Stage 1 remapping in Ewell
Set against the rest of the Epsom and Ewell council area, the Ewell built-up area leans harder on the car. In the 2021 Census, 39.3% of its working residents drove to work, compared with 34.2% across the council area, though that was still under the 45.1% for England and Wales. Those figures were collected during a lockdown, when commuting was lower than usual. If your car covers most of your journeys, Stage 1 remapping is a way to make it more relaxed to drive. The software change covers fuel, boost and timing, all within the engine's limits. On a diesel or a turbo petrol, the gain shows as mid-range torque, which helps when joining faster roads.
