hey guys, i removed an ecu coded 2FCD from my fiesta, its not the normal ecu code that most fords come with any chance that someone can identify it?

as basically i'm going to be installing a 1.8 115ps engine from my escort into the fiesta for temporary basis until i can find a decent 2.0 with ecu, so can i use the 2FCD ecu, if not can my 1.8 SLUG coded ecu with pats work??

[sjoyce666]

2FCD is the 105ps XR2i ECU for external EDIS and doesnt have PATS to worry about

would the ecu work with the 1.8 115ps engine i'm going to install? and external edis? if i change the ecu to my SLUG pats ecu would i still need the external edis??

as long as you have the key for the slug ecu then the SLUG will do everything and you dont need the edis as it is built into the ecu you need it for the other one as it isnt built in

[SLEEMAN]

i see but problem is though that my fiesta's wiring doesn't have the pats system wired in. its an xr2i 16v 105ps. was just double checking if the 2FCD is the correct ecu for the xr2i as most ecu's are coded with words unlike this one is just a code.

is there a way i can by pass the pats on the ecu or if i just plug it in would it work seeing theres no wiring to a pats system?

also seeing that the external edis system is already wiring in the existing loom do i have to cut it out when i put the slug 1.8 ecu in? or can i still keep it there so i don't make any complications with wiring!!

[4992jk1]

if you want to use slug you need to have the rest of the pats system, as without it the ecu will never fire an injector and i think it also refuses to spark either, to use 2FCD you will need to redo the wiring loom to remove the edis and wire the sensors into the correct places, if you need a pinout i think i have one for that ecu though.

[sjoyce666]

2FCD is external EDIS so you dont need to do anything to your loom to use that one. This is the original XR2i 105ps ECU and the code may be different to others you have seen but it is a normal code

To use the SLUG ECU you need to know if it is external or internal PATS and EDIS

It will only work on your current loom if it is external EDIS and external PATS. If it is internal EDIS it will need pins changing on the loom, if it is internal PATS then you need all the PATS system from the original car

well i know that the escort it will be removed from has the pats system going around the ignition barrell with the wires going to the ecu. and in an escort 1998 mk6 where would the external edis be?

or would it be easier if i could find a 130spec ecu from a xr3i escort or rs1800 and use that with the 1.8 engine along with 130 spec cams, maf and TB?? as i have them all spare?

[MB7201]

SLUG will have internal pats and internal edis. To use it you need to do pin swaps on the ecu connector and add 3 extra wires for the pats tranceiver.

[4992jk1]

if you decide to use the slug i definitely have the pinout for that, but i dont know which way round the tranceiver wires go. and im told the pinout for 2FCD is the same as the pinout for 1AFA which i have but i cannot guarantee that.

[SLEEMAN]

where do i need to put the wires in for the pats transmitter? and which wires do i have to swap over???

[4992jk1]

well the transceiver needs to go by the barrel and the wires go direct to the ecu, and as for which wirse need swapping over there are a few as the edis unit needs removing so you need to move the crank sensor and the wires for the coil ect and the hego will need adding in as i dont think 2fcd has it

[SLEEMAN]

bloody hell sounds more like hassle lol. would it better if i just plugged in a 2.0 ecu non pats lol

[simps]

i have got this same ecu in my car.

which ecu's are a direct swop that give 130 spec? as i have fitted 130 spec cams

[MB7201]

Probably rs1800 with external edis i.e. not the CULT one.

If you are planning on putting the 115bhp engine into a 105bhp xr2i you will only end up with the same power again and be needing the standard ecu.

[SLEEMAN]

well the 1.8 is just a temporary bolt in job so i can build up a nice 2.0 or better to bolt in for when it comes to track days. as i want to get the fiesta on the road and running as a daily hack around till i get my escort stripped down, ready for some major bodywork needed doing. so when thats finished and the other 2.0 engine is fully built to my specs, possibly to turbo or supercharged specs still deciding on what i want or what i can afford lol. then the car will be tracked up big spec i hope lol

so basically i would prefer an ecu to just plug in so i can bolt the engine in and get it running, although if it makes it easier i do have 130 spec cams, throttle body and maf so if the 2.0 ecu can be a simple plug and leave it be then great but if there is any other ecu that i can find alot easier than the 2.0 ones then by all means please say so. i just want to get it running lol!

[MB7201]

Well only do the swap if there is something wrong with the current engine otherwise it's a waste of time. The ecu will run it fine as the engine will be the same spec. The 2.0 ecu also needs a similar amount of pin changes.

[SLEEMAN]

thats the problem theres no engine lol!! until the other 1.8 is removed so the current 2fcd ecu is still good to run the 115ps engine then?

[MB7201]

Yes, it will be fine.

[SLEEMAN]

goooood!!! cheers matey!! i won't sell the ecu then lol!!

cheers guys for all your help!!
