MAF vs Boost for Roots blower

[Dust]

So the easiest way is to run off of boost, but boost is kinda an on off thing with a normal roots blower. How would the MAF signal work for setting up a progressive spray compared to a boost based spray?

You have two choices to meter the spray:

1. Use a Boost vs RPM mappable controller - similar to the engine management
2. Mirroring the IDC - a composite signal that contains everything. Provided the car is tuned properly.

I?ve got a spare, mappable AIC with rpm/ vacuum/boost inputs. Do you happen to know how iot can be converted? I know it?s been done.
