View Full Version : zetec engine ecu

I know most people use bike carbs but I would much prefer to keep the standard injection.
Is this possible? Still trying to get my head round this pats thing but if I used engine, ecu, keys, transponder from the same car. Would that work or need aftermarket ecu and loom?

Yeah I did know there was a mod needed to the inlet, there were companies making them but can't seem to find any.
I can't seem to find anything on the wiring either, which has to be the hardest part.
I'm sure there will be others that have done this whether it be a roadster or any other car.
Let me know how you get on

There is a guy in Chopwell that can possibly take the pats off.

I'm running a Zetec 2.0 from a 1993 Mondeo with standard intake and ECU. I'm building a left hand drive roadster. You will have a hard time routing the steering shaft around the manifold (but it is doable), the access to your master cylinder will not be very simple, but otherwise it is not impossible.
Here's a pic of how much space you should expect:

My current problem is that the diameter of the throttle body flange is 70 mm, but the space between the flange and the bonnet is around 60 mm. So it's not very easy to fit the intake bend under the bonnet, and scoops don't normally extend there.

i'm guessing you were lucky enough to find an ecu without PATS.
I see that is very tight but shows that it is possible.
flyerncle. I didn't know it was possible to remove the PATS system but that would be handy, I was also thinking it would be useful to keep as would count as a security device for SVA.

I would have thought that as long as you have everthing from the original car it should work.
I intend to use a X20XEV out of my old Vectra and kept the ECU, transponder, ignition barrel and keys for this very reason.

You could try Big wasa on here or on Locost fourm he has working in his car

My understanding is that all early Zetecs were without PATS. Definitely Mondeo of the 1993 model year. Having a pre-1995 engine is useful in the sense of exhaust emissions, too. Later ones practically need a catcon to pass the emissions test.
I didn't know it was possible to remove the PATS system but that would be handy, I was also thinking it would be useful to keep as would count as a security device for SVA.
The problem with PATS is that it's not very well documented, but people say that it can be disabled with just a couple of wires.

Terry, He is a wizard with micro electronics and has removed them from VAG ecu's.
Albert,look at Fiat Punto fluid resovoir,you could use the fittings to make a remote resovoir if you extend the pipes.

You need to determine whether your donor has pats, some early cars did and some didn't, my '93 RS did. Try to find a car that is non-pats, there are a few people who can de-pats if you've already got the car but you do need to be sure you have pats before de-patsing otherwise you'll ruin the ECU. Likewise don't mess about trying to make it work, if you've missed an item of the pats system (for example the LH headlight is not connected) then it'll lock the ECU and it has to be sent to Ford HQ for a reset.
Personally I would use bike carbs and megajolt as you can unlook more power that way, with the stock system you have the same power as the donor which for the 2.0L is way down on what you can get out of it.:D

I see, didn't realise there were other items that would affect it such as headlights.
I don't have a donor but one without pats is going to be very rare.
The reason for doing this is that there are never any pre 95 engines for sale and I would also prefer a newer engine as there are lots around cheap and should be more reliable.
Another question, do all zetec's have the same wiring/connectors?
Could I use a newer engine but try to find a ecu/loom from a car without pats?
And when I find a donor, pats or no pats. How hard is it to remove the loom?
I've heard it can be a bit of a nightmare.

You are way of the mark.
The immobilizer can be armed and disarmed with it sat on my dinning table.

The eec 4 +5 ecu's are not of a canbus design.
The 97 on ecu's are much nicer than older ecu's due to suporting Obd2. I can connect my phone to the ecu and monitor its perimiters.
Why disable the pats ? Its very easy to use if you have the rdif chip from the key and gives your kit what was a thatcham aproved immobilizer.
Ive been doing them for years, its a much better set up than webers and bike carbs and will pass iva (with a cat) with NO messing.
Any one want to donate a jag s type as I fancy a new challange and it should also be ford bassed.

Westfield played with the zetec and standard mani for a bit.
They used a plenum that was thought to be from a peugeot and a joiner.

Looks like you really know your stuff with all this, It would be handy to keep the obd2 connector even just to read fault codes.
You should do some sort of guide as to how you have set yours up, looks like you have spent a lot of time and effort figuring out the setup.

Ive thought about doing an "how to" but there are just to many vairables to cover all the ecu's. Ive done a year and model specific set of instrucion but out of the six people that have had a go, only three have got it running.
Functions / pin numbers and colours are differant depending on model spec and year.
Getting it wrong can cause damage or even fire.
None are that hard when you know how it works. But I do love engine managment systems and the engines.
I am a big fan of using the oe ecu. It starts on the button and idles as a factory car would. It has instant power and torque with good economy. Best of all its plug and play, there is no tunning.
I will agree, power will be down a touch on other set ups but not by as much as you would think. A four branch mani and a free flowing inlet set up should see a well proven (in fast ford circles) 150bhp.
165 is prety much the max on a zetec with out head work and cams.
So what price is the 15bhp worth to You ????????? The more you make the less you spend.....
To give you an idea....
Ecu and rdif chips.....just nipped up the post office to pick up a £10 ebay ecu. Came with two rdif chips. Just to show how few wires are needed to arm and dis-arm the immobilzer, a picture.

good luck matie ! ive used the x20xev out of an omega and the immobilizer system wants to see doors windows the lot and if you leave it too long the transponder of the key/ ignition barrell un syncs ! or it did on mine ive had to go down the megasquirt ecu route and thats being a real pain as i cannot get an rpm signal for the ecu !
but the x20xev does look sexy with a set of home made throttle bodies on it
