Stage 1 remapping in Bishop's Stortford
Just 2.3 km separates Bishop's Stortford from Welcome Break Birchanger Green Services on the M11, so the motorway starts almost on the doorstep. Longer commutes were also more common than average: in the 2021 Census, 7.6% of working residents in the Bishop's Stortford built-up area travelled 30 km or more to work, against 4.4% across England and Wales, and that was on a census day in lockdown. For drivers who spend time on the M11, Stage 1 remapping changes the engine's fuel, boost and timing settings in software, within its limits. On a diesel the gain is torque in the middle of the rev range, so pulling out to pass a lorry or merging from a slip road needs fewer downshifts.
