Stage 1 remapping in Chippenham
Just 15.5% of households in the Chippenham built-up area had no car in the 2021 Census, well under the England and Wales figure of 23.3%, while 42% had two or more. When there is more than one car on the drive, it makes sense to look first at the one covering the motorway miles or doing the towing. Stage 1 remapping changes only the engine software: fuel, boost and timing are adjusted within the limits the engine was built to, and no parts are added. What you notice on a diesel is torque in the middle of the rev range, so the car holds a gear longer on a climb and passes slower traffic with less effort.
