The memory for software and data is implemented as a programmable component into ECUs for a long time now. Ever since these components are erasable even as an assembled part of the ECU more and more vehicle manufacturers chose to provide the possibility to re-load / replace the software and data contents of the respective control unit in addition to the analysis and error detection mechanisms.

By doing so vehicle manufacturers achieve the ability to work knowledge found after the production has started into already delivered cars resp. their ECUs.

With the help of this interface the tuning technician is able to load a modified file into the ECU without the previously unavoidable hassle of mechanical jobs on that very unit.

no need to dismantle the ECU
shorter waiting periods for the customer
the possibility to reverse the software upgrade without any trace e.g. when selling the car
