How ECU tuning works on a petrol Smart Roadster
On a petrol car the ECU controls fuelling, spark timing and any turbo boost. A remap re-calibrates those maps within safe limits, so the car responds more eagerly and pulls harder through the rev range.

Ranked by power gain against the other petrol Roadster engines (2 in total), the 61 is 1st, 1 bhp above the Roadster petrol average of 21 bhp.
