A: high voltage control of injectors, high pressure pump control logic and target fuel pressure control logic. GDI engines run on variable fuel pressure. Meaning ECU has to request specific fuel pressure and ECU has to control HPFP relief valve in sync with corresponding camshaft to actually build desired pressure.

1) High voltage injection control - we have [rusEFI GDI dev board](MC33816-PT2001-dev-board) which [has clicked injector on a bench - Video](https://www.youtube.com/watch?v=MI0gJ4th9Tg).

3) Target fuel pressure logic - we have nothing, but could be as easy as adding a simple table?
