All written for the xDrive 35i 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 xDrive 35i, 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 xDrive 35i, and we check the car over before writing to it.
See the full xDrive 35i page for every file and figure, the other engines on this X3, or all BMW remapping.
