Ive searced through everything and cant find a straight answer.Maybe its a dumb quistion but is there a way to reprogram an ecu from a diffrent engine/trans to work on my bronco?Im having promble with the fuel pump not cutting off and tracked it down to the ecu.So the closes one i found was a couple letters/numbers off.Now it starts right up but runs eratic,with a bad miss.Thanks for any help.
