Due to the diversity of components used by car manufacturers (airbag control units, seat occupancy sensors, software) we keep working over new devices. Unfortunately sometimes happens it that our emulator might not work in a car. There is always such a possibility and we do not hide it. Usually in such a situation we need to have a part of the seat mat with control electronics sent to us. Having it to compare, we are able to make a working emulator.
