Whilst there are few stock engines that come with secondary injectors (the notable exception being many Mazda rotaries) secondary staged injection is a common modification, in particular used whenever large injectors are required, but where it is desirable to keep smaller injectors for smoother low RPM performance. +## Hardware Configuration +The hardware configuration of the staging outputs depends greatly on the board in use, the engine itself and the fuel injector arrangement. + +The table below outlines the number and channel configuration of the fuel channels required based on the cylinder count and fuel mode: + +| | **1** | **2** | **3** | **4** | **5** | **6** | **8** | +|----------------|---------------------------------|-------------------------------------|-----------------------------------------|---------------------------------------------|-----------------------------------------|-------------------------------------------|---------------------------------------------| +| **Sequential** | **Min Inj#:** 2
