New 1.6 Zetec SE "How to" OEM Ecu

"How to" OEM Zetec SE ecu with Pats info.

WARNING I WILL NOT BE HELD RESPONSIBLE FOR ANY LOSSES OR INJURY RESULTING FROM USE OF THE INFORMATION CONTAINED WITHIN THIS POST.


As this is Locost builders there are some people left that love to tinker and make things.
This is to give those people that are interested in running a ford efi engine on a budget a little more info on how the Immobilizer can be used out of the donor car.

The key to using the Ecu is the Pat's immobilizer. You must get at least one key with chip that is matched to the ecu.

You can not bypass it but you can use it.

I've recently did a 1.6 Zetec Se loom for a mate putting it in a Mojo. So I thought I would share .........

This one is a 60 pin with pre and post cat O2 sensor and knock control.






Ford Fiesta 1.6 Sport Zetec SE Ecu code CHCA

17)—White—Data link connector (Dlc) pin 13.
18)—Blue/white—Data link connector (Dlc) pin 10.
19)—Grey/purple—Data link connector (Dlc) pin 2.
20)—Black—Chassis earth separate from pins 16+40+60.
21)—Black—Idle control valve.
22)--.
23)—Black—Knock sensor.
24)—Black—Cam position sensor pin1.
25)—White/purple—Air temperature sensor (Act).

34)—Black—Injector 3.
35)—White—Instrument cluster.
36)—White/red—Data link connector pin7.
37)—Purple/yellow—Switched 12v.
38)—Grey/orange—Immobilizer aerial (Pats).
39)—Black/orange—Immobilizer status Led.
40)—Black/yellow—Chassis earth.
41)--
42)--
43)—Brown/white—Clutch pedal position switch.
44)—White—Pre cat O2 sensor.
45)—Black—Alternator.
46)—Brown/red—Sensor common.
47)—Black__Throttle position sensor.
48)—White/red—Post cat O2 sensor.
49)--
50)—White/Blue—Mass air flow meter.
51)—Black/blue—Post cat O2 sensor.
52)—Black/blue—Instrument cluster Mil.
53)—Black/blue—Fuel pump relay switched earth.
54)—Black/yellow—Ac.
55)—Black—Crank position sensor (Cps) pin 2.
56)—Black—Crank position sensor (Cps) pin 1.
57)—Purple/yellow—switched 12v.
58)—Black/orange—Coil pin 1.
59)—Black/green—Coil pin 3.
60)—Black/yellow—Chassis earth.

Power distribution for the ecu.



The pats Immobilizer

The Transceiver / aerial.



The plug



How its wired, plus the status led often found in the clock. This tells you if the Immobilizer is armed or not and will give blink codes.



The fuel Injectors





To be continued if there is any interest ?????????????????????

ps are the individual circuit diagrams better than just the pin outs and plugs. ????????????????????


cheers

For myself building up the loom with the pic at a time is the way forward, it's ho you would logically build it up.

I did this in 2012 and I have not regretted it:

I even got the ECU reshipped to give more poke.

Your timing is impeccable! Here's how I left mine this morning:
Mojo wiring

This is a MK1 Focus 1.6 SE (post cat sensor and knock sensor) being grafted on to a Fiesta/Puma hybrid loom already in my Mojo, and my next job was to start sorting out which wires I needed to keep and which ones could be removed (PAS, AC etc). I shall keep a very close eye on this thread!

Hi can you clarify if the fan control outputs are switched 12v or switched earth please?

Switched earth but its not a standard on / off relay and it depends if it's got ac as it has a two stage fan set up with resistors.

I never bothered with it as I used external controlle. I will get around to it for the Rs.

I'm just trying to save a few quid as those external rad fan switches with the fancy alloy housing are expensive. I noticed the two fan connections and was just assuming that there would be two fan switches, coming on at different temperatures and controlling two fans.
Resistors though? Seems a bit odd - unless there is actually only one fan with two different speeds. That must be it I think.

I will see if I can sort out a wiring diagram over the week end.

Glad i found this post...
I bought two Zetec 1.8 engines with the full ecu's for a cost to me of about £200.
one from a 1999 mondeo (T reg) has a 104 pin ecu and one from a 2001 Focus (51 reg) which has a 60 pin ecu.....this engine only has one coolant sebsor behind the alternator, the mondeo has two on the thermostat housing.
it appears the Focus has a Pats system fitted and i have the ign key, but do i need it? is it integrated into the ecu like the 104 pin ecu's?

You want the zetec e post this is the all alloy fiesta / puma engine. Some of the diagrams are better on this one.

Yes you will need the chip from the matching key. Doesn't matter if it's 60 pin or 104 anything newer than an M reg has pats.

Don't suppose you could post a link for please?
I know of your posts on the 104 pin ecu....and that will be in my other car .but the 60 pin ecu is a problem.

Off at a tangent, i have a spare 2.0L pinto carb and Xflow manifold as well as several complete EDIS systems removed from various Fiesta's/ Fords.....i am tempted to fit this to one of my cars and fit the full injection set up to my other car, might be interesting to compare the two side by side.
but i think the edis systems need a megajolt mappable ecu to time the sparks, is that also true if the edis system also has the map sensor with it?

If the Edis has a built in map sensor and it has a red top and says Esc then it is a little differant to an Edis4 and has a controller built in, but very basic. It will run a basic zetec on a single carb if your not after any real performance or economy. It's an 8v map.

An edis4 requires a controller like a megajolt or it just gives a flat 10 deg
