volvo’s Euro-5 V40 2.0 D3 is factory-calibrated for exemplary emissions and clutch longevity, which leaves its Bosch EDC17_CP48 control logic with deliberately gentle driver-wish surfaces, conservative turbo duty maps and relaxed rail-pressure ramps. This Stage 1 firmware narrows those margins: pedal demand curves and torque limiters are rescaled for a crisper, more proportional response; turbo boost request is elevated inside OEM exhaust-temperature guard rails; and injection timing is advanced only through the mid-band to sharpen pick-up without disturbing cold-start, idle or altitude behaviours. EGR flow is trimmed and its diagnostics re-balanced, keeping fault monitors quiet while maintaining a cleaner intake charge over long mileage. All DPF, sensor-plausibility and limp-home routines remain active, so the ECU will still intervene if mechanical or thermal thresholds are approached. The result is noticeably quicker spool, a firmer surge between 1 700-3 500 rpm and more relaxed motorway cruising—delivered with zero hardware changes and full emissions self-check integrity.

All tuning files were acquired through official EVC.de resellers and verified on a professional dynamometer. Each calibration corresponds to the developer listed in the “Modified By” section — performance graphs may be available on their official website.
