[Diy_efi] 5 port head?

[Buck Williams]

reasonnn i askedd is thatt since the centerr intakee is shared dual for2 and three that the injector sequeance should be simple,there are only two firing orderss for a4s ,1342 and 1243 in any case the firing an intake sequaence for the center set cylinders are widely sepearateddd for intake i events,, so there could hardly be any cross fuelling or puddlaing of fuel,  for 4 injector systemm the fuel and airstrream is goaing to gott to the cylinder ingesting at that particular time,, seemsss u shosuld be able to add two injectors in the intake stream for the centerr paired cylinder sets with each injector firiang at its appropriaate cylinder without the added problems of probrammingg for double the time firinag for just one injector for two cylinders, the airstreeam is going to the cylinder drawaing  at athtqt time, years ago i put mechanical bosch injection pump on old rd450 gash internationalll six with siamesed ports, i ran out of fuell for ;the 450 cubes, did not have enoaugh injection, but it ran fine and could find no evidenace of puddling, buck, i believeee i would plumb and injectr the enginee as if the center intakeee duct were a  cylinder port with two injectorsss and i also believe the engine
