All written for the x25d specifically.
What STAGE 1 involves
Stage 1 is for a standard car with nothing fitted. We read the original file off the ECU, write a calibration developed for the x25d, then road or rolling road test it before handing the car back. Nothing is added and nothing is removed, so it looks and services exactly as it did.
It takes most of a day. We keep your original file, so it can go back to standard at any point. Figures here are for a healthy x25d, and we check the car over before writing to it.
See the full x25d page for every file and figure, the other engines on this X1, or all BMW remapping.
