About remapping
This entry groups BMW three-door units recorded under this body designation, with 35 files in our catalogue. All are diesel: the 1.5D three-cylinder and the 2.0d, including the higher-output SD versions.
Stage 1 makes up all 35 files — the purest performance profile in our BMW catalogue. The ECUs are EDC17C50 and EDC17C41, a small and consistent set that simplifies identification considerably.
