TL,DR: [Hellen-Hyundai-PB](Hellen-Hyundai-PB) and [rusefi GDI pinout](GDI4)
|
||
|
||
## Q: What are key differences between port and GDI?
|
||
|
||
## A: high voltage control of injectors, high pressure pump control logic and target fuel pressure control logic
|
||
|
||
## GDI Status
|
||
|
||
TL,DR: Summer 2023 progress is happening, GDI4 rev D board is ready for prime time and Kia has driver around the block!

Gasoline Direct Injection requires a few additional components on top of port injection:
|
||
|
||
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).
|
||
|
||
2) High pressure fuel pump solenoid control - we have a working implementation!
|
||
|
||
3) Target fuel pressure logic - we have nothing, but could be as easy as adding a simple table?
