AUDI S4
AUDI S4 tuning files
Tuning file coverage for the AUDI S4 across 14 ECUs and 200 engine variants. Stock output ranges from 230 to 354 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.
