- **Injector Port Type:** Option isn't used by firmware. Selection currently does not matter
- **Number of injectors:** Usually the same as number of cylinders (For port injection)
- **Engine Type:** Whether the crank angle between firings is the same for all cylinders. If using an Odd fire engine (Eg Some V-Twins and Buick V6s), the angle for each output channel must be specific.
- **Stoichiometric ratio:** The stoichiometric ration of the fuel being used. For flex fuel, choose the primary fuel. This field is automatically set by the req. fuel calculator after being used.
- **Injector Layout:** Specifies how the injectors are wired in
- **Paired:** 2 injectors are wired to each channel. The number of channels used is therefore equal to half the number of cylinders.
- **Semi-Sequential:** Semi-sequential: Same as paired except that injector channels are mirrored (1&4, 2&3) meaning the number of outputs used are equal to the number of cylinders. Only valid for 4 cylinders or less.
