Stage 1 remapping in Darwen
Darwen sits just 1.9 km from ExtraMSA Blackburn with Darwen Services on the M65, and the A666 links the town with Blackburn, 5.6 km away. That puts a motorway within a short drive. For a car or van that regularly joins the M65, Stage 1 remapping is felt where it counts. It changes the engine's fuel, boost and timing settings in software, within the engine's limits, and on a diesel it brings more mid-range torque, so the vehicle gets up to motorway speed with less effort and overtakes more cleanly. A vehicle with a DPF or AdBlue fault is repaired before any remap, so the engine is healthy first.
