Start/Stop Off explained — how it works, related DTCs and how Softechpro does it with automatic checksum correction.
Start/Stop Off permanently disables the auto start-stop so the engine never cuts at idle, set once in the ECU map (no button pressing every trip). Softechpro applies it directly in the ECU calibration and recalculates the checksum & CVN automatically, so the file is flash-ready.
Start/Stop Off is intended for off-road, motorsport, closed-course and export use in line with local law. It is one of the all-in-one services in Softechpro alongside DPF/EGR/AdBlue/DTC off and Stage 1/2/3 tuning.
