Stage 1 calibration for Opel Meriva 1.4 Turbo — ECU 55580973, prod 55580970 — quicker boost build-up and sharper throttle without extra stress.
Applied here, Stage 1 mapping widens the 1.4-litre turbo’s torque window while keeping OEM smoothness. Knock-adapted ignition tables, lifted boost/load limiters and a slightly sharper throttle curve give crisper low-gear response, yet cruising fuel economy remains stock. Vmax restriction is removed; cat-diagnostics and all OBD monitors stay active for MOT readiness. Cold-start, idle and part-throttle zones are retuned so drivability in daily traffic feels factory-refined despite the added urgency.
