Am going aftermarket (not OFAB/OFAC) as per title whats the easiest one to fit yourself when going from MFI to EFI?
I have the block with the hole for the crank position sensor already (which is being rebuilt) and an EFI head but nothing else yet so gonna start collecting more bits i.e
EFI flywheel,
EFI inlet & TB hopefully with as much with it as poss,
XR3i accel cable & pedal
New injectors
Fuel pipe from filter to rail
Zetec coil pack (which one?)
What else do I need apart from the management ECU and loom?
Was planning on fitting the EFI flywheel when I get the block back and build it up on MFI first so that I can at least use the car while I source the extra bits I need.

For a cheap reliable setup that can be done in your own garage and then setup by yourself i would recomend megasquirt. Have a read here https://passionford.com/forum/ford-e...quirt-efi.html and www.extraefi.co.uk

I agree with juffer,
If you get the EFI inlet AND inlet loom every thing you need (practically) is on one plug. You will need extra wires for cps, lambda, ignition live, perm live but i think thats it can't remember with out the wiring diagram in front of me.
If you speak to Karlos, as he seems to be the man for MS he maybe nice enough to email you a base map so you can get your car running.

I would recommend the M-tech v4, its very simnilar to megasquirt except it is pre-built and comes with a warranty although there are other companies building megasquirt ecu's as well. Then all you will need is a Xr3i loom and away you go.

thanks guys will have a look through the MS stuff later as there is sed loads to read lol.
Have found a local guy who has loads of bits available, is there anything other than my list so far that I will need.
+Xr3i loom
Is there a way to tell if it is indeed an EFI XR3i loom?

only reason I suggested that is because you get all the sensors pre-wired, I can get these looms in mint condition for Ł30.00, for my conversion im stripping/binning all the loom which I dont need such as the lights, ancilliaries etc like you say and retaining the main engine loom. The edis is binned and the main sensors seperated and cut near the ecu conection plug. I am now left with the sensors with a factory soldered full length cable conected to it. All I do now is plug the sensors in, run the cables into the ecu location and join in the ecu harness. For Ł30.00 I thought is was a cheap soloution instead of cutting connectors and reconnecting within the engine bay, this way will keep it looking neat and factory.
This is my first attempt atr something like this so I may be way off with my methods. Im still learning
p.s. KArlos, that injector plug diagram wuill be getting some use this week
very useful

There is only the CPS, and coil pack plug that you use in addition to the inlet loom plug but as you say it would mean having full length cable for both those I spose.
I thought it worth putting that up as it does save a bit of time with a multimeter figuring out what all the pins do! Glad people find it useful

remember he is going from mfi to efi so he will have no injector plugs, ait intake temp sensor (i think) so he would have to source the plugs anyway, the connect them to the wires, but with the loom, he could use the standard ford inlet plug as per your sketch and it would look really neat in the bay, not to mention save time.
Its probably half a dozen of one and 6 of the other

As he already has a efi head then its really a case of un bolt the old and bolt on the new

if you use the series 1 mfi manifold then you can unbolt the inlet runners as you can on an efi manifold then just use the efi lower part for the injector holes and a cossie throttle body for the idle speed control valve and tps much better setup than efi fannymould
