this bfin is F**** nuisance mate bought a restored from vehicle bfin coincidently it was a fiesta zetec 16 cleared ecu with snapon code reader bfin installed no problems after taking ecu memories into itself. I have a focus with a mis used the b fin code reader out of interest and it locked my ecu Ford couldnt deal with an ecu that says its a fiesta so over to the local superchip dealer he coiuldnt with the help of a key programmer specialist unlock the pats code either. My ecu is now at super chips for sorting at considerable expense so far down to me my advice go 4 a plug on chip in future and do the contact cleaning thing get the laquer of the terminals plenty of usa providers will post. Europe is also live with specialist chips I think theres is an optimistic view about hacking these items Is your unit for a 20 focus cos i dont want it im gonnan try the e bay 5.00 resistor and let u know.
