What is the difference between the Contribution Input Object and the Contribution Main Input Object. The descriptions differ only in the first word: "The percentage of total fuel required delivered by these injectors" v. "Sets the percentage of total fuel required delivered by these injectors." Since both are input objects, I am not sure what the difference is between the two. Can anyone elaborate?
P.S. I reviewed how these are used in the GPR packages and adapted a similar working approach for my build. Nonetheless, I would like to fully understand the relationship between these two inputs.
