BMW X3

BMW X3 tuning files

Tuning file coverage for the BMW X3 across 22 ECUs and 105 engine variants. Stock output ranges from 130 to 480 HP. Choose your controller to see matched variants, supported solutions and ECU software references. Each completed file is matched to the uploaded original, produced for the requested work and reviewed before delivery.

Match the original before tuning

The model name alone is not enough to select a calibration. Open the matching controller page and compare the ECU or TCU software reference with your read before requesting Stage 1, Stage 2 or solution work.
