ECU Tuning Files and Chiptuning Service

Free Tuning Files Service delivers custom ECU solutions focused mainly on diesel engines, with selected petrol support on request. We prepare Stage 1 files, diagnostics-based corrections, and custom calibrations for modified hardware.

Looking for reliable ECU tuning files, Stage 1 remap, or DPF / EGR / AdBlue solutions? We mostly handle European diesel platforms including BMW, Audi, VW TDI, Skoda, Seat, Mercedes, Opel, and selected Subaru models. Start with our upload and contact page, review pricing on the pricing page, and check our diagnostics workflow before flashing.

Our workflow is clear: you send the original file, we analyze it, we return a tested calibration, and we stay available for revisions and logs. The target is always balanced performance, safe temperatures, and strong drivability.
