I’ve been doing research on installing EFI on the comp with a stock ford intake. The wrecking yard here has a Bronco that I can get all of the parts I need for $250. Fast EFI has a retro fit system that will hook up to stock ford parts but a o2 censer needs to be installed into the wet exhaust. The censer needs to be kept dry & get hot. Has anyone out there installed a o2 censer it to wet exhaust?
From what I understand a stock marine GT 40 engines are running a open lope efi system . This system has no o2 censer for real time calibration. This efi system changes air /fuel mixture by temp, map & throttle only .
