thanks guys for your input,

i've been toying with an efi set up for my mc28 ,it's a long term project.
i planned on setting up a spliced pgmIII and logging its ignition curve through the rev range with a timing light and a cam degree wheel mounted behind the flywheel it would be the base setting for the efi, rpm activated outputs on the ecu for the power valves and exhaust sensors for the fuel.
i've spoken to some ecu manufactures and selected the unit i need

Matt are NH3 PGMII an obtainable part or are they a rare race part? it sounds like the unit i need to graph
