ages ago i rad something about there needing to be pin changes when using the xr3i loom and ofac ecu,i saved the basic info but not the reason why,but im sure whoever it was who posted says it was something about the fueling

here is what i got

1) Pin no. 8 (brown) needs moving to pin 27, which is empty (CO adjuster signal wire)
2) Pin no. 27 (brown/yellow) needs moving to pin no. 45
3) EDIS Module pin 2 (blue/yellow) may now be disregarded as it is not used by the 0FAC ECU (pin 28 on ECU).

i had a fiesta turbo loom whice came with my ecu and compared the two,the only difference between the two was the brown/yellow wire,the brown one that it says needs moving was already in the same place on both looms but the bwown/yellow needed moving on the xr3i loom as it sways above
