Diesel Mercedes S-class: what changes with a remap

Modern diesels are held back by conservative factory calibrations. A remap updates the fuel and boost maps stored in the ECU, which is why drivers notice stronger acceleration from low revs and less need to change down on hills or when loaded.

For reference, CDI is the Mercedes-Benz name for its common-rail diesel engines.
