With dynamic range, we are talking about pressure range that pump can provide with PWM controller. 40- minimum for jet, 160 ? maximum pump can provide.
According to the flow graph this range of pressure will allow you to vary amount of delivered water only in the range of x2. Say 200cc at 40PSI to 400cc at 160PSI.
This range may or may not do, depending on your motor?s specifics and WI system tune.
Using 0-5VDC from MAF is not a bad set up but not perfect. As from what I understand water delivery curve is not liner. It must spike at maximum torque and follow the engine load.
I will try to do some calculations when I will manage to get volumetric efficiency table for my AUDI motor. Until then I am guessing.
Richard L, did I miss anything?
