I think my success was pure dumb luck. I had an intake manifold welded up using aluminum tubes from Burns Stainless and a cut and modified aluminum intake manifold from Mazdatrix, with a TWM throttlebody that came with the injectors and fuel rail already installed which I purchased from Atkins Rotary. I am using the MicroTech ECU. It had a nice, slow idle from day one. I never did any pressure, volume, or injector calculations....proving my theory that it was pure dumb luck. I'm almost afraid to say what RPM it will REALLY come down to if you don't mind it running a little rough. I'm not sure anyone would believe me. (How about 300 engine rpm's and 150 prop rpm's). But it kinda spits and sputters with rpm's that low. Sorry I can't explain the reasons for my success. (Ignorance is bliss). Take care.
