Have a look at the stickies in the rs turbo section, there is a guide for cvh mfi-efi it should cover what you need to know.

If your using the Mfi bottom end your gonna have to either bore a hole for a cps bracket to pick up a signal off the efi flywheel or mount a trigger wheel on the crank pully with a bracket.You can buy these brackets new.

Hi iv got a zvh so it is a zetec bottom and has the crank sensor already what u need to no is what pins need changeing if i use a xr3i loom and a ofab ecu?

What I do no is the xr2i and 3i efi are the same loom.here is a guide on pin outs from 2i to ofab.This will sort you out.I did read a while ago that someone had plugged the ofab ecu into the 3i loom and it worked straight away with no changes.I think it depended on the yr of the car
