Carbs are only "better" because the EFI systems to date are way to expensive and require a bunch of test equipment.
You proved it can be done with "mix match" junkyard parts & a little effort.
Something occurs in the transition from AC to DC in the alternator & it makes EFI go 'crazy'. Some type of filter may solve that.
You build 3 prototypes & We'll test them. One in the west, 1 in the 'corn belt' & 1 one back east.
Give it some wacky name & Copyright that.
Or perhaps, a Canadian patient.
Where there's a will there's a way. The rest is history in the making.
