hi all. been looking at imformation about gotech mfi and was wondering if someone could explain what batch firing for the injectors means. does this mean all four injectors fire at once and if so how does this not ruin economy and emissions by fuelling a cylinder/cylinders that are not on a firing stroke. i may be barking up the wrong tree but if someone could enlighten me then that would be great. also if this was bought diy from jamsport what other parts are needed, is it just an efi manifold with conversion plate and cossie injectors. cheers - neil
