Bob and I are on the same wave length. I would like to see a pic driving it from a
tach lead, MAP sensor and fuel pressure sensor. I would like to see 25 psi delta @
0-2K rpm rising to a constant 75 psi delta above 6K rpm. Use the maps to tune the
system from here..

This could be a stand alone unit or controlled by an analog signal from the ECU..

More later when we get the proto's done.
