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 11.1 340hp (250kW) 1695Nm, 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 11.1 340hp (250kW) 1695Nm, and we check the car over before writing to it.

See the full 11.1 340hp (250kW) 1695Nm page for every file and figure, the other engines on this C11, or all Caterpillar remapping.
