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 S40 400hp (294kW) 1800Nm, 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 S40 400hp (294kW) 1800Nm, and we check the car over before writing to it.

See the full S40 400hp (294kW) 1800Nm page for every file and figure, the other engines on this Stralis, or all Iveco remapping.
