Stage 1 remapping in Bridgend
Sarn Park services on the M4 is just 2.9 km from Bridgend, so the motorway is part of ordinary driving here rather than an occasional trip. The town also sits halfway between Cardiff and Swansea, 32 km from each, which puts both cities within easy reach. A mix of short local trips and steady M4 miles is where Stage 1 remapping on a diesel earns its place. The work is a software change to fuel, boost and timing, kept within what the engine was designed for, with no hardware added. What changes is the mid-range: joining from a slip road takes less effort, and overtaking at motorway speed needs fewer downshifts.
