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 12.5 340hp (250kW) 2102Nm, 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 12.5 340hp (250kW) 2102Nm, and we check the car over before writing to it.

See the full 12.5 340hp (250kW) 2102Nm page for every file and figure, the other engines on this C13, or all Caterpillar remapping.
