xr3iAlex

Hi all just got a xr3 carb engine to put in my escort 1300 that is on carb. I broke a EFI xr3i so i had the loom apparently it would be easier to put a full mfi loom in then mess around snipping the wiring and ect ?
I was just wondering if the efi clocks are the same. and do all xr3is have electric mirrors, thanks !
Also how long does it take to put a full loom in ?

The EFi cars run whats called a wasted spark system which means each time the cylinder fires it sparks twice. This means if you run EFi clocks on a non EFi car they will read half the value they are supposed to i.e. showing 1krpm when the engine is doing 2krpm. You'd find it easier to source a set of MFi clocks

An alternative is a Ł30 tacho driver works perfect as I have one.

the eec4 tends to use the same rev counter as conventional coil systems as it has a dedicated rev counter signal from the eec4 ecu
not 100% sure they are the same on your escort but they are on a BT escort cosworth weber and an LT eec4 escort cosworth

How can you tell the diffrence between mfi clocks and efi ?

The EFi clocks have EFi in white on the tacho
