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 7.2 Acert 234hp (172kW) 732Nm, 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 7.2 Acert 234hp (172kW) 732Nm, and we check the car over before writing to it.

See the full 7.2 Acert 234hp (172kW) 732Nm page for every file and figure, the other engines on this C7, or all Caterpillar remapping.
