Smart remapping at Regal Tuning
Verified gains, engine by engine
Every Smart calibration in this database is software-only Stage 1 upwards: no hardware changes, fully reversible, and developed against the specific engine variant rather than a generic map. Each vehicle page lists the exact factory output alongside the tuned figures for that engine and generation.
Figures depend on vehicle health, fuel quality and conditions — we confirm the expected output for your specific vehicle in writing before any work begins. If your exact variant isn't listed, ask us: coverage expands continuously.
How to get your Smart remapped
From quote to tuned in days
Request a quote with your vehicle details or registration and our calibration team will confirm support and expected gains. Existing customers upload their ECU file through the Regal Tuning file portal with full technical support and the original factory file always kept on record.
