Stage 1 remapping in Cwmbrân
Three neighbouring towns lie within 7.6 km of Cwmbrân: Pontypool at 4.7 km, Risca at 7.5 km and Newport at 7.6 km. Short runs with frequent stops keep a diesel in the low and middle revs, and it is in that band that Stage 1 remapping makes itself felt. The remap is a software change to fuel, boost and timing, kept within the engine's limits, and nothing is bolted on. More mid-range torque means the car or van picks up speed from junctions with less effort and holds a higher gear for longer, which makes town driving smoother. If the vehicle carries tools or tows at weekends, the difference is clearer still.
