How ECU remapping works on a diesel Audi A4

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, TDI is the Volkswagen Group name for its turbocharged direct-injection diesel engines.
