Stage 1 remapping in Durham
The A1(M) is on Durham's road list, along with the A690, A691, A167, A177, A181 and A688, so faster roads are within easy reach of DH1. Out on those roads, a Stage 1 remap shows itself with a full car: passengers and luggage on board, and the diesel still pulls without a string of downshifts. Only the engine's software settings for fuel, boost and timing are revised, within the engine's limits, and no parts are fitted. The extra torque sits in the mid-range, which is where overtaking happens. Insurers have to be told about a remap.
