FAQ

TL,DR: Hellen-Hyundai-PB and rusefi GDI pinout

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 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.

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!

Forum thread for dev board

Test Mule Wiring Diagram runs on rusEFI GDI!

Gasoline Direct Injection requires a few additional components on top of port injection:

  1. High voltage injection control - we have rusEFI GDI dev board which has clicked injector on a bench - Video.

  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?
