Stage 1 remapping in Tadworth and Epsom Downs
Two or more cars were kept by 54% of households in the Tadworth and Epsom Downs built-up area at the 2021 Census, against 35.4% across England and Wales. Only 9.1% had no car at all. Where a household has a choice of cars, the one that covers most of the miles is usually the one to look at for Stage 1 remapping. The work is a software change to fuel, boost and timing, kept within the engine's limits and with nothing bolted on. On a diesel it adds torque in the mid-range, so the car pulls more readily from low revs, needs fewer downshifts and copes better with a full load.
