Grand Vitara 1.9 DDiS BOSCH EDC16C36 503108 — ECU File Stage 1  503108

Suzuki’s 1.9-litre DDiS turbodiesel in the 2011 Grand Vitara leaves a generous safety buffer in its stock Bosch EDC16C36 calibration, sacrificing punch for emissions margin and drivetrain longevity. By carefully remapping the main torque model, driver-wish, boost duty and smoke limit tables, this Stage 1 file liberates roughly 35 Nm and 28 hp without breaching conservative exhaust-gas-temperature targets. Rail-pressure set-points are raised in transient zones for a quicker ramp-up in injection quantity, then tapered at steady-cruise loads to keep fuel economy unchanged. Injection timing advance is optimised between 1 800–3 200 rpm, improving cylinder pressure phasing and mid-range efficiency, while altitude and cold-start corrections stay intact for OEM-grade reliability in extreme climates. EGR flow is reduced but diagnostics preserved to prevent fault codes, and all factory limp-home strategies remain active to protect against sensor failure. The result is a noticeably stronger surge from just under 1 700 rpm, a broader plateau of pulling power through 4 200 rpm and more confident overtakes, yet the calm drivability and refinement of the commuter-friendly SUV are fully retained. Supplied as a complete binary that flashes in minutes via any BDM/OBD tool supporting Bosch EDC16V2, the calibration is designed for engines running stock turbo, injectors, clutch and DPF, so no hardware upgrades or irreversible modifications are required.

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. These files are intended for motorsport or off-road use only. Ensure proper installation and do not operate the vehicle aggressively without first confirming mechanical condition.
