Stage 1 remapping in Billericay
In the 2021 Census, 38.3% of working residents in the Billericay built-up area drove to work, below the England and Wales figure of 45.1%. That was not for lack of cars: only 11.5% of households had none, against 23.3% across England and Wales, and 46.1% had two or more. Census day also fell in a lockdown, so the commuting share is a snapshot of an unusual day. Whatever a Billericay car is used for, Stage 1 remapping works the same way: the fuel, boost and timing settings are adjusted in software, within the engine's limits, and nothing is bolted on. On a diesel you feel it as mid-range torque, so the car pulls from low revs without hunting for a lower gear.
