Stage 1 remapping in Bushey
Bushey recorded relatively few households without a car at the 2021 Census: 12.6% in the Bushey built-up area, against 15.5% across the Hertsmere council area and 23.3% in England and Wales. At the other end, 44.3% of households had two or more cars, well above the England and Wales figure of 35.4%. With a car on nearly every drive, the questions people ask about Stage 1 remapping are practical ones: what changes, and what does not. Only the software does. The engine's fuel, boost and timing settings are adjusted within its limits, and no parts are added. On a diesel you feel stronger mid-range torque when pulling out onto the M1. A car with an EGR or injector fault is repaired before it is remapped.
