Stage 1 remapping in Havering
Every London borough sits inside the Ultra Low Emission Zone, Havering included, and Havering is the easternmost of them. The M25, which is among Havering's main roads, is not part of the zone. If you are weighing up a Stage 1 remap here, the ULEZ point is simple: a remap does not change a vehicle's emissions standard, so it does not change whether the zone's daily charge applies to your car or van. What it does change is how the engine delivers its power. The fuel, boost and timing settings are adjusted in software, within the engine's limits, and on a diesel the gain you feel most is mid-range pull for overtaking and joining faster roads.
