Staged injection is common on many engines where achieving adequate fuel supply through a single injector may adversely affect the ability to achieve good control of the air fuel ratio at light load and low rpm. Properly configuring staged injection is essential to ensure seamless operation as the secondary injectors begin injecting, while ensuring that you are achieving even flow from both sets of injectors.

In this webinar we will look at the correct configuration of staged injection on the Link G4+ ECU fitted to an FD RX7 with a 13B single turbo engine.
