heheh more bloody hassles with yr engine

if u r runing std ecu u need the tfi
its just like an ignition module
im not sure if its a dumd or a smart module
u might be able to replace it with an msd but i would not risk it
look at msd website see if they have diagrams for msd on an efi windsor
you cant bypass it otherwise ecu will burn like vinctoria has the past few days

dont buy 2nd hand one
they are not that dear for new one

bout 100 odd dollars
