BMW M3
BMW M3 tuning files
Tuning file coverage for the BMW M3 across 4 ECUs and 5 engine variants. Stock output ranges from 195 to 530 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.
