depends on what management you want to run, mate. its easy enough to chop the mfi loom out of a full s2 loom and splice a different engine management loom into it

iirc you could use the loom from an efi escort xr3i to fun fiesta turbo management but its bastard expensive to tune if you can find anyone to do it.

depending on what sort of power you're after, it's probably better to run cossie or aftermarket management imo
