Installation and coding

After fitting, the injector calibration values must be programmed to the ECU by a BMW-capable technician. For best results replace as a complete set by cylinder count. On B58 straight-six we recommend all six at the same time. On B38 three-cylinder and B46 B48 four-cylinder engines we recommend a full matched set.
