Does anyone has experience to replace the injector himself. It seems the replacement works are simple but only thing got problem is how to enter the figure into ECU via INPA.

I search the internet a whole night but can't find any INPA MSD81 to do this data input for N55 engine

For N54 engine, there has two figures required for ECU. Energy and flow rate but I only see one figure is difference on N55 injector which near the fuel connector. Not 2, just wonder I need two figures or actually only 1 has done all the things well.
